[0066] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0067] It is understood that the transistors used in all embodiments of this application can be thin-film transistors, field-effect transistors, or other devices with similar characteristics. Based on their function in the circuit, the transistors used in the embodiments of this application are mainly switching transistors. Since the source and drain of the switching transistors used here are symmetrical, their source and drain are interchangeable. In the embodiments of this application, the source is referred to as the first electrode, and the drain as the second electrode. According to the configuration shown in the accompanying drawings, the middle terminal of the transistor is the control electrode, also called the gate; the signal input terminal is the source; and the signal output terminal is the drain. Furthermore, the switching transistors used in the embodiments of this application can include either P-type or N-type switching transistors. A P-type switching transistor conducts when the gate is at a low potential and is cut off when the gate is at a high potential; an N-type switching transistor conducts when the gate is at a high potential and is cut off when the gate is at a low potential. In addition, multiple signals in various embodiments of this application correspond to a first potential and a second potential. The first potential and the second potential only represent that the potential of the signal has two states and do not represent that the first potential or the second potential has a specific value throughout the text.

[0068] The privacy pixel side typically features a black matrix (BM) shielding layer and a lens structure. This BM shielding layer and lens block and converge the light emitted by the privacy pixel from a wide viewing angle, allowing it to emit light from a narrow viewing angle. The shared pixel side generally does not have a BM shielding layer, or the BM shielding layer is sufficiently far away from the shared pixel to avoid affecting its wide-viewing-angle light emission, thus allowing the shared pixel to emit light from a wide viewing angle. Based on this structure, the display panel can share or not share the displayed information at different viewing angles, meeting users' needs for privacy protection and information sharing. However, currently, sharing or not sharing can only be achieved through the structure itself at different viewing angles, resulting in poor display flexibility. Therefore, this application provides a novel display panel that can achieve sharing and privacy protection through circuit control, and the proportion of the shared and privacy-protected portions can be arbitrarily set, offering better display flexibility.

[0069] Figure 1 is a schematic diagram of a display panel provided in an embodiment of this application. As shown in Figure 1, the display panel includes:

[0070] Substrate 01.

[0071] Multiple pixels 02 are located on substrate 01, at least two pixels 02 including a privacy pixel and a shared pixel. For example, in some embodiments, each pixel 02 may include a privacy pixel and a shared pixel. That is, a pixel can be divided into two parts: a privacy pixel and a shared pixel. Each part includes the same pixel circuit, and the light-emitting device included in the privacy pixel is a privacy light-emitting device with a small viewing angle to achieve the privacy function and prevent the leakage of display information. The light-emitting device included in the shared pixel is a shared light-emitting device with a large viewing angle to achieve the sharing function and ensure the sharing of display information.

[0072] For example, referring to Figures 1 and 2, in some embodiments, each pixel can be divided into a privacy pixel and a shared pixel arranged in columns. For a large pixel unit including red (R) pixels, green (G) pixels, and blue (B) pixels, the RGB can be arranged sequentially along the row direction X1, and the privacy pixel and shared pixel included in each RGB can be arranged sequentially along the column direction Y1. The row direction X1 and the column direction Y1 can intersect, such as being perpendicular to each other as shown in Figure 2. For distinction, in Figure 2, the privacy pixel and shared pixel included in the red pixel R are labeled R-privacy and R-shared, respectively; the privacy pixel and shared pixel included in the green pixel G are labeled G-privacy and G-shared, respectively; and the privacy pixel and shared pixel included in the blue pixel B are labeled B-privacy and B-shared, respectively. Thus, it can be seen that the pixel circuits included in odd-numbered rows of pixels can drive the privacy pixel to emit light; the pixel circuits included in even-numbered rows of pixels can drive the shared pixel to emit light. That is, pixels in odd-numbered rows can be called privacy pixels; pixels in even-numbered rows can be called shared pixels. Of course, this is only an illustrative example of one arrangement, and any possible arrangement can be applied to this application. For example, in some other embodiments, each pixel can also be divided into a privacy pixel and a shared pixel arranged in rows.

[0073] Optionally, taking an organic light-emitting diode (OLED) as the light-emitting device as an example, Figure 3 shows a schematic diagram of the circuit structure of a privacy pixel and a shared pixel in a pixel. Referring to Figure 3, it can be seen that both the privacy pixel and the shared pixel in a pixel can include the same 9T1C (9 transistors T01 to T09, and 1 capacitor C) pixel circuit structure, and the light-emitting device connected to the pixel circuit in the privacy pixel can be a privacy OLED, while the light-emitting device connected to the pixel circuit in the shared pixel can be a shared OLED.

[0074] Optionally, as can be seen from the foregoing description and Figure 4, a privacy OLED can refer to a structure with a shielding layer on top of the OLED, allowing the privacy OLED to emit light from a narrow viewing angle under the shielding layer. A shared OLED can refer to a structure without a shielding layer on top of the OLED, allowing the shared OLED to emit light from a wide viewing angle. The shielding layer can be, for example, the BM shielding layer shown in Figure 4, or a metal layer with poor light transmittance. This application does not limit the choice of shielding layer. Of course, the pixel circuit structure shown in Figure 3 and the OLED device structure shown in Figure 4 are merely illustrative, and any possible structure can be applied in this application.

[0075] Optionally, the pixels, including privacy pixels and shared pixels, can be applied to display panels in various scenarios, such as in automotive displays. This allows the automotive display to have at least two display modes: 1. Shared mode full-screen wide-viewing-angle display; 2. Partial privacy display, i.e., wide-viewing-angle display of a portion of the display screen. This allows, for example, the screen closer to the driver's side to share display information, while ensuring that the screen closer to the passenger's side displays privacy information without affecting the driver's driving, thus ensuring driving safety. Of course, its application is not limited to automotive scenarios. For example, it can also be applied to display products used by some confidential units, such as mobile phones, laptops (notebooks, NBs), or tablets. Based on the above example, referring to Figure 5, the display panel also includes:

[0076] The first light-emitting driving circuit 03, located on the substrate 01, is used to control the light-emitting state of the corresponding privacy pixel. That is, the first light-emitting driving circuit 03 can drive the privacy pixel in one pixel to emit light. Furthermore, the first light-emitting driving circuit 03 can be integrated on the substrate using gate driver on array (GOA) technology, and is also called a GOA circuit.

[0077] The second light-emitting driving circuit 04, located on the substrate 01, is used to control the light-emitting state of the corresponding shared pixel. That is, the second light-emitting driving circuit 04 can drive the shared pixel in a pixel to emit light. Furthermore, this second light-emitting driving circuit 04 can also be integrated on the substrate using GOA technology, and is also called a GOA circuit.

[0078] Each of the first light-emitting driving circuit 03 and the second light-emitting driving circuit 04 includes a light-emitting driving module 001 and a light-emitting control module 002. The output terminal OUT of the light-emitting driving module 001 is connected to the light-emitting control module 002, and the output terminal EOUT of the light-emitting control module 002 is connected to the corresponding pixel. The light-emitting control module 002 is also connected to the enable terminal EN and the switch terminal K. That is, different light-emitting driving circuits that drive the privacy pixel and the shared pixel to emit light can all include a light-emitting driving module 001 and a light-emitting control module 002, and the light-emitting driving module 001 can be indirectly connected to the corresponding pixel through the light-emitting control module 002, rather than directly.

[0079] It is understandable that for the first light-emitting driving circuit 03 that drives the privacy pixel to emit light, the pixel (that is, the corresponding pixel) connected to the output terminal of its light-emitting control module 002 is the privacy pixel; for the second light-emitting driving circuit 04 that drives the shared pixel, the pixel (that is, the corresponding pixel) connected to the output terminal of its light-emitting control module 002 is the shared pixel.

[0080] Furthermore, the light-emitting driving module 001 is used to output a light-emitting driving signal, and the light-emitting control module 002 is used to output the light-emitting driving signal to the connected pixel to control the connected pixel to emit light, or to output a shutdown signal to control the connected pixel not to emit light, based on the light-emitting driving signal, the enable signal provided by the enable terminal EN and the switch signal provided by the switch terminal K.

