Description
Technical Field
[0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background Art
[0002] Organic Light Emitting Display (OLED) and flat display devices based on technologies such as Light Emitting Diode (LED) have been widely used in various consumer electronic products such as mobile phones, televisions, laptops, desktop computers, etc. due to their advantages of high image quality, power saving, thin body and wide application range, becoming the mainstream of display devices. However, current display panels cannot achieve multi-frequency display in horizontal areas. Summary of the invention
[0003] The present invention provides a display panel and a display device, which can realize partitioned multi-frequency display in a horizontal area.
[0004] In a first aspect, an embodiment of the present invention provides a display panel, comprising at least two display partitions, wherein the at least two display partitions include a first display partition and a second display partition, and the first display partition and the second display partition are adjacent to each other in a direction perpendicular to a data line; the at least two display partitions respectively include a plurality of pixel circuit groups; the display panel also includes a first scanning circuit, a plurality of first scanning lines and a plurality of first gating circuits; the first scanning circuit is electrically connected to the first scanning line through the first gating circuit, and the first scanning line is connected to the corresponding pixel circuit group; the first gating circuit is used to turn on or off the first scanning line and the first scanning circuit, and is also used to transmit an off-level signal to the first scanning line.
[0005] In a second aspect, an embodiment of the present invention provides a display device, including the display panel provided by any embodiment of the present invention.
[0006] The display panel provided by the embodiment of the present invention includes a plurality of first gating circuits, which are respectively connected to the first scanning circuit and the first scanning line. The first input end of the first gating circuit receives the scanning signal output by the first scanning circuit, and the second input end is connected to the off-level signal. By responding to the signal on the gating signal line, the first gating circuit can determine the connection state between the first scanning circuit and the first scanning line. When the first gating circuit is turned on, the scanning signal is transmitted to the pixel circuit, prompting the pixel switch state to change; when the first gating circuit is turned off, the scanning signal is blocked, or the shift register cannot generate the scanning signal, and the pixel circuit cannot receive the scanning signal. In different display partitions, the gating signals received by the first gating circuit are different, thereby realizing differentiated control of the transmission of scanning signals in different partitions. For example, at certain moments, the first gating circuit of the first display partition is turned off, and the pixel circuit of the partition does not receive the scanning signal, while the first gating circuit of the second display partition is turned on, and its pixel circuit normally receives the scanning signal, so that the refresh frequency of the two partitions is different. Each display partition includes a plurality of pixel circuit groups, and the pixel circuits in the pixel circuit group control the display state of the pixel according to the scanning signal transmitted by the first scanning line. Due to the control of the first gating circuit on the transmission of the scanning signal, the pixel circuits of different partitions receive the scanning signal at different frequencies. When the first gating circuit of the first display partition is turned off during a specific period of time, the pixel circuit of the partition cannot receive the scanning signal and does not perform data writing operations; while the first gating circuit of the second display partition is in the on state, its pixel circuit can normally receive the scanning signal and write data, ultimately making different display partitions present different refresh frequencies, realizing partition multi-frequency display in the horizontal area.

[0019] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.
[0021] As described in the background technology, the existing display panel cannot realize the partitioned multi-frequency display in the horizontal area. The inventors have found that the reason for the above problem is that the display panel often adopts the method of longitudinal partitioned multi-frequency to reduce the power consumption of the screen body, usually by controlling the output of the gate drive (GIP) circuit integrated in the control panel, so that the frequency output of the GIP circuit in different areas is inconsistent, so as to achieve inconsistent refresh rates at different positions of the screen body, but according to this principle, it is impossible to effectively realize the partitioned multi-frequency of the horizontal area.
[0022] In order to solve the above technical problem, an embodiment of the present invention provides a display panel. Figure 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present invention. Figure 1 As shown, the display panel includes at least two display partitions, the at least two display partitions include a first display partition AA1 and a second display partition AA2, and the first display partition AA1 and the second display partition AA2 are adjacent to each other along a direction X perpendicular to the data line. The at least two display partitions respectively include a plurality of pixel circuit groups 10; the display panel also includes a first scanning circuit 11, a plurality of first scanning lines GL1, and a plurality of first gating circuits 12.
[0023] The first scanning circuit 11 is electrically connected to the first scanning line GL1 through the first gating circuit 12, and the first scanning line GL1 is connected to the corresponding pixel circuit group 10; the first gating circuit 12 is used to turn on or off the first scanning line GL1 and the first scanning circuit 11, and is also used to transmit the shutdown level signal VGH to the first scanning line GL1.
