The high potential is greater than the low potential. In addition, multiple signals in various embodiments of this application correspond to a first potential and a second potential. The first potential can refer to an effective potential, and the second potential can refer to an ineffective potential. The first and second potentials only represent that the potential of the signal has two states, and do not represent that the first or second potential has a specific value throughout the text. Optionally, in the embodiments of this application, the material of the N-type transistor may include oxide, and the material of the P-type transistor may include low-temperature polysilicon (LTPS). Here, the transistor material refers to the material of the active layer of the transistor. Of course, the materials here are for illustrative purposes. Provided the circuit includes both N-type and P-type transistors, it can also be called an LTPO circuit.

[0047] With the continuous development of display technology, a series of display devices that can switch between privacy and shared displays have emerged. Common display devices include those using Organic Light-Emitting Diode (OLED). Among them, OLED has become the mainstream solution due to its inherent advantages such as self-illumination, ultra-thin form, and high contrast.

[0048] For example, refer to Figure 1In a display device that can switch between privacy display and shared display, the display panel can be divided into a shared area for shared display and a privacy area for partial privacy. The shared area has a built-in shared light-emitting unit, and the privacy area has a built-in privacy light-emitting unit.

[0049] Here, it can be understood that a privacy display refers to a display panel where pixels emit light at a narrow viewing angle, making the displayed information visible to the user directly in front of the display panel, but invisible to bystanders, such as those to the side of the display panel. This prevents the displayed information from being seen by bystanders and avoids information leakage. A shared display, on the other hand, refers to a display panel where pixels emit light at a wide viewing angle, making the displayed information visible to users from all directions of the display panel, facilitating information exchange and sharing. The terms "narrow viewing angle" and "wide viewing angle" are relative concepts. The privacy light-emitting unit can be designed as a narrow-viewing-angle light-emitting device, while the shared light-emitting unit can be designed as a wide-viewing-angle light-emitting device. Both can be implemented using the OLEDs described above, referred to as privacy OLEDs and shared OLEDs, respectively. Of course, the type of light-emitting element is not limited to this; for example, in other embodiments, mini-OLEDs can also be used to design privacy light-emitting elements and shared light-emitting elements.

[0050] Furthermore, structurally, it can be understood that in the privacy protection area of ​​a display panel, a light-blocking layer (such as a black matrix layer) is typically placed above the side of the light-emitting element furthest from the substrate. This is combined with light-concentrating components such as microlens arrays (MLAs) and efficiency enhancement structures (EES) to compress the angular distribution of the emitted light, thereby reducing the viewing angle and achieving a narrow-view privacy protection effect. Conversely, in the shared area, a light-blocking layer or other layers that do not reduce the viewing angle are typically not designed above the side of the light-emitting element furthest from the substrate. Light-concentrating components such as MLAs and EES are also not used to ensure a wider viewing angle, meeting the requirements of wide-view shared displays.

[0051] The aforementioned display devices capable of switching between privacy and shared display have a wide range of applications, including in-vehicle displays and integration into mobile terminals such as smartphones, laptops, and tablets. For example, in the automotive field, with the development of smart cockpits, a continuous, integrated screen spanning from the driver's side A-pillar to the passenger side A-pillar is becoming a mainstream trend, aiming to provide a better visual immersive experience for in-vehicle users. However, because the driver and passenger sides share the same continuous screen, a safety hazard exists. For instance, the passenger viewing non-driving information may distract the driver. Therefore, for driving safety considerations, such as... Figure 1As shown, the display area on the passenger side can be set as a privacy screen to avoid distracting the driver. The display area on the driver's side can be set as a shared area, for example. Furthermore, the size of the privacy screen can be dynamically adjusted based on the viewing needs of different content. For example, combined with... Figure 1 In some scenarios, as shown in 1a, the area of ​​the privacy protection zone can be smaller than the area of ​​the shared area. In some scenarios, as shown in 1b, the area of ​​the privacy protection zone can vary to be larger than the area of ​​the shared area.

[0052] However, in traditional solutions, as described in the background, a one-to-one pixel architecture is often used to implement shared display and privacy display separately, that is, independently configuring pixel circuits to drive the shared light-emitting element and the privacy light-emitting element to emit light respectively. For example, combining Figures 1 to 3 In the shared area, each pixel includes, for example: Figure 2 The diagram shows a shared pixel circuit P1 and a shared light-emitting element L1. The shared pixel circuit P1 drives the shared light-emitting element L1 to emit light, thus achieving shared display. In the privacy area, each pixel includes, as shown... Figure 3 The privacy pixel circuit P1 is shown, and a privacy light-emitting element L1 is also shown. The privacy pixel circuit P1 is used to drive the privacy light-emitting element L1 to emit light, thereby realizing privacy display.

[0053] Optionally, the shared pixel circuit P1 and the privacy pixel circuit P1 can have the same structure, such as combining... Figure 2 and Figure 3 Both the shared pixel circuit P1 (sharing) and the privacy pixel circuit P1 (privacy protection) can be a 7T1C architecture, comprising seven transistors M1 to M7 and one capacitor C0. Of course, the shared pixel circuit P1 (sharing) and the privacy pixel circuit P1 (privacy protection) can also have different structures. This application does not limit this aspect. (Combined with...) Figure 2 and Figure 3 It can be seen that: Transistor M1's gate can be connected to node S1, its first terminal can be connected to node S2, and its second terminal can be connected to node S3. Transistor M1 can transmit a light-emitting drive signal to node S3 in response to signals transmitted to node S1 and node S2; transistor M1 is also the driving transistor in the pixel circuit. Transistor M2's gate can be connected to the gate signal terminal (Gate), its first terminal can be connected to the data signal terminal (Data), and its second terminal can be connected to node S2. Transistor M2 can control the connection and disconnection of the data signal terminal (Data) and node S2 in response to the gate drive signal provided by the gate signal terminal (Gate), allowing the data signal provided by the data signal terminal (Data) to be transmitted to node S2 to charge node S2. Transistor M3's gate can be connected to the gate signal terminal (Gate), its first terminal can be connected to node S1, and its second terminal can be connected to node S3. Transistor M3 can control the connection and disconnection of nodes S1 and S3 in response to the gate drive signal provided by the gate signal terminal (Gate). Transistor M4's gate can be connected to the scan control terminal S1, its first terminal can be connected to the initial power supply terminal Vinit, and its second terminal can be connected to node S1. Transistor M4 can be used to switch in response to the scan control signal provided by the scan control terminal Scan1, controlling the on / off state of the initial power supply terminal Vinit and node S1. Transistor M5's gate can be connected to the light emission control terminal EM1, its first terminal can be connected to the charging power supply terminal VDD, and its second terminal can be connected to node S2. Transistor M5 can be used to switch in response to the light emission control signal provided by the light emission control terminal EM1, controlling the on / off state of the charging power supply terminal VDD and node S2. Transistor M6's gate can be connected to the light emission control terminal EM2, its first terminal can be connected to node S3, and its second terminal can be connected to node S4. Transistor M6 can be used to switch in response to the light emission control signal provided by the light emission control terminal EM2, controlling the on / off state of nodes S3 and S4. The gate of transistor M7 can be connected to the scan control terminal S2, the first terminal of transistor M7 can be connected to the initial power supply terminal Vinit, and the second terminal of transistor M7 can be connected to node S4. Transistor M7 can be used to switch in response to the scan control signal provided by the scan control terminal S2 to control the on / off state of the initial power supply terminal Vinit and node S4, so that the initial power signal provided by the initial power supply terminal Vinit can be transmitted to node S4 to reset node S4. Capacitor C0 can be connected between the charging power supply terminal VDD and node S1 to store and stabilize the potential of node S1.

[0054] And, for Figure 2For the pixel shown, node S4 can be connected to the anode shared by the shared light-emitting element L1, and the cathode shared by the shared light-emitting element L1 can be connected to the pull-down power supply terminal VSS. Thus, transistor M7 can reset the anode shared by the shared light-emitting element L1. Furthermore, under the control of the aforementioned signals, the light-emitting drive signal generated by transistor M1 in the shared pixel circuit P1 can be transmitted to the connected shared light-emitting element L1, driving the shared light-emitting element L1 to emit light.

[0055] for Figure 3 For the pixel shown, node S4 can be connected to the anode of the privacy light-emitting element L1, and the cathode of the privacy light-emitting element L1 can be connected to the pull-down power supply terminal VSS. Similarly, transistor M7 can reset the anode of the shared privacy light-emitting element L1. Furthermore, under the control of the above signals, the light-emitting drive signal generated by transistor M1 in the shared privacy pixel circuit P1 can be transmitted to the connected privacy light-emitting element L1, driving the privacy light-emitting element L1 to emit light.

[0056] However, as mentioned in the background, this one-to-one pixel architecture, under current high PPI display specifications, has limited pixel layout space and is difficult to wire. In other words, it is difficult to reliably implement within a limited space, and it is difficult to simultaneously achieve high PPI and privacy / sharing switching designs. PPI, or pixels per inch, is used to characterize the resolution of a display panel.

[0057] Based on this, embodiments of this application provide a design that supports one-drive two-pixel switching of local privacy shutter positions. First, refer to Figure 4 The diagram schematically illustrates a one-to-two pixel architecture. In this one-to-two pixel architecture, each pixel includes: a pixel circuit P1, a shared light-emitting element L1, and a privacy-protecting light-emitting element L1. The pixel circuit P1 can be, for example, a... Figure 4 The 10T1C architecture shown includes 10 transistors M1 to M6, M7_1, M7_2, M8_1, and M8_2, and one capacitor C0. Among them, transistors M1 to M6 and capacitor C0... Figure 2 and Figure 3 The structures shown are the same, so they will not be described again.

[0058] The gate of transistor M8_1 can be connected to the shared light-emitting control terminal EM, the first terminal of transistor M8_1 can be connected to node S4, and the second terminal of transistor M8_1 can be connected to the anode of the shared light-emitting element L1. Transistor M8_1 can be used to switch in response to the shared light-emitting control signal provided by the shared light-emitting control terminal EM to control the on / off state of node S4 and the shared light-emitting element L1, so that the light-emitting drive signal transmitted to node S4 can be further transmitted to the shared light-emitting element L1 to drive the shared light-emitting element L1 to emit light. The gate of transistor M8_2 can be connected to the privacy light-emitting control terminal EM, the first terminal of transistor M8_2 can be connected to node S4, and the second terminal of transistor M8_2 can be connected to the anode of the privacy light-emitting element L1. Transistor M8_2 can be used to switch in response to the privacy light control signal provided by the privacy light control terminal EM privacy, so as to control the on / off state of node S4 and privacy light element L1 privacy, so that the light driving signal transmitted to node S4 can be further transmitted to privacy light element L1 privacy, driving privacy light element L1 privacy to emit light.

[0059] Transistors M7_1 and M7_2 are similar Figure 2 and Figure 3 The transistor M7 shown here, in a one-to-two architecture, can be connected to the scan control terminal S2, the initial power supply terminal Vinit, and the anode shared by the shared light-emitting element L1. It can also be used to control the on / off state of the shared anode of Vinit and L1 via the scan control signal provided by the scan control terminal S2, thereby resetting the shared anode of L1. Similarly, transistor M7_2 can be connected to the scan control terminal S2, the initial power supply terminal Vinit, and the privacy-protected anode of L1 via the privacy-protected light-emitting element L1. It can also be used to control the on / off state of the shared anode of L1 via the scan control signal provided by the scan control terminal S2, thereby resetting the privacy-protected anode of L1.

[0060] That is, transistors M1 to M6, and capacitor C0 can be used as pixel circuits for both the shared light-emitting element L1 and the privacy light-emitting element L1. Transistors M7_1 and M8_1 can be dedicated circuits for driving the shared light-emitting element L1, and transistors M7_2 and M8_2 can be dedicated circuits for driving the privacy light-emitting element L1. In this way, reliable driving of one device to two devices is achieved.

[0061] Optionally, Figures 2 to 4In the pixel structure shown, each transistor is a P-type transistor. Accordingly, each P-type transistor can turn on in response to a low-potential signal received at its gate, thereby controlling the first and second terminals to conduct; each P-type transistor can turn off in response to a high-potential signal received at its gate, thereby controlling the first and second terminals to disconnect. Thus, it can also be seen that for... Figure 4 In the illustrated structure, when the potential of the shared light emission control signal provided by the shared light emission control terminal EM is low, the control transistor M8_1 is turned on, causing node S4 and the shared light emission element L1 to conduct together. This allows the light emission driving signal transmitted to node S4 to be further transmitted to the shared light emission element L1, driving it to emit light. Similarly, when the potential of the privacy light emission control signal provided by the privacy light emission control terminal EM is low, the control transistor M8_2 is turned on, causing node S4 and the privacy light emission element L1 to conduct together. This allows the light emission driving signal transmitted to node S4 to be further transmitted to the privacy light emission element L1, driving it to emit light. However, this is not the only possibility. For example, the pixel may also include an N-type transistor, which can be turned on in response to a high-potential signal received at the gate, thereby controlling the first and second electrodes to conduct, and can be turned off in response to a low-potential signal received at the gate, thereby controlling the first and second electrodes to disconnect. Furthermore, Figure 4 In this embodiment, the pixel circuit P1 shared by the shared light-emitting element L1 and the privacy-protecting light-emitting element L1 can also be other structures, and this application does not limit this. The following embodiments all use... Figure 4 The structure shown is used as an example for illustration.

[0062] exist Figure 4 Based on this, further reference Figure 5 As can be seen, the embodiments of this application provide a scanning driving unit, which includes: a first shift circuit 01, a second shift circuit 02, and an output control circuit 03.

[0063] The first shift circuit 01 is connected to the first scanning terminal Scan1. The first shift circuit 01 is used to transmit the first scanning signal to the first scanning terminal Scan1.

[0064] For example, the first shift circuit 01 can be used to receive an input signal, shift the input signal to obtain a first scan signal, and transmit the first scan signal to the first scan terminal Scan1, or output it through the first scan terminal Scan1. The potential of the input signal can include both high and low potentials, and correspondingly, the potential of the output first scan signal also includes both high and low potentials.

[0065] The second shift circuit 02 is connected to the second scanning terminal Scan2. The second shift circuit 02 is used to transmit the second scan signal to the second scanning terminal Scan2.

[0066] For example, the second shift circuit 02 can be used to receive an input signal, shift the input signal to obtain a first scan signal, and transmit the first scan signal to the first scan terminal Scan1, or output it through the first scan terminal Scan1. The potential of the input signal can include both high and low potentials, and correspondingly, the potential of the output second scan signal also includes both high and low potentials.

[0067] Two output control circuits 03 are connected one-to-one to the shared light emission control terminal EM-shared and the privacy light emission control terminal EM-anti-peeping for the same pixel, and are also respectively connected to the first scan terminal Scan1, the second scan terminal Scan2, the first selection terminal IS1, the second selection terminal IS2, the first start terminal STV1, the second start terminal STV2, the first power terminal V1, and the second power terminal V2. Each output control circuit 03 is used to control the on / off state of each signal terminal in the first power terminal V1 and the second power terminal V2 with the corresponding connected shared light emission control terminal EM-shared or privacy light emission control terminal EM-anti-peeping in response to the first scan signal, the first start signal provided by the first start terminal STV1, the second scan signal, the second start signal provided by the second start terminal STV2, the first selection signal provided by the first selection terminal IS1, and the second selection signal provided by the second selection terminal IS2.

[0068] That is, reference Figure 5 ,against Figure 4 The shared light-emitting control terminal EM of the shared light-emitting element L1 is shown, and an output control circuit 03 is connected to it accordingly; for Figure 4 The privacy light control terminal EM of the privacy light-emitting element L1 shown is configured with another output control circuit 03 connected to it. In the figure, the terminal of each output control circuit 03 connected to either the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM is labeled as output control terminal OUT_EM. Thus, in this embodiment, the output control terminal OUT_EM of one output control circuit 03 can be connected to the shared light-emitting control terminal EM to provide the necessary shared light-emitting control signal, thereby driving the shared light-emitting element L1 to emit light. The output control terminal OUT_EM of the other output control circuit 03 can be connected to the privacy light-emitting control terminal EM to provide the necessary privacy light-emitting control signal, thereby driving the privacy light-emitting element L1 to emit light. The working principle of the two output control circuits 03 is similar.

[0069] For example, combining Figure 4 Given that transistor M8_1 is a P-type transistor, a low-potential shared light-emitting control signal can control the shared light-emitting element L1 in the pixel to emit light. Of course, if transistor M8_1 is an N-type transistor, a high-potential shared light-emitting control signal can control the shared light-emitting element L1 in the pixel to emit light. Similarly, given that transistor M8_2 is a P-type transistor, a low-potential privacy-prevention light-emitting control signal can control the privacy-prevention light-emitting element L1 in the pixel to emit light. Of course, if transistor M8_2 is an N-type transistor, a high-potential privacy-prevention light-emitting control signal can control the privacy-prevention light-emitting element L1 in the pixel to emit light.