[0081] That is, the light-emitting driving module 001 can be the part that generates and outputs the light-emitting driving signal, while the light-emitting control module 002 can be the part that controls whether the light-emitting driving signal is transmitted to the pixel. For example, the light-emitting control module 002 can control the light-emitting driving signal output by the light-emitting driving module 001 through the output terminal OUT to be further transmitted to the pixel, that is, output a normal light-emitting driving signal to the pixel to control the pixel to emit light; or, the light-emitting control module 002 can also control the light-emitting driving signal output by the light-emitting driving module 001 through the output terminal OUT to be unable to be transmitted to the pixel, but instead output a shutdown signal to the pixel to control the pixel not to emit light.

[0082] Referring to Figure 3, the light-emitting driving module 001 can be connected to the light-emitting control terminal EM of the pixel circuit via the light-emitting control module 002, so as to output the aforementioned light-emitting driving signal or off signal to the light-emitting control terminal EM, thereby controlling the pixel to emit light or not emit light. Optionally, the light-emitting driving signal can be a pulse signal with high potential and low potential, and the off signal can be a DC signal with a continuous high potential or low potential. The light-emitting driving signal can be used to control the normal switching of the transistor (e.g., T07) connected to the light-emitting control terminal EM in the pixel circuit. When T07 is turned on, a loop can be formed between the pull-up power supply terminal ELVDD and the pull-down power supply terminal ELVSS, so that the light-emitting device in the pixel can emit light. The off signal can be used to control the transistor connected to the light-emitting control terminal EM in the pixel circuit to remain in the off state, so that the light-emitting device in the pixel remains in the non-emitting state. Accordingly, in the embodiments of this application, the light-emitting driving module 001 can also be referred to as the EM circuit or the EM GOA circuit, and the light-emitting control module 002 can be referred to as the EN control circuit of the EN GOA circuit.

[0083] For example, referring to Figure 5, in the first light-emitting driving circuit 03, the light-emitting driving module 001 can output a light-emitting driving signal to drive the privacy pixel to emit light via the output terminal OUT. The light-emitting control module 002 can, under the control of multiple signals such as an enable signal, a switch signal, and the light-emitting driving signal, control the light-emitting driving signal to further transmit to the privacy pixel to control the privacy pixel to emit light, or directly output a shutdown signal to the privacy pixel to control the privacy pixel not to emit light. Similarly, in the second light-emitting driving circuit 04, the light-emitting driving module 001 can output a light-emitting driving signal to drive the shared pixel to emit light via the output terminal OUT. The light-emitting control module 002 can, under the control of multiple signals such as an enable signal, a switch signal, and the light-emitting driving signal, control the light-emitting driving signal to further transmit to the shared pixel to control the shared pixel to emit light, or directly output a shutdown signal to the privacy pixel to control the shared pixel not to emit light. Therefore, by flexibly setting the enable signal, it is possible to flexibly control whether the privacy pixel emits light or not, and to control whether the shared pixel emits light or not. In the sharing mode, it is possible to control only the shared pixel to emit light while controlling the privacy pixel to not emit light, or to control both the shared pixel and the privacy pixel to emit light. In the privacy mode, it is possible to control only some or all of the privacy pixels to emit light while controlling the shared pixel to not emit light.

[0084] For example, taking the first light-emitting driving circuit 03 controlling the privacy pixel as an example, when the enable signal provided by the enable terminal EN is at the first potential, the light-emitting control module 002 can control the light-emitting driving signal output by the light-emitting driving module 001 to be further transmitted to the privacy pixel to control the privacy pixel to emit light. When the enable signal provided by the enable terminal EN is at the second potential, the light-emitting control module 002 can directly transmit a shutdown signal to the privacy pixel to control the privacy pixel not to emit light. The second light-emitting driving circuit 04 controls the shared pixel in the same way. Optionally, in the embodiments of this application, the first potential can be a low potential relative to the second potential. Of course, in some other embodiments, the first potential can also be a high potential relative to the second potential.

[0085] Based on this, it can also be understood that, to flexibly accommodate the sharing mode and the privacy module, the enable terminal EN connected to the light-emitting control module 002 in the first light-emitting driving circuit 03 and the second light-emitting driving circuit 04 should be different enable terminals. Assuming that the enable terminal EN connected to the light-emitting control module 002 in the first light-emitting driving circuit 03 is labeled EN1, and the enable terminal EN connected to the light-emitting control module 002 in the second light-emitting driving circuit 04 is labeled EN2, then it can be concluded that:

[0086] In shared mode, the enable signal provided by enable terminal EN1 can be set to a second potential, and the enable signal provided by enable terminal EN2 can be set to a first potential. This causes the light-emitting control module 002 in the first light-emitting drive circuit 03 to respond to the enable signal at the second potential by transmitting a shutdown signal to the privacy pixel to control it from emitting light. Simultaneously, the light-emitting control module 002 in the second light-emitting drive circuit 04, responding to the enable signal at the first potential, further transmits the light-emitting drive signal output by the light-emitting drive module 001 to the shared pixel to control it from emitting light. Thus, in shared mode, only the shared pixel is controlled to emit light, while the privacy pixel is controlled to remain off.

[0087] Alternatively, in shared mode, the potentials of the enable signals provided by enable terminal EN1 and enable terminal EN2 can both be set to a first potential. This causes the light-emitting control module 002 in the first light-emitting drive circuit 03 to respond to the first potential enable signal and further transmit the light-emitting drive signal output by the light-emitting drive module 001 to the privacy pixel to control its light emission. Simultaneously, the light-emitting control module 002 in the second light-emitting drive circuit 04, also responding to the first potential enable signal, further transmits the light-emitting drive signal output by the light-emitting drive module 001 to the shared pixel to control its light emission. Thus, in shared mode, both the privacy pixel and the shared pixel can be controlled to emit light.

[0088] In privacy mode, the enable signal provided by enable terminal EN1 can be set to a first potential, and the enable signal provided by enable terminal EN2 can be set to a second potential. This causes the light-emitting control module 002 in the first light-emitting drive circuit 03 to respond to the enable signal at the first potential, further transmitting the light-emitting drive signal output by the light-emitting drive module 001 to the privacy pixel to control the privacy pixel to emit light. Conversely, the light-emitting control module 002 in the second light-emitting drive circuit 04, responding to the enable signal at the second potential, transmits a shutdown signal to the shared pixel to control the shared pixel from emitting light. Thus, in privacy mode, only the privacy pixel is controlled to emit light, while the shared pixel is controlled not to emit light.

[0089] Of course, the substrate 01 can also be divided into a privacy protection area and other areas according to the privacy protection mode and the sharing mode. By setting the enable signal as described above, the privacy protection pixels in the privacy protection area can be controlled to emit light while the sharing pixels do not emit light. At the same time, the privacy protection pixels in other areas can be controlled to not emit light while the sharing pixels emit light, or both the privacy protection pixels and the sharing pixels in other areas can be controlled to emit light, thus achieving partial privacy protection and making the ratio of sharing to privacy protection adjustable. This display panel has good display flexibility.

[0090] In summary, this application provides a display panel. The display panel includes privacy pixels and shared pixels, and the light-emitting driving circuits controlling the light emission of both the privacy pixels and shared pixels include a light-emitting driving module and a light-emitting control module. Since the light-emitting control module can selectively output a light-emitting driving signal provided by the light-emitting driving module to the connected pixel to control the pixel to emit light, or output a shutdown signal to control the pixel not to emit light, the enable signal can be flexibly set to allow flexible control of the privacy pixels' light emission in privacy mode and flexible control of the shared pixels' light emission in sharing mode, thereby meeting users' needs for privacy protection and information sharing in different scenarios.

[0091] Optionally, as can be seen from Figures 1 and 2, the plurality of pixels 02 described in the embodiments of this application can be arranged in an array, and each pixel 02 can include a privacy pixel and a shared pixel arranged in columns. That is, the display panel can include multiple rows and columns of pixels 02, and each pixel 02 can include a privacy pixel and a shared pixel arranged in the column direction Y1.

[0092] Accordingly, as shown in Figures 6 and 7, the display panel can be considered to include multiple rows of privacy pixels and multiple rows of shared pixels located on substrate 01. The odd-numbered rows of pixels shown in the figures are privacy pixels, and the even-numbered rows are shared pixels. For example, the first row (Row_1) is a privacy pixel, labeled Row_1 (privacy), the second row (Row_2) is a shared pixel, labeled Row_2 (shared), the third row (Row_3) is a privacy pixel, labeled Row_3 (privacy), the fourth row (Row_4) is a shared pixel, labeled Row_4 (shared), and so on. Also shown are the (n-3)th row privacy pixel (Row_n-3 (privacy), the (n-2)th row shared pixel (Row_n-2 (shared), the (n-1)th row privacy pixel (Row_n-1 (privacy),) and the nth row shared pixel (Row_n (shared)). Here, n is an integer greater than 1.