[0024] Specifically, the pixel circuit group 10 includes a plurality of columns of pixel circuits PX, and the pixel circuits PX may have the structure of any existing pixel driving circuit. The first scanning circuit 11 may include a plurality of cascaded shift registers 111, and each stage of the shift register 111 may be connected to a first scanning line GL1 through a corresponding first gating circuit 12, and the first scanning line GL is connected to a functional module in one or more columns of the pixel circuits PX, for example, a functional module in the pixel circuit PX for controlling the gate of the driving transistor for initialization.
[0025] The first scanning circuit 11 is used to output a first scanning signal according to at least an input signal and a clock signal, and the first scanning signal is transmitted to the first scanning line GL1 through the first gating circuit 12. The first scanning line GL1 is used to transmit the first scanning signal generated by the first scanning circuit 11 to the pixel circuit group 10, so as to control the switching state of the pixel and realize the row-by-row display of the image. Exemplarily, when the display panel includes multiple rows of pixel circuits PX, multiple shift registers in each first scanning circuit 11 are cascaded. Multiple cascaded shift registers 111 respectively provide the first scanning signal to at least one column of pixel circuits PX through the corresponding first gating circuit 12. Among them, the input signal of the first-stage shift register 111 may include the input signal provided by the driving chip to the start signal line STV, and the input signal of the other-stage shift registers 111 may be the scanning signal output by the previous-stage shift register 111.
[0026] The first scanning signal output by the first scanning circuit 11 may include an effective level and an ineffective level, wherein the effective level is a level for controlling the conduction of a functional module in the pixel circuit, and the ineffective level is a level for controlling the shutoff of a functional module in the pixel circuit. The effective level may be a high level, and the ineffective level may be a low level; or, the effective level may be a low level, and the ineffective level may be a high level. The embodiments of the present invention are all described by taking the ineffective level as a high level and the effective level as a low level as an example. Optionally, the ineffective level is the same as the shutoff level signal VGH.
[0027] The first gating circuit 12 includes a first input terminal, a second input terminal and an output terminal. The first input terminal of the first gating circuit 12 is connected to the output terminal of the first scanning circuit 11 to receive the first scanning signal output by the first scanning circuit 11. The second input terminal of the first gating circuit 12 is connected to the off-level signal VGH. When the first input terminal of the first gating circuit 12 is connected to the output terminal, the first scanning signal is transmitted to the corresponding first scanning line GL1 through the output terminal of the first gating circuit 12. When the second input terminal of the first gating circuit 12 is connected to the output terminal, the off-level signal VGH is transmitted to the corresponding first scanning line GL1 through the output terminal of the first gating circuit 12. The off-level signal VGH is the cut-off potential of the functional module connected to the first scanning signal in the pixel circuit. The functional module is, for example, a functional module that controls the data voltage writing process of the gate of the driving transistor in the pixel circuit. When realizing the multi-frequency display of the horizontal area partition, the first gating circuits 12 of different display partitions work according to the signal on the gating signal line. When it is necessary to stop the pixel writing data voltage of a certain partition to achieve different refresh frequencies, the first selection circuit 12 transmits the off-level signal VGH to the first scan line GL1. This operation cuts off the transmission of the first scan signal, so that the pixel circuit of the corresponding partition cannot receive the first scan signal and does not write data, thereby generating a difference in refresh frequency with other partitions, and realizing partition multi-frequency display. In addition, during the switching process of the connection state between the first scan circuit 11 and the first scan line GL1, there may be residual first scan signals. If these residual signals are not processed, they may interfere with the normal operation of the pixel circuit, resulting in noise, ghosting and other problems in the display. Transmitting the off-level signal VGH to the first scan line GL1 can effectively cover the possible residual first scan signal, so that the level on the first scan line GL1 is in a certain off state. In this way, the residual scan signal can be avoided from false triggering of the pixel circuit, the clarity and stability of the displayed picture can be ensured, and the overall performance of the display panel can be improved.
[0028] The first scanning circuit 11 is electrically connected to the first scanning line GL1 through the first gating circuit 12. The first gating circuit 12 is responsible for gating or shutting off the first scanning line GL1 and the first scanning circuit 11, and transmitting the shutoff level signal VGH. When the first input end of the first gating circuit 12 is connected to its output end, the first scanning signal can be transmitted to the pixel circuit PX to control the switching state of the pixel; when the first input end of the first gating circuit 12 is disconnected from its output end, the first scanning signal is blocked or the pixel circuit PX cannot receive the first scanning signal. In this way, the first gating circuits 12 of different display partitions can realize differentiated control of the transmission of the first scanning signal according to the different gating signals, thereby making the refresh frequencies of different display partitions different.
