[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0045] It should be noted that the terms "first," "second," etc., used in this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0046] As people's living standards improve, they are constantly exposed to electronic products, leading to a surge in demand for display panels and rapid development in display technology. Ordinary display effects are no longer sufficient to meet people's quality of life. Another highlight is the use of zone refresh technology, where different areas of the display panel refresh at different frequencies. This results in better power efficiency and extends the lifespan of electronic products. However, when zone refresh is enabled, inconsistent frequencies in different areas can cause uneven display, such as dark or bright bands in certain sub-areas. Figure 1 This is a schematic diagram of a display panel displaying the same grayscale image. (See reference) Figure 1 When entering the partition refresh mode, the refresh rates of the first display sub-area 11, the second display sub-area 12, and the third display sub-area 13 of the display panel are different. When moving from a low refresh rate to a high refresh rate display sub-area, the first part of the pixel row of the high refresh rate display sub-area appears darker, causing uneven display brightness of the display panel. Figure 2 This is a schematic diagram of a pixel circuit provided in an embodiment of the present invention, for reference. Figure 2 Under partitioned refresh, due to capacitor leakage in the low refresh rate display sub-area or the unstable voltage (stable voltage is) in the high refresh rate display sub-area... Figure 3 Factors such as a drop in voltage (corresponding to a straight line) can cause display sub-areas with low refresh rates to appear too bright or those with high refresh rates to appear too dark. Specifically, pixel circuit 22 includes compensation module 120. The control terminal of compensation module 120 receives the output signal of the second scanning circuit. The pulse frequency of the output signal of the second scanning circuit can be controlled by a partition enable signal. For example, Figure 3 This is a schematic diagram showing the level changes of different partition enable signals when moving from a low refresh rate display sub-region to a high refresh rate display sub-region. (Refer to...) Figure 3 , Figure 3The system includes four partition enable signal lines, VFE1, VFE2, VFE3, and VFE4, transmitting partition enable signals. The stable voltage of the partition enable signal VFE transmitted by VFE1, VFE2, VFE3, and VFE4 decreases sequentially. According to the inventor's research and analysis, the reason why the display sub-area at high refresh rates appears darker is that during the scanning process of a local refresh frame, when moving from a display sub-area at a low refresh rate (e.g., 1Hz) to a display sub-area at a high refresh rate (120Hz), the partition enable signal VFE needs to change from a low level to a high level. This is equivalent to a change in voltage between the low refresh rate (e.g., 1Hz) and the high refresh rate (e.g., 1Hz) display sub-area within a local refresh frame. During the time period corresponding to the display sub-area, the partition enable signal is at a disabled level, such as a low level, so that the second scanning circuit does not output a conduction pulse to the display sub-area with a low refresh rate, and continuously outputs the off level of the compensation module 120. During the scanning time period corresponding to the display sub-area with a high refresh rate (120Hz), the partition enable signal VFE is at an enabled level, such as a high level, so that the second scanning circuit outputs a conduction pulse to the display sub-area with a high refresh rate, so that the compensation module 120 is turned on. However, due to load changes, the partition enable signal VFE cannot switch directly from a low level to a high level, and there is a certain delay. Figure 3 The rise of the middle partition enable signal VFE is a delayed process, i.e., the area circled in red. This causes the high voltage at the control terminal of the transistor in the compensation module 120 of the first partition 121 to be lower than the subsequent stable state. The pull-down coupling of the transistor in the compensation module 120 is relatively weak, resulting in a deviation in the control terminal voltage of the transistor in the drive module 110. For example, the control terminal voltage is too high, causing the first part of the sub-pixel row of the high refresh rate display sub-region (i.e., the first partition 121) to appear darker and abnormal.
[0047] To address the aforementioned technical problems, embodiments of the present invention provide a display panel, see reference. Figure 1 and Figure 2The display panel includes a first display sub-area 11 and a second display sub-area 12, arranged sequentially along a first direction X. The refresh rate of the first display sub-area 11 is different from that of the second display sub-area 12. The second display sub-area 12 includes a first area 121 and a second area 122, with the second area 122 located on the side of the first area 121 away from the first display sub-area 11. The first display sub-area 11, the first area 121, and the second area 122 each include multiple pixel rows 20, and each pixel row 20 includes multiple sub-pixels arranged sequentially along a second direction Y. 21; wherein, the first direction X and the second direction Y intersect each other; each sub-pixel 21 includes a pixel circuit 22, and each pixel circuit 22 includes an initialization voltage terminal, which is used to provide an initialization voltage Vrefn1 to the pixel circuit 22; the initialization voltage Vrefn1 of the pixel circuit 22 of the first display sub-region 11 is different from the initialization voltage Vrefn1 of the pixel circuit 22 of the first region 121, and the initialization voltage Vrefn1 of the pixel circuit 22 of the first region 121 is different from the initialization voltage Vrefn1 of the pixel circuit 22 of the second region 122.