[0070] Optionally, in the first power signal provided by the first power terminal V1 and the second power signal provided by the second power terminal V2, one power signal can have a high potential, and the other power signal can have a low potential. Furthermore, in this embodiment, the power terminal providing the high-potential power signal can also be referred to as the pull-up power terminal VGH, and the power terminal providing the low-potential power signal can also be referred to as the pull-down power terminal VGL. The following embodiments will not repeat the details. For example, in conjunction with... Figure 5 The first power supply terminal V1 shown is a pull-up power supply terminal VGH, providing a high-level first power supply signal. The second power supply terminal V2 shown is a pull-down power supply terminal VGL, providing a low-level second power supply signal. The potentials of the first selection signal provided by the first selection terminal IS1 and the second selection signal provided by the second selection terminal IS2 can both include high and low potentials. Furthermore, the first selection signal and the second selection signal can be inverse signals. That is, the potentials of the two selection signals can be exactly opposite at the same time. The potentials of the first start signal provided by the first start terminal STV1 and the second start signal provided by the second start terminal STV2 can both include high and low potentials. Furthermore, the first start signal and the second start signal can be inverse signals. That is, the potentials of the two start signals can be exactly opposite at the same time. Based on this, for example, combined with... Figure 5 It can be known that: by Figure 4 In the structure shown, taking the first power supply terminal V1 providing a high potential for the first power signal and the second power supply terminal V2 providing a low potential for the second power signal as an example: In the shared mode, the potential of the first scan signal provided by the first shift circuit 01 can be the first potential, or the potential of the second scan signal provided by the second shift circuit 02 can be the first potential; the potential of the first start signal can be the first potential, or the potential of the second start signal can be the first potential; and for the output control circuit 03 connected to the shared light emission control terminal EM, the potential of the first selection signal can be the second potential, and the potential of the second selection signal can be the first potential; for the output control circuit 03 connected to the privacy light emission control terminal EM, the potential of the first selection signal can be the first potential, and the potential of the second selection signal can be the second potential. Accordingly, the output control circuit 03 connected to the shared light emission control terminal EM can, under the control of the received signals, control the second power supply terminal V2 to be connected to the shared light emission control terminal EM and control the first power supply terminal V1 to be disconnected from the shared light emission control terminal EM, so that the low-potential second power signal provided by the second power supply terminal V2 can be transmitted to the shared light emission control terminal EM, and the high-potential first power signal provided by the first power supply terminal V1 will not be transmitted to the shared light emission control terminal EM. Therefore, it can be seen that at this time, the output control circuit 03 connected to the shared light emission control terminal EM can output a low-potential shared light emission control signal to the shared light emission control terminal EM, which can control, for example... Figure 4 Transistor M8_1 is turned on, driving the shared light-emitting element L1 to emit light. Simultaneously, the output control circuit 03 connected to the privacy light-emitting control terminal EM can, under the control of various received signals, control the first power supply terminal V1 to conduct with the privacy light-emitting control terminal EM and control the second power supply terminal V2 to disconnect from the privacy light-emitting control terminal EM. This allows the high-potential first power signal provided by the first power supply terminal V1 to be transmitted to the privacy light-emitting control terminal EM, while preventing the low-potential second power signal provided by the second power supply terminal V2 from being transmitted to the privacy light-emitting control terminal EM. Therefore, the output control circuit 03 connected to the privacy light-emitting control terminal EM can output a high-potential privacy light-emitting control signal to the privacy light-emitting control terminal EM, controlling the light emitted as follows: Figure 4 Transistor M8_2 is turned off, stopping the privacy light-emitting element L1 from emitting light. This ensures reliable shared display.

[0071] In privacy mode, the potential of the first scan signal provided by the first shift circuit 01 can be the first potential, or the potential of the second scan signal provided by the second shift circuit 02 can be the first potential; the potential of the first start signal can be the first potential, or the potential of the second start signal can be the first potential; and for the output control circuit 03 connected to the privacy light control terminal EM privacy, the potential of the first selection signal can be the second potential, and the potential of the second selection signal can be the first potential; for the output control circuit 03 connected to the shared light control terminal EM shared, the potential of the first selection signal can be the first potential, and the potential of the second selection signal can be the second potential. Accordingly, the output control circuit 03 connected to the privacy light control terminal EM privacy can, under the control of the received signals, control the second power supply terminal V2 to be connected to the privacy light control terminal EM privacy and control the first power supply terminal V1 to be disconnected from the privacy light control terminal EM privacy, so that the low-potential second power signal provided by the second power supply terminal V2 can be transmitted to the privacy light control terminal EM privacy, and so that the high-potential first power signal provided by the first power supply terminal V1 will not be transmitted to the privacy light control terminal EM privacy. Therefore, it can be seen that at this time, the output control circuit 03 connected to the EM anti-spy light control terminal can output a low-potential anti-spy light control signal to the EM anti-spy light control terminal, which can control such as Figure 4 Transistor M8_2 is turned on, driving the privacy light-emitting element L1 to emit light. Simultaneously, the output control circuit 03 connected to the shared light-emitting control terminal EM can, under the control of various received signals, control the first power supply terminal V1 to conduct with the shared light-emitting control terminal EM and control the second power supply terminal V2 to disconnect from the shared light-emitting control terminal EM. This allows the high-potential first power signal provided by the first power supply terminal V1 to be transmitted to the shared light-emitting control terminal EM, while preventing the low-potential second power signal provided by the second power supply terminal V2 from being transmitted to the shared light-emitting control terminal EM. Therefore, the output control circuit 03 connected to the shared light-emitting control terminal EM can output a high-potential shared light-emitting control signal to the shared light-emitting control terminal EM, controlling... Figure 4 Transistor M8_1 is turned off, stopping the shared light-emitting element L1 from emitting light. This ensures a reliable privacy display.

[0072] Optionally, as mentioned above, the first potential can refer to the effective potential, and the second potential can refer to the ineffective potential. For a P-type transistor, the effective potential can be a low potential, and the ineffective potential can be a high potential. For an N-type transistor, the effective potential can be a high potential, and the ineffective potential can be a low potential.

[0073] In summary, this application provides a scanning driving unit. Because the output control circuit in a single scanning driving unit can control the on / off state of the shared light-emitting control terminal and the privacy-protecting light-emitting control terminal connected to a pixel via different power supply terminals under the control of various signals such as the received scanning signal, start signal, and selection signal, the power supply signal can be flexibly set so that the single scanning driving unit simultaneously provides shared light-emitting control signals and privacy-protecting light-emitting control signals of different potentials to the shared light-emitting control terminal and the privacy-protecting light-emitting control terminal. That is, the privacy-protecting display mode and the shared display mode can be flexibly switched through the same pixel circuit. Thus, it does not limit the development of display panels towards higher resolution, and can simultaneously achieve high-resolution display with privacy-protecting and shared switching functions.

[0074] Optionally, in Figure 5 On this basis, Figure 6 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 6 It can be seen that each output control circuit 03 may include: a first control sub-circuit 031 and a second control sub-circuit 032.

[0075] The first control sub-circuit 031 can be connected to the first scan terminal Scan1, the first start terminal STV1, the first selection terminal IS1, the second selection terminal IS2, the first power supply terminal V1, the second power supply terminal V2, and the first output terminal OUT1, respectively. The first control sub-circuit 031 can be used to control the on / off state of each signal terminal of the first power supply terminal V1 and the second power supply terminal V2 with the first output terminal OUT1 in response to the first scan signal, the first start signal, the first selection signal, and the second selection signal.

[0076] For example, the first control sub-circuit 031 can, for example, control the first power supply terminal V1 to be connected to the first output terminal OUT1 and control the second power supply terminal V2 to be disconnected from the first output terminal OUT1 when, for example, the potential of the first scan signal is the first potential, the potential of the first start signal is the first potential, the potential of the first selection signal is the first potential, and the potential of the second selection signal is the second potential. This allows the first power signal provided by the first power supply terminal V1 to be transmitted to the first output terminal OUT1 and output through the first output terminal OUT1, while preventing the second power signal provided by the second power supply terminal V2 from being transmitted to the first output terminal OUT1. The first control sub-circuit 031 can, for example, control the second power supply terminal V2 to be connected to the first output terminal OUT1 and control the first power supply terminal V1 to be disconnected from the first output terminal OUT1 when, for example, the potential of the first scan signal is the first potential, the potential of the first start signal is the first potential, the potential of the second selection signal is the first potential, and the potential of the first selection signal is the second potential. This allows the second power signal provided by the second power supply terminal V2 to be transmitted to the first output terminal OUT1 and output through the first output terminal OUT1, while preventing the first power signal provided by the first power supply terminal V1 from being transmitted to the first output terminal OUT1. In this way, a high-potential signal or a low-potential signal can be output through the first output terminal OUT1.

[0077] The second control sub-circuit 032 can be connected to the second scan terminal Scan2, the second start terminal STV2, the first selection terminal IS1, the second selection terminal IS2, the first power supply terminal V1, the second power supply terminal V2, and the second output terminal OUT2, respectively. The second control sub-circuit 032 can be used to control the on / off state of each signal terminal of the first power supply terminal V1 and the second power supply terminal V2 with the second output terminal OUT2 in response to the second scan signal, the second start signal, the first selection signal, and the second selection signal.

[0078] For example, similar to the first control sub-circuit 031, the second control sub-circuit 032 can, for example, control the first power supply terminal V1 to conduct with the second output terminal OUT2 when the potential of the second scan signal is the first potential, the potential of the second start signal is the first potential, the potential of the first selection signal is the first potential, and the potential of the second selection signal is the second potential. This control allows the first power signal provided by the first power supply terminal V1 to be transmitted to the second output terminal OUT2 and output through the second output terminal OUT2, while preventing the second power signal provided by the second power supply terminal V2 from being transmitted to the second output terminal OUT2. The second control sub-circuit 032 can, for example, control the second power supply terminal V2 to conduct with the second output terminal OUT2 when the potential of the second scan signal, the potential of the second start signal, the potential of the second selection signal, and the potential of the first selection signal are all at the first potential, and the potential of the first selection signal is at the second potential. Simultaneously, it controls the first power supply terminal V1 to disconnect from the second output terminal OUT2. This allows the second power signal provided by the second power supply terminal V2 to be transmitted to the second output terminal OUT2 and output through it, while preventing the first power signal provided by the first power supply terminal V1 from being transmitted to the second output terminal OUT2. In this way, a high-potential signal or a low-potential signal is output through the second output terminal OUT2.

[0079] Furthermore, both the first output terminal OUT1 and the second output terminal OUT2 can be connected to the corresponding shared light control terminal EM or the privacy light control terminal EM. This can include direct or indirect connections. For example, Figure 6 In one embodiment, the first output terminal OUT1 and the second output terminal OUT2 of each output control circuit 03 are directly connected to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the same output control terminal OUT_EM.

[0080] That is, in this embodiment, each output control circuit 03 can be divided into two control sub-circuits. One control sub-circuit, under the control of the first scan signal and the first start signal, and in conjunction with the first selection signal and the second selection signal, controls the on / off state of each signal terminal of the first power supply terminal V1 and the second power supply terminal V2 with the first output terminal OUT1. The other control sub-circuit, under the control of the second scan signal and the second start signal, and in conjunction with the first selection signal and the second selection signal, controls the on / off state of each signal terminal of the first power supply terminal V1 and the second power supply terminal V2 with the second output terminal OUT2. This allows for the output of a high-potential first power signal or a low-potential second power signal to the first output terminal OUT1 and the second output terminal OUT2, respectively.

[0081] Optionally, in Figure 6 On this basis, Figure 7This schematic diagram illustrates the structure of yet another scanning drive unit. (Reference) Figure 7 It can be seen that, for each output control circuit 03, the first control sub-circuit 031 may include: a first control unit 0311 and a second control unit 0312.

[0082] The first control unit 0311 can be connected to one of the following power terminals: the first scan terminal Scan1, the first selection terminal IS1, the first start terminal STV1, the first output terminal OUT1, the first power supply terminal V1, and the second power supply terminal V2. The first control unit 0311 can be used to control the on / off state of the power supply terminal and the first output terminal OUT1 in response to the first scan signal, the first selection signal, and the first start signal.

[0083] Optionally, refer to Figure 7 The first control unit 0311 shown can be connected to a first power supply terminal V1, for example. That is, the first power supply terminal to which the first control unit 0311 is connected can be the first power supply terminal V1. Of course, the first power supply terminal to which the first control unit 0311 is connected can also be a second power supply terminal V2.

[0084] For example, taking the first control unit 0311 connected to the first power supply terminal V1 as an example, combined with... Figure 7 The first control unit 0311 can, when both the potential of the first scan signal and the potential of the first start signal are at the first potential, control the first power supply terminal V1 to be connected to the first output terminal OUT1 when the potential of the first selection signal is at the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the first output terminal OUT1 and output through the first output terminal OUT1; and when the potential of the first selection signal is at the second potential, control the first power supply terminal V1 to be disconnected from the first output terminal OUT1, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the first output terminal OUT1. The control principle of the first control unit 0311 connecting to the second power supply terminal V2 is the same and will not be repeated.

[0085] The second control unit 0312 can be connected to another power supply terminal among the first scan terminal Scan1, the second selection terminal IS2, the first start terminal STV1, the first output terminal OUT1, the first power supply terminal V1, and the second power supply terminal V2. The second control unit 0312 can be used to control the connection and disconnection between the other power supply terminal and the first output terminal OUT1 in response to the first scan signal, the second selection signal, and the first start signal.

[0086] Optionally, refer to Figure 7The second control unit 0312 shown can be connected to a second power supply terminal V2, for example. That is, the other power supply terminal to which the second control unit 0312 is connected can be the second power supply terminal V2. Of course, the other power supply terminal to which the second control unit 0312 is connected can also be the first power supply terminal V1. It is only necessary to satisfy that the first control unit 0311 and the second control unit 0312 are connected to the first power supply terminal V1 and the second power supply terminal V2 respectively.

[0087] For example, taking the second control unit 0312 connected to the second power supply terminal V2 as an example, combined with... Figure 7 The second control unit 0312 can, when the potentials of the first scan signal and the first start signal are both at the first potential, control the second power supply terminal V2 to conduct with the first output terminal OUT1 when the potential of the second selection signal is at the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the first output terminal OUT1 and output through the first output terminal OUT1; and when the potential of the second selection signal is at the second potential, control the second power supply terminal V2 to disconnect from the first output terminal OUT1, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the first output terminal OUT1. The control principle of the second control unit 0312 connecting to the first power supply terminal V1 is the same and will not be repeated.

[0088] That is, in this embodiment, each first control sub-circuit 031 can be divided into two control units. One control unit, under the control of the first scan signal and the first start signal, and in conjunction with the first selection signal, controls the connection and disconnection between one of the power terminals (e.g., the first power terminal V1) of the first power terminal V1 and the second power terminal V2 and the first output terminal OUT1. The other control unit, under the control of the first scan signal and the first start signal, and in conjunction with the second selection signal, controls the connection and disconnection between the other power terminal (e.g., the second power terminal V2) of the first power terminal V1 and the first output terminal OUT1. This allows for the output of a high-potential first power signal or a low-potential second power signal to the first output terminal OUT1, respectively.

[0089] Optionally, in Figure 7 On this basis, Figure 8 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 8 It can be seen that, for each output control circuit 03, the second control sub-circuit 032 may include, as with the first control sub-circuit 031, a third control unit 0321 and a fourth control unit 0322.

[0090] The third control unit 0321 can be connected to one of the following power terminals: the second scan terminal Scan2, the first selection terminal IS1, the second start terminal STV2, the second output terminal OUT2, the first power terminal V1, and the second power terminal V2. The third control unit 0321 can be used to control the on / off state of the power terminal and the second output terminal OUT2 in response to the second scan signal, the first selection signal, and the second start signal.

[0091] Optionally, refer to Figure 8 The third control unit 0321 shown can be connected to the first power supply terminal V1, for example. That is, one power supply terminal to which the third control unit 0321 is connected can be the first power supply terminal V1. Of course, one power supply terminal to which the third control unit 0321 is connected can also be the second power supply terminal V2.

[0092] For example, taking the third control unit 0321 connected to the first power supply terminal V1 as an example, combined with... Figure 8 The third control unit 0321 can, when both the potential of the second scan signal and the potential of the second start signal are at the first potential, control the first power supply terminal V1 to be connected to the second output terminal OUT2 when the potential of the first selection signal is at the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the second output terminal OUT2 and output through the second output terminal OUT2; and when the potential of the first selection signal is at the second potential, control the first power supply terminal V1 to be disconnected from the second output terminal OUT2, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the second output terminal OUT2. The control principle of the third control unit 0321 connecting to the second power supply terminal V2 is the same and will not be repeated.

[0093] The fourth control unit 0322 can be connected to another power supply terminal among the second scan terminal Scan2, the second selection terminal IS2, the second start terminal STV2, the second output terminal OUT2, the first power supply terminal V1, and the second power supply terminal V2. The fourth control unit 0322 can be used to control the on / off state of the other power supply terminal and the second output terminal OUT2 in response to the second scan signal, the second selection signal, and the second start signal.

[0094] Optionally, refer to Figure 8 The fourth control unit 0322 shown can be connected to the second power supply terminal V2, for example. That is, the other power supply terminal to which the fourth control unit 0322 is connected can be the second power supply terminal V2. Of course, the other power supply terminal to which the fourth control unit 0322 is connected can also be the first power supply terminal V1. It is only necessary that the third control unit 0321 and the fourth control unit 0322 are connected to the first power supply terminal V1 and the second power supply terminal V2, respectively.

[0095] For example, taking the fourth control unit 0322 connected to the second power supply terminal V2 as an example, combined with... Figure 8 The fourth control unit 0322 can, when both the potential of the second scan signal and the potential of the second start signal are at the first potential, control the second power supply terminal V2 to be connected to the second output terminal OUT2 when the potential of the second selection signal is at the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the second output terminal OUT2 and output through the second output terminal OUT2; and when the potential of the second selection signal is at the second potential, control the second power supply terminal V2 to be disconnected from the second output terminal OUT2, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the second output terminal OUT2. The control principle of the fourth control unit 0322 connecting to the first power supply terminal V1 is the same, and will not be repeated.