[0029] Each display partition includes a plurality of pixel circuit groups 10, and the pixel circuits PX in the pixel circuit groups control the display state of the pixels according to the first scan signal transmitted by the first scan line GL1. Due to the control of the first scan signal by the first gating circuit 12, the pixel circuits PX in different partitions receive the first scan signal at different frequencies, thereby achieving different refresh frequencies. For example, when the first gating circuit 12 of the first display partition AA1 is turned off at certain moments, the pixel circuit PX of the first display partition AA1 cannot receive the first scan signal and does not write data, while the first gating circuit 12 of the second display partition AA2 is turned on, and its pixel circuit PX normally receives the first scan signal and writes data, so that the refresh frequencies of the first display partition AA1 and the second display partition differ.
[0030] The display panel provided by the embodiment of the present invention includes a plurality of first gating circuits, which are respectively connected to the first scanning circuit and the first scanning line. The first input end of the first gating circuit receives the first scanning signal output by the first scanning circuit, and the second input end is connected to the off-level signal. The first gating circuit is responsible for gating or shutting off the first scanning line and the first scanning circuit, and transmitting the off-level signal. When the first input end of the first gating circuit is connected to its output end, the first scanning signal is transmitted to the pixel circuit, causing the pixel switch state to change; when the first input end of the first gating circuit is disconnected from its output end, the first scanning signal is blocked, and the pixel circuit cannot receive the first scanning signal. In different display partitions, the gating signals received by the first gating circuit are different, thereby realizing differentiated control of the transmission of scanning signals in different partitions. For example, at certain moments, the first gating circuit of the first display partition is turned off, and the pixel circuit of the partition does not receive the first scanning signal, while the first gating circuit of the second display partition is turned on, and its pixel circuit normally receives the first scanning signal, so that the refresh frequencies of the two partitions are different. Each display partition includes multiple pixel circuit groups, and the pixel circuits in the pixel circuit group control the display state of the pixel according to the first scanning signal transmitted by the first scanning line. Due to the control of the first selection circuit on the transmission of the first scanning signal, the pixel circuits in different partitions receive the first scanning signal at different frequencies. When the first input end and the output end of the first selection circuit of the first display partition are turned off during a specific period of time, the pixel circuit of the partition cannot receive the first scanning signal and does not perform data writing operations; while the first input end and the output end of the first selection circuit of the second display partition are in a conducting state, and its pixel circuit can normally receive the scanning signal and write data, which ultimately makes different display partitions present different refresh frequencies, realizing partition multi-frequency display in the horizontal area.
[0031] Optionally, continue to refer to Figure 1The display panel further includes a plurality of clock signal lines and a driving chip, wherein the driving chip is connected to the first scanning circuit 11 through the clock signal lines to output a clock signal to the first scanning circuit. The driving chip can input clock signals to at least two clock signal lines, and the clock signal lines can transmit the clock signals to the first scanning circuit 11. Figure 1 The example shows that the multiple clock signal lines may include a first clock signal line CK1 and a second clock signal line CK2, which is not limited in any way. The first clock signal line CK1 may be set to provide a first clock signal to an odd-numbered shift register, and a second clock signal to an even-numbered shift register. The second clock signal line CK2 may be set to provide a second clock signal to an odd-numbered shift register, and a first clock signal to an even-numbered shift register.
[0032] Optionally, continue to refer to Figure 1 The display panel also includes a plurality of selection signal lines SE1, the selection signal lines SE1 are correspondingly connected to the first selection circuit 12, the first selection circuit 12 is used to switch on or off the first scanning line 12 and the first scanning circuit 11 according to the signal on the selection signal line SE1, and is also used to transmit the shutdown level signal VGH to the first scanning line GL1 according to the signal on the selection signal line SE1.