[0048] The refresh rate of the first display sub-area 11 is different from that of the second display sub-area 12. For example, the refresh rate of the first display sub-area 11 can be lower than that of the second display sub-area 12. For instance, the refresh rate of the first display sub-area 11Hz can be 10Hz, 30Hz, 60Hz, or 120Hz. This embodiment of the invention addresses the problem of uneven brightness in the display panel by differentiating the initialization voltage in the main control unit (MCU) module of the display driver chip (DDIC). The main control unit can identify and bind the initialization voltage of the corresponding area based on the partition refresh coordinates, i.e., the number of pixels at the beginning and end of the high refresh rate area, or the information of the display position. The flexible variation of the initialization voltage in different areas can improve the brightness of the first area 121 and avoid the problem of poor display effect in the dark areas of the first area 121.
[0049] The first display sub-region 11, the first region 121, and the second region 122 each include multiple pixel rows 20, which are spaced apart. Each pixel row 20 includes multiple sub-pixels 21 arranged sequentially along the second direction Y. Each sub-pixel 21 includes a pixel circuit 22 and a light-emitting device 200. The pixel circuit 22 can be used to drive the light-emitting device 200 to emit light. The light-emitting device 200 may include an OLED. In one image frame, the initialization voltage terminal provides an initialization voltage Vrefn1 to the first display sub-region 11 during a first time period. The pixel circuit 22 corresponding to the sub-pixels 21 of the multiple pixel rows 20 in the first display sub-region 11 receives the initialization voltage Vrefn1 of the first display sub-region 11. The initialization voltage terminal provides an initialization voltage Vrefn1 to the first region 121 during a second time period. The pixel circuit 22 corresponding to the sub-pixels 21 of the multiple pixel rows 20 in the first region 121 receives the initialization voltage Vrefn1 of the first region 121. The initialization voltage terminal provides an initialization voltage Vrefn1 to the second region 122 during a third time period. The pixel circuit 22 corresponding to the sub-pixels 21 of the multiple pixel rows 20 in the second region 122 receives the initialization voltage Vrefn1 of the second region 122.
[0050] For example, the initialization voltage Vrefn1 can be the voltage used to initialize the control terminal of the driving module 110 of the pixel circuit. By providing different initialization voltages Vrefn1 to different areas, the excessively large voltage of the control terminal of the driving module 110 can be offset, changing the driving current of the sub-pixels in the first area 121, thereby adjusting the light emission brightness of the sub-pixels in the first area 121 and avoiding the appearance of dark bands in the first area 121 that cause uneven display brightness of the display panel. Alternatively, the initialization voltage can be the voltage used to initialize the anode of the light-emitting device 200. By providing different initialization voltages Vrefn1 to different areas, the driving current corresponding to the light-emitting element 20 can be changed, thereby adjusting the brightness of each sub-pixel and improving the problem of uneven display brightness of the display panel.
[0051] In this embodiment of the invention, the initialization voltage Vrefn1 of the pixel circuit 22 of the first display sub-region 11 is different from that of the pixel circuit 22 of the first region 121, and the initialization voltage Vrefn1 of the pixel circuit 22 of the first region 121 is different from that of the pixel circuit 22 of the second region 122. That is, the first display sub-region 11, the first region 121 and the second region 122 have different initialization voltages Vrefn1, thereby adjusting the driving current output by the pixel circuits of the first display sub-region 11, the first region 121 and the second region 122, so that the light emission brightness of the first display sub-region 11, the first region 121 and the second region 122 is similar or the same, thereby improving the problem of uneven display brightness of the display panel.