[0096] That is, in this embodiment of the application, similar to the first control sub-circuit 031, each second control sub-circuit 032 can also be divided into two control units. One control unit is configured to control, under the control of the second scan signal and the second start signal, and in conjunction with the first selection signal, control the connection and disconnection of one of the power terminals (e.g., the first power terminal V1) and the second output terminal OUT2 between the first power terminal V1 and the second power terminal V2. The other control unit is configured to control, under the control of the second scan signal and the second start signal, and in conjunction with the second selection signal, control the connection and disconnection of the other power terminal (e.g., the second power terminal V2) between the first power terminal V1 and the second power terminal V2 between the second output terminal OUT2. This allows for the output of a high-level first power signal or a low-level second power signal to the second output terminal OUT2, respectively.

[0097] Optionally, in Figure 8 On this basis, Figure 9 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 9 It can be seen that the first control unit 0311 may include: a first control subunit 03111 and a second control subunit 03112.

[0098] The first control subunit 03111 can be connected to the first scan terminal Scan1, the first selection terminal IS1, a power supply terminal, and the first node N1, respectively. The first control subunit 03111 can be used to control the on / off state of the first selection terminal IS1 and the first node N1 in response to the first scan signal, and to regulate the potential of the first node N1 based on the power supply signal provided by the power supply terminal.

[0099] For example, taking the first power supply terminal V1 connected to the first control subunit 03111 as an example, the first control subunit 03111 can control the first selection terminal IS1 to conduct with the first node N1 when the potential of the first scan signal is the first potential, so that the first selection signal provided by the first selection terminal IS1 can be transmitted to the first node N1, and the potential of the first node N1 can be controlled to be the potential of the first selection signal. Furthermore, the first control subunit 03111 can also adjust and control the potential of the first node N1 based on the first power signal provided by the first power supply terminal V1, to achieve, for example, stable storage of the potential of the first node N1. The control principle of the first control subunit 03111 connected to the second power supply terminal V2 is similar and will not be repeated.

[0100] The second control subunit 03112 can be connected to the first node N1, the first start terminal STV1, a power supply terminal, and the first output terminal OUT1, respectively. The second control subunit 03112 can be used to control the on / off state of the power supply terminal and the first output terminal OUT1 in response to the potential of the first node N1 and the first start signal.

[0101] For example, taking the first power supply terminal V1 connected to the second control subunit 03112 as an example, the second control subunit 03112 can control the first power supply terminal V1 to conduct with the first output terminal OUT1 when the potential of the first node N1 and the potential of the first start signal are both at the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the first output terminal OUT1. The second control subunit 03112 can also control the first power supply terminal V1 to disconnect from the first output terminal OUT1 when the potential of the first node N1 and / or the potential of the first start signal are at the second potential, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the first output terminal OUT1. The control principle of the second control subunit 03112 connected to the second power supply terminal V2 is the same, and will not be repeated.

[0102] That is, in this embodiment, each first control unit 0311 can be divided into two control subunits, and one control subunit is configured to control the potential of the first node N1; the other control subunit is configured to control the connection and disconnection of a connected power supply terminal and the first output terminal OUT1 under the control of the potential of the first node N1 and the first start signal. This outputs a power signal provided by the power supply terminal, such as a high-potential first power signal provided by the first power supply terminal V1, to the first output terminal OUT1.

[0103] Optionally, in Figure 9 On this basis, Figure 10 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 10It can be seen that the second control unit 0312 may include: a third control subunit 03121 and a fourth control subunit 03122.

[0104] The third control subunit 03121 can be connected to the first scan terminal Scan1, the second selection terminal IS2, another power supply terminal, and the fourth node N4, respectively. The third control subunit 03121 can be used to control the on / off state of the second selection terminal IS2 and the fourth node N4 in response to the first scan signal, and to regulate the potential of the fourth node N4 based on the power signal provided by the other power supply terminal.

[0105] For example, taking the second power supply terminal V2 as the other power supply terminal connected to the third control subunit 03121, the third control subunit 03121 can control the second selection terminal IS2 to conduct with the fourth node N4 when the potential of the first scan signal is the first potential. This allows the second selection signal provided by the second selection terminal IS2 to be transmitted to the fourth node N4, controlling the potential of the fourth node N4 to be the potential of the second selection signal. Furthermore, the third control subunit 03121 can also adjust the potential of the fourth node N4 based on the second power signal provided by the second power supply terminal V2 to achieve, for example, stable storage of the potential of the fourth node N4. The control principle of the third control subunit 03121 connected to the first power supply terminal V1 is similar and will not be repeated.

[0106] The fourth control subunit 03122 can be connected to the fourth node N4, the first start terminal STV1, another power supply terminal, and the first output terminal OUT1, respectively. The fourth control subunit 03122 can be used to control the on / off state of the other power supply terminal and the first output terminal OUT1 in response to the potential of the fourth node N4 and the first start signal.

[0107] For example, taking the second power supply terminal V2 connected to the fourth control subunit 03122 as an example, the fourth control subunit 03122 can control the second power supply terminal V2 to conduct with the first output terminal OUT1 when the potential of the fourth node N4 and the potential of the first start signal are both the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the first output terminal OUT1. The fourth control subunit 03122 can also control the second power supply terminal V2 to disconnect from the first output terminal OUT1 when the potential of the fourth node N1 and / or the potential of the first start signal are the second potential, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the first output terminal OUT1. The control principle of the fourth control subunit 03122 connected to the first power supply terminal V1 is similar and will not be repeated.

[0108] That is, in this embodiment of the application, similar to the first control unit 0311, each second control unit 0312 can also be divided into two control subunits, and one control subunit is configured to control the potential of the fourth node N4; the other control subunit is configured to control the connection and disconnection between the other power supply terminal and the first output terminal OUT1 under the control of the potential of the fourth node N4 and the first start signal. This allows the power signal provided by the other power supply terminal, such as a low-potential second power signal provided by the second power supply terminal V2, to be output to the first output terminal OUT1.

[0109] Optionally, in Figure 10 On this basis, Figure 11 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 11 It can be seen that the third control unit 0321 may include: the fifth control subunit 03211 and the sixth control subunit 03212.

[0110] The fifth control subunit 03211 can be connected to the second scan terminal Scan2, the first selection terminal IS1, a power supply terminal, and the seventh node N7, respectively. The fifth control subunit 03211 can be used to control the on / off state of the first selection terminal IS1 and the seventh node N7 in response to the second scan signal, and to regulate the potential of the seventh node N7 based on the power supply signal provided by the power supply terminal.

[0111] For example, taking the power supply terminal connected to the fifth control subunit 03211 as the first power supply terminal V1, the fifth control subunit 03211 can control the first selection terminal IS1 to conduct with the seventh node N7 when the potential of the second scan signal is the first potential. This allows the first selection signal provided by the first selection terminal IS1 to be transmitted to the seventh node N7, controlling the potential of the seventh node N7 to be the potential of the first selection signal. Furthermore, the fifth control subunit 03211 can also adjust the potential of the seventh node N7 based on the first power signal provided by the first power supply terminal V1 to achieve, for example, stable storage of the potential of the seventh node N7. The control principle of the fifth control subunit 03211 connected to the second power supply terminal V2 is similar and will not be repeated.

[0112] The sixth control subunit 03212 can be connected to the seventh node N7, the second start terminal STV2, a power supply terminal, and the second output terminal OUT2, respectively. The sixth control subunit 03212 can be used to control the on / off state of the power supply terminal and the second output terminal OUT2 in response to the potential of the seventh node N7 and the second start signal.

[0113] For example, taking the power supply terminal connected to the sixth control subunit 03212 as the first power supply terminal V1, the sixth control subunit 03212 can control the first power supply terminal V1 to conduct with the second output terminal OUT2 when the potential of the seventh node N7 and the potential of the second start signal are both the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the second output terminal OUT2. The sixth control subunit 03212 can also control the first power supply terminal V1 to disconnect from the second output terminal OUT2 when the potential of the seventh node N7 and / or the potential of the second start signal are the second potential, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the second output terminal OUT2. The control principle of the sixth control subunit 03212 connected to the second power supply terminal V2 is similar and will not be repeated.

[0114] That is, in this embodiment of the application, similar to the first control unit 0311, each third control unit 0321 can also be divided into two control subunits, and one control subunit is configured to control the potential of the seventh node N7; the other control subunit is configured to control the connection and disconnection of a connected power supply terminal and the second output terminal OUT2 under the control of the potential of the seventh node N7 and the second start signal. This outputs a power signal provided by the power supply terminal, such as a high-potential first power signal provided by the first power supply terminal V1, to the second output terminal OUT2.

[0115] Optionally, in Figure 11 On this basis, Figure 12 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 12 It can be seen that the fourth control unit 0322 may include: the seventh control subunit 03221 and the eighth control subunit 03222.

[0116] The seventh control subunit 03221 can be connected to the second scan terminal Scan2, the second selection terminal IS2, another power supply terminal, and the tenth node N10, respectively. The seventh control subunit 03221 can be used to control the on / off state of the second selection terminal IS2 and the tenth node N10 in response to the second scan signal, and to regulate the potential of the tenth node N10 based on the power signal provided by the other power supply terminal.

[0117] For example, taking the second power supply terminal V2 connected to the seventh control subunit 03221 as an example, the seventh control subunit 03221 can control the second selection terminal IS2 to conduct with the tenth node N10 when the potential of the second scan signal is the first potential. This allows the second selection signal provided by the second selection terminal IS2 to be transmitted to the tenth node N10, controlling the potential of the tenth node N10 to be the potential of the second selection signal. Furthermore, the seventh control subunit 03221 can also adjust the potential of the tenth node N10 based on the second power signal provided by the second power supply terminal V2 to achieve, for example, stable storage of the potential of the tenth node N10. The control principle of the seventh control subunit 03221 connected to the first power supply terminal V1 is similar and will not be repeated.

[0118] The eighth control subunit 03222 can be connected to the tenth node N10, the second start terminal STV2, another power supply terminal, and the second output terminal OUT2, respectively. The eighth control subunit 03222 can be used to control the on / off state of the other power supply terminal and the second output terminal OUT2 in response to the potential of the tenth node N10 and the second start signal.

[0119] For example, taking the second power supply terminal V2 connected to the eighth control subunit 03222 as an example, the eighth control subunit 03222 can control the second power supply terminal V2 to conduct with the second output terminal OUT2 when the potential of the tenth node N10 and the potential of the second start signal are both the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the second output terminal OUT2. The eighth control subunit 03222 can also control the second power supply terminal V2 to disconnect from the second output terminal OUT2 when the potential of the tenth node N10 and / or the potential of the second start signal are the second potential, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the second output terminal OUT2. The control principle of the eighth control subunit 03222 connected to the first power supply terminal V1 is the same and will not be repeated.

[0120] That is, in this embodiment of the application, similar to the first control unit 0311, each fourth control unit 0322 can also be divided into two control subunits, and one control subunit is configured to control the potential of the tenth node N10; the other control subunit is configured to control the connection and disconnection of the other power supply terminal and the second output terminal OUT2 under the control of the potential of the tenth node N10 and the second start signal. This outputs a power signal provided by the other power supply terminal, such as a low-potential second power signal provided by the second power supply terminal V2, to the second output terminal OUT2.

[0121] Optionally, in Figure 12 On this basis, Figure 13 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 13It can be seen that the first control subunit 03111 may include: a first control unit B1 and a second control unit B2.

[0122] The first control unit B1 can be connected to the first scan terminal Scan1, the first selection terminal IS1, and the first node N1 respectively. The first control unit B1 can be used to control the on / off state of the first selection terminal IS1 and the first node N1 in response to the first scan signal.

[0123] For example, the first control unit B1 can control the first selection terminal IS1 to be connected to the first node N1 when the potential of the first scan signal is a first potential, so that the first selection signal provided by the first selection terminal IS1 can be transmitted to the first node N1. The first control unit B1 can also control the first selection terminal IS1 to be disconnected from the first node N1 when the potential of the first scan signal is a second potential, so that the first selection signal provided by the first selection terminal IS1 cannot be transmitted to the first node N1.

[0124] The second control unit B2 can be connected to a power supply terminal and the first node N1 respectively. The second control unit B2 can be used to regulate the potential of the first node N1 based on the power signal provided by the power supply terminal.

[0125] Optionally, refer to Figure 13 In the scan drive unit shown, the second control unit B2 is connected to a power supply terminal that is the first power supply terminal V1. Of course, it is not limited to this.

[0126] For example, taking the second control unit B2 connected to the first power supply terminal V1 as an example, the second control unit B2 can be used to adjust and control the potential of the first node N1 based on the first power signal provided by the first power supply terminal V1 through coupling. The control principle of the second control unit B2 connected to the second power supply terminal V2 is the same and will not be repeated.

[0127] The coupling effect can refer to the following: utilizing the physical property of a capacitor to block DC and pass AC, when the potential on one plate of a capacitor changes, the changing electric field induces a corresponding charge on the other plate of the capacitor, causing a change in the potential at the other end, thus achieving signal coupling and transmission. In this way, by setting the second control unit B2 to further regulate the potential of the first node N1 based on power signal coupling, the reliability of controlling the potential of the first node N1 can be further improved, making the potential of the first node N1 more stable. The effects of the coupling effect described below are similar and will not be repeated.

[0128] That is, in the embodiments of this application, the first control subunit 03111 can be divided into two control units to reliably control the potential of the first node N1 through switch control and coupling control.

[0129] Optionally, in Figure 13On this basis, Figures 14 to 16 The schematic diagram illustrates the structure of various scan drive units. (Reference) Figures 14 to 16 It can be seen that the second control subunit 03112 may include: a third control unit B3, and may also include at least one of the following control units: a fourth control unit B4 and a fifth control unit B5.

[0130] The third control unit B3 can be connected to the first node N1, the second node N2, and the third node N3 respectively. The third control unit B3 can be used to control the on / off state of the second node N2 and the third node N3 in response to the potential of the first node N1.

[0131] For example, the third control unit B3 can control the second node N2 and the third node N3 to be connected when the potential of the first node N1 is at the first potential, so that the signals between the second node N2 and the third node N3 can be transmitted back and forth. The third control unit B3 can also control the second node N2 and the third node N3 to be disconnected when the potential of the first node N1 is at the second potential, so that the signals between the second node N2 and the third node N3 cannot be transmitted back and forth.

[0132] The fourth control unit B4 can be connected between the second node N2 and a power supply terminal, and can also be connected to the first start terminal STV1. The fourth control unit B4 can be used to control the on / off state of a power supply terminal and the second node N2 in response to the first start signal.

[0133] Optionally, refer to Figure 14 and Figure 16 In the scan drive unit shown, the fourth control unit B4 is connected to a power supply terminal that is the first power supply terminal V1. Of course, it is not limited to this.

[0134] For example, taking the fourth control unit B4 connected to the first power supply terminal V1 as an example, the fourth control unit B4 can control the first power supply terminal V1 to conduct with the second node N2 when the potential of the first start signal is the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the second node N2. The fourth control unit B4 can also control the first power supply terminal V1 to disconnect from the second node N2 when the potential of the first start signal is the second potential, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the second node N2. The control principle of the fourth control unit B4 connected to the second power supply terminal V2 is similar and will not be repeated.

[0135] The fifth control unit B5 can be connected between the third node N3 and the first output terminal OUT1, and can also be connected to the first start terminal STV1. The fifth control unit B5 can be used to control the on / off state of the third node N3 and the first output terminal OUT1 in response to the first start signal.

[0136] For example, the fifth control unit B5 can control the third node N3 to be connected to the first output terminal OUT1 when the potential of the first start signal is the first potential, so that the signal transmitted to the third node N3 can be further transmitted to the first output terminal OUT1 and output through the first output terminal OUT1. The fifth control unit B5 can also control the third node N3 to be disconnected from the first output terminal OUT1 when the potential of the first start signal is the second potential, so that the signal transmitted to the third node N3 cannot be further transmitted to the first output terminal OUT1.

[0137] That is, in one embodiment, such as Figure 14 As shown, the second control subunit 03112 may include a third control unit B3 and a fourth control unit B4. In this structure, the third node N3 can be directly connected to the first output terminal OUT1. Alternatively, it can be understood that the second control subunit 03112 can be divided into two control units. One control unit is connected between the first power supply terminal V1 and the second node N2 to control the connection and disconnection between the first power supply terminal V1 and the second node N2. The other control unit is connected between the second node N2 and the third node N3 to control the connection and disconnection between the second node N2 and the third node N3. Since the third node N3 is directly connected to the first output terminal OUT1, it can also be understood as controlling the connection and disconnection between the second node N2 and the first output terminal OUT1.

[0138] Alternatively, in another embodiment, such as Figure 15 As shown, the second control subunit 03112 may include a third control unit B3 and a fifth control unit B5. In this structure, the second node N2 can be directly connected to a power supply terminal (e.g., the first power supply terminal V1). Alternatively, it can be understood that the second control subunit 03112 can be divided into two control units, with one control unit connected between the second node N2 and the third node N3 to control the on / off state of the second node N2 and the third node N3. Since the second node N2 is directly connected to the first power supply terminal V1, it can also be understood as controlling the on / off state of the first power supply terminal V1 and the third node N3. The other control unit is connected between the third node N3 and the first output terminal OUT1 to control the on / off state of the third node N3 and the first output terminal OUT1.

[0139] Alternatively, in yet another embodiment, such as Figure 16As shown, the second control subunit 03112 may include a third control unit B3, a fourth control unit B4, and a fifth control unit B5. Alternatively, it can be understood that the second control subunit 03112 can be divided into three control units: one control unit is connected between the first power supply terminal V1 and the second node N2, controlling the connection and disconnection between the first power supply terminal V1 and the second node N2; another control unit is connected between the second node N2 and the third node N3, controlling the connection and disconnection between the second node N2 and the third node N3; and yet another control unit is connected between the third node N3 and the first output terminal OUT1, controlling the connection and disconnection between the third node N3 and the first output terminal OUT1.