[0033] Specifically, the first selection circuit 12 can determine the connection state between the first scanning line GL1 and the first scanning circuit 11 according to the signal state on the selection signal line SE1. When the signal on the selection signal line SE1 controls the first input end of the first selection circuit 12 to be turned on with its output end, and controls the second input end of the first selection circuit 12 to be turned off with its output end, the first selection circuit 12 selects the first scanning line GL1 and the first scanning circuit 11. At this time, the first scanning signal output by the first scanning circuit 11 is transmitted to the first scanning line GL1 through the first selection circuit 12, and then transmitted to the corresponding pixel circuit group 10, to control the switching state of the pixel, and realize the line-by-line display of the image. Conversely, when the signal on the selection signal line SE1 controls the first input end of the first selection circuit 12 to be turned off with its output end, and controls the second input end of the first selection circuit 12 to be turned on with its output end, the first selection circuit 12 will transmit the connected off-level signal VGH to the first scanning line GL1. The shutdown level signal VGH is the cutoff potential of the relevant functional modules in the pixel circuit. Transmitting it to the first scanning line GL1 can cut off the corresponding functional modules in the pixel circuit, ensure that the pixel circuit is in a stable non-working state, avoid false triggering due to factors such as residual signals, and ensure the accuracy and stability of the display state of the display panel.
[0034] Figure 2 FIG. 1 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention. Figure 2As shown, optionally, the gate signal line SE1 includes a first gate signal line SE11 and a second gate signal line SE12.
[0035] The first gating circuit 12 includes a first gating unit 121 and a second gating unit 122, wherein the control end of the first gating unit 121 is connected to the first gating signal line SE11, the first end of the first gating unit 121 is connected to the first scanning circuit 11, and the second end of the first gating unit 121 is connected to the first scanning line GL1, and is used to switch the first scanning line GL1 and the first scanning circuit 11 on or off according to the signal on the first gating signal line SE11.
[0036] The control end of the second selection unit 122 is connected to the second selection signal line SE12, the first end of the second selection unit 122 is connected to the first scanning line GL1, and the second end of the second selection unit 122 is connected to the shutdown level signal VGH, which is used to transmit the shutdown level signal VGH to the first scanning signal line GL1 according to the signal on the second selection signal line SE12.
[0037] In at least one frame of the display period of the display panel, the signals transmitted on the first selection signal line SE11 and the second selection signal line SE12 in the first display partition AA1 are different from the signals transmitted on the first selection signal line SE11 and the second selection signal line SE12 in the second display partition AA2.
[0038] Specifically, the signal on the first selection signal line SE11 determines the on or off state of the first selection unit 121. When the signal on the first selection signal line SE11 is at an effective level, the first selection unit 121 connects the first scanning circuit 11 and the first scanning line GL1, so that the first scanning signal generated by the first scanning circuit 11 can be transmitted to the first scanning line GL1, providing a control signal for the pixel circuit group to realize the row-by-row display of the image.
[0039] The signal on the second selection signal line SE12 controls the working state of the second selection unit 122. When the signal on the first selection signal line SE11 is at an invalid level, the second selection unit 122 is turned on, and the off-level signal VGH is transmitted to the first scanning line GL1, so that the relevant functional modules in the pixel circuit are turned off, ensuring that the pixel circuit is in a stable non-working state, and avoiding false triggering caused by residual signals.
[0040] In a display period of a display panel, the signals transmitted on the first selection signal line SE11 and the second selection signal line SE12 of the first display partition AA1 and the second display partition AA2 are different. This signal difference makes the working state of the first selection circuit 12 of the two partitions different. At a certain moment, the first selection unit 121 of the first display partition AA1 may be turned off due to the signal of the first selection signal line SE11, and the pixel of the partition is stopped from writing the data voltage; while the first selection unit 121 of the second display partition AA2 remains turned on due to the different signals and continues to write data, thereby achieving different refresh frequencies of the two partitions to meet the display requirements of different scenes. In this implementation, the selection signal line and the selection unit are subdivided, and the first selection unit 121 and the second selection unit 122 are controlled respectively by different selection signal lines, thereby improving the control accuracy of the connection between the first scanning circuit 11 and the first scanning line GL1 and the turn-off level signal VGH. Differentiated signal control of different partitions can more accurately control the working state of each partition, reduce signal interference, enhance the stability of the display panel, improve display quality, and reduce the occurrence of display problems such as noise and ghosting.
[0041] Optionally, the first selection signal line SE11 in each display partition is connected to the first selection units 121 of all rows. This means that the signal transmitted by the first selection signal line SE11 can simultaneously control the working state of the first selection units 121 of all rows. When the signal on the first selection signal line SE11 changes, the first selection units 121 of all rows will synchronously turn on or off the first scanning circuit 11 and the first scanning line GL1 according to the signal, thereby determining whether the first scanning signal can be transmitted to each pixel circuit group.