[0093] Based on this, the display panel may include: a plurality of first light-emitting driving circuits 03 for controlling the light-emitting state of multiple rows of privacy pixels, and a plurality of second light-emitting driving circuits 04 for controlling the light-emitting state of multiple rows of shared pixels.

[0094] Furthermore, in each of the plurality of first light-emitting driving circuits 03 and the plurality of second light-emitting driving circuits 04, the light-emitting driving module 001 can be connected to at least one row of corresponding pixels through the light-emitting control module 002.

[0095] For example, in one implementation, as shown in Figure 6, the light-emitting driving module 001 can be connected to the corresponding pixels in two adjacent rows through the light-emitting control module 002. That is, for each first light-emitting driving circuit 03, the light-emitting driving module 001 can be connected to the adjacent odd-numbered rows of privacy pixels through the light-emitting control module 002; for each second light-emitting driving circuit 04, the light-emitting driving module 001 can be connected to the adjacent even-numbered rows of shared pixels through the light-emitting control module 002. Accordingly, the display panel may include n / 2 first light-emitting driving circuits 03 and n / 2 second light-emitting driving circuits 04. Each first light-emitting driving circuit 03 is used to connect to two adjacent rows of privacy pixels, and different first light-emitting driving circuits 03 are connected to privacy pixels in different rows; each second light-emitting driving circuit 04 is used to connect to two adjacent rows of shared pixels, and different second light-emitting driving circuits 04 are connected to shared pixels in different rows.

[0096] For example, in another implementation, as shown in Figure 7, the light-emitting driving module 001 can be connected to a row of corresponding pixels through the light-emitting control module 002. That is, for each first light-emitting driving circuit 03, the light-emitting driving module 001 can be connected to a row of odd-numbered privacy pixels through the light-emitting control module 002; for each second light-emitting driving circuit 04, the light-emitting driving module 001 can be connected to a row of shared pixels through the light-emitting control module 002. Accordingly, the display panel may include n first light-emitting driving circuits 03 and n second light-emitting driving circuits 04. The multiple first light-emitting driving circuits 03 are used to connect one-to-one with multiple rows of privacy pixels; the multiple second light-emitting driving circuits 04 are used to connect one-to-one with multiple rows of privacy pixels.

[0097] Furthermore, in some embodiments, continuing to refer to Figure 7, it can be seen that when the light-emitting driving module 001 is connected to a corresponding pixel in a row through the light-emitting control module 002, the light-emitting driving modules 001 included in the first light-emitting driving circuit 03 and the second light-emitting driving circuit 04 controlling the light-emitting state of the privacy pixel and the shared pixel in the same pixel 02 can be shared. Accordingly, the display panel can still include n / 2 first light-emitting driving circuits 03 and second light-emitting driving circuits 04. In this way, the structure can be simplified, costs can be saved, and it is beneficial for narrow bezel design.

[0098] Optionally, the light-emitting driving modules 001 in the respective light-emitting driving circuits that connect pixels corresponding to different rows can be cascaded. That is, the light-emitting driving modules 001 connecting privacy pixels in different rows can be cascaded together, and the light-emitting driving modules 001 connecting shared pixels in different rows can be cascaded together. Of course, when the light-emitting driving modules 001 included in the first light-emitting driving circuit 03 and the second light-emitting driving circuit 04 are shared, the respective light-emitting driving modules 001 can be cascaded together.

[0099] To distinguish them, in Figure 6, the light-emitting driving module 001 included in the first light-emitting driving circuit 03 is labeled EM1, and the light-emitting control module 002 connected to EM1 is labeled EN1 control circuit. Similarly, the light-emitting driving module 001 included in the second light-emitting driving circuit 04 is labeled EM2, and the light-emitting control module 002 connected to EM2 is labeled EN2 control circuit. Furthermore, along the direction from the first row to the last row, the first EM1 is labeled EM11, the second EM1 is labeled EM12, and so on; EM2 is labeled similarly. In Figure 7, since EM1 and EM2 can be shared, the light-emitting driving module 001 connecting the privacy pixel and the shared pixel in a pixel is labeled EM. And along the direction from the first row to the last row, the first EM circuit is labeled EM1, the second EM circuit is labeled EM2, and so on. As described above, in Figure 6, each EM1 can be cascaded, and each EM2 can be cascaded. In Figure 7, each EM circuit can be cascaded.

[0100] Optionally, referring to Figures 6 and 7, in the embodiments of this application, two adjacent EM circuits can be cascaded step by step, so that the light-emitting driving signal can be transmitted step by step. Of course, it is not limited to step-by-step cascading. For example, the first EM circuit can be cascaded with the fourth EM circuit. The embodiments of this application do not limit the cascading method.

[0101] Optionally, referring further to Figures 6 and 7, it can be seen that the display panel described in the embodiments of this application may further include:

[0102] The display panel includes multiple gate drive circuits GT and multiple reset drive circuits RE. Each gate drive circuit GT can transmit gate drive signals to both the privacy pixel and the shared pixel belonging to a pixel, and each reset drive circuit RE can transmit gate drive signals to both the privacy pixel and the shared pixel belonging to a pixel. That is, a gate drive circuit GT can be connected to both a privacy pixel and a shared pixel belonging to a pixel. A reset drive circuit RE can be connected to both a privacy pixel and a shared pixel belonging to a pixel. In other words, the privacy pixel and the shared pixel belonging to a pixel can share a single gate drive circuit GT or a single reset drive circuit RE. Accordingly, for the structures shown in Figures 6 and 7, the display panel can include n / 2 gate drive circuits GT and n / 2 reset drive circuits RE. Alternatively, one gate drive circuit GT and / or one reset drive circuit RE can be provided for each row of privacy pixels or each row of shared pixels. Accordingly, for the structures shown in Figures 6 and 7, the display panel can include n gate drive circuits GT and n reset drive circuits RE.

[0103] To distinguish them, in Figures 6 and 7, the same gate drive circuit GT connected to the privacy pixel in the first row and the shared pixel in the second row is labeled as GT-1&2, and the same reset drive circuit RE connected to the privacy pixel in the first row and the shared pixel in the second row is labeled as RE-1&2. The other rows are labeled in the same way, and will not be described in detail again.

[0104] It is understandable that the gate drive circuit GT can directly transmit the gate drive signal to the pixel without responding to other signals to transmit the gate drive signal or the off signal to the pixel. The reset drive circuit RE works similarly. Furthermore, referring to Figure 3, the gate drive circuit GT can be connected to the gate signal terminal (Gate) of the pixel circuit to output the gate drive signal to the gate signal terminal (Gate). The reset drive circuit RE can be connected to the reset signal terminal (Reset) of the pixel circuit to output the reset drive signal to the reset signal terminal (Reset).

[0105] Optionally, referring to Figures 6 and 7, for each pixel including the privacy pixel and the shared pixel, the display panel may include: a gate driving circuit GT, a reset driving circuit RE, a first light-emitting driving circuit 03, and a second light-emitting driving circuit 04 located on each side of the substrate 01 in the row direction X1. Both the first light-emitting driving circuit 03 and the second light-emitting driving circuit 04 include an EM circuit and an EN control circuit. That is, on the left and right sides of the substrate 01, for each row of privacy pixels or shared pixels, a gate driving circuit GT, a reset driving circuit RE, a first light-emitting driving circuit 03, and a second light-emitting driving circuit 04 are provided. This reduces the influence of the load on the circuit and pixel connection lines on the signal, ensuring that each pixel on the left and right sides of the substrate 01 in each row can receive a signal with essentially the same potential, thereby improving the display uniformity of each pixel on the left and right sides of the substrate 01 and ensuring a better display effect.

[0106] For example, in the display panel shown in Figures 6 and 7, the EM circuit, EN control circuit, gate drive circuit GT, and reset drive circuit RE are arranged sequentially on the left and right sides of the substrate 01, along the direction close to the pixel. This facilitates layout.