[0140] In other words, if a control unit is set between the second node N2 and the third node N3, a control unit can also be set between the first power supply terminal V1 and the second node N2, and / or between the third node N3 and the first output terminal OUT1. Setting more control units can improve control reliability.

[0141] Optionally, in Figure 16 On this basis, Figure 17 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 17 It can be seen that the third control subunit 03121 may include: the sixth control unit B6 and the seventh control unit B7.

[0142] The sixth control unit B6 can be connected to the first scan terminal Scan1, the second selection terminal IS2, and the fourth node N4, respectively. The sixth control unit B6 can be used to control the on / off state of the second selection terminal IS2 and the fourth node N4 in response to the first scan signal.

[0143] For example, the sixth control unit B6 can control the second selection terminal IS2 to be connected to the fourth node N4 when the potential of the first scan signal is the first potential, so that the second selection signal provided by the second selection terminal IS2 can be transmitted to the fourth node N4. The sixth control unit B6 can also control the second selection terminal IS2 to be disconnected from the fourth node N4 when the potential of the first scan signal is the second potential, so that the second selection signal provided by the second selection terminal IS2 cannot be transmitted to the fourth node N4.

[0144] The seventh control unit B7 can be connected to another power supply terminal and the fourth node N4 respectively. The seventh control unit B7 can be used to regulate the potential of the fourth node N4 based on the power signal provided by the other power supply terminal.

[0145] Optionally, refer to Figure 17 In the scan drive unit shown, the seventh control unit B7 is connected to a second power supply terminal V2. However, this is not the only possibility.

[0146] For example, taking the seventh control unit B7 connected to the second power supply terminal V2 as an example, the seventh control unit B7 can be used to adjust and control the potential of the fourth node N4 based on the second power supply signal provided by the second power supply terminal V2 through coupling. The control principle of the seventh control unit B7 connected to the first power supply terminal V1 is similar and will not be repeated.

[0147] That is, in the embodiments of this application, the third control subunit 03121 can be divided into two control units to reliably control the potential of the fourth node N4 through switch control and coupling control.

[0148] Optionally, in Figure 17 On this basis, Figures 18 to 20 The schematic diagram illustrates the structure of various scan drive units. (Reference) Figures 18 to 20 It can be seen that the fourth control subunit 03122 may include: the eighth control unit B8, and may also include at least one of the following control units: the ninth control unit B9, and the tenth control unit B10.

[0149] The eighth control unit B8 can be connected to the fourth node N4, the fifth node N5 and the sixth node N6 respectively. The eighth control unit B8 can be used to control the on / off state of the fifth node N5 and the sixth node N6 in response to the potential of the fourth node N4.

[0150] For example, the eighth control unit B8 can control the fifth node N5 and the sixth node N6 to be connected when the potential of the fourth node N4 is at the first potential, so that the signals between the fifth node N5 and the sixth node N6 can be transmitted back and forth. The eighth control unit B8 can also control the fifth node N5 and the sixth node N6 to be disconnected when the potential of the fourth node N4 is at the second potential, so that the signals between the fifth node N5 and the sixth node N6 cannot be transmitted back and forth.

[0151] The ninth control unit B9 can be connected between the fifth node N5 and another power supply terminal, and can also be connected to the first start terminal STV1. The ninth control unit B9 can be used to control the on / off state of the other power supply terminal and the fifth node N5 in response to the first start signal.

[0152] Optionally, refer to Figure 18 and Figure 20 In the scan drive unit shown, the ninth control unit B9 is connected to a second power supply terminal V2. However, this is not the only possibility.

[0153] For example, taking the ninth control unit B9 connected to the second power supply terminal V2 as an example, the ninth control unit B9 can control the second power supply terminal V2 to conduct with the fifth node N5 when the potential of the first start signal is the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the fifth node N5. The ninth control unit B9 can also control the second power supply terminal V2 to disconnect from the fifth node N5 when the potential of the first start signal is the second potential, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the fifth node N5. The control principle of the ninth control unit B9 connected to the first power supply terminal V1 is similar and will not be repeated.

[0154] The tenth control unit B10 can be connected between the sixth node N6 and the first output terminal OUT1, and is also connected to the first start terminal STV1. The tenth control unit B10 can be used to control the on / off state of the sixth node N6 and the first output terminal OUT1 in response to the first start signal.

[0155] For example, the tenth control unit B10 can control the sixth node N6 to be connected to the first output terminal OUT1 when the potential of the first start signal is the first potential, so that the signal transmitted to the sixth node N6 can be further transmitted to the first output terminal OUT1 and output through the first output terminal OUT1. The tenth control unit B10 can also control the sixth node N6 to be disconnected from the first output terminal OUT1 when the potential of the first start signal is the second potential, so that the signal transmitted to the sixth node N6 cannot be further transmitted to the first output terminal OUT1.

[0156] That is, in one embodiment, such as Figure 18 As shown, the third control subunit 03122 may include an eighth control unit B8 and a ninth control unit B9. In this structure, the sixth node N6 can be directly connected to the first output terminal OUT1. Alternatively, it can be understood that the third control subunit 03122 can be divided into two control units. One control unit is connected between the second power supply terminal V2 and the fifth node N5 to control the connection between the second power supply terminal V2 and the fifth node N5. The other control unit is connected between the fifth node N5 and the sixth node N6 to control the connection between the fifth node N5 and the sixth node N6. Since the sixth node N6 is directly connected to the first output terminal OUT1, it can also be understood as controlling the connection between the fifth node N5 and the first output terminal OUT1.

[0157] Alternatively, in another embodiment, such as Figure 19As shown, the third control subunit 03122 may include an eighth control unit B8 and a tenth control unit B10. In this structure, the fifth node N5 can be directly connected to a power supply terminal (e.g., the second power supply terminal V2). Alternatively, it can be understood that the third control subunit 03122 can be divided into two control units, with one control unit connected between the fifth node N5 and the sixth node N6 to control the on / off state of the fifth node N5 and the sixth node N6. Since the fifth node N5 is directly connected to the second power supply terminal V2, it can also be understood as controlling the on / off state of the second power supply terminal V2 and the fifth node N5. The other control unit is connected between the sixth node N6 and the first output terminal OUT1 to control the on / off state of the sixth node N6 and the first output terminal OUT1.

[0158] Alternatively, in yet another embodiment, such as Figure 20 As shown, the third control subunit 03122 may include an eighth control unit B8, a ninth control unit B9, and a tenth control unit B10. Alternatively, it can be understood that the third control subunit 03122 can be divided into three control units, with one control unit connected between the second power supply terminal V2 and the fifth node N5 to control the on / off state of the second power supply terminal V2 and the fifth node N5; another control unit connected between the fifth node N5 and the sixth node N6 to control the on / off state of the fifth node N5 and the sixth node N6; and yet another control unit connected between the sixth node N6 and the first output terminal OUT1 to control the on / off state of the sixth node N6 and the first output terminal OUT1.

[0159] In other words, if a control unit is set between the fifth node N5 and the sixth node N6, it is also possible to set a control unit between the second power supply terminal V2 and the fifth node N5, and / or, it is also possible to set a control unit between the sixth node N6 and the first output terminal OUT1. By setting more control units, control reliability can be improved.

[0160] Optionally, in Figure 20 On this basis, Figure 21 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 21 It can be seen that the fifth control subunit 03211 may include: the eleventh control unit B11 and the twelfth control unit B12.

[0161] The eleventh control unit B11 can be connected to the second scan terminal Scan2, the first selection terminal IS1, and the seventh node N7, respectively. The eleventh control unit B11 can be used to control the on / off state of the first selection terminal IS1 and the seventh node N7 in response to the second scan signal.

[0162] For example, the eleventh control unit B11 can control the first selection terminal IS1 to be connected to the seventh node N7 when the potential of the second scan signal is the first potential, so that the first selection signal provided by the first selection terminal IS1 can be transmitted to the seventh node N7. The eleventh control unit B11 can also control the first selection terminal IS1 to be disconnected from the seventh node N7 when the potential of the third scan signal is the second potential, so that the first selection signal provided by the first selection terminal IS1 cannot be transmitted to the seventh node N7.

[0163] The twelfth control unit B12 can be connected to a power supply terminal and the seventh node N7 respectively. The twelfth control unit B12 can be used to adjust the potential of the seventh node N7 based on the power signal provided by the power supply terminal.

[0164] Optionally, refer to Figure 21 In the scan drive unit shown, the twelfth control unit B12 is connected to a power supply terminal that is the first power supply terminal V1. Of course, it is not limited to this.

[0165] For example, taking the twelfth control unit B12 connected to the first power supply terminal V1 as an example, the twelfth control unit B12 can be used, for example, to adjust and control the potential of the seventh node N7 based on the first power supply signal provided by the first power supply terminal V1 through coupling. The control principle of the twelfth control unit B12 connected to the second power supply terminal V2 is similar and will not be repeated.

[0166] That is, in the embodiments of this application, the fifth control subunit 03211 can also be divided into two control units, similar to the first control subunit 03111, so as to reliably control the potential of the seventh node N7 through switch control and coupling control.

[0167] Optionally, in Figure 21 On this basis, Figures 22 to 24 The schematic diagram illustrates the structure of various scan drive units. (Reference) Figures 22 to 24 It can be seen that the sixth control subunit 03212 may include: the thirteenth control unit B13, and may also include at least one of the following control units: the fourteenth control unit B14, and the fifteenth control unit B15.

[0168] The thirteenth control unit B13 can be connected to the seventh node N7, the eighth node N8, and the ninth node N9 respectively. The thirteenth control unit B13 can be used to control the on / off state of the eighth node N8 and the ninth node N9 in response to the potential of the seventh node N7.

[0169] For example, the thirteenth control unit B13 can control the eighth node N8 and the ninth node N9 to be connected when the potential of the seventh node N7 is the first potential, so that the signals between the eighth node N8 and the ninth node N9 can be transmitted back and forth. The thirteenth control unit B13 can also control the eighth node N8 and the ninth node N9 to be disconnected when the potential of the seventh node N7 is the second potential, so that the signals between the eighth node N8 and the ninth node N9 cannot be transmitted back and forth.

[0170] The fourteenth control unit B14 can be connected between the eighth node N8 and a power supply terminal, and can also be connected to the second start terminal STV2. The fourteenth control unit B14 can be used to control the on / off state of a power supply terminal and the eighth node N8 in response to the second start signal.

[0171] Optionally, refer to Figure 22 and Figure 24 In the scan drive unit shown, the fourteenth control unit B14 is connected to a power supply terminal that is the first power supply terminal V1. Of course, it is not limited to this.

[0172] For example, taking the connection of the fourteenth control unit B14 to the first power supply terminal V1 as an example, the fourteenth control unit B14 can control the first power supply terminal V1 to conduct with the eighth node N8 when the potential of the second start signal is the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the eighth node N8. The fourteenth control unit B14 can also control the first power supply terminal V1 to disconnect from the eighth node N8 when the potential of the second start signal is the second potential, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the eighth node N8. The control principle of the fourteenth control unit B14 connecting to the second power supply terminal V2 is the same, and will not be repeated.

[0173] The fifteenth control unit B15 can be connected between the ninth node N9 and the second output terminal OUT2, and is also connected to the second start terminal STV2. The fifteenth control unit B15 can be used to control the on / off state of the ninth node N9 and the second output terminal OUT2 in response to the second start signal.

[0174] For example, the fifteenth control unit B15 can control the ninth node N9 to be connected to the second output terminal OUT2 when the potential of the second start signal is the first potential, so that the signal transmitted to the ninth node N9 can be further transmitted to the second output terminal OUT2 and output through the second output terminal OUT2. The fifteenth control unit B15 can also control the ninth node N9 to be disconnected from the second output terminal OUT2 when the potential of the second start signal is the second potential, so that the signal transmitted to the ninth node N9 cannot be further transmitted to the second output terminal OUT2.

[0175] That is, in one embodiment, such as Figure 22As shown, the sixth control subunit 03212 may include a thirteenth control unit B13 and a fourteenth control unit B14. In this structure, the ninth node N9 can be directly connected to the second output terminal OUT2. Alternatively, it can be understood that the sixth control subunit 03212 can be divided into two control units. One control unit is connected between the first power supply terminal V1 and the eighth node N8 to control the connection and disconnection between the first power supply terminal V1 and the eighth node N8. The other control unit is connected between the eighth node N8 and the ninth node N9 to control the connection and disconnection between the eighth node N8 and the ninth node N9. Since the ninth node N9 is directly connected to the second output terminal OUT2, it can also be understood as controlling the connection and disconnection between the eighth node N8 and the second output terminal OUT2.

[0176] Alternatively, in another embodiment, such as Figure 23 As shown, the sixth control subunit 03212 may include a thirteenth control unit B13 and a fifteenth control unit B15. In this structure, the eighth node N8 can be directly connected to a power supply terminal (e.g., the first power supply terminal V1). Alternatively, it can be understood that the sixth control subunit 03212 can be divided into two control units, with one control unit connected between the eighth node N8 and the ninth node N9 to control the on / off state of the eighth node N8 and the ninth node N9. Since the eighth node N8 is directly connected to the first power supply terminal V1, it can also be understood as controlling the on / off state of the first power supply terminal V1 and the ninth node N9. The other control unit is connected between the ninth node N9 and the second output terminal OUT2 to control the on / off state of the ninth node N9 and the second output terminal OUT2.

[0177] Alternatively, in yet another embodiment, such as Figure 24 As shown, the sixth control subunit 03212 may include a thirteenth control unit B13, a fourteenth control unit B14, and a fifteenth control unit B15. Alternatively, it can be understood that the sixth control subunit 03212 can be divided into three control units: one control unit is connected between the first power supply terminal V1 and the eighth node N8, controlling the connection and disconnection between the first power supply terminal V1 and the eighth node N8; another control unit is connected between the eighth node N8 and the ninth node N9, controlling the connection and disconnection between the eighth node N8 and the ninth node N9; and yet another control unit is connected between the ninth node N9 and the second output terminal OUT2, controlling the connection and disconnection between the ninth node N9 and the second output terminal OUT2.

[0178] In other words, if a control unit is set between the eighth node N8 and the ninth node N9, a control unit can also be set between the first power supply terminal V1 and the eighth node N8, and / or between the ninth node N9 and the second output terminal OUT2. Setting more control units can improve control reliability.

[0179] Optionally, in Figure 24 On this basis, Figure 25 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 25 It can be seen that the seventh control subunit 03221 may include: the sixteenth control unit B16 and the seventeenth control unit B17.

[0180] The sixteenth control unit B16 can be connected to the second scan terminal Scan2, the second selection terminal IS2, and the tenth node N10, respectively. The sixteenth control unit B16 can be used to control the on / off state of the second selection terminal IS2 and the tenth node N10 in response to the second scan signal.

[0181] For example, the sixteenth control unit B16 can control the second selection terminal IS2 to be connected to the tenth node N10 when the potential of the second scan signal is the first potential, so that the second selection signal provided by the second selection terminal IS2 can be transmitted to the tenth node N10. The sixteenth control unit B16 can also control the second selection terminal IS2 to be disconnected from the tenth node N10 when the potential of the second scan signal is the second potential, so that the second selection signal provided by the second selection terminal IS2 cannot be transmitted to the tenth node N10.

[0182] The seventeenth control unit B17 can be connected to another power supply terminal and the tenth node N10 respectively. The seventeenth control unit B17 can be used to adjust the potential of the tenth node N10 based on the power signal provided by the other power supply terminal.

[0183] Optionally, refer to Figure 25 In the scan drive unit shown, the seventeenth control unit B17 is connected to a second power supply terminal V2. Of course, it is not limited to this.

[0184] For example, taking the seventeenth control unit B17 connected to the second power supply terminal V2 as an example, the seventeenth control unit B17 can be used, for instance, to adjust and control the potential of the tenth node N10 based on the second power supply signal provided by the second power supply terminal V2 through coupling. The control principle of the seventeenth control unit B17 connected to the first power supply terminal V1 is similar and will not be repeated.

[0185] That is, in the embodiments of this application, the seventh control subunit 03221 can be divided into two control units to reliably control the potential of the tenth node N10 through switch control and coupling control.

[0186] Optionally, in Figure 25 On this basis, Figures 26 to 28 The schematic diagram illustrates the structure of various scan drive units. (Reference) Figures 26 to 28It can be seen that the eighth control subunit 03222 may include: the eighteenth control unit B18, and may also include at least one of the following control units: the eighteenth control unit B18, the nineteenth control unit B19, and the twentieth control unit B20.

[0187] The eighteenth control unit B18 can be connected to the tenth node N10, the eleventh node N11, and the twelfth node N12 respectively. The eighteenth control unit B18 can be used to control the on / off state of the eleventh node N11 and the twelfth node N12 in response to the potential of the tenth node N10.

[0188] For example, the eighteenth control unit B18 can control the eleventh node N11 and the twelfth node N12 to be connected when the potential of the tenth node N10 is at the first potential, so that the signal between the eleventh node N11 and the twelfth node N12 can be transmitted back and forth. The eighteenth control unit B18 can also control the eleventh node N11 and the twelfth node N12 to be disconnected when the potential of the tenth node N10 is at the second potential, so that the signal between the eleventh node N11 and the twelfth node N12 cannot be transmitted back and forth.

[0189] The nineteenth control unit B19 can be connected between the eleventh node N11 and another power supply terminal, and can also be connected to the second start terminal STV2. The nineteenth control unit B19 can be used to control the on / off state of the other power supply terminal and the eleventh node N11 in response to the second start signal.