[0042] Optionally, the second selection signal line SE12 in each display partition is connected to the second selection unit 122 of all rows. The signal transmitted by the second selection signal line SE12 can simultaneously control the second selection units 122 of all rows, determine whether to transmit the shutdown level signal VGH to the first scan line GL1, and then control the cut-off state of the relevant functional modules in the pixel circuit. By connecting the first selection signal line SE11 to the first selection unit 121 of all rows, it can be ensured that the pixel circuits of all rows in the same display partition remain synchronized when receiving the first scan signal. When displaying an image, there will be no problems such as asynchronous display and misalignment of different rows in the same partition, ensuring the consistency and stability of the display of the entire partition. The connection between the second selection signal line SE12 and the second selection unit 122 of all rows also makes the pixel circuits of all rows consistent in the control of the shutdown state, avoiding display defects caused by untimely or abnormal shutdown of some rows.
[0043] As a preferred embodiment provided by the embodiment of the present invention, Figure 3FIG. 1 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention. Figure 3 As shown, optionally, the first selection unit 121 includes a first transistor T1, the gate of the first transistor T1 serves as the gate of the first selection unit 121, the first electrode of the first transistor T1 serves as the first end of the first selection unit 121, and the second electrode of the first transistor T1 serves as the second end of the first selection unit 121.
[0044] Specifically, when the signal transmitted by the first selection signal line SE11 causes the gate voltage of the first transistor T1 to reach the conduction threshold, the first transistor T1 is turned on. At this time, a conductive path is formed between the first electrode (connected to the first scanning circuit 11) and the second electrode (connected to the first scanning line GL1) of the first transistor T1, and the first scanning signal generated by the first scanning circuit 11 can be transmitted to the first scanning line GL1 through the first transistor T1, providing a control signal for the pixel circuit group 10 to realize the line-by-line display of the image. When the gate voltage is lower than the conduction threshold, the first transistor T1 is turned off, cutting off the connection between the first scanning circuit 11 and the first scanning line GL1, and preventing the transmission of the scanning signal.
[0045] Optionally, the second selection unit 122 includes a second transistor T2, the gate of the second transistor T2 serves as the control end of the second selection unit 122, the first electrode of the second transistor T2 serves as the first end of the second selection unit 122, and the second electrode of the second transistor T2 serves as the second end of the second selection unit 122.
[0046] Specifically, when the signal transmitted by the second selection signal line SE12 makes the gate voltage of the second transistor T2 meet the conduction condition, the second transistor T2 is turned on. The first electrode of the second transistor T2 is connected to the first scanning line GL1, and the second electrode is connected to the off-level signal VGH. When turned on, the off-level signal VGH is transmitted to the first scanning line GL1 through the second transistor T2, so that the relevant functional modules in the pixel circuit are turned off, avoiding false triggering caused by residual signals, and ensuring that the pixel circuit is in a stable non-working state. When the gate voltage does not meet the conduction condition, the second transistor T2 is turned off, and the transmission of the off-level signal VGH is stopped.
[0047] Figure 4 is a waveform diagram of a signal transmitted on a first selection signal line and a second selection signal line provided by an embodiment of the present invention. Figure 4 Exemplarily, the signal on the first selection signal line SE11 is the first selection signal E1, and the signal on the second selection signal line SE12 is the second selection signal E2. In the same phase, the first selection signal E1 and the second selection signal E2 have opposite levels.
[0048] refer to Figure 3 and Figure 4In the first stage P1, that is, when the first selection signal E1 is at an invalid level (such as a high level) and the second selection signal E2 is at an effective level (such as a low level), the first transistor T1 is turned off, the second transistor T2 is turned on, and the off-level signal VGH is transmitted to the first scan line GL1; in the second stage P2, that is, when the first selection signal E1 is at a low level and the second selection signal E2 is at a high level, the first transistor T1 is turned on, the first scanning circuit 11 is connected to the first scanning line GL1, and the scanning signal is transmitted. At this time, the second transistor T2 is turned off, preventing the off-level signal VGH from being transmitted to the first scanning line GL1. This setting of opposite levels ensures that at any time, the first scanning line GL1 either transmits the scanning signal or is in a stable state under the control of the off-level signal VGH, avoiding confusion caused by the simultaneous appearance of the two signals. If the levels of the two are not opposite, the first transistor T1 and the second transistor T2 may be turned on or turned off at the same time, causing a conflict between the scanning signal and the off-level signal VGH, or the first scanning line GL1 cannot obtain the required signal in time, affecting the normal operation of the pixel circuit, resulting in abnormal display.