[0107] That is, in one embodiment, as shown in FIG6, adjacent first-row privacy pixels and second-row shared pixels can be driven simultaneously by the same gate drive signal and reset drive signal, while the light-emitting drive signal can be driven separately for odd-numbered rows and even-numbered rows. Furthermore, an EN control circuit is added before both the EM1 driving the privacy pixel and the EM2 driving the shared pixel. The light-emitting drive signal is still passed step by step, while the EN control circuit can control the waveform output to the pixel, such as controlling whether the waveform output to the pixel is the normal light-emitting drive signal waveform or the off signal waveform. In another embodiment, as shown in FIG7, the design of one EM circuit connected to the pixel through one EN control circuit can also be changed to a design of one EM circuit connected to the privacy pixel and the shared pixel respectively through two EN control circuits. Of course, the arrangement shown in FIG6 and FIG7 is only illustrative, and any arrangement applicable to the embodiments of this application can be used in this application.

[0108] It is understood that the above embodiments are all illustrated using the pixel structure shown in Figure 3 as an example. In other embodiments, the privacy pixel and the shared pixel in a pixel can also share the same pixel circuit, but the privacy light-emitting device and the shared light-emitting device are controlled by different light-emitting control terminals. For example, in addition to transistor T07, transistors T10 and T11 can be additionally provided. Transistor T10 can be connected between transistor T07 and the privacy light-emitting device, and transistor T11 can be connected between transistor T07 and the shared light-emitting device. Transistors T10 and T11 can be connected to different light-emitting control terminals respectively. For example, the light-emitting control terminal connected to transistor T07 can be identified as EM1, the light-emitting control terminal connected to transistor T10 can be identified as EM2, and the light-emitting control terminal connected to transistor T11 can be identified as EM3. Based on this, as in Figure 7, an EM circuit can also be set up to connect to the different light-emitting control terminals EM2 and EM3 through two EN control circuits respectively, so as to independently control the light-emitting state of the privacy light-emitting device and the shared light-emitting device in a pixel.

[0109] Optionally, Figure 8 is a schematic diagram of the structure of a light-emitting control module provided in an embodiment of this application. As shown in Figure 8, the light-emitting control module 002 may include a switching part 0021 and a control part 0022.

[0110] The switch section 0021 can be connected to the enable terminal EN, the switch terminal K, and the first node N1, respectively. Furthermore, the switch section 0021 can be used to control the on / off state of the enable terminal EN and the first node N1 in response to a switch signal.

[0111] For example, the switch section 0021 can control the enable terminal EN to be connected to the first node N1 when the switch signal potential is a first potential, so that the enable signal provided by the enable terminal EN can be transmitted to the first node N1. The switch section 0021 can also control the enable terminal EN to be disconnected from the first node N1 when the switch signal potential is a second potential. That is, the potential of the first node N1 can be the potential of the enable signal.

[0112] Optionally, as mentioned above, for a P-type transistor, the first potential can be a low potential relative to the second potential; for an N-type transistor, the first potential can be a high potential relative to the second potential.

[0113] The control unit 0022 can be connected to the first power supply terminal V1, the second power supply terminal V2, the first node N1, the output terminal OUT of the light-emitting driving module 001, and the output terminal EOUT of the light-emitting control module 002, respectively. Furthermore, the control unit 0022 can, in response to the potential of the first node N1 and the light-emitting driving signal, control the switching on / off of each power supply terminal in the first power supply terminal V1 and the second power supply terminal V2 with the output terminal EOUT of the light-emitting control module 002 to output a light-emitting driving signal, and control the switching on / off of one of the power supply terminals in the first power supply terminal V1 and the second power supply terminal V2 with the output terminal EOUT of the light-emitting control module 002 to output a shutdown signal.

[0114] Optionally, the potential of the first power signal provided by the first power supply terminal V1 can be high, and the potential of the second power signal provided by the second power supply terminal V2 can be low. Here, high and low potentials can be relative. Correspondingly, the first power supply terminal V1 can also be called the pull-up power supply terminal VGH, and the second power supply terminal V2 can also be called the pull-down power supply terminal VGL.

[0115] For example, as described above, when the potential of the first node N1 (i.e., the potential of the enable signal) is at the first potential, the control unit 0022, in response to the potential of the first node N1 and the light-emitting drive signal, controls the first power supply terminal V1 and the second power supply terminal V2 to alternately conduct with the output terminal EOUT, so as to output a light-emitting drive signal including high and low potential signals to the connected pixel through the output terminal EOUT, thereby controlling the connected pixel to reliably emit light. When the potential of the first node N1 (i.e., the potential of the enable signal) is at the second potential, the control unit 0022 controls the first power supply terminal V1 or the second power supply terminal V2 to continuously conduct with the output terminal EOUT, so as to output a high or low potential off signal to the connected pixel through the output terminal EOUT, thereby controlling the connected pixel not to emit light.

[0116] It is understandable that if the transistor connected to the light-emitting control terminal EM in the pixel circuit is a P-type transistor, then the shutdown signal output through the output terminal EOUT should be a high-level signal (e.g., a high-level first power supply signal provided by the first power supply terminal V1) to reliably turn off the P-type transistor. Correspondingly, the control section 0022 can control the first power supply terminal V1 and the output terminal EOUT to remain continuously connected when the potential of the first node N1 is the second potential. If the transistor connected to the light-emitting control terminal EM in the pixel circuit is an N-type transistor, then the shutdown signal output through the output terminal EOUT should be a low-level signal (e.g., a low-level second power supply signal provided by the second power supply terminal V2) to reliably turn off the N-type transistor. Correspondingly, the control section 0022 can control the second power supply terminal V2 and the output terminal EOUT to remain continuously connected when the potential of the first node N1 is the second potential.

[0117] Optionally, based on Figure 8 and referring to Figure 9, the control section 0022 may include: a first control unit 00221, a second control unit 00222, a third control unit 00223, and a fourth control unit 00224.

[0118] The first control unit 00221 can be connected to the first node N1, the first power supply terminal V1, the second power supply terminal V2, and the second node N2, respectively. Furthermore, the first control unit 00221 can be used to control the switching between the first power supply terminal V1 and the second node N2 in response to the potential of the first node N1, and also control the switching between the second power supply terminal V2 and the second node N2.

[0119] For example, when the potential of the first node N1 is a first potential, the first control unit 00221 can control the first power supply terminal V1 to be connected to the second node N2, and control the second power supply terminal V2 to be disconnected from the second node N2, so that the high-potential first power signal provided by the first power supply terminal V1 is transmitted to the second node N2, that is, control the potential of the second node N2 to be high. The first control unit 00221 can also control the first power supply terminal V1 to be disconnected from the second node N2, and control the second power supply terminal V2 to be connected to the second node N2 when the potential of the first node N1 is a second potential, so that the low-potential second power signal provided by the second power supply terminal V2 is transmitted to the second node N2, that is, control the potential of the second node N2 to be low.

[0120] The second control unit 00222 can be connected to the second node N2, the first power supply terminal V1, the second power supply terminal V2, and the first node N1, respectively. Furthermore, the second control unit 00222 can be used to control the connection and disconnection between the first power supply terminal V1 and the first node N1 in response to the potential of the second node N2, and also control the connection and disconnection between the second power supply terminal V2 and the first node N1.

[0121] For example, when the potential of the second node N2 is a first potential (e.g., a low potential), the second control unit 00222 can control the first power supply terminal V1 to be connected to the first node N1 and control the second power supply terminal V2 to be disconnected from the first node N1, so that the high-potential first power signal provided by the first power supply terminal V1 is transmitted to the first node N1, that is, control the potential of the first node N1 to be high. The second control unit 00222 can also control the first power supply terminal V1 to be disconnected from the first node N1 and control the second power supply terminal V2 to be connected to the first node N1 when the potential of the second node N2 is a second potential (e.g., a high potential), so that the low-potential second power signal provided by the second power supply terminal V2 is transmitted to the first node N1, that is, control the potential of the first node N1 to be low.

[0122] That is, as described above, when the enable signal provided by the enable terminal EN is at a low potential, the first control unit 00221 and the second control unit 00222 can cooperate with each other to control the potential of the first node N1 to be stable at a low potential and control the potential of the second node N2 to be high potential; when the enable signal provided by the enable terminal EN is at a high potential, the first control unit 00221 and the second control unit 00222 can cooperate with each other to control the potential of the first node N1 to be stable at a high potential and control the potential of the second node N2 to be low potential.