[0190] Optionally, refer to Figures 26 to 28 In the scan drive unit shown, the nineteenth control unit B19 is connected to a second power supply terminal V2. Of course, it is not limited to this.

[0191] For example, taking the connection of the nineteenth control unit B19 to the second power supply terminal V2 as an example, the nineteenth control unit B19 can control the second power supply terminal V2 to conduct with the eleventh node N11 when the potential of the second start signal is the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the eleventh node N11. The nineteenth control unit B19 can also control the connection of the second power supply terminal V2 to the eleventh node N11 to disconnect when the potential of the first start signal is the second potential, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the eleventh node N11. The control principle of the nineteenth control unit B19 connecting to the first power supply terminal V1 is the same, and will not be repeated.

[0192] The twentieth control unit B20 can be connected between the twelfth node N12 and the second output terminal OUT2, and is also connected to the second start terminal STV2. The twentieth control unit B20 can be used to control the on / off state of the twelfth node N12 and the second output terminal OUT2 in response to the second start signal.

[0193] For example, the twentieth control unit B20 can control the twelfth node N12 to be connected to the second output terminal OUT2 when the potential of the second start signal is the first potential, so that the signal transmitted to the twelfth node N12 can be further transmitted to the second output terminal OUT2 and output through the second output terminal OUT2. The twentieth control unit B20 can also control the twelfth node N12 to be disconnected from the second output terminal OUT2 when the potential of the second start signal is the second potential, so that the signal transmitted to the twelfth node N12 cannot be further transmitted to the second output terminal OUT2.

[0194] That is, in one embodiment, such as Figure 26 As shown, the eighth control subunit 03222 may include an eighteenth control unit B18 and a nineteenth control unit B19. In this structure, the twelfth node N12 can be directly connected to the second output terminal OUT2. Alternatively, it can be understood that the eighth control subunit 03222 can be divided into two control units. One control unit is connected between the second power supply terminal V2 and the eleventh node N11 to control the connection and disconnection between the second power supply terminal V2 and the eleventh node N11. The other control unit is connected between the eleventh node N11 and the twelfth node N12 to control the connection and disconnection between the eleventh node N11 and the twelfth node N12. Since the twelfth node N12 is directly connected to the second output terminal OUT2, it can also be understood as controlling the connection and disconnection between the eleventh node N11 and the second output terminal OUT2.

[0195] Alternatively, in another embodiment, such as Figure 27 As shown, the eighth control subunit 03222 may include an eighteenth control unit B18 and a twentieth control unit B20. In this structure, the eleventh node N11 can be directly connected to a power supply terminal (e.g., the second power supply terminal V2). Alternatively, it can be understood that the eighth control subunit 03222 can be divided into two control units, with one control unit connected between the eleventh node N11 and the twelfth node N12 to control the on / off state of the eleventh node N11 and the twelfth node N12. Since the eleventh node N11 is directly connected to the second power supply terminal V2, it can also be understood as controlling the on / off state of the second power supply terminal V2 and the eleventh node N11. The other control unit is connected between the twelfth node N12 and the second output terminal OUT2 to control the on / off state of the twelfth node N12 and the second output terminal OUT2.

[0196] Alternatively, in yet another embodiment, such as Figure 28As shown, the eighth control subunit 03222 may include an eighteenth control unit B18, a nineteenth control unit B19, and a twentieth control unit B20. Alternatively, it can be understood that the eighth control subunit 03222 can be divided into three control units, with one control unit connected between the second power supply terminal V2 and the eleventh node N11 to control the on / off state of the second power supply terminal V2 and the eleventh node N11; another control unit connected between the eleventh node N11 and the twelfth node N12 to control the on / off state of the eleventh node N11 and the twelfth node N12; and yet another control unit connected between the twelfth node N12 and the second output terminal OUT2 to control the on / off state of the twelfth node N12 and the second output terminal OUT2.

[0197] In other words, if a control unit is installed between the eleventh node N11 and the twelfth node N12, a control unit can also be installed between the second power supply terminal V2 and the eleventh node N11, and / or, a control unit can also be installed between the twelfth node N12 and the second output terminal OUT2. Installing more control units can improve control reliability.

[0198] It is understood that the solutions shown in the above figures are all illustrated by taking the example of the first output terminal OUT1 and the second output terminal OUT2 being directly connected to the shared light-emitting control terminal EM or the privacy-protected light-emitting control terminal EM via the same output terminal control terminal OUT_EM. This is one solution protected by the embodiments of this application. Based on this solution, the first output signal output through the first output terminal OUT1 and the second output signal output through the second output terminal OUT2 can both be directly used as shared light-emitting control signals and transmitted to the shared light-emitting control terminal EM via the output control terminal OUT_EM; or, directly used as privacy-protected light-emitting control signals and transmitted to the privacy-protected light-emitting control terminal EM via the output control terminal OUT_EM.

[0199] However, in another scheme, the first output terminal OUT1 and the second output terminal OUT2 can also be indirectly connected to the same output terminal control terminal OUT_EM, thereby indirectly connecting to the shared light-emitting control terminal EM or the privacy-protected light-emitting control terminal EM.

[0200] For example, in Figure 6 Based on, combined Figure 29 As can be seen from the schematic diagram of another scanning drive unit shown, in this alternative scheme, each output control circuit 03 may also include a third control sub-circuit 033.

[0201] The third control sub-circuit 033 can be connected to the corresponding shared light-emitting control terminal EM shared or privacy-preventing light-emitting control terminal EM privacy, and can also be connected to the first output terminal OUT1, the second output terminal OUT2, the first power supply terminal V1, and the second power supply terminal V2 respectively. The third control sub-circuit 033 can be used to control the on / off state of each signal terminal in the first power supply terminal V1 and the second power supply terminal V2 with the corresponding connected shared light-emitting control terminal EM shared or privacy-preventing light-emitting control terminal EM privacy in response to the first power signal provided by the first power supply terminal V1, the second power signal provided by the second power supply terminal V2, the first output signal, and the second output signal.

[0202] That is, such as Figure 29 As shown, the first output terminal OUT1 of the first control sub-circuit 031 can be indirectly connected to the output control terminal OUT_EM via the third control sub-circuit 033; the second output terminal OUT2 of the second control sub-circuit 032 can be indirectly connected to the output control terminal OUT_EM via the third control sub-circuit 033; the output control terminal OUT_EM is connected to the shared light-emitting control terminal EM (shared) or the privacy-protected light-emitting control terminal EM (privacy-protected).

[0203] Optionally, in Figure 29 Based on the combination Figure 28 , Figure 30 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 30 It can be seen that the third control sub-circuit 033 may include: the fifth control unit 0331 and the sixth control unit 0332.

[0204] The fifth control unit 0331 can be connected to the first power supply terminal V1, the second power supply terminal V2, the first output terminal OUT1, and the second output terminal OUT2, respectively. The fifth control unit 0331 can be used to regulate the first output signal based on the first power supply signal and to regulate the second output signal based on the second power supply signal.

[0205] For example, the fifth control unit 0331 can, for instance, regulate and control the first output signal output through the first output terminal OUT1 based on the first power supply signal, and regulate and control the second output signal output through the second output terminal OUT2 based on the second power supply signal, for example, through coupling.

[0206] The sixth control unit 0332 can be connected to the corresponding shared light-emitting control terminal EM (shared) or privacy-protected light-emitting control terminal EM (privacy-protected), and can also be connected to the first power supply terminal V1, the second power supply terminal V2, the first output terminal OUT1, and the second output terminal OUT2, respectively. The sixth control unit 0332 can, in response to the first output signal and the second output signal, control the on / off state of each signal terminal in the first power supply terminal V1 and the second power supply terminal V2 with the corresponding connected shared light-emitting control terminal EM (shared) or privacy-protected light-emitting control terminal EM (privacy-protected).

[0207] That is, the sixth control unit 0332 can be connected to the shared light control terminal EM or the privacy light control terminal EM via the output control terminal OUT_EM.

[0208] Furthermore, for example, the sixth control unit 0332 can control the first power supply terminal V1 to be connected to the output control terminal OUT_EM and control the second power supply terminal V2 to be disconnected from the output control terminal OUT_EM when the potential of the first output signal is the first potential and the potential of the second output signal is the second potential. This allows the first power signal provided by the first power supply terminal V1 to be transmitted to the corresponding shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM, and prevents the second power signal provided by the second power supply terminal V2 from being transmitted to the corresponding shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM. The sixth control unit 0332 can control the second power supply terminal V2 to conduct with the output control terminal OUT_EM when the potential of the second output signal is the first potential and the potential of the first output signal is the second potential, and control the first power supply terminal V1 to disconnect from the output control terminal OUT_EM. This allows the second power signal provided by the second power supply terminal V2 to be transmitted to the corresponding shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM, and prevents the first power signal provided by the first power supply terminal V1 from being transmitted to the corresponding shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM.

[0209] That is, in this embodiment of the application, the third control sub-circuit 033 can be divided into two control units, and one control unit is set to control the output signal; the other control unit is set to control the on / off of each signal terminal in the first power terminal V1 and the second power terminal V2 and the corresponding connected shared light-emitting control terminal EM or privacy light-emitting control terminal EM, so as to output a high-potential first power signal or a low-potential second power signal to both the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM.

[0210] Optionally, in Figure 30 On this basis, Figure 31 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 31 It can be seen that the fifth control unit 0331 may include: the ninth control subunit 03311 and the tenth control subunit 03312.

[0211] The ninth control subunit 03311 can be connected to the first power supply terminal V1 and the first output terminal OUT1 respectively. The ninth control subunit 03311 can be used to regulate the first output signal based on the first power supply signal.

[0212] For example, the ninth control subunit 03311 can adjust and control the first output signal output through the first output terminal OUT1 based on the first power supply signal through coupling.

[0213] The tenth control subunit 03312 can be connected to the second power supply terminal V2 and the second output terminal OUT2 respectively. The tenth control subunit 03312 can be used to regulate the second output signal based on the second power supply signal.

[0214] For example, the tenth control subunit 03312 can adjust and control the second output signal output through the second output terminal OUT2 based on the second power supply signal through coupling.

[0215] That is, in the embodiments of this application, the fifth control unit 0331 can be divided into two control subunits, and one control subunit is configured to regulate the first output signal based on the first power signal; the other control subunit is configured to regulate the second output signal based on the second power signal.

[0216] Optionally, in Figure 31 On this basis, Figure 32 A schematic diagram of another scanning drive unit is shown. (Reference) Figure 32 It can be seen that the sixth control unit 0332 may include: the eleventh control subunit 03321 and the twelfth control subunit 03322.

[0217] The eleventh control subunit 03321 can be connected to the corresponding shared light-emitting control terminal (EM shared) or the privacy light-emitting control terminal (EM privacy), and can also be connected to the first output terminal OUT1 and the first power supply terminal V1 respectively. The eleventh control subunit 03321 can be used to control the on / off state of the first power supply terminal V1 and the corresponding connected shared light-emitting control terminal (EM shared) or privacy light-emitting control terminal (EM privacy) in response to the first output signal. That is, as... Figure 32 As shown, the eleventh control subunit 03321 can be connected to the output control terminal OUT_EM, so as to connect to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM.

[0218] For example, the eleventh control subunit 03321 can control the first power supply terminal V1 to be connected to the output control terminal OUT_EM when the potential of the first output signal is the first potential, so that the first power signal provided by the first power supply terminal V1 can be transmitted to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. The eleventh control subunit 03321 can also control the first power supply terminal V1 to be disconnected from the output control terminal OUT_EM when the potential of the first output signal is the second potential, so that the first power signal provided by the first power supply terminal V1 cannot be transmitted to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM.

[0219] The twelfth control subunit 03322 is used to connect to the corresponding shared light-emitting control terminal EM (shared) or privacy-protected light-emitting control terminal EM (privacy-protected), and can also be connected to the second output terminal OUT2 and the second power supply terminal V2 respectively. The twelfth control subunit 03322 can be used to control the on / off state of the second power supply terminal V2 and the corresponding connected shared light-emitting control terminal EM (shared) or privacy-protected light-emitting control terminal EM (privacy-protected) in response to the second output signal. That is, as... Figure 32 As shown, the twelfth control subunit 03322 can be connected to the output control terminal OUT_EM, so as to connect to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM via the output control terminal OUT_EM.

[0220] For example, the twelfth control subunit 03322 can control the second power supply terminal V2 to be connected to the output control terminal OUT_EM when the potential of the second output signal is the first potential, so that the second power signal provided by the second power supply terminal V2 can be transmitted to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. The twelfth control subunit 03322 can also control the second power supply terminal V2 to be disconnected from the output control terminal OUT_EM when the potential of the second output signal is the second potential, so that the second power signal provided by the second power supply terminal V2 cannot be transmitted to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM.

[0221] That is, in this embodiment of the application, the sixth control unit 0332 can be divided into two control sub-units, and one of the control sub-units is set to control the on / off state of the first power supply terminal V1 and the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM under the control of the first output signal; the other control sub-unit is set to control the on / off state of the second power supply terminal V2 and the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM under the control of the second output signal.

[0222] Therefore, it can be seen that, based on this alternative scheme, since a third control sub-circuit 033 is also set, it is combined with... Figures 29 to 32 It can be seen that the first scanning end Scan1 and the second scanning end Scan2 can share the same scanning end Scan. The first start end STV1 and the second start end STV2 can share the same start end STV. And, Figure 5 The first shift circuit 01 and the second shift circuit 02 shown can be combined into a single shift circuit. This simplifies the structure, saves space, and facilitates narrow bezel design.

[0223] Furthermore, it is understandable that in this alternative approach, combining Figures 30 to 32 It can also be seen that in the first control sub-circuit 031, one power supply terminal connected to the first control unit 0311 can be the first power supply terminal V1, and correspondingly, the other power supply terminal connected to the second control unit 0312 can be the second power supply terminal V2. Furthermore, in the second control sub-circuit 032, one power supply terminal connected to the third control unit 0321 can be the second power supply terminal V2, and correspondingly, the other power supply terminal connected to the fourth control unit 0322 can be the first power supply terminal V1. Of course, this is not the only possibility.

[0224] Optionally, in the embodiments of this application, the transistors connected to the first output terminal OUT1 and the first start terminal STV1 in the first control unit 0311 and the second control unit 0312 share the same transistor.

[0225] That is, combining Figures 30 to 33 It can be seen that the fifth control unit B5 in the first control unit 0311, which is connected between the third node N3 and the first output terminal OUT1 and also connected to the first starting terminal STV1, and the tenth control unit B10 in the second control unit 0312, which is connected between the sixth node N6 and the first output terminal OUT1 and also connected to the first starting terminal STV1, can be shared as the same control unit and can be designed with the same transistor. This simplifies the structure, saves space, and facilitates narrow bezel design.

[0226] Optionally, in the embodiments of this application, the transistors connected to the second output terminal OUT2 and the second start terminal STV2 in the third control unit 0321 and the fourth control unit 0322 share the same transistor.

[0227] That is, combining Figures 30 to 33It can be seen that the fifteenth control unit B15 in the third control unit 0321, which is connected between the ninth node N9 and the second output terminal OUT2 and is also connected to the second starting terminal STV2, and the twentieth control unit B20 in the fourth control unit 0322, which is connected between the twelfth node N12 and the second output terminal OUT2 and is also connected to the second starting terminal STV2, can share the same control unit and can be designed with the same transistor. In this way, the structure can be simplified, space can be saved, and narrow bezel design can be facilitated.

Similarly, the sixth control subunit 03212 may include: a fourteenth control unit B14 and / or a fifteenth control unit B15; the eighth control subunit 03222 may include: a nineteenth control unit B19 and / or a twentieth control unit B20; of course, the fifteenth control unit B15 and the twentieth control unit B20 may be shared as one control unit.

When the eighteenth control unit B18 is provided between the eleventh node N11 and the twelfth node N12, a nineteenth control unit B19 can also be provided between the eleventh node N11 and the first power supply terminal V1, and a twentieth control unit B20 can be provided between the twelfth node N12 and the second output terminal OUT2. Furthermore, the fifteenth control unit B15 and the twentieth control unit B20, which are both connected to the second output terminal OUT2 and the second start terminal STV2, share the same control unit.

Based on Embodiment 2, transistors T1, T2, and T4, along with capacitor C1, form one group; transistors T5, T6, and T8, along with capacitor C2, form another group; transistors T9, T10, and T12, along with capacitor C3, form one group; and transistors T13, T14, and T16, along with capacitor C4, form another group.

[0270] Example 3: Figure 37 The 4T1C architecture shown has four groups in total (top, bottom, left, and right). Compared to Embodiment 1, it combines Embodiment 1 and Embodiment 2 by placing an STV TFT between the power supply terminal and the output TFT, and also placing an STV TFT between the output TFT and the output control terminal OUT_EM. Based on Embodiment 3, transistors T1 to T4 and capacitor C1 form one group; transistors T5 to T8 and capacitor C2 form one group; transistors T9 to T12 and capacitor C3 form one group; and transistors T13 to T16 and capacitor C4 form one group.

[0271] The above embodiments 1 to 3 represent a scheme in which both the first output terminal OUT1 and the second output terminal OUT2 are directly connected to the output control terminal OUT_EM. Alternatively, [the following can be done]... Figures 35 to 37 The structures shown are divided into left and right parts. The left part includes a structure connecting the first scanning end Scan1, the first starting end STV1 and the first output end OUT1. The right part includes a structure connecting the second scanning end Scan2, the second starting end STV2 and the second output end OUT2.