[0052] The technical solution of this embodiment of the invention sets up a first display sub-region 11 and a second display sub-region 12, with the refresh frequency of the first display sub-region 11 being different from that of the second display sub-region 12; the second display sub-region 12 includes a first region 121 and a second region 122, and both the first display sub-region 11, the first region 121 and the second region 122 include multiple pixel rows 20, each pixel row 20 including multiple sub-pixels 21 arranged sequentially along the second direction Y, each sub-pixel 21 including a pixel circuit 22, and each pixel circuit 22 including an initialization voltage terminal, which is used to provide an initialization voltage Vre to the pixel circuit 22. fn1; The initialization voltage Vrefn1 of the pixel circuit 22 of the first display sub-region 11 is different from the initialization voltage Vrefn1 of the pixel circuit 22 of the first region 121. The initialization voltage Vrefn1 of the pixel circuit 22 of the first region 121 is different from the initialization voltage Vrefn1 of the pixel circuit 22 of the second region 122. This adjusts the driving current output by the pixel circuits of the first display sub-region 11, the first region 121 and the second region 122, so that the light emission brightness of the first display sub-region 11, the first region 121 and the second region 122 is similar or the same, thus improving the problem of uneven display brightness of the display panel.
[0053] Optional, see reference Figure 1 and Figure 2 The pixel circuit 22 includes a driving module 110, and an initialization voltage Vrefn1 is used to initialize the control terminal G of the driving module 110. The refresh frequency of the first display sub-area 11 is less than the refresh frequency of the second display sub-area 12. The absolute value of the initialization voltage Vrefn1 of the first display sub-area 11 is less than the absolute value of the initialization voltage Vrefn1 of the first area 121, the absolute value of the initialization voltage Vrefn1 of the first area 121 is greater than the absolute value of the initialization voltage Vrefn1 of the second area 122, and the absolute value of the initialization voltage Vrefn1 of the first display sub-area 121 is less than the absolute value of the initialization voltage Vrefn1 of the second area 122.
[0054] In this system, the refresh rate of the first display sub-area 11 is lower than that of the second display sub-area 12. In the partitioned refresh mode, the first area 121 will produce a dark band, and the brightness of the first display sub-area 11, the first area 121, and the second area 122 will exhibit a bright-dark-bright phenomenon. The luminous brightness of the sub-pixel 21 is related to the magnitude of the driving current. The initial voltage of the control terminal G of the driving module 110 can be adjusted by the initialization voltage Vrefn1. The larger the absolute value of the initialization voltage Vrefn1, the more fully the capacitor Cst in the storage module 190 in the pixel circuit 22 is reset. The larger the absolute value of the initialization voltage of the control terminal G of the driving module 110, the larger the driving current output by the driving module 110 under the same data voltage, and the higher the luminous brightness of the sub-pixel 21. Therefore, the absolute value of the initialization voltage Vrefn1 of the first display sub-area 11 is set to be less than the absolute value of the initialization voltage Vrefn1 of the first area 121, and the absolute value of the initialization voltage Vrefn1 of the first area 121 is greater than the absolute value of the initialization voltage Vrefn1 of the second area 122. The absolute value of the initialization voltage Vrefn1 of the first display sub-area 121 is less than the absolute value of the initialization voltage Vrefn1 of the second area 122. That is, the absolute value of the initialization voltage Vrefn1 of the first area 121 > the absolute value of the initialization voltage Vrefn1 of the second area 122 > the absolute value of the initialization voltage Vrefn1 of the first display sub-area 11. The first area 121 has a large absolute value of initialization voltage Vrefn1, which can offset the voltage deviation of the control terminal of the drive module 110, thereby reducing the brightness difference between the first display sub-area 11, the first area 121 and the second area 122, and achieving overall brightness balance of the display panel. This avoids the problem of uneven display brightness of the display panel and improves the display brightness of the display panel.
[0055] Optional, see reference Figure 2 The driving module 110 includes a driving transistor T1, which is a P-type transistor with a negative initial voltage.
[0056] The driving module 110 includes a driving transistor T1, which is a P-type transistor. An initialization voltage Vrefn1 provides a negative voltage value to the driving transistor T1. For example, the initialization voltage Vrefn1 of the first display sub-area 11 can be -4V, the initialization voltage Vrefn1 of the first area 121 can be -4.5V, and the initialization voltage Vrefn1 of the second area 122 can be -4.2V. Since a lower initialization voltage leads to a more sufficient reset of the storage capacitor Cst in the storage module 190, the voltage at the control terminal of the driving module 110 will be lower. This increases the driving current output by the driving module 110, improves the brightness of the sub-pixels, and raises the overall brightness of the first area 121 to match that of the first display sub-area 11. This reduces the brightness difference between the first area 121 and the first display sub-area, preventing dark bands from appearing in the high refresh rate area of the first area 121, thereby improving the display effect of the display panel.