[0123] The third control unit 00223 can be connected to the output terminal OUT of the light-emitting driving module 001, the second node N2, the other power terminal of the first power terminal V1 and the second power terminal V2, and the third node N3, respectively. Furthermore, the third control unit 00223 can be used to control the switching on and off of the second node N2 and the third node N3 in response to the light-emitting driving signal, and also control the switching on and off of the other power terminal and the third node N3.

[0124] For example, when the potential of the light-emitting driving signal is the first potential, the third control unit 00223 can control the second node N2 and the third node N3 to be turned on, and control the other power supply terminal to be turned on and off from the third node N3, so that the signal transmitted to the second node N2 is further transmitted to the third node N3, that is, control the potential of the third node N3 to be the same as the potential of the second node N2. The third control unit 00223 can also control the second node N2 and the third node N3 to be turned off when the potential of the light-emitting driving signal is the second potential, and control the other power supply terminal to be turned on and off from the third node N3, so that the power signal provided by the other power supply terminal is transmitted to the third node N3.

[0125] The fourth control unit 00224 can be connected to the third node N3, the first power supply terminal V1, the second power supply terminal V2, and the output terminal of the light-emitting control module, respectively. Furthermore, the fourth control unit 00224 can, in response to the potential of the third node N3, control the switching on / off of each of the first power supply terminals V1 and V2 with the output terminal EOUT of the light-emitting control module 002, and control the switching on / off of one of the first power supply terminals V1 and V2 with the output terminal EOUT of the light-emitting control module 002.

[0126] For example, when the potential of the third node N3 is the first potential, the fourth control unit 00224 can control the first power supply terminal V1 to be connected to the output terminal EOUT, and control the second power supply terminal V2 to be disconnected from the output terminal EOUT, so that the high-potential first power signal provided by the first power supply terminal V1 can be output through the output terminal EOUT. The fourth control unit 00224 can also control the first power supply terminal V1 to be disconnected from the output terminal EOUT, and control the second power supply terminal V2 to be connected to the output terminal EOUT when the potential of the third node N3 is the second potential, so that the low-potential second power signal provided by the second power supply terminal V2 can be output through the output terminal EOUT.

[0127] Therefore, to control the first power supply terminal V1 and the second power supply terminal V2 to alternately conduct with the output terminal EOUT, the potential of the third node N3 needs to be controlled to alternately be the first potential and the second potential. Conversely, to control the first power supply terminal V1 or the second power supply terminal V2 to continuously conduct with the output terminal EOUT, the potential of the third node N3 needs to be controlled to continuously be the first potential or the second potential. For example, to control the first power supply terminal V1 to continuously conduct with the output terminal EOUT, the potential of the third node N3 needs to be controlled to continuously be the first potential; to control the second power supply terminal V2 to continuously conduct with the output terminal EOUT, the potential of the third node N3 needs to be controlled to continuously be the second potential.

[0128] Based on this, since the potential of the second node N2 is flexible and variable, assuming that the potential of the third node N3 needs to be continuously controlled to the first potential (e.g., low potential), that is, regardless of whether the potential of the light-emitting driving signal is high or low, the potential of the third node N3 needs to be controlled to be low, as shown in Figure 9, the other power supply terminal connected to the third control unit 00223 can be the second power supply terminal V2 that can provide a low-potential power signal. Conversely, assuming that the potential of the third node N3 needs to be continuously controlled to the second potential (e.g., high potential), that is, regardless of whether the potential of the light-emitting driving signal is high or low, the potential of the third node N3 needs to be controlled to be high, as shown in Figure 10, the other power supply terminal connected to the third control unit 00223 can be the first power supply terminal V1 that can provide a high-potential power signal.

[0129] It is understandable that, since the third control unit 00223 responds to the light-emitting drive signal at the second potential and controls the other power supply terminal to conduct with the third node N3, in the scenario where the other power supply terminal connected to the third control unit 00223 is the second power supply terminal V2, and the low-potential power signal provided by the second power supply terminal V2 is transmitted to the third node N3, and then the fourth control unit 00224 controls the high-potential power signal provided by the first power supply terminal V1 to be transmitted to the output terminal EOUT, the light-emitting drive signal at the second potential should be high. Conversely, in the scenario where the other power supply terminal connected to the third control unit 00223 is the first power supply terminal V1, and the high-potential power signal provided by the first power supply terminal V1 is transmitted to the third node N3, and then the fourth control unit 00224 controls the low-potential power signal provided by the second power supply terminal V2 to be transmitted to the output terminal EOUT, the light-emitting drive signal at the second potential should be low. That is, the light-emitting drive signal should be different and inversely related depending on the other power supply terminal selected.

[0130] Accordingly, referring to the circuit structure diagram of a light-emitting driving module shown in Figure 11, the output terminal OUT of the light-emitting driving module 001 can include a first output terminal OUT1 and a second output terminal FOUT1. The first light-emitting driving signal output by the light-emitting driving module 001 through the first output terminal OUT1 and the second light-emitting driving signal output through the second output terminal FOUT1 are inverted signals. The second light-emitting driving signal can be considered as the signal obtained by inverting the first light-emitting driving signal. The control section 0022 can control the connection between the second power supply terminal V2 and the output terminal of the light-emitting control module in response to the first light-emitting driving signal, or control the connection between the first power supply terminal V1 and the output terminal of the light-emitting control module in response to the second light-emitting driving signal. That is, referring to Figure 9, when the other power supply terminal is the second power supply terminal V2, the third control unit 00223 can be connected to the first output terminal OUT1 to receive the first light-emitting driving signal; referring to Figure 10, when the other power supply terminal is the first power supply terminal V1, the third control unit 00223 can be connected to the second output terminal FOUT1 to receive the second light-emitting driving signal.

[0131] Optionally, referring to Figure 11, it can also be seen that the circuit structure of the light-emitting driving module 001 can be 18T2C (i.e., including 18 transistors T1 to T18, and 2 capacitors C1 and C2). Among them, T9 and T0 can be connected to the first output terminal OUT1, and T13 and T14 can form an inverter and be connected to the second output terminal FOUT1. The first light-emitting driving signal output from the first output terminal OUT1 is inverted and then output through the second output terminal FOUT1.

[0132] Optionally, in some embodiments, the switch terminal K may include one or more switch terminals. Accordingly, the switching portion may include one or more first transistors CT1. That is, it is not limited to the single switch terminal K shown in the figure above.

[0133] One or more first transistors CT1 can be connected in series between the enable terminal EN and the first node N1, and the gates of one or more first transistors can be connected one or more corresponding switches.

[0134] For example, the output terminal OUT of the light-emitting driver module 001 may include a first output terminal OUT1 and a second output terminal FOUT1. Based on the cascading of the light-emitting driver modules 002, as shown in Figures 12 and 13, the switch terminal K may include two sets of switch terminals K-1 and K-2. Each set of switch terminals includes two switch terminals K11 and K12. The two switch terminals K11 and K12 in one set of switch terminals K-1 can be connected to the first output terminal OUT1 and the second output terminal FOUT1 of the current stage light-emitting driver module 001, respectively. The two switch terminals K11 and K12 in the other set of switch terminals K-2 can be connected to the first output terminal OUT0 and the second output terminal FOUT0 of the cascaded previous stage light-emitting driver module, respectively.

[0135] Based on this, referring further to Figures 12 and 13, it can be seen that the switching section 0021 may include two sets of first transistors CT1-1 and CT1-2. Each set of first transistors may include two first transistors CT11 and CT12 of different types. The gates of the two first transistors CT11 and CT12 in the first set of first transistors CT1-1 are connected to the first output terminal OUT1 and the second output terminal FOUT1 of the current stage light-emitting driving module 001, respectively. The gates of the two first transistors CT11 and CT12 in the other set of first transistors CT1-2 may be connected to the first output terminal OUT0 and the second output terminal FOUT0 of the previous stage light-emitting driving module 001, respectively. The first terminals of the two first transistors CT11 and CT12 in the first set of first transistors CT1-1 may be connected to the enable terminal EN. The second terminals of the two first transistors CT11 and CT12 in the first set of first transistors CT1-1 may be connected to the first terminals of the two first transistors CT11 and CT12 in the other set of first transistors CT1-2. The second terminals of the two first transistors CT11 and CT12 in the other set of first transistors CT1-2 may be connected to the first node N1.