[0272] Therefore, for example, in the refresh frame, the first scanning terminal Scan1 can be controlled to provide a valid first scan signal, and the second scanning terminal Scan2 can be controlled to provide an invalid second scan signal, so that the left part switches normally, and transmits a high-potential power signal or a low-potential power signal to the corresponding connected shared light-emitting control terminal EM or privacy light-emitting control terminal EM via the first output terminal OUT1, driving the shared light-emitting element L1 or the privacy light-emitting element L1 to emit light. In the hold frame, the second scanning terminal Scan2 can be controlled to provide a valid second scan signal, and the first scanning terminal Scan1 can be controlled to provide an invalid first scan signal, so that the right part switches normally, and transmits a high-potential power signal or a low-potential power signal to the corresponding connected shared light-emitting control terminal EM or privacy light-emitting control terminal EM via the second output terminal OUT2, driving the shared light-emitting element L1 or the privacy light-emitting element L1 to emit light. Of course, the refresh frame and hold frame can also be interchanged. In the refresh frame, the second scan terminal Scan2 is controlled to provide a valid second scan signal, while the first scan terminal Scan1 is controlled to provide an invalid first scan signal, allowing the right side to switch normally. In the hold frame, the first scan terminal Scan1 is controlled to provide a valid first scan signal, while the second scan terminal Scan2 is controlled to provide an invalid second scan signal, allowing the left side to switch normally. The two stages can complement each other to achieve a complete output. However, the refresh frame and hold frame are merely illustrative examples illustrating the time-sharing principle and are not limited to time-sharing control of refresh and hold frames. In some embodiments, the left and right sides can be flexibly opened and closed cyclically using the refresh frame as a period.

[0273] Understandably, taking the left side as an example, when the first scan terminal Scan1 provides a valid first scan signal, the potential of the first start signal provided by the first start terminal STV1 can be an invalid potential. In this case, the first selection signal provided by the first selection terminal IS1 and the second selection signal provided by the second selection terminal IS2 can be written to the corresponding capacitors, thereby controlling the voltage stored in the capacitors according to the first and second selection signals. Afterwards, the first start terminal STV1 can be controlled to provide a valid first start signal. Based on the first start signal, the first selection signal, and the second selection signal, the pull-up power supply terminal VGH can be controlled to output a high-potential power signal to the first output terminal OUT1, or the pull-down power supply terminal VGL can be controlled to output a low-potential power signal to the first output terminal OUT1. The right side is similar and will not be repeated.

[0274] Example 4: Figure 38The diagram shows four 3T1C architectures (top, bottom, left, and right) and one 2T2C architecture connected between the first output terminal OUT1, the second output terminal OUT2, and the output control terminal OUT_EM. The four 3T1C architectures are... Figure 35 As shown, the difference lies in that the output TFT of embodiment 4 is not directly connected to the output control terminal OUT_EM, but is indirectly connected to the output control terminal OUT_EM through a 2T2C architecture. The 2T2C architecture includes two transistors and two capacitors, wherein the two transistors are respectively connected between the first output terminal OUT1 and the output control terminal OUT_EM, and between the second output terminal OUT2 and the output control terminal OUT_EM.

[0275] Example 5: Figure 39 The diagram shows four 2T1C architectures arranged vertically and horizontally, and two more 2T1C architectures connected between the first output terminal OUT1 / second output terminal OUT2 and the output control terminal OUT_EM. The four 2T1C architectures are: one consisting of transistors T1 and T2 and capacitor C1; one consisting of transistors T5 and T6 and capacitor C2; one consisting of transistors T9 and T10 and capacitor C3; and one consisting of transistors T13 and T14 and capacitor C4. The two 2T1C architectures are: one consisting of transistors T4 / T8 and T17 sharing the same transistor and capacitor C5; and one consisting of transistors T12 / T16 and T18 sharing the same transistor and capacitor C6. This can also be considered as a difference from embodiment 4, where the STV TFT is changed from being located between the power supply terminal and the output TFT to being located between the output TFT and the output control terminal OUT_EM, and the transistors T4 and T8 connected to the first output terminal OUT1 and the starting terminal STV are set to share the same transistor, and the transistors T12 and T16 connected to the second output terminal OUT2 and the starting terminal STV are set to share the same transistor.

[0276] Example 6: Figure 40The diagram shows four 3T1C architectures (top, bottom, left, and right) and two 2T1C architectures connected between the first output terminal OUT1 / second output terminal OUT2 and the output control terminal OUT_EM. The four 2T1C architectures are: one consisting of transistors T1 to T3 and capacitor C1; one consisting of transistors T5 to T7 and capacitor C2; one consisting of transistors T9 to T11 and capacitor C3; and one consisting of transistors T13 to T15 and capacitor C4. The two 2T1C architectures are: one consisting of transistors T4 / T8 and T17 sharing the same transistor and capacitor C5; and one consisting of transistors T12 / T16 and T18 sharing the same transistor and capacitor C6. This can also be considered as a difference from Embodiment 4. In addition to setting an STV TFT between the power supply terminal and the output TFT, an STV TFT is also set between the output TFT and the output control terminal OUT_EM. Furthermore, the transistors T4 and T8 connecting the first output terminal OUT1 and the starting terminal STV share the same transistor, and the transistors T12 and T16 connecting the second output terminal OUT2 and the starting terminal STV share the same transistor. This is a combination of Embodiment 4 and Embodiment 5.

[0277] The above embodiments 4 and 5 represent another scheme where both the first output terminal OUT1 and the second output terminal OUT2 are indirectly connected to the output control terminal OUT_EM through the third control sub-circuit 033. Similarly, it is also possible to... Figures 38 to 40 The structures shown are divided into left and right parts. The left part includes a structure connecting the first scanning end Scan1, the first starting end STV1 and the first output end OUT1. The right part includes a structure connecting the second scanning end Scan2, the second starting end STV2 and the second output end OUT2.

[0278] Therefore, for example, a shared scanning terminal Scan for both the left and right sides can be configured to provide effective potential scanning signals column by column, allowing the left and right sides to alternately switch on and off column by column. This transmits high-potential or low-potential power signals to the corresponding connected shared light-emitting control terminal EM or privacy-protected light-emitting control terminal EM, driving the shared light-emitting element L1 or the privacy-protected light-emitting element L1 to emit light. The switching control logic is the same as one of the schemes shown in Embodiments 1 to 3 above, and will not be repeated here. Here, "column by column" refers to a pixel column.

[0279] It is understandable that, based on the above-mentioned scheme, the first selection signal and the second selection signal can be intercepted using the first scan signal and the second scan signal, thereby achieving control over the shared EM control terminal or the privacy EM control terminal connected to different pixels. Furthermore, by alternately activating the first start signal and the second start signal, the left and right portions can work alternately, achieving continuous and reliable output. Combined with... Figure 4 The one-to-two pixel design shown enables locally switchable positional refresh control for high-PPI displays. Building upon the aforementioned alternative scheme, the first and second selection signals can also be intercepted via scanning signals to control either the shared EM (Emitting Microwave Oxidation) control terminal or the privacy EM control terminal connected to different pixels. Furthermore, the capacitor can be charged during the blanking phase of the refresh frame using a shared start signal, achieving continuous and reliable output. In addition, compared to the first scheme, it reduces one shift circuit, resulting in a simpler structure, lower cost, and better suitability for narrow bezel designs.

[0280] Optionally, Figures 35 to 40 In the scan drive unit shown, each transistor can be a P-type transistor. Of course, it is not limited to this.

[0281] Optionally, the first shift circuit 01 and the second shift circuit 02 described in the embodiments of this application can both be a shift register unit, also known as a GOA unit, which is often integrated on the display substrate and cascaded.

[0282] For example, Figure 41 A schematic diagram of the circuit structure of a GOA unit is shown. (Combined with...) Figure 41 It can be seen that both the first shift circuit 01 and the second shift circuit 02 can be the 8T2C architecture shown in the figure, that is, including 8 transistors T01 to T08, and 2 capacitors C01 and C02.

[0283] In this configuration, transistor T01's gate can be connected to the first clock terminal CK, its first electrode can be connected to the input signal terminal IN, and its second electrode can be connected to the intermediate node Q0. Transistor T02's gate can be connected to the intermediate node Q0, its first electrode can be connected to the first clock terminal CK, and its second electrode can be connected to the pull-down node QB. Transistor T03's gate can be connected to the first clock terminal CK, its first electrode can be connected to the pull-down power supply terminal VGL, and its second electrode can be connected to the pull-down node QB. Transistor T04's gate can be connected to the pull-down node QB, its first electrode can be connected to the pull-up power supply terminal VGH, and its second electrode can be connected to the output signal terminal OUT. Transistor T05's gate can be connected to the pull-up node Q, its first electrode can be connected to the second clock terminal CB, and its second electrode can be connected to the output signal terminal OUT. The gate of transistor T06 can be connected to the pull-down node QB, the first terminal of transistor T06 can be connected to the pull-up power supply VGH, and the second terminal of transistor T06 can be connected to the first terminal of transistor T07. The gate of transistor T07 can be connected to the second clock terminal CB, and the second terminal of transistor T07 can be connected to the intermediate node Q0. The gate of transistor T08 can be connected to the pull-down power supply VGL, the first terminal of transistor T08 can be connected to the intermediate node Q0, and the second terminal of transistor T08 can be connected to the pull-up node Q. Capacitor C01 can be connected between the pull-up node Q and the output signal terminal OUT. Capacitor C02 can be connected between the pull-up power supply VGH and the pull-down node QB.

[0284] It is understandable that the first shift circuit 01 can be connected to the first scan terminal Scan1 via its own output signal terminal OUT to provide the required first scan signal to the first scan terminal Scan1. Similarly, the second shift circuit 02 can be connected to the second scan terminal Scan2 via its own output signal terminal OUT to provide the required second scan signal to the second scan terminal Scan2.

[0285] It is also understandable that, taking the first shift circuit 01 as an example, its output signal terminal OUT can also be connected to the input signal terminal IN of other cascaded shift register units to provide the required input signals to the input signal terminals IN of other shift register units, thereby achieving reliable cascaded shift drive. Of course, for the first-stage first shift circuit 01, its input signal terminal IN can also be connected to a separate start signal terminal STV01 to receive the start signal provided by the start signal terminal STV01 and, in response to the start signal, initiate the shift function to achieve cascade drive. Similarly, for the second shift circuit 02, its output signal terminal OUT can also be connected to the input signal terminal IN of other cascaded shift register units to provide the required input signals to the input signal terminals IN of other shift register units, thereby achieving reliable cascaded shift drive. Of course, for the first-stage second shift circuit 02, its input signal terminal IN can also be connected to a separate start signal terminal STV02 to receive the start signal provided by the start signal terminal STV02 and, in response to the start signal, initiate the shift function to achieve cascade drive. Furthermore, in some embodiments, the first starting terminal STV1 connected to the output control circuit 03 described above can also share the same signal terminal as the starting signal terminal STV01 connected to the first shift circuit 01, and the second starting terminal STV2 connected to the output control circuit 03 can also share the same signal terminal as the starting signal terminal STV02 connected to the second shift circuit 02.

[0286] Optionally, Figure 41 In the GOA unit shown, each transistor can be a P-type transistor. However, it is not limited to this. Furthermore, the GOA unit provided in the embodiments of this application is not limited to... Figure 41 The 8T2C architecture is shown.

[0287] In summary, this application provides a scanning driving unit. Because the output control circuit in a single scanning driving unit can control the on / off state of the shared light-emitting control terminal and the privacy-protecting light-emitting control terminal connected to a pixel via different power supply terminals under the control of various signals such as the received scanning signal, start signal, and selection signal, the power supply signal can be flexibly set so that the single scanning driving unit simultaneously provides shared light-emitting control signals and privacy-protecting light-emitting control signals of different potentials to the shared light-emitting control terminal and the privacy-protecting light-emitting control terminal. That is, the privacy-protecting display mode and the shared display mode can be flexibly switched through the same pixel circuit. Thus, it does not limit the development of display panels towards higher resolution, and can simultaneously achieve high-resolution display with privacy-protecting and shared switching functions.

[0288] This application also provides a driving method for a scan driving unit, used to drive the scan driving unit as described above. Figure 42 As shown, the method includes: Step 4201: In the shared mode, the first shift circuit transmits a first scan signal with a first potential to the first scan terminal in a time-division manner, and transmits a second scan signal with a first potential to the second scan terminal. The potential of the first selection signal provided by the first selection terminal is the first potential, and the potential of the second selection signal provided by the second selection terminal is the second potential. Each output control circuit responds to the first scan signal, the first start signal provided by the first start terminal, the second scan signal, the second start signal provided by the second start terminal, the first selection signal, and the second selection signal, and controls the first power supply terminal to be connected to the corresponding shared light emission control terminal or the privacy light emission control terminal, and controls the second power supply terminal to be disconnected from the corresponding shared light emission control terminal or the privacy light emission control terminal.

[0289] Step 4202: In the privacy mode, the first shift circuit transmits a first scan signal with a first potential to the first scan terminal in a time-division manner, and transmits a second scan signal with a first potential to the second scan terminal. The potential of the first selection signal provided by the first selection terminal is the second potential, and the potential of the second selection signal provided by the second selection terminal is the first potential. The output control circuit responds to the first scan signal, the first start signal provided by the first start terminal, the second scan signal, the second start signal provided by the second start terminal, the first selection signal, and the second selection signal, and controls the second power supply terminal to be connected to the corresponding shared light emission control terminal or the privacy light emission control terminal, and controls the first power supply terminal to be disconnected from the corresponding shared light emission control terminal or the privacy light emission control terminal.

[0290] Optionally, as described above, the first shift circuit transmits a first scan signal with a first potential to the first scan terminal in a time-division manner, and transmits a second scan signal with a first potential to the second scan terminal, including: During the refresh frame and hold frame, the first shift circuit transmits a first scan signal with a first potential to the first scan terminal in a time-division manner, and transmits a second scan signal with a first potential to the second scan terminal.

[0291] Alternatively, during the refresh frame, the first shift circuit transmits a first scan signal with a first potential to the first scan terminal and a second scan signal with a first potential to the second scan terminal in a time-division manner for different column pixels.

[0292] Based on the above embodiments, firstly, with Figure 41 The GOA cell structure shown is an example where all transistors in the GOA cell are P-type transistors, with the effective potential being low and the inactive potential being high. Figure 43 A schematic diagram illustrating the timing of a GOA (Getting Over-Ahead) unit is shown. Figure 43 The working principle of the GOA unit (i.e., the first shift circuit 01 or the second shift circuit 02) is explained as follows: In the first stage A1, the input signal provided by the input signal terminal IN can be at a low potential, the first clock signal provided by the first clock terminal CK can be at a low potential, and the second clock signal provided by the second clock terminal CB can be at a high potential. Correspondingly, transistors T01 and T03 can be turned on, and transistor T07 can be turned off. This allows the low-potential input signal provided by the input signal terminal IN to be transmitted to the intermediate node Q0 via the turned-on transistor T01, controlling the potential of the intermediate node Q0 to be low. Similarly, the low-potential power signal provided by the pull-down power supply terminal VGL can be transmitted to the pull-down node QB via the turned-on transistor T03, controlling the potential of the pull-down node QB to be low. Furthermore, under the control of the low-potential power signal provided by the pull-down power supply terminal VGL, transistor T08 can also be turned on, allowing the low-potential input signal transmitted to the intermediate node Q0 to be further transmitted to the pull-up node Q, controlling the potential of the pull-up node Q to also be low. With the potentials of intermediate node Q0, pull-up node Q, and pull-down node QB all at low levels, transistors T04, T05, and T06 can be further turned on. This allows the high-potential power signal supplied by the pull-up power supply terminal VGH to be transmitted to the first terminal of transistor T07 via the turned-on transistor T06, but because transistor T07 is turned off, it will not be further transmitted to intermediate node Q0. Furthermore, the high-potential second clock signal can be transmitted to the output terminal OUT via the turned-on transistor T05, and the high-potential power signal supplied by the pull-up power supply terminal VGH can be transmitted to the output terminal OUT via the turned-on transistor T04. That is, in this first stage A1, the shift circuit O1 can output a high-potential output signal via the output signal terminal OUT.

[0293] In the second stage A2, the potential of the input signal provided by the input signal terminal IN can become high, the potential of the first clock signal provided by the first clock terminal CK can become high, and the potential of the second clock signal provided by the second clock terminal CB can undergo a high-to-low transition. Correspondingly, transistors T01 and T03 can be turned off, and transistor T07 can be turned on. At this time, the potential of the intermediate node Q0 can be maintained at the low potential of the previous stage. Thus, transistor T02 can also be turned on. Furthermore, the high-potential first clock signal provided by the first clock terminal CK can be transmitted to the pull-down node QB via the turned-on transistor T02, controlling the potential of the pull-down node QB to be high. Thus, transistor T06 can be further turned off. Furthermore, the high-potential power signal provided by the pull-up power supply terminal VGH will not be transmitted to the intermediate node Q0, thus not affecting the low potential of the intermediate node Q0. Also, because the second clock signal undergoes a high-to-low transition, the pull-up node Q can be pulled down to a lower potential, controlling transistor T05 to be fully turned on. With the pull-up node Q at a low potential and the pull-down node QB at a high potential, transistor T04 can be further controlled to turn off, and transistor T05 can be controlled to turn on. This allows the low-potential second clock signal to be transmitted to the output terminal OUT via the turned-on transistor T05. That is, in this second stage A2, shift circuit 01 can output high and low bit output signals via the output signal terminal OUT.