[0057] Optional, Figures 4-7 This is a schematic diagram of a display panel and its corresponding initialization voltage provided in an embodiment of the present invention. (Refer to...) Figure 2 , Figures 4-7 Along the first direction X, the initial voltage Vrefn1 of the multiple pixel rows 20 of the first region 121 gradually increases, and the initial voltage Vrefn1 of each pixel row 20 is the same; or, the initial voltage Vrefn1 of the multiple pixel rows 20 of the first region 121 is the same fixed value.
[0058] in, Figure 4 The left side shows a schematic diagram of the display panel. Figure 4 The right side includes initialization voltages Vrefn1 corresponding to different display sub-regions. The first region 121 includes multiple pixel rows 20, each pixel row 20 includes multiple sub-pixels 21 arranged along the second direction Y, and each sub-pixel 21 includes a pixel circuit 22. The initialization voltages Vrefn1 of the pixel circuits 22 of the multiple sub-pixels 21 in each pixel row 20 are the same. Along the first direction X, the initialization voltages Vrefn1 of the multiple pixel rows 20 in the first region 121 are gradually increased. Figures 4-7The initial voltage Vrefn1 of the first zone 121 is gradually increased. The smaller the initial voltage Vrefn1, the larger the absolute value of the initial voltage Vrefn1. Since the pixel row of the first display sub-zone 11 adjacent to the first zone 121 is darker than the pixel row 20 of the second zone 122 adjacent to the first zone 121, the initial voltage Vrefn1 of the first zone 121 is gradually increased. The brightness of the pixel row that is closer to the first zone 121 increases, so that the brightness of each pixel row of the first zone 121 is close to that of the first display sub-zone 11. This further reduces the difference in display brightness of the sub-pixels 21 of adjacent pixel rows 20 and improves the display effect of the display panel.
[0059] Along the first direction X, setting the initial voltage Vrefn1 of multiple pixel rows 20 in the first area 121 to the same fixed value can make the initial voltage Vrefn1 of the pixel circuit 22 of each sub-pixel 21 in the first area 121 the same, making the driving method simpler, and can reduce the difference in luminous brightness between the sub-pixel 21 in the first area 121 and the sub-pixel in the first display sub-area 11, reduce the difference in display brightness of the display panel, and improve the display effect of the display panel.
[0060] Optional, see reference Figure 2 , Figures 4-7 The initial voltage Vrefn1 of multiple pixel rows 20 in the first region 121 increases in a step-like manner, a curved manner, or a straight manner.
[0061] in, Figure 4 and Figure 5 The initial voltage Vrefn1 in the first region 121 increases linearly. Figure 6 and Figure 7 The initial voltage Vrefn1 of the first zone 121 increases in a step-like manner; the initial voltage Vrefn1 of the first zone 121 can increase in a step-like manner, a curve, or a straight line, and the driving method is simple. Specifically, the growth mode of the initial voltage Vrefn1 can be selected according to the brightness distribution of each pixel row in the first zone 121, so as to achieve precise control of the brightness of each pixel row in the first zone 121, reduce the display brightness difference of the display panel, and improve the display effect of the display panel.
[0062] Optional, see reference Figure 2 , Figures 4-7 The initial voltage Vrefn1 of multiple pixel rows 20 in the second region 122 gradually increases, and the initial voltage Vrefn1 of each pixel row 20 is the same; or the initial voltage Vrefn1 of multiple pixel rows 20 in the second region 122 is a fixed value.