[0136] It is understandable that different types can refer to N-type and P-type. For example, referring to Figures 12 and 13, in a set of first transistors CT1-1, the first transistor CT11 can be a P-type transistor, and the first transistor CT12 can be an N-type transistor. The gate of the first transistor CT11 can be connected to the first output terminal OUT1, and the gate of the first transistor CT12 can be connected to the second output terminal FOUT1. In another set of first transistors CT1-2, the first transistor CT11 can be an N-type transistor, and the first transistor CT12 can be a P-type transistor. The gate of the first transistor CT11 can be connected to the first output terminal OUT0, and the gate of the first transistor CT12 can be connected to the second output terminal FOUT0.

[0137] Thus, when the potential of the first light-emitting driving signal provided by the first output terminal OUT1 and the potential of the second light-emitting driving signal provided by the second output terminal FOUT0 are both low, and the potential of the second light-emitting driving signal provided by the second output terminal FOUT1 and the potential of the first light-emitting driving signal provided by the first output terminal OUT0 are both high, all the first transistors can be turned on, making the enable terminal EN connected to the first node N1. Each group of first transistors CT1 can be regarded as a transmission gate.

[0138] Optionally, referring further to Figures 12 and 13, it can be seen that the first control unit 00221 may include: a second transistor CT2 and a third transistor CT3 of different types. For example, the second transistor CT2 may be a P-type transistor; the third transistor CT3 may be an N-type transistor.

[0139] The gates of the second transistor CT2 and the third transistor CT3 can both be connected to the first node N1. The first terminals of the second transistor CT2 and the third transistor CT3 can be connected to the first power supply terminal V1 and the second power supply terminal V2, respectively. The second terminals of the second transistor CT2 and the third transistor CT3 can both be connected to the second node N2.

[0140] The second control unit 00222 may include a fourth transistor CT4 and a fifth transistor CT5 of different types. For example, the fourth transistor CT4 may be a P-type transistor; and the fifth transistor CT5 may be an N-type transistor.

[0141] The gates of the fourth transistor CT4 and the fifth transistor CT5 can both be connected to the second node N2. The first terminal of the fourth transistor CT4 and the first terminal of the fifth transistor CT5 can be connected to the first power supply terminal V1 and the second power supply terminal V2, respectively. The second terminals of the fourth transistor CT4 and the fifth transistor CT5 can both be connected to the first node N1.

[0142] The third control unit 00223 may include a sixth transistor CT6 and a seventh transistor CT7 of different types. For example, the sixth transistor CT6 may be a P-type transistor; the seventh transistor CT7 may be an N-type transistor.

[0143] The gates of the sixth transistor CT6 and the seventh transistor CT7 can both be connected to the output terminal OUT of the light-emitting driving module 001. The first electrode of the sixth transistor CT6 and the first electrode of the seventh transistor CT7 can be connected to the second node N2 and the other power supply terminal of the first power supply terminal V1 and the second power supply terminal V2, respectively. The second electrode of the sixth transistor CT6 and the second electrode of the seventh transistor CT7 can both be connected to the third node N3.

[0144] The fourth control unit 00224 may include an eighth transistor CT8 and a ninth transistor CT9 of different types. For example, the eighth transistor CT8 may be a P-type transistor; the ninth transistor CT9 may be an N-type transistor.

[0145] The gates of the eighth transistor CT8 and the ninth transistor CT9 can both be connected to the third node N3. The first terminal of the eighth transistor CT8 and the first terminal of the ninth transistor CT9 can be connected to the first power supply terminal V1 and the second power supply terminal V2, respectively. The second terminals of the eighth transistor CT8 and the ninth transistor CT9 can both be connected to the output terminal EOUT of the light-emitting control module 002.

[0146] In other words, each control unit can actually be viewed as an inverter. The difference between Figure 12 and Figure 13 is:

[0147] In Figure 12, the sixth transistor CT6 is a P-type transistor; the seventh transistor CT7 is an N-type transistor. The first terminal of the sixth transistor CT6 is connected to the second node N2, and the first terminal of the seventh transistor CT7 is connected to the second power supply terminal V2. The gates of both the sixth transistor CT6 and the seventh transistor CT7 are connected to the first output terminal OUT1.

[0148] In Figure 13, the sixth transistor CT6 is an N-type transistor; the seventh transistor CT7 is a P-type transistor. The first terminal of the sixth transistor CT6 is connected to the second node N2, and the first terminal of the seventh transistor CT7 is connected to the first power supply terminal V1. The gates of both the sixth transistor CT6 and the seventh transistor CT7 are connected to the second output terminal FOUT1.

[0149] Optionally, referring further to Figures 12 and 13, the control section 0022 may further include: a first storage capacitor CC1 connected between the first node N1 and the second power supply terminal V2; and / or, a second storage capacitor CC2 connected between the third node N3 and the second power supply terminal V2. The first storage capacitor CC1 can be used to stabilize the potential of the first node N1; the second storage capacitor CC2 can be used to stabilize the potential of the third node N3, ensuring good potential stability of the above nodes.

[0150] Of course, the circuit structures shown in Figures 12 and 13 are schematic illustrations, and any circuit capable of achieving the above functions is applicable to this application. Optionally, taking the structure shown in Figure 12 as an example, Figure 14 schematically shows a timing diagram of one control section. Taking the structure shown in Figure 13 as an example, Figure 15 schematically shows a timing diagram of another control section.

[0151] Referring to Figures 14 and 15, it can be seen that during the same time period, the potentials of the first light-emitting driving signal output by the current stage light-emitting driving module 002 via the first output terminal OUT1 and the second light-emitting driving signal output via the second output terminal FOUT1 are exactly opposite; the potentials of the first light-emitting driving signal output by the previous stage light-emitting driving module 002 via the first output terminal OUT0 and the second light-emitting driving signal output via the second output terminal FOUT0 are also exactly opposite. Furthermore, during the same time period, the potentials of the first light-emitting driving signal output via the first output terminal OUT1 and the second light-emitting driving signal output via the second output terminal FOUT0 are both low, and simultaneously, the potentials of the second light-emitting driving signal output via the second output terminal FOUT1 and the first light-emitting driving signal output via the first output terminal OUT0 are both high. At this time, each first transistor CT1 can be turned on, making the enable terminal EN connected to the first node N1, thus enabling the enable signal provided by the enable terminal EN to be transmitted to the first node N1.

[0152] Furthermore, regarding the structure shown in Figure 12, in conjunction with Figure 14, when the enable signal provided by the enable terminal EN is at a high potential, causing the first node N1 to have a high potential, the P-type second transistor CT2 can be turned off, and the N-type third transistor CT3 can be turned on. Correspondingly, the second power supply terminal V2 (i.e., the pull-down power supply terminal VGL) can be connected to the second node N2, and the first power supply terminal V1 (i.e., the pull-up power supply terminal VGH) can be disconnected from the second node N2. Furthermore, the second power supply terminal V2 can transmit a low-potential second power signal to the second node N2, controlling the potential of the second node N2 to be low. With the potential of the second node N2 low, the P-type fourth transistor CT4 can be turned on, and the N-type fifth transistor CT5 can be turned off. Correspondingly, the first power supply terminal V1 can be connected to the first node N1, and the second power supply terminal V2 can be disconnected from the first node N1. Furthermore, the first power supply terminal V1 can transmit a high-potential first power signal to the first node N1. In other words, the potential of the first node N1 can be reliably controlled to remain high. That is, when the potential of the enable signal is high (vgh), the potential of the first node N1 can be controlled to be high, and the potential of the second node N2 can be controlled to be low.

[0153] When the enable signal provided by the enable terminal EN is at a low potential, causing the potential of the first node N1 to be low, the P-type second transistor CT2 can be turned on, and the N-type third transistor CT3 can be turned off. Correspondingly, the first power supply terminal V1 can be connected to the second node N2, and the second power supply terminal V2 can be disconnected from the second node N2. Furthermore, the first power supply terminal V1 can transmit a high-potential second power signal to the second node N2, controlling the potential of the second node N2 to be high. With the potential of the second node N2 high, the P-type fourth transistor CT4 can be turned off, and the N-type fifth transistor CT5 can be turned on. Correspondingly, the second power supply terminal V2 can be connected to the first node N1, and the first power supply terminal V1 can be disconnected from the first node N1. Furthermore, the second power supply terminal V2 can transmit a low-potential second power signal to the first node N1. That is, the potential of the first node N1 can be reliably controlled to remain low. That is, when the enable signal is at a low potential vgl, the potential of the first node N1 can be controlled to be low, and the potential of the second node N2 can be controlled to be high.