[0294] In the third stage A3, the input signal provided by the input signal terminal IN can be at a high potential, the first clock signal provided by the first clock terminal CK can transition from a high potential to a low potential, and the second clock signal provided by the second clock terminal CB can also become high. Correspondingly, transistors T01 and T03 can be turned on, and transistor T07 can be turned off. This allows the high-potential input signal from the input signal terminal IN to be transmitted to the intermediate node Q0 via the turned-on transistor T01, controlling the potential of the intermediate node Q0 to be high. Simultaneously, the low-potential power signal from the pull-down power supply terminal VGL can be transmitted to the pull-down node QB via the turned-on transistor T03, controlling the potential of the pull-down node QB to be low. Furthermore, under the control of the low-potential power signal from the pull-down power supply terminal VGL, transistor T08 can also be turned on, allowing the high-potential input signal transmitted to the intermediate node Q0 to be further transmitted to the pull-up node Q, controlling the potential of the pull-up node Q to also be high. With the potentials of intermediate node Q0 and pull-up node Q high, and pull-down node QB low, transistors T04 and T06 can be further turned on, while transistor T05 is turned off. This allows the high-potential power signal provided by the pull-up power supply terminal VGH to be transmitted to the first terminal of transistor T07 via the turned-on transistor T06, but because transistor T07 is turned off, it will not be further transmitted to intermediate node Q0. Furthermore, the high-potential power signal provided by the pull-up power supply terminal VGH can also be transmitted to the output terminal OUT via the turned-on transistor T04. That is, in this third stage A3, shift circuit 01 can output a high-potential output signal via the output signal terminal OUT.

[0295] For example, Figure 43 The diagram illustrates the output signals of the GOA unit via output signal terminals OUT_1 and OUT_2 for the pixels in rows 1 and 2. Generally, each GOA unit corresponds to one row of pixels, but this is not a limitation.

[0296] Secondly, based on the above introduction to the working principle of the GOA unit, with Figure 35 The diagram illustrates a structure where each transistor is a P-type transistor with an effective potential of low and an ineffective potential of high. Taking the example of a first power supply terminal V1 providing a high-potential first power signal and a second power supply terminal V2 providing a low-potential second power signal... Figure 44 and Figure 45 The following are schematic diagrams illustrating the operating timing of an output control circuit 03. Figure 44 and Figure 45 The working principle of the output control circuit 03 of this scheme is explained as follows: by Figure 44For example, in the refresh frame shown, the potential of the first scan signal provided by the first scan terminal Scan1 includes a low potential, while the potential of the second scan signal provided by the second scan terminal Scan2 remains high; in the hold frame shown, the potential of the second scan signal provided by the second scan terminal Scan2 includes a low potential, while the potential of the first scan signal provided by the first scan terminal Scan1 remains high. Furthermore, Figure 44 The diagram schematically illustrates the first scan signals provided by n first scan terminals Scan1, labeled Scan1_1 to Scan1_n, and schematically illustrates the second scan signals provided by n second scan terminals Scan2, labeled Scan2_1 to Scan2_n, where n is an integer greater than 1. Generally, the output signal OUT of a first-stage first shift circuit 01 is connected to one first scan terminal Scan1, and the output signal OUT of a first-stage second shift circuit 02 is connected to one second scan terminal Scan2. Correspondingly, this includes n-stage first shift circuits 01 and n-stage second shift circuits 02. Furthermore, in conjunction with... Figure 44 It can also be seen that, in the refresh frame, the potential of the first selection signal provided by the first selection terminal IS1 includes sequentially changing high and low potentials; the potential of the second selection signal provided by the second selection terminal IS2 includes sequentially changing low and high potentials; and the potential of the first start signal provided by the first start terminal STV1 remains high, while the potential of the second start signal provided by the second start terminal STV2 remains low. In the hold frame, the potential of the first selection signal provided by the first selection terminal IS1 includes sequentially changing high and low potentials; the potential of the second selection signal provided by the second selection terminal IS2 includes sequentially changing low and high potentials; and the potential of the first start signal provided by the first start terminal STV1 remains low, while the potential of the second start signal provided by the second start terminal STV2 remains high. Furthermore, during the transition phase between the refresh frame and the hold frame, the potential of the first scan signal provided by the first scan terminal Scan1 and the potential of the second scan signal provided by the second scan terminal Scan2 are both kept at a high potential; the potential of the first start signal provided by the first start terminal STV1 alternately jumps between a high potential and a low potential; the potential of the second start signal provided by the second start terminal STV2 alternates between a low potential and a high potential; the potential of the first selection signal provided by the first selection terminal IS1 is kept at a low potential, and the potential of the second selection signal provided by the second selection terminal IS2 is kept at a high potential.

[0297] Based on this, combine Figure 35As can be seen, for example, during frame refresh, because the potential of the second scan signal remains high, the ninth transistor T9 and the thirteenth transistor T13 on the right side can be turned off, thereby disconnecting the first start terminal IS1 from the seventh node N7, and disconnecting the second start terminal IS2 from the tenth node N10. Because the potential of the first start signal provided by the first start terminal STV1 remains high, the third transistor T3 and the seventh transistor T7 on the left side can be turned off, thereby disconnecting the first power supply terminal V1 from the second node N2, and disconnecting the second power supply terminal V2 from the fifth node N5. Because the potential of the second start signal provided by the second start terminal STV2 remains low, the eleventh transistor T11 and the fifteenth transistor T15 on the right side can be turned on, thereby connecting the first power supply terminal V1 to the eighth node N8, and connecting the second power supply terminal V2 to the eleventh node N11. Furthermore, when the potential of the first scan signal is low, both the first transistor T1 and the fifth transistor T5 on the left side can be turned on, thereby controlling the first selection terminal IS1 to conduct with the first node N1, and the second selection terminal IS2 to conduct with the fourth node N4. In this way, the first selection signal provided by the first selection terminal IS1 can be transmitted to the first node N1 via the turned-on first transistor T1, and the second selection signal provided by the second selection terminal IS2 can be transmitted to the fourth node N4 via the turned-on fifth transistor T5. This achieves the writing of the first selection signal to the first capacitor C1 and the writing of the second selection signal to the second capacitor C2.

[0298] Based on this, when the potential of the first selection signal is high and the potential of the second selection signal is low, the second transistor T2 on the left side can be further turned off, and the sixth transistor T6 on the left side can be further turned on. This allows the second node N2 to be disconnected from the third node N3, and the fifth node N5 to be connected to the sixth node N6. Then, when entering a holding frame, the potential of the first start signal provided by the first start terminal STV1 jumps to a low level. When the third transistor T3 and the seventh transistor T7 on the left side are turned on, the first power supply terminal V1 can be connected to the second node N2, and the second power supply terminal V2 can be connected to the fifth node N5. Because the sixth transistor T6 is turned on, the second power supply terminal V2 can be further connected to the first output terminal OUT1. The low-potential second power signal provided by the second power supply terminal V2 is then transmitted sequentially to the first output terminal OUT1 via the turned-on seventh transistor T7 and sixth transistor T6. That is, a low-level light-emitting control signal is transmitted via the first output terminal OUT1 to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. Furthermore, because the second transistor T2 is turned off, the first power supply terminal V1 can be further disconnected from the first output terminal OUT1. Therefore, based on the transmission of the low-level light-emitting control signal to the shared light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_1 shown is turned on, thereby driving the shared light-emitting element L1 to emit light. Based on transmitting a low-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_2 shown is turned on, thereby driving the privacy light-emitting element L1 to emit privacy light.

[0299] Conversely, when the second selection signal is at a high potential and the first selection signal is at a low potential, the sixth transistor T6 on the left side can be further turned off, and the second transistor T2 on the left side can be further turned on. This allows the second node N2 to be connected to the third node N3, and the fifth node N5 to be disconnected from the sixth node N6. Afterwards, when entering a holding frame, the potential of the first start signal provided by the first start terminal STV1 jumps to a low potential, turning on the third transistor T3 and the seventh transistor T7 on the left side. This allows the first power supply terminal V1 to be connected to the second node N2, and the second power supply terminal V2 to be connected to the fifth node N5. Because the second transistor T2 is turned on, the first power supply terminal V1 can be further connected to the first output terminal OUT1. The high-potential first power signal provided by the first power supply terminal V1 is then transmitted sequentially to the first output terminal OUT1 via the turned-on third transistor T3 and second transistor T2. That is, a high-potential light-emitting control signal is transmitted via the first output terminal OUT1 to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. Furthermore, because the second transistor T2 is turned off, the first power supply terminal V1 can be further disconnected from the first output terminal OUT1. Therefore, based on the transmission of the high-potential light-emitting control signal to the shared light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_1 shown is turned off, thereby stopping the shared light-emitting element L1 from emitting light. Based on transmitting a high-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_2 shown is turned off, thereby stopping the privacy light-emitting element L1 from emitting light.

[0300] Thus, by configuring the corresponding output control circuit 03 connected to the shared light-emitting control terminal EM and the corresponding output control circuit 03 connected to the privacy light-emitting control terminal EM, the shared display driver or the privacy display driver can be implemented. For example, in shared mode, the output control circuit 03 connected to the shared light-emitting control terminal EM can be configured to transmit a low-potential light-emitting control signal to the shared light-emitting control terminal EM, while the output control circuit 03 connected to the privacy light-emitting control terminal EM can be configured to transmit a high-potential light-emitting control signal to the privacy light-emitting control terminal EM, thereby controlling the display. Figure 4 The transistor M8_1 shown is turned on, and simultaneously controls the following... Figure 4Transistor M8_2 is turned off to drive the shared light-emitting element L1 to emit light, and to stop driving the privacy light-emitting element L1 to emit light, thus reliably realizing shared display. Conversely, in privacy mode, the output control circuit 03 connected to the privacy light-emitting control terminal EM can be set to transmit a low-potential light-emitting control signal to the privacy light-emitting control terminal EM, while the output control circuit 03 connected to the shared light-emitting control terminal EM can be set to transmit a high-potential light-emitting control signal to the shared light-emitting control terminal EM, thereby controlling the display as shown. Figure 4 The transistor M8_1 shown is turned off, and at the same time, it controls the following: Figure 4 The transistor M8_2 shown is turned on to drive the privacy light-emitting element L1 to emit light for privacy, and stops driving the shared light-emitting element L1 to emit light for shared light, thus reliably realizing privacy display.

[0301] During the hold frame, because the potential of the first scan signal remains high, the first transistor T1 and the fifth transistor T5 on the left side can be kept off, thereby disconnecting the first selection terminal IS1 from the first node N1 and the second selection terminal IS2 from the fourth node N4. Because the potential of the first start signal provided by the first start terminal STV1 remains high, the third transistor T3 and the seventh transistor T7 on the left side can be turned off, thereby disconnecting the first power supply terminal V1 from the second node N2 and the second power supply terminal V2 from the fifth node N5. Because the potential of the second start signal provided by the second start terminal STV2 remains low, the eleventh transistor T11 and the fifteenth transistor T15 on the right side can be turned on, thereby connecting the first power supply terminal V1 to the eighth node N8 and the second power supply terminal V2 to the eleventh node N11. Furthermore, when the potential of the second scan signal is low, both the ninth transistor T9 and the thirteenth transistor T13 on the right side can be turned on, thereby controlling the first start terminal IS1 to conduct with the seventh node N7, and the second start terminal IS2 to conduct with the tenth node N10. In this way, the first selection signal provided by the first selection terminal IS1 can be transmitted to the seventh node N7 via the turned-on ninth transistor T9, and the second selection signal provided by the second selection terminal IS2 can be transmitted to the tenth node N10 via the turned-on thirteenth transistor T13. This achieves the writing of the first selection signal to the third capacitor C3 and the writing of the second selection signal to the fourth capacitor C4.

[0302] Based on this, similarly, when the potential of the first selection signal is high and the potential of the second selection signal is low, the tenth transistor T10 on the right side can be further controlled to turn off, and the fourteenth transistor T14 on the right side can be further controlled to turn on. This allows the eighth node N8 to disconnect from the ninth node N9, and the eleventh node N11 to conduct from the twelfth node N12. Then, when entering the next refresh frame, the potential of the second start signal provided by the second start terminal STV2 jumps to low, controlling the eleventh transistor T11 and the fifteenth transistor T15 on the right side to turn on. This allows the first power supply terminal V1 to conduct from the eighth node N8, and the second power supply terminal V2 to conduct from the eleventh node N11. Because the fourteenth transistor T14 is on, the second power supply terminal V2 can be further controlled to conduct from the second output terminal OUT2. The low-potential second power signal provided by the second power supply terminal V2 is then transmitted sequentially to the second output terminal OUT2 via the turned-on fifteenth transistor T15 and fourteenth transistor T14. That is, a low-level light-emitting control signal is transmitted via the second output terminal OUT2 to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. Furthermore, because the tenth transistor T10 is turned off, the first power supply terminal V1 can be further disconnected from the second output terminal OUT2. Therefore, based on the transmission of the low-level light-emitting control signal to the shared light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_1 shown is turned on, thereby driving the shared light-emitting element L1 to emit light. Based on transmitting a low-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_2 shown is turned on, thereby driving the privacy light-emitting element L1 to emit privacy light.

[0303] Conversely, when the second selection signal is at a high potential and the first selection signal is at a low potential, the fourteenth transistor T14 on the right side can be further turned off, and the tenth transistor T10 on the right side can be further turned on. This allows the eighth node N8 and the ninth node N9 to be connected, while the eleventh node N11 and the twelfth node N12 can be disconnected. Then, when the next refresh frame is entered, the potential of the second start signal provided by the second start terminal STV2 jumps to a low potential, turning on the eleventh transistor T11 and the fifteenth transistor T15 on the right side. This allows the first power supply terminal V1 to be connected to the eighth node N8, and the second power supply terminal V2 to be connected to the eleventh node N11. Because the tenth transistor T10 is turned on, the first power supply terminal V1 can be further connected to the second output terminal OUT2. The high-potential first power signal provided by the first power supply terminal V1 is then transmitted sequentially to the second output terminal OUT2 via the turned-on eleventh transistor T11 and tenth transistor T10. That is, a high-potential light-emitting control signal is transmitted via the second output terminal OUT2 to the shared light-emitting control terminal EM or the privacy light-emitting control terminal EM connected to the output control terminal OUT_EM. Furthermore, because the fourteenth transistor T14 is turned off, the second power supply terminal V2 can be further disconnected from the second output terminal OUT2. Therefore, based on the transmission of a high-potential light-emitting control signal to the shared light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_1 shown is turned off, thereby stopping the shared light-emitting element L1 from emitting light. Based on transmitting a high-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_2 shown is turned off, thereby stopping the privacy light-emitting element L1 from emitting light.

[0304] Similarly, by configuring the corresponding output control circuit 03 connected to the shared light-emitting control terminal EM and the corresponding output control circuit 03 connected to the privacy-proof light-emitting control terminal EM, the shared display driver or the privacy-proof display driver can be achieved. This will not be elaborated further here.

[0305] Understandable, Figure 45 The timing shown is relative to Figure 44 In terms of the timing shown, the refresh frame and the hold frame are exactly swapped, and the working principle is the same, so it will not be repeated. Combined with... Figure 44 and Figure 45 As can be seen, refresh frames and hold frames complement each other to complete the overall output. Figure 44 and Figure 45 Taking the timing sequence shown as an example, Figure 46 A timing simulation diagram is also schematically shown. Combined with... Figure 46It can be seen that the scanning drive unit of this scheme can stably output a high-potential light-emitting control signal or a low-potential light-emitting control signal to both the shared light-emitting control terminal EM and the privacy light-emitting control terminal EM based on the potential difference between the first selection signal and the second selection signal. Figure 36 and Figure 37 The structural working principle of the scheme shown is the same, and will not be repeated here.

[0306] Finally, based on the above introduction to the working principle of the GOA unit, with Figure 39 The alternative structure shown uses P-type transistors with a low active potential and a high inactive potential. For example, the first power supply terminal V1 provides a high potential for the first power signal, while the second power supply terminal V2 provides a low potential for the second power signal. Figure 47 A timing diagram of another output control circuit 03 is shown. (Combined with...) Figure 47 The working principle of the output control circuit 03 of the other scheme is explained as follows: Taking column-by-column driving as an example, in each refresh frame, the potential of the scan signal provided by the shared scan terminal Scan sequentially jumps to a low potential. Figure 47 The diagram schematically illustrates the scan signals provided by n scan terminals, labeled Scan_1 to Scan_n, where n is an integer greater than 1. Furthermore, it can be deduced that an n-stage shared first shift circuit 01 and second shift circuit 02 are required. Additionally, considering... Figure 47 It can also be seen that in each refresh frame, the starting signal provided by the shared start terminal STV is at a high potential, while in the blanking region between adjacent refresh frames, the starting signal provided by the shared start terminal STV becomes at a low potential. Furthermore, in each refresh frame, the first selection signal provided by the first selection terminal IS1 consists of sequentially transitioning high and low potentials, and the second selection signal provided by the second selection terminal IS2 consists of sequentially transitioning low and high potentials.

[0307] Based on this, combine Figure 39It can be seen that, for example, in the first refresh frame, the potential of the start signal provided by the start terminal STV is high. Therefore, the shared fourth transistor T4 and eighth transistor T8, as well as the shared twelfth transistor T12 and sixteenth transistor T16, can be turned off. This allows the third node N3 to be disconnected from the first output terminal OUT1, the sixth node N6 to be disconnected from the first output terminal OUT1, the ninth node N9 to be disconnected from the second output terminal OUT2, and the twelfth node N12 to be disconnected from the second output terminal OUT2. Furthermore, when the potential of the scan signal provided by the scan terminal Scan_1 is low, the first transistor T1, the fifth transistor T5, the ninth transistor T9, and the thirteenth transistor T13 can be turned on. This allows the first selection terminal IS1 to be turned on by the first node N1 and the seventh node N7, and the second selection terminal IS2 to be turned on by the fourth node N4 and the tenth node N10. In this way, the first selection signal provided by the first selection terminal IS1 can be transmitted to the first node N1 via the turned-on first transistor T1 and to the seventh node N7 via the turned-on ninth transistor T9. Similarly, the second selection signal provided by the second selection terminal IS2 can be transmitted to the fourth node N4 via the turned-on fifth transistor T5 and to the tenth node N10 via the turned-on thirteenth transistor T13. This achieves the writing of the first selection signal to the first capacitor C1 and the third capacitor C3, and the writing of the second selection signal to the second capacitor C2 and the fourth capacitor C4.