[0049] Optionally, continue to refer to Figure 2 and Figure 3 , the refresh frequency of the first display partition AA1 is a first refresh frequency, the refresh frequency of the second display partition AA2 is a second refresh frequency, and the first refresh frequency is less than the second refresh frequency.
[0050] In the first frame, the signal on the first selection signal line SE11 in the first display partition AA1 and the second display partition AA2 is at a valid level, and the signal on the second selection signal line SE12 in the first display partition AA1 and the second display partition AA2 is at an invalid level, so that the sub-pixels in the first display partition AA1 and the second display partition AA2 are both written with data voltages.
[0051] In the second frame, the signal on the first selection signal line SE11 in the first display partition AA1 is at an invalid level, and the signal on the second selection signal line SE12 is at a valid level; the signal on the first selection signal line SE11 in the second display partition AA2 is at a valid level, and the signal on the second selection signal line SE12 is at an invalid level, so that the data voltage is not written to the sub-pixels in the first display partition AA1, and the data voltage is written to the sub-pixels in the second display partition AA2.
[0052] Specifically, the display cycle of the display panel includes a plurality of display frames, and the first frame and the second frame are any two frames. In the first frame, the signal on the first selection signal line SE11 of the two partitions is at a valid level, and the signal on the second selection signal line SE12 is at an invalid level. At this time, the first transistor T1 in the first selection unit 121 is turned on, the first scanning circuit 11 is connected to the first scanning line GL1, and the first scanning signal is transmitted to the pixel circuit group. At the same time, the second transistor T2 in the second selection unit 122 is turned off, and the off-level signal VGH cannot be transmitted to the first scanning line GL1. This enables the sub-pixels in the first display partition AA1 and the second display partition AA2 to write data voltages, preparing for subsequent display.
[0053] In the second frame, the first selection signal line SE11 of the first display partition AA1 becomes an invalid level, and the second selection signal line SE12 becomes an effective level, causing the first transistor T1 to be turned off, the second transistor T2 to be turned on, the scanning signal to be cut off, the shutdown level signal VGH transmission, and the sub-pixel in the partition does not write the data voltage; while the second display partition AA2 maintains the first selection signal line SE11 valid and the second selection signal line SE12 invalid, and the sub-pixel continues to write the data voltage. In this way, by setting the selection signals of the two frames, the sub-pixels in different partitions are controlled to write data at different times. Since the first display partition AA1 does not write the data voltage in the second frame, the second display partition AA2 writes normally. In one display cycle, the number of times the second display partition AA2 writes the data voltage is relatively more. The refresh frequency is related to the number of data writes per unit time. The more the number of writes, the higher the refresh frequency. Therefore, by using the differentiated setting of the two partition selection signals in the first frame and the second frame, the refresh frequency of the second display partition AA2 is higher than that of the first display partition AA1, and the partition multi-frequency display of the horizontal area of the display panel is achieved to meet the display refresh rate requirements of different scenes.
[0054] Figure 5 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention. Figure 5 The display panel also includes a second scanning circuit 13, a plurality of second scanning lines GL2 and a plurality of second gating circuits 14; the second scanning circuit 13 is electrically connected to the second scanning line GL2 via the second gating circuit 14, and the second scanning line GL2 is connected to the corresponding pixel circuit group 10; the second gating circuit 14 is used to switch on or off the second scanning line GL2 and the second scanning circuit 13, and is also used to transmit the shutdown level signal VGH to the second scanning line GL2.
[0055] Specifically, the second scanning circuit 13 is used to output a second scanning signal at least according to the input signal and the clock signal, and the second scanning signal is transmitted to the second scanning line GL2 through the second gating circuit 14. The second scanning line GL2 is used to transmit the second scanning signal generated by the second scanning circuit 13 to the pixel circuit group 10, so as to control the switching state of the pixel and realize the row-by-row display of the image. Exemplarily, when the display panel includes multiple rows of pixel circuits PX, multiple first shift registers 131 in each second scanning circuit 13 are cascaded. Multiple cascaded first shift registers 131 respectively provide a second scanning signal to at least one column of pixel circuits PX through the corresponding second gating circuit 14. Among them, the input signal of the first shift register 131 of the first stage may include the input signal provided by the driving chip to the first start signal line STV1, and the input signal of the first shift register 131 of other stages may be the second scanning signal output by the first shift register 131 of the previous stage. Among them, the structures of the shift register 111 and the first shift register 131 may be the same or different, and the embodiment of the present invention is not limited to this.