[0063] in, Figure 4 and Figure 6The initial voltage Vrefn1 of multiple pixel rows 20 in the second region 121 is the same fixed value. Figure 5 and Figure 7 The initialization voltage Vrefn1 of multiple pixel rows 20 in the second region 121 gradually increases. Since the enable signal voltage in the second region 122 tends to be stable, the brightness of the second region 122 is close to that in the first display sub-region 11. Therefore, it is necessary to set the initialization voltage Vrefn1 in the second region 122 to be close to the initialization voltage Vrefn1 in the first display sub-region 11. By setting the initialization voltage Vrefn1 of multiple pixel rows 20 in the second region 122 to gradually increase along the first direction X, that is, the absolute value of the initialization voltage Vrefn1 in the second region 122 gradually decreases, so that the initialization voltage Vrefn1 of the second region 122 gradually transitions to be close to the initialization voltage Vrefn1 of the first display sub-region 11, avoiding a sudden change in the initialization voltage of the second region 122, which would cause a sudden change in brightness at the junction of the second region 122 and the first region 121. Furthermore, when there is a third display sub-area 13 with a low refresh rate in the display panel, the initialization voltage of the sub-pixels of the second area 122 can smoothly transition to the same initialization voltage as the third display sub-area 13, avoiding brightness changes at the junction of the second area 122 and the third display sub-area 13 due to changes in the initialization voltage Vrefn1, thereby reducing the difference in display brightness of the display panel and improving the display effect of the display panel.
[0064] Along the first direction X, setting the initial voltage Vrefn1 of multiple pixel rows 20 in the second region 122 to the same fixed value ensures that the initial voltage Vrefn1 of the pixel circuit 22 of each sub-pixel 21 in the second region 122 is the same, simplifying the driving method and improving the display effect of the display panel. Optionally, the initial voltage Vrefn1 of multiple pixel rows 20 in the second region 122 increases in a step-like manner, a curved manner, or a linear manner.
[0065] The initial voltage Vrefn1 of the second zone 122 increases in a step-like, curved, or linear manner. The driving method is simple. Specifically, the growth mode of the initial voltage Vrefn1 can be selected according to the brightness distribution of each pixel row in the second zone 122, so as to achieve precise control of the brightness of each pixel row in the second zone 122, reduce the brightness difference of the display panel, and improve the display effect of the display panel.
[0066] Optional, see reference Figure 2 and Figure 5 Along the first direction X, the initial voltage Vrefn1 of multiple pixel rows 20 of the second display sub-region 12 gradually increases.
[0067] In this process, the initial voltage Vrefn1 of the multi-row pixel circuit 22 in the second display sub-area 12 gradually increases. The initial voltage Vrefn1 of the second area 122 is greater than the initial voltage Vrefn1 of the first area 121. While reducing the difference in luminous brightness between the first area 121 and the first display sub-area 11 and the second area 122, the luminous brightness of the second display sub-area 12 can be smoothly transitioned, making the display brightness of the second display sub-area 12 more uniform and the overall display effect of the display panel better.
[0068] Optionally, the initial voltage Vrefn1 of the multiple pixel rows 20 of the second display sub-region 12 increases in a step-like manner, a curved manner, or a linear manner.
[0069] Among them, the initial voltage Vrefn1 of the second display sub-region 12 increases in a step-like manner, a curved manner, or a linear manner, which makes the driving method simpler.
[0070] Optional, see reference Figure 4 The display panel also includes: a third display sub-area 13, the refresh rate of the third display sub-area 13 being the same as the refresh rate of the first display sub-area 11; the third display sub-area 13 including a plurality of pixel rows 20, each pixel row 20 including a plurality of sub-pixels 21 arranged sequentially along the second direction Y; the first display sub-area 11, the second display sub-area 12 and the third display sub-area 13 are arranged sequentially along the first direction X; the initialization voltage Vrefn1 of the pixel circuit 22 of the third display sub-area 13 is the same as the initialization voltage Vrefn1 of the pixel circuit 22 of the first display sub-area 11.
[0071] The refresh rate of the third display sub-area 13 is lower than that of the second display sub-area 12, but equal to that of the first display sub-area 11. By setting the first display sub-area 11, second display sub-area 12, and third display sub-area 13 along the first direction X of the display panel, it can be adapted to the display requirements of different areas of the display panel. The initialization voltage Vrefn1 of the pixel circuit of the third display sub-area 13 is the same as that of the pixel circuit of the first display sub-area 11. This simplifies the driving algorithm, facilitates control, and ensures that the display brightness of the first display sub-area 11 is the same as that of the third display sub-area 13, thereby reducing the difference in display brightness across the display panel and improving its overall brightness.
[0072] Optional, Figure 8 This is a schematic diagram of another pixel circuit provided in an embodiment of the present invention, for reference. Figure 2 , Figures 4-7 and Figure 8The pixel circuit 22 includes a driving module 110 and a first initialization module 130. The first terminal of the first initialization module 130 is connected to the control terminal G or the second terminal D of the driving module 110, and the second terminal of the first initialization module 130 is the initialization voltage terminal. The first initialization module 130 is used to initialize the control terminal G of the driving module 110.