[0308] Based on this, when the potential of the first selection signal is high and the potential of the second selection signal is low, the second transistor T2 and the tenth transistor T10 can be further turned off, while the sixth transistor T6 and the fourteenth transistor T14 can be further turned on. This allows the first power supply terminal V1 to be disconnected from either the third node N3 or the sixth node N6, and the second power supply terminal V2 to be disconnected from either the ninth node N9 or the twelfth node N12. Furthermore, the second power supply terminal V2 can be turned on from either the third node N3 or the sixth node N6, and the first power supply terminal V1 can be turned on from either the ninth node N9 or the twelfth node N12. Subsequently, when entering the blanking region, when the potential of the start signal provided by the start terminal STV becomes low, the shared fourth transistor T4 and the eighth transistor T8 can be turned on, as can the shared twelfth transistor T12 and the sixteenth transistor T16. This allows the third node N3 or the sixth node N6 to be connected to the first output terminal OUT1, and the ninth node N9 or the twelfth node N12 to be connected to the second output terminal OUT2. Furthermore, it allows the second power supply terminal V2 to be connected to the first output terminal OUT1, and the first power supply terminal V1 to be connected to the second output terminal OUT2. This enables the low-potential second power signal provided by the second power supply terminal V2 to be transmitted sequentially through the activated sixth transistor T6, and the shared fourth transistor T4 and eighth transistor T8 to the first output terminal OUT1. Conversely, it enables the high-potential first power signal provided by the first power supply terminal V1 to be transmitted sequentially through the activated fourteenth transistor T14, and the shared twelfth transistor T12 and sixteenth transistor T16 to the second output terminal OUT2. This achieves the writing of the low-potential second power signal to the fifth capacitor C5 and the writing of the high-potential first power signal to the sixth capacitor C6.

[0309] Furthermore, the seventeenth transistor T17 can be turned on, while the eighteenth transistor T18 can be turned off. This allows the first power supply terminal V1 to conduct with the output control terminal OUT_EM, and the second power supply terminal V2 to disconnect from the output control terminal OUT_EM. Furthermore, the high-potential first power signal provided by the first power supply terminal V1 can be transmitted to the output control terminal OUT_EM via the turned-on seventeenth transistor T17, and then transmitted via OUT_EM to the corresponding connected shared light-emitting control terminal EM or privacy-protected light-emitting control terminal EM. Thus, based on the transmission of the high-potential light-emitting control signal to the shared light-emitting control terminal EM, it is possible to... Figure 4 The transistor M8_1 shown is turned off, thereby stopping the shared light-emitting element L1 from emitting light. Based on transmitting a high-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4The transistor M8_2 shown is turned off, thereby stopping the privacy light-emitting element L1 from emitting light.

[0310] Conversely, when the potential of the first selection signal is low and the potential of the second selection signal is high, the second transistor T2 and the tenth transistor T10 can be further controlled to turn on, while the sixth transistor T6 and the fourteenth transistor T14 can be further controlled to turn off. This allows the first power supply terminal V1 to be connected to either the third node N3 or the sixth node N6, and the second power supply terminal V2 to be connected to either the ninth node N9 or the twelfth node N12. Furthermore, the second power supply terminal V2 can be disconnected from either the third node N3 or the sixth node N6, and the first power supply terminal V1 can be disconnected from either the ninth node N9 or the twelfth node N12. Afterwards, when entering the blanking region, when the potential of the start signal provided by the start terminal STV becomes low, the shared fourth transistor T4 and the eighth transistor T8 can be turned on, as can the shared twelfth transistor T12 and the sixteenth transistor T16. This allows the third node N3 or the sixth node N6 to be connected to the first output terminal OUT1, and the ninth node N9 or the twelfth node N12 to be connected to the second output terminal OUT2. Furthermore, it allows the first power supply terminal V1 and the second power supply terminal V2 to be connected to the first output terminal OUT1, and the second power supply terminal V2 to be connected to the second output terminal OUT2. This allows the high-potential first power signal provided by the first power supply terminal V1 to be transmitted sequentially through the activated sixth transistor T6, and the shared fourth transistor T4 and eighth transistor T8 to the first output terminal OUT1, and the low-potential second power signal provided by the second power supply terminal V2 to be transmitted sequentially through the activated fourteenth transistor T14, and the shared twelfth transistor T12 and sixteenth transistor T16 to the second output terminal OUT2. This achieves the writing of the high-potential first power signal to the fifth capacitor C5 and the writing of the low-potential second power signal to the sixth capacitor C6.

[0311] Furthermore, the seventeenth transistor T17 can be turned off, while the eighteenth transistor T18 can be turned on. This disconnects the first power supply terminal V1 from the output control terminal OUT_EM and connects the second power supply terminal V2 to the output control terminal OUT_EM. Consequently, the low-potential second power signal provided by the second power supply terminal V2 can be transmitted to the output control terminal OUT_EM via the turned-on eighteenth transistor T18. From there, a low-potential light control signal is transmitted to the corresponding connected shared light control terminal EM or privacy light control terminal EM. Thus, based on the transmission of the low-potential light control signal to the shared light control terminal EM, it is possible to achieve the following... Figure 4The transistor M8_1 shown is turned on, thereby driving the shared light-emitting element L1 to emit light. Based on transmitting a low-potential light-emitting control signal to the privacy light-emitting control terminal EM, it is possible to achieve the following: Figure 4 The transistor M8_2 shown is turned on, thereby driving the privacy light-emitting element L1 to emit privacy light.

[0312] Similarly, by configuring the corresponding output control circuit 03 connected to the shared light-emitting control terminal EM and the corresponding output control circuit 03 connected to the privacy-proof light-emitting control terminal EM, the shared display driver or the privacy-proof display driver can be achieved. This will not be elaborated further here.

[0313] It is understandable that, based on the working principle of this alternative scheme, the first scanning end Scan1 and the second scanning end Scan2 can be set to share the same space, the first starting end STV1 and the second starting end STV2 can be set to share the same space, and correspondingly, the first shift circuit 01 and the second shift circuit 02 can also be set to share the same space. Figure 47 Taking the timing sequence shown as an example, Figure 48 A timing simulation diagram is also schematically shown. Combined with... Figure 48 As can be seen, depending on the potential difference between the first selection signal and the second selection signal, the scanning drive unit of this alternative scheme can also stably output a high-potential light control signal or a low-potential light control signal to both the shared light control terminal EM and the privacy light control terminal EM. Figure 38 and Figure 40 The working principle of the other scheme shown is the same, and will not be repeated here.

[0314] Optionally, the first selection signal provided by the first selection terminal IS1, or the second selection signal provided by the second selection terminal IS2, can both be provided by the display driver IC (DDIC) in conjunction with the timing controller (TCON). For example, the DDIC can determine the positions of the privacy protection area and the shared area in the display panel based on image display data transmitted, such as from the application processor (AP), and can work with the TCON to provide the required first selection signal to the first selection terminal IS1 controlling the corresponding area, and the required second selection signal to the second selection terminal IS2 controlling the corresponding area, based on the determined positions.

[0315] It is understood that since the driving method of the scanning driving unit can have the same technical effect as the scanning driving unit described in the previous embodiments, the technical effect of the driving method of the scanning driving unit will not be described again here for the purpose of brevity.

[0316] This application also provides a scanning drive circuit. For example... Figure 49 and Figure 50 As shown, the scan drive circuit includes: a plurality of cascaded scan drive units 00 as described above.

[0317] Combination Figure 49 In each scanning drive unit 00, the first shift circuit 01 is connected to the input signal terminal IN of the first shift circuit 01 in the cascaded scanning drive unit 00 via the output signal terminal OUT, and in each scanning drive unit 00, the second shift circuit 02 is connected to the input signal terminal IN of the second shift circuit 02 in the cascaded scanning drive unit 00 via the output signal terminal OUT. Furthermore, in each scanning drive unit 00, the first shift circuit 01 is connected to the first scanning terminal Scan1 of the output control circuit 03 via the output signal terminal OUT, and the second shift circuit 02 is connected to the second scanning terminal Scan2 of the output control circuit 03 via the output signal terminal OUT.

[0318] For example, with the above Figures 35 to 37 Taking one of the solutions shown as an example, refer to Figure 49 The first shift circuit 01 is designated as GOA1, and the second shift circuit 02 is designated as GOA2. In the first-level scan drive unit 00, the output signal terminal OUT of the first shift circuit GOA1 (1) is connected to the first scan terminal Scan1 of the output control circuit 03 (1), and is also connected to the input signal terminal IN of the first shift circuit GOA1 (2) in the second-level scan drive unit 00. The output signal terminal OUT of the second shift circuit GOA2 (1) is connected to the second scan terminal Scan2 of the output control circuit 03 (1), and is also connected to the input signal terminal IN of the second shift circuit GOA2 (2) in the second-level scan drive unit 00. And so on. Of course, in the first-level scan drive unit 00, the input signal terminal IN of the first shift circuit GOA1 (1) is also connected to the start signal terminal STV01, and the input signal terminal IN of the second shift circuit GOA2 (1) is also connected to the start signal terminal STV02. Furthermore, in each scanning drive unit 00, the first shift circuit GOA1 and the second shift circuit GOA2 are also connected to other signal terminals such as the pull-up power supply terminal VGH, the pull-down power supply terminal VGL, the first clock terminal CK, and the second clock terminal CB; the output control circuit 03 is also connected to the pull-up power supply terminal VGH, the pull-down power supply terminal VGL, the first selection terminal IS1, the second selection terminal IS2, the first start terminal STV1, and the second start terminal STV2. Optionally, in some embodiments, the first start terminal STV1 can be shared with the start signal terminal STV01 as the same signal terminal; the second start terminal STV2 can be shared with the start signal terminal STV02 as the same signal terminal.

[0319] For example, using the above... Figures 38 to 40 Another solution shown is illustrated below, for reference. Figure 50 The shared first shift circuit 01 and second shift circuit 02 are designated as shift circuit GOA, the shared first scan terminal Scan1 and second scan terminal Scan2 are designated as scan terminal Scan, and the shared first start terminal STV1 and second start terminal STV2 are designated as start terminal STV. In the first-level scan drive unit 00, the output signal terminal OUT of shift circuit GOA (1) is connected to the scan terminal Scan in the output control circuit 03 (1), and is also connected to the input signal terminal IN of shift circuit GOA (2) in the second-level scan drive unit 00. And so on. Of course, in the first-level scan drive unit 00, the input signal terminal IN of shift circuit GOA (1) is also connected to the start signal terminal STV0. Furthermore, in each scan drive unit 00, the shift circuit GOA is also connected to other signal terminals such as the pull-up power supply terminal VGH, the pull-down power supply terminal VGL, the first clock terminal CK, and the second clock terminal CB; the output control circuit 03 is also connected to the pull-up power supply terminal VGH, the pull-down power supply terminal VGL, the first selection terminal IS1, the second selection terminal IS2, and the start terminal STV. Optionally, in some embodiments, the start terminal STV can be shared with the start signal terminal STV0 as the same signal terminal.

[0320] Understandable, Figure 49 and Figure 50 Each scan drive unit 00 schematically illustrates an output control circuit 03, which is actually combined with... Figure 5 It is understood that each scanning drive unit 00 needs to include two identical output control circuits 03, which are respectively connected to the shared light emission control terminal EM and the privacy light emission control terminal EM. The architecture and working principle of the two output control circuits 03 are the same, and will not be described again.

[0321] Optionally, combined Figure 49 and Figure 50 It is also known that the first-level scanning drive unit 00 shown can correspond to the first column of pixels, that is, each output control circuit 03(1) can be connected to the first column of pixels via a shared light-emitting control terminal EM or a privacy light-emitting control terminal EM. The second-level scanning drive unit 00 can correspond to the second column of pixels, that is, each output control circuit 03(1) can be connected to the second column of pixels via a shared light-emitting control terminal EM or a privacy light-emitting control terminal EM. And so on, without showing them one by one. Of course, it is not limited to this. For example, each level of scanning drive unit 00 can also be connected to a row of pixels. For example, each level of scanning drive unit 00 can also be connected to multiple rows of pixels or multiple columns of pixels.

[0322] Optionally, in the embodiments of this application, the first shift circuit 01, the second shift circuit 02, the output control circuit 03, and other circuits can all be integrated into the display panel according to the Gate Driver in Active Area (GIAA) design, or they can be set at any position on the bezel of the display panel as needed. Among them, the GIAA layout can facilitate narrow bezel design.

[0323] It is understood that since the scan driving circuit can have essentially the same technical effect as the scan driving unit described in the previous embodiments, the technical effect of the scan driving circuit will not be described again here for the sake of brevity.

[0324] This application also provides a display device. For example... Figure 51 As shown, the display device includes a display panel 100 and a scan drive circuit 000 as described above. The display panel 100 includes a plurality of pixels.

[0325] Combination Figure 5 In the scanning drive circuit 000, each scanning drive unit 00 includes two output control circuits 03 that are respectively connected to the shared light emission control terminal EM and the privacy light emission control terminal EM of the same pixel. They are used to transmit a shared light emission control signal to the shared light emission control terminal EM to drive the shared light emission element L1 in the pixel to emit light together, and to transmit a privacy light emission control signal to the privacy light emission control terminal EM to drive the privacy light emission element L1 in the pixel to emit light in a privacy manner.

[0326] Optionally, Figure 51 In the scan drive circuit 000 shown, each scan drive unit 00 is connected to each column of pixels in a one-to-one correspondence; however, this is not the only possibility. For example, as described above, each scan drive unit 00 can also be connected to each row of pixels in a one-to-one correspondence. Furthermore, Figure 51 The diagram schematically shows m columns of pixels. Scan drive unit 00 (1) represents the scan drive unit 00 corresponding to the first column of pixels. Scan drive unit 00 (m) represents the scan drive unit 00 corresponding to the m-th column of pixels.

[0327] Optionally, for a display panel that divides a shared area and a privacy protection area, a multi-level scanning drive unit 00, including the scanning drive circuit 000, can be integrated at the upper or lower edge of the display panel 100. This allows for column-by-column control of the shared light-emitting element L1 and the privacy-protecting light-emitting element L1 in the pixels, enabling free switching between the privacy-protecting and shared positions. However, this is not the only option. For example, the multi-level scanning drive unit 00, including the scanning drive circuit 000, can also be integrated at the left or right edge of the display panel 100 to row-by-row control of the shared light-emitting element L1 and the privacy-protecting light-emitting element L1 in the pixels.

[0328] For example, a multi-level scan drive unit 00 is set on the upper border, and as described above... Figures 35 to 37 Taking one of the solutions shown as an example, refer to Figure 52 It can be seen that, based on this scheme, each scanning drive unit 00 can be configured to include a first shift circuit 01 and a second shift circuit 02, to provide a first scanning signal to the first scanning end Scan1 and a second scanning signal to the second scanning end Scan2, respectively. Correspondingly, Figure 52 In the document, the first shift circuit 01 is designated Scan1-GOA, and the second shift circuit 02 is designated Scan2-GOA. Furthermore, Figure 52 The diagram also schematically illustrates that in each scanning drive unit 00, there is an output control circuit 03 (labeled 03-shared) connected to the shared light emission control terminal EM, and another output control circuit 03 (labeled 03-peeping) connected to the privacy light emission control terminal EM. Scan1-GOA is connected to both 03-shared and 03-peeping, forming the first scanning terminal Scan1; Scan2-GOA is connected to both 03-shared and 03-peeping, forming the second scanning terminal Scan2. Optionally, in conjunction with... Figure 52 It can also be seen that Scan1-GOA and Scan2-GOA can be arranged sequentially along the pixel row direction; 03-Shared and 03-Peeping Protection can be arranged sequentially along the pixel row direction; while Scan1-GOA and 03-Shared can be arranged sequentially along the pixel column direction, and Scan2-GOA and 03-Peeping Protection can be arranged sequentially along the pixel column direction. This facilitates layout. Of course, it is not limited to this.

[0329] Based on the above Figures 38 to 40 Another solution shown is illustrated below, for reference. Figure 53 As can be seen, based on this alternative scheme, the following settings can be configured: Figure 52 The first shift circuit 01 and the second shift circuit 02 shown share the same shift circuit to provide the same scan signal to the shared first scan terminal Scan1 and second scan terminal Scan2 (i.e., the scan terminal Scan). Accordingly, Figure 53In this designation, the shared first shift circuit 01 and second shift circuit 02 are designated as Scan-GOA. Furthermore, Figure 53 The diagram also schematically illustrates that in each scanning drive unit 00, there is an output control circuit 03 (labeled 03-shared) connected to the shared light emission control terminal EM, and another output control circuit 03 (labeled 03-peeping) connected to the privacy light emission control terminal EM. Scan-GOA is connected to both the 03-shared and 03-peeping scanning terminals Scan. Optionally, in conjunction with... Figure 53 It can also be seen that Scan-GOA, 03-Shared, and 03-Peeping Protection can be arranged sequentially along the pixel column direction. This facilitates layout. Of course, it is not limited to this.