[0056] The first scanning signal output by the second scanning circuit 13 may include an effective level and an ineffective level, wherein the effective level is a level for controlling the conduction of a functional module in the pixel circuit, and the ineffective level is a level for controlling the shutoff of a functional module in the pixel circuit. For example, the level for controlling the shutoff of the initialization module in the pixel circuit PX. The effective level may be a high level, and the ineffective level may be a low level; or, the effective level may be a low level, and the ineffective level may be a high level. The embodiments of the present invention are all described by taking the ineffective level as a high level and the effective level as a low level as an example. Optionally, the ineffective level is the same as the shutoff level signal VGH.
[0057] The second gating circuit 14 includes a first input terminal, a second input terminal and an output terminal. The first input terminal of the second gating circuit 14 is connected to the output terminal of the second scanning circuit 13 to receive the second scanning signal output by the second scanning circuit 13. The second input terminal of the second gating circuit 14 is connected to the shutdown level signal VGH. When the first input terminal of the second gating circuit 14 is connected to the output terminal and the second input terminal of the second gating circuit 14 is disconnected from the output terminal, the second scanning signal is transmitted to the corresponding second scanning line GL2 through the output terminal of the second gating circuit 12. The second scanning signal generated by the second scanning circuit 13 can reach the pixel circuit group 10 through the second scanning line GL2, thereby participating in the control of the pixel, for example, playing a role in the initialization operation of the pixel circuit.
[0058] When the second input terminal and the output terminal of the first gating circuit 12 are connected, and the first input terminal and the output terminal of the second gating circuit 14 are disconnected, the shutdown level signal VGH is transmitted to the corresponding second scanning line GL2 through the output terminal of the second gating circuit 14. The shutdown level signal VGH can turn off the functional modules in the pixel circuit (such as the initialization module), ensure that the pixel circuit is in a stable state, avoid pixel mis-triggering due to abnormal signals, and ensure the stability and accuracy of the displayed image.
[0059] Optionally, continue to refer to Figure 5 The display panel also includes a plurality of selection signal lines SE1, which are connected to the second selection circuit 14 accordingly. The second selection circuit 14 is used to switch on or off the second scanning line GL2 and the second scanning circuit 14 according to the signal on the selection signal line SE1, and is also used to transmit the off-level signal to the second scanning line GL2 according to the signal on the selection signal line SE1.
[0060] Figure 6 is a schematic diagram of the structure of a second gating circuit provided by an embodiment of the present invention. Figure 6 Optionally, the gate signal line SE1 includes a first gate signal line SE11 and a second gate signal line SE12.
[0061] The second gating circuit 14 includes a third gating unit 141 and a fourth gating unit 142, the control end of the third gating unit 141 is connected to the first gating signal line SE11, the first end of the third gating unit 141 is connected to the second scanning circuit 13, and the second end of the third gating unit 142 is connected to the second scanning line GL2, and is used to turn on or off the second scanning line GL2 and the second scanning circuit 13 according to the signal on the first gating signal line SE1.
[0062] The control end of the fourth selection unit 142 is connected to the second selection signal line SE12, the first end of the fourth selection unit 142 is connected to the second scan line GL2, and the second end of the fourth selection unit 142 is connected to the shutdown level signal VGH, which is used to transmit the shutdown level signal to the second scan line GL2 according to the signal on the second selection signal line SE12.
[0063] Specifically, the signal on the first selection signal line SE11 determines the on or off state of the third selection unit 141. When the signal on the first selection signal line SE11 is at an effective level, the third selection unit 141 connects the first scanning circuit 11 and the second scanning line GL2, so that the first scanning signal generated by the first scanning circuit 11 can be transmitted to the second scanning line GL2, providing a control signal for the pixel circuit group 10 to realize the row-by-row display of the image.
[0064] The signal on the second selection signal line SE12 controls the working state of the fourth selection unit 142. When the signal on the first selection signal line SE11 is at an invalid level, the fourth selection unit 142 is turned on, and the off-level signal VGH is transmitted to the second scanning line GL2, so that the relevant functional modules in the pixel circuit are turned off, ensuring that the pixel circuit is in a stable non-working state, and avoiding false triggering caused by residual signals.
[0065] Optionally, the first selection signal line SE11 in each display partition is connected to the third selection units 141 of all rows. This means that the signal transmitted by the first selection signal line SE11 can simultaneously control the working state of the third selection units 141 of all rows. When the signal on the first selection signal line SE11 changes, the third selection units 141 of all rows will synchronously turn on or off the second scanning circuit 13 and the second scanning line GL2 according to the signal, thereby determining whether the second scanning signal can be transmitted to each pixel circuit group.