[0154] Furthermore, when the potential of the first light-emitting drive signal output through the first output terminal OUT1 is high, the P-type sixth transistor CT6 can be turned off, and the N-type seventh transistor CT7 can be turned on. Correspondingly, the second power supply terminal V2 can be connected to the third node N3, and the second node N2 can be disconnected from the third node N3. This allows the second power supply terminal V2 to transmit a low-potential second power supply signal to the third node N3. When the potential of the first light-emitting drive signal output through the first output terminal OUT1 is low, the P-type sixth transistor CT6 can be turned on, and the N-type seventh transistor CT7 can be turned off. Correspondingly, the second node N2 can be connected to the third node N3, and the second power supply terminal V2 can be disconnected from the third node N3. Since the potential of the second node N2 is low when the potential of the enable signal is high (vgh), it can be known that the potential of the third node N3 can also be controlled to be low at this time. Since the second node N2 has a high potential when the enable signal is at a low potential (vgl), it can be concluded that the third node N3 can be controlled to have a high potential at this time. That is, when the enable signal is at a high potential (vgh), the third node N3 can be controlled to remain at a low potential regardless of whether the first light-emitting drive signal is at a high or low potential; when the enable signal is at a low potential (vgl), the third node N3 can be controlled to remain at a low potential when the first light-emitting drive signal is at a high potential, and vice versa.

[0155] Finally, when the potential of the third node N3 is high, the P-type eighth transistor CT8 can be turned off, and the N-type ninth transistor CT9 can be turned on. Correspondingly, the second power supply terminal V2 can be connected to the output terminal EOUT, and the first power supply terminal V1 can be disconnected from the output terminal EOUT. Furthermore, the second power supply terminal V2 can transmit a low-potential second power supply signal to the output terminal EOUT. That is, a low-potential signal can be output through the output terminal EOUT at this time. When the potential of the third node N3 is low, the P-type eighth transistor CT8 can be turned on, and the N-type ninth transistor CT9 can be turned off. Correspondingly, the first power supply terminal V1 can be connected to the output terminal EOUT, and the second power supply terminal V2 can be disconnected from the output terminal EOUT. Furthermore, the first power supply terminal V1 can transmit a high-potential first power supply signal to the output terminal EOUT. That is, a high-potential signal can be output through the output terminal EOUT at this time.

[0156] Based on the preceding description, when the enable signal is at a high potential (vgh), regardless of whether the first light-emitting drive signal is at a high or low potential, the potential of the third node N3 can be controlled to remain at a low potential. Therefore, it can be known that a high-potential signal can be continuously output through the output terminal EOUT to control the P-type transistor connected to the light-emitting control terminal EM in the pixel circuit to remain in the off state, thereby controlling the pixel not to emit light. When the enable signal is at a low potential (vgl), when the first light-emitting drive signal is at a high potential, the potential of the third node N3 can be controlled to be at a low potential. Therefore, it can be known that a high-potential signal identical to the first light-emitting drive signal can be output through the output terminal EOUT. Conversely, when the first light-emitting drive signal is at a low potential, the potential of the third node N3 can be controlled to be at a high potential. Therefore, it can be known that a low-potential signal identical to the first light-emitting drive signal can be output through the output terminal EOUT. That is, at this time, the same signal as the first light-emitting driving signal can be output through the output terminal EOUT. This can be understood as the first light-emitting driving signal being further output to the pixel through the output terminal EOUT to control the normal switching of the P-type transistor connected to the light-emitting control terminal EM in the pixel circuit, thereby controlling the pixel to emit light.

[0157] That is, as can be seen from Figure 14, the structure shown in Figure 12 can be used to drive the P-type transistor connected to the light-emitting control terminal EM in the pixel circuit to work. When the enable signal potential is high, it can continuously output a high-potential signal to the light-emitting control terminal EM, so that the P-type transistor connected to the light-emitting control terminal EM remains off, thereby controlling the pixel not to emit light. When the enable signal potential is low, it can alternately output low-potential and high-potential signals to the light-emitting control terminal EM, so that the P-type transistor connected to the light-emitting control terminal EM switches normally, thereby controlling the pixel to emit light.

[0158] Similarly, for the structure shown in Figure 13, when the enable signal is at a high potential (vgh), the potential of the first node N1 can be controlled to be high, and the potential of the second node N2 can be controlled to be low. When the enable signal is at a low potential (vgl), the potential of the first node N1 can be controlled to be low, and the potential of the second node N2 can be controlled to be high.

[0159] The difference from Figure 12 is that when the potential of the second light-emitting drive signal output through the second output terminal FOUT1 is low, the N-type sixth transistor CT6 can be turned off, and the P-type seventh transistor CT7 can be turned on. Correspondingly, the first power supply terminal V1 can be connected to the third node N3, and the second node N2 can be disconnected from the third node N3. Furthermore, the first power supply terminal V1 can transmit a high-potential first power signal to the third node N3. When the potential of the second light-emitting drive signal output through the second output terminal FOUT1 is high, the N-type sixth transistor CT6 can be turned on, and the P-type seventh transistor CT7 can be turned off. Correspondingly, the second node N2 can be connected to the third node N3, and the second power supply terminal V2 can be disconnected from the third node N3. Since the potential of the second node N2 is high when the potential of the enable signal is low (vgl), it can be known that the potential of the third node N3 can also be controlled to be high at this time. Since the second node N2 has a low potential when the enable signal is at a high potential (vgh), it can be concluded that the third node N3 can be controlled to have a low potential at this time. That is, when the enable signal is at a low potential (vgl), the third node N3 can be controlled to remain at a high potential regardless of whether the second light-emitting drive signal is high or low; when the enable signal is at a high potential (vgh), the third node N3 can be controlled to have a high potential when the second light-emitting drive signal is low, and vice versa.

[0160] Finally, similarly, when the potential of the third node N3 is high, the P-type eighth transistor CT8 can be turned off, and the N-type ninth transistor CT9 can be turned on. Correspondingly, the second power supply terminal V2 can be connected to the output terminal EOUT, and the first power supply terminal V1 can be disconnected from the output terminal EOUT. Furthermore, the second power supply terminal V2 can transmit a low-potential second power supply signal to the output terminal EOUT. That is, a low-potential signal can be output through the output terminal EOUT at this time. When the potential of the third node N3 is low, the P-type eighth transistor CT8 can be turned on, and the N-type ninth transistor CT9 can be turned off. Correspondingly, the first power supply terminal V1 can be connected to the output terminal EOUT, and the second power supply terminal V2 can be disconnected from the output terminal EOUT. Furthermore, the first power supply terminal V1 can transmit a high-potential first power supply signal to the output terminal EOUT. That is, a high-potential signal can be output through the output terminal EOUT at this time.

[0161] Based on the preceding description, when the enable signal is at a low potential (vgl), regardless of whether the first light-emitting drive signal is at a high or low potential, the potential of the third node N3 can be controlled to remain at a high potential. Therefore, it can be known that a low-potential signal can be continuously output through the output terminal EOUT to control the N-type transistor connected to the light-emitting control terminal EM in the pixel circuit to remain in the off state, thereby controlling the pixel not to emit light. When the enable signal is at a high potential (vgh), when the second light-emitting drive signal is at a low potential, the potential of the third node N3 can be controlled to be at a high potential. Therefore, it can be known that a low-potential signal identical to the second light-emitting drive signal can be output through the output terminal EOUT. Conversely, when the second light-emitting drive signal is at a high potential, the potential of the third node N3 can be controlled to be at a low potential. Therefore, it can be known that a high-potential signal identical to the first light-emitting drive signal can be output through the output terminal EOUT. That is, at this time, the same signal as the second light-emitting driving signal can be output through the output terminal EOUT. This can be understood as the second light-emitting driving signal being further output to the pixel through the output terminal EOUT to control the normal switching of the N-type transistor connected to the light-emitting control terminal EM in the pixel circuit, thereby controlling the pixel to emit light.

[0162] That is, as can be seen from Figure 15, the structure shown in Figure 13 can be used to drive the N-type transistor connected to the light-emitting control terminal EM in the pixel circuit to work. When the enable signal potential is low, vgl, a low-potential signal can be continuously output to the light-emitting control terminal EM, so that the N-type transistor connected to the light-emitting control terminal EM remains off, thereby controlling the pixel not to emit light. When the enable signal potential is high, vgh, low-potential and high-potential signals can be alternately output to the light-emitting control terminal EM, so that the N-type transistor connected to the light-emitting control terminal EM switches normally, thereby controlling the pixel to emit light.