[0073] The display panel further includes: a first scanning circuit, which is connected to the control terminal of the first initialization module 130 via a first scanning line; the first scanning circuit is used to transmit a first scanning signal SN1 sequentially to the control terminal of the first initialization module 130 of each pixel circuit 22 of the first display sub-area 11, the control terminal of the first initialization module 130 of each pixel circuit 22 of the first area 121, and the control terminal of the first initialization module 130 of each pixel circuit 22 of the second area 122.
[0074] The driving module 110 and the first initialization module 130 each include transistors. For example, the driving module 110 includes a P-type driving transistor T1, and the first initialization module includes an N-type fourth transistor T4. (Reference) Figure 2 , Figure 2 The first terminal of the first initialization module 130 is connected to the second terminal D of the drive module 110. Under the control of the first scan signal SN1, the initialization voltage Vrefn1 in the first initialization module 130 is transmitted to the control terminal G of the drive transistor through the first initialization module 130 and the compensation module 120 to initialize the control terminal G of the drive module 110; Reference Figure 8 , Figure 8 The first terminal of the first initialization module 130 is connected to the control terminal G of the driving module 110. Under the control of the first scan signal SN1, the initialization voltage Vrefn1 in the first initialization module 130 is transmitted to the control terminal G of the driving transistor through the first initialization module 130 to initialize the control terminal G of the driving module 110. By adjusting the initialization voltage Vrefn1 of different display sub-areas, the driving current of the pixel circuit 22 can be adjusted, thereby adjusting the light emission brightness of the sub-pixels in the pixel circuit 22, so that the brightness of different display sub-areas is balanced, and the display effect of the display panel is improved.
[0075] Specifically, the first scanning circuit is used to sequentially transmit the first scanning signal SN1 to the control terminal of the first initialization module 130 of each pixel circuit 22 of the first display sub-area 11, the control terminal of the first initialization module 130 of each pixel circuit 22 of the first area 121, and the control terminal of the first initialization module 130 of each pixel circuit 22 of the second area 122. The first display sub-area 11 with a low refresh rate usually corresponds to a large area of background in the image. These parts have relatively small changes, and a low refresh rate can meet the visual requirements. Scanning the first display sub-area 11 with a low refresh rate first can reduce the refresh power consumption of this area while ensuring the visual effect. The first area 121 and the second area 122 with a high refresh rate contain information such as image details and require a higher refresh rate to present a clear effect. However, since their area is relatively small, scanning the low-frequency area first and then performing high-frequency scanning can avoid unnecessary power waste and achieve optimized power management.
[0076] Optional, see reference Figures 4-7 and Figure 8 The display panel also includes a third display sub-area 13, with the first display sub-area 11, the second display sub-area 12 and the third display sub-area 13 arranged sequentially along the first direction X; the first scanning circuit is used to sequentially transmit the first scanning signal SN1 to the control terminal of the first initialization module 130 of each pixel circuit 22 of the first display sub-area 11, the control terminal of the first initialization module 130 of each pixel circuit 22 of the second display sub-area 12 and the control terminal of the first initialization module 130 of each pixel circuit 22 of the third display sub-area 13.
[0077] In this process, the first scanning circuit sequentially transmits the first scanning signal SN1 to the control terminals of the first initialization module 130 of each pixel circuit 22 in the first display sub-area 11, the second display sub-area 12, and the third display sub-area 13. The first and third display sub-areas 11 and 13, which have low refresh rates, typically correspond to large areas of background in the image. These areas have relatively small variations, and a lower refresh rate is sufficient to meet visual requirements. Scanning the first display sub-area 11, which has a low refresh rate, firstly reduces the refresh power consumption of this area while ensuring visual quality. The first and second areas 121 and 122, which have high refresh rates, contain details and other information in the image and require higher refresh rates to present a clear effect. However, since their areas are relatively small, scanning the low-frequency areas first and then performing high-frequency scanning avoids unnecessary power consumption waste and optimizes power consumption management. Finally, scanning the third display sub-area 13, which has a low refresh rate, further optimizes the overall power consumption without affecting the visual quality, achieving refined power consumption management.