[0066] Optionally, the second selection signal line SE12 in each display partition is connected to the fourth selection unit 142 of all rows. The second selection signal line SE12 is connected to the fourth selection unit 142 of all rows, which means that in the same display partition, the pixel circuits of all rows can maintain synchronization when receiving the shutdown level signal VGH. When the second selection signal line SE12 transmits a signal to turn on the fourth selection unit 142, the second scan lines GL2 of all rows will simultaneously access the shutdown level signal VGH, so that the relevant functional modules in each pixel circuit are synchronously cut off. In this way, the display inconsistency problem caused by the untimely or abnormal shutdown of some rows can be avoided, and the picture of the entire display partition is guaranteed to be stable and flicker-free, thereby improving the display quality. When displaying a static picture, the unified shutdown control can ensure that all pixels are in a stable state to prevent noise or other display defects.

[0068] Specifically, when the signal transmitted by the first selection signal line SE11 causes the gate voltage of the third transistor T3 to reach the conduction threshold, the third transistor T3 is turned on. At this time, a conductive path is formed between the first electrode (connected to the second scanning circuit 13) and the second electrode (connected to the second scanning line GL2) of the third transistor T3, and the second scanning signal generated by the second scanning circuit 13 can be transmitted to the second scanning line GL2 through the third transistor T3, providing a control signal for the pixel circuit group 10 to realize the line-by-line display of the image. When the gate voltage is lower than the conduction threshold, the third transistor T3 is turned off, cutting off the connection between the second scanning circuit 13 and the second scanning line GL2, and preventing the transmission of the scanning signal.
[0069] Optionally, the fourth selection unit 142 includes a fourth transistor T4, the gate of the fourth transistor T4 serves as the control end of the fourth selection unit 142, the first electrode of the fourth transistor T4 serves as the first end of the fourth selection unit 142, and the second electrode of the fourth transistor T4 serves as the second end of the fourth selection unit 142.
[0070] Specifically, when the signal transmitted by the second selection signal line SE12 makes the gate voltage of the fourth transistor T4 meet the conduction condition, the fourth transistor T4 is turned on. The first electrode of the fourth transistor T4 is connected to the second scan line GL2, and the second electrode is connected to the off-level signal VGH. When turned on, the off-level signal VGH is transmitted to the second scan line GL2 through the fourth transistor T4, so that the relevant functional modules in the pixel circuit are turned off, avoiding false triggering caused by residual signals, and ensuring that the pixel circuit is in a stable non-working state. When the gate voltage does not meet the conduction condition, the fourth transistor T4 is turned off, and the transmission of the off-level signal VGH is stopped.

Exemplarily, the working process of the pixel circuit in a display frame at least includes a first initialization stage P1, a data writing and threshold compensation stage P2, a second initialization stage P3 and a light emitting stage P4. After the end of the i-1th display frame, the i-th display frame is entered. i is an integer greater than or equal to 2.
[0090] In the first initialization phase P1 of the i-th display frame, the first initialization module 140 is turned on, the threshold compensation module 130, the data writing module 120, the second initialization module 170, the first light emission control module 161 and the second light emission control module 162 are turned off. That is, the first initialization transistor M3 is turned on, and the data writing transistor M1, the threshold compensation transistor M2, the second initialization transistor M6, the first light emission control transistor M4 and the second light emission control transistor M5 are turned off. The first initialization voltage transmitted by the first initialization voltage line Vref1 is written into the gate of the driving transistor DTFT through the first initialization transistor M3, the gate voltage of the driving transistor DTFT is reset to the first initialization voltage, and the driving transistor DTFT is controlled to be turned on.

The data voltage transmitted by the data line Data is sequentially written into the gate of the driving transistor DTFT through the data writing transistor M1, the driving transistor DTFT and the threshold compensation transistor M2, so that the gate voltage of the driving transistor DTFT is related to both the data voltage and the threshold voltage of the driving transistor DTFT, and the gate voltage of the driving transistor DTFT is stored through the storage capacitor Cst.
[0092] In the light-emitting phase P3 of the i-th display frame, the second initialization module 170 is turned on, and the threshold compensation module 130, the data writing module 120, the first initialization module 140, the first light-emitting control module 161 and the second light-emitting control module 162 are turned off.