[0163] Optionally, as can be seen from Figures 1 to 3, in this embodiment, the privacy pixel includes a privacy pixel circuit and a privacy light-emitting element (e.g., a privacy OLED). The shared pixel includes a shared pixel circuit and a shared light-emitting element (e.g., a shared OLED). The privacy pixel circuit is connected to the privacy light-emitting element and is used to drive the privacy light-emitting element to emit light. The shared pixel circuit is connected to the privacy light-emitting element and is used to drive the shared light-emitting element to emit light. Furthermore, the privacy pixel circuit and the shared pixel circuit have the same structure. For example, both are the 9T1C structure shown in Figure 3.

[0164] Optionally, taking the structure shown in Figure 12 as an example, and the pixels shown in Figures 1 to 3, where the transistor connected to the light-emitting control terminal EM in the pixel is a P-type transistor, the different operating modes of the display panel are explained as follows:

[0165] (1) In the sharing mode, as shown in the timing diagram in Figure 16, the enable signal provided by the enable terminal EN2 of the EN2 control circuit (i.e., the light-emitting control module) that drives each row of shared pixels is at a low potential vgl. This allows the light-emitting driving signal output by the EM circuit (i.e., the light-emitting driving module) connected to the EN2 control circuit to be further transmitted to the shared pixels, thereby controlling the shared pixels to emit light. At the same time, the enable signal provided by the enable terminal EN1 of the EN1 control circuit that drives each row of privacy pixels is at a high potential vgh. This allows the EN1 control circuit to continuously output a high potential shutdown signal to the privacy pixels, thereby controlling the privacy pixels not to emit light. Thus, full-screen sharing can be achieved.

[0166] Alternatively, in conjunction with the preceding description, while controlling the shared pixel to emit light, the enable signal provided by the enable terminal EN1 of the EN1 control circuit connected to each row of privacy pixels can also be controlled to a low potential vgl. This allows the EN1 control circuit to further transmit the light-emitting drive signal output by the connected EM circuit to the privacy pixel, thereby controlling the privacy pixel to emit light. In other words, in shared mode, both the privacy pixel and the shared pixel can be controlled to emit light.

[0167] (2) In partial privacy mode, substrate 01 can be divided into a privacy region and a shared region. Based on this, and referring to the timing diagram shown in Figure 17, for the privacy region, the enable signal provided by the enable terminal EN2 of the EN2 control circuit that drives each row of shared pixels can be controlled to a high potential vgh, so that the EN2 control circuit continuously outputs a high potential shutdown signal to the shared pixels, thereby controlling the shared pixels not to emit light. At the same time, the enable signal provided by the enable terminal EN1 of the EN1 control circuit that drives each row of privacy pixels is controlled to a low potential vgl, so that the light emission driving signal output by the EM circuit connected to the EN1 control circuit is further transmitted to the privacy pixels, thereby controlling the privacy pixels to emit light.

[0168] For the shared area, the enable signal provided by the enable terminal EN2 of the EN2 control circuit driving each row of shared pixels can be controlled to a low potential (vgl). This causes the EN2 control circuit to further transmit the light-emitting drive signal output by the connected EM circuit to the shared pixels, thereby controlling the shared pixels to emit light. Simultaneously, the enable signal provided by the enable terminal EN1 of the EN1 control circuit driving each row of privacy pixels is controlled to a high potential (vgh). This causes the EN control circuit to continuously output a high potential shutdown signal to the privacy pixels, thereby controlling the privacy pixels not to emit light. In other words, privacy pixels within the privacy area emit light, while shared pixels do not; and shared pixels within the shared area emit light, while privacy pixels do not. Thus, partial privacy and partial sharing can be achieved, with the ratio of the privacy area to the shared area adjustable.

[0169] For example, in some other embodiments, as shown in FIG17, for both the shared area and the privacy area, the enable signal provided by the enable terminal EN1 connected to the EN1 control circuit driving each row of privacy pixels can be controlled to a low potential vgl, so that the light-emitting drive signal output by the EM circuit connected to the EN1 control circuit is further transmitted to the privacy pixel, thereby controlling the privacy pixel to emit light. That is, the privacy pixel is controlled to emit light in both the shared area and the privacy area.

[0170] Alternatively, the division can be based on rows, such as dividing the first n / 2 rows of pixels out of n rows into a privacy protection area, and the last n / 2 rows of pixels out of n rows into a shared area. Of course, this is just an illustrative example of the division.

[0171] It is understood that the above sharing mode and partial privacy mode are only illustrative, and other working modes (such as full privacy mode) also apply to this application.

[0172] In summary, this application provides a display panel. The display panel includes privacy pixels and shared pixels, and the light-emitting driving circuits controlling the light emission of both the privacy pixels and shared pixels include a light-emitting driving module and a light-emitting control module. Since the light-emitting control module can selectively output a light-emitting driving signal provided by the light-emitting driving module to the connected pixel to control the pixel to emit light, or output a shutdown signal to control the pixel not to emit light, the enable signal can be flexibly set to allow flexible control of the privacy pixels' light emission in privacy mode and flexible control of the shared pixels' light emission in sharing mode, thereby meeting users' needs for privacy protection and information sharing in different scenarios.

[0173] This application also provides a driving method for a display panel, which can be applied to the display panel described in the above embodiments. As shown in FIG18, the method includes:

[0174] Step 1801: In the privacy mode, the enable terminal connected to the light-emitting control module in the first light-emitting driving circuit provides an enable signal of the first potential, so that the light-emitting control module in the first light-emitting driving circuit, based on the received enable signal, the light-emitting driving signal output by the light-emitting driving module in the first light-emitting driving circuit, and the switch signal provided by the connected switch terminal, outputs a light-emitting driving signal to the connected privacy pixel to control the privacy pixel to emit light. Meanwhile, the enable terminal connected to the light-emitting control module in the second light-emitting driving circuit provides an enable signal of the second potential, so that the light-emitting control module in the second light-emitting driving circuit, based on the received enable signal, the light-emitting driving signal output by the light-emitting driving module in the second light-emitting driving circuit, and the switch signal provided by the connected switch terminal, outputs a shutdown signal to the connected shared pixel to control the shared pixel not to emit light.

[0175] Step 1802: In the sharing mode, the enable terminal connected to the light-emitting control module in the first light-emitting driving circuit provides an enable signal of the second potential. Based on the received enable signal, the light-emitting driving signal output by the light-emitting driving module in the first light-emitting driving circuit, and the switch signal provided by the connected switch terminal, the light-emitting control module in the first light-emitting driving circuit outputs a shutdown signal to the connected privacy pixel to control the privacy pixel not to emit light. Meanwhile, the enable terminal connected to the light-emitting control module in the second light-emitting driving circuit provides an enable signal of the first potential. Based on the received enable signal, the light-emitting driving signal output by the light-emitting driving module in the second light-emitting driving circuit, and the switch signal provided by the connected switch terminal, the light-emitting control module in the second light-emitting driving circuit outputs a light-emitting driving signal to the connected shared pixel to control the shared pixel to emit light.

[0176] It is understandable that Figure 18 only schematically illustrates two operating modes. As can be seen from the previous description of the display panel, the display panel can also operate in other modes, such as partial privacy protection modes, the working principle of which will not be repeated here.

[0177] It is understandable that, since the driving method of the display panel has essentially the same technical effect as the aforementioned display panel, for the sake of brevity, the technical effect of the driving method of the display panel will not be described again here.

[0178] This application also provides a display device. As shown in FIG19, the display device includes: a power supply component 10, and a display panel 00 as described in the above embodiments.

[0179] The power supply component 10 is connected to the display panel 00 and is used to supply power to the display panel 00.

[0180] Optionally, the display device described in this application embodiment can be an OLED display device. Furthermore, the display device can be any suitable display device, including but not limited to mobile phones, tablets, televisions, monitors, laptops, digital photo frames, navigators, and e-books, and any other products or components with display functions.

[0181] It is understandable that, since the display device has essentially the same technical effect as the aforementioned display panel, for the sake of brevity, the technical effect of the display device will not be described again here.

[0182] It should be noted that the terminology used in the embodiments section of this application is only for explaining the embodiments of this application and is not intended to limit this application. Unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.
