[0001] Cross-references to related applications
[0002] This application claims priority to Chinese Patent Application No. 202411535758.5, filed in China on October 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to the field of display technology, and in particular to a driving circuit, driving module, driving method and display device. Background Technology
[0004] Currently, all areas of the displays on the market have a single refresh rate, such as the common 30Hz, 60Hz, 90Hz, 120Hz, and 144Hz. To comprehensively consider the battery life and user experience, current system integrators typically use a low refresh rate (e.g., 60Hz) for static display scenarios like reading ebooks, and switch to a high refresh rate (e.g., 120Hz) for watching videos or playing games.
[0005] To further improve overall battery life and user experience, the optimal solution is for the display to support flexible display, with different areas of the screen corresponding to different refresh rates. That is, areas requiring a high refresh rate should be refreshed at a high refresh rate, and areas requiring a low refresh rate should be refreshed at a low refresh rate, adjusting the refresh rate according to the current displayed image. However, current products are limited by the GOA (Gate Driver On Array) model and cannot achieve this effect. Summary of the Invention

[0125] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0126] In all embodiments of this disclosure, the transistors used can be thin-film transistors, field-effect transistors, or other devices with similar characteristics. In the embodiments of this disclosure, to distinguish the two terminals of the transistor other than the gate, one terminal is referred to as the first terminal and the other as the second terminal.
[0127] In actual operation, when the transistor is a thin-film transistor or a field-effect transistor, the first electrode can be the drain and the second electrode can be the source; or, the first electrode can be the source and the second electrode can be the drain.
[0128] Currently, various mobile video apps are popular among users. To enhance the video viewing experience and interactivity, users often watch videos in a small window mode (video playback occurs only in a small area of the screen), while simultaneously viewing comments below. The entire display screen can be divided into four areas from top to bottom: time and status area, video playback area, comment area, and operation button area. Currently, the screen refresh rate is the same in all four areas. To increase the refresh rate of the video playback area, the refresh rate of all areas would be increased simultaneously, leading to increased screen power consumption and significantly shortening the overall battery life.
[0129] To improve the overall battery life and user experience, we have further optimized the display's operating status. We analyze and judge the displayed image, using a high refresh rate for areas requiring a high refresh rate and a low refresh rate for areas where a low refresh rate is possible. For example, the video playback area is refreshed at a high refresh rate, while the time and status area, comment area, and operation button area are refreshed at a low refresh rate. This disclosure proposes several new drive circuit architectures through optimization of the display's drive circuitry to achieve the above-mentioned flexible display effect.
[0130] In at least one embodiment of this disclosure, the display screen can achieve the following display states:
[0131] Normal display: The entire screen is scanned and refreshed line by line, and the refresh rate is consistent in all positions, as shown in Figure 1. In each frame of the display, each row of pixel circuits is refreshed at the same refresh rate, such as 60Hz.
[0132] Flexible display: Any area can be refreshed at a high frequency, while other areas can be refreshed at a low frequency. The position and range of the high-frequency refresh are adjustable, as shown in Figure 2. In each frame, the refresh rates of different display areas are not exactly the same; or, any area that needs to be displayed can be displayed, while other areas are not displayed, such as the standby screen, where the display panel only displays the time, etc.
[0133] As shown in Figure 1, in the effective display area A0 of the display panel, all pixel circuits have the same refresh rate.
[0134] As shown in Figure 2, the effective display area of the display panel may include at least two areas with different refresh rates, such as three areas, for example, a first display area A1, a second display area A2 and a third display area A3. The refresh rate corresponding to the first display area A1 may be, for example, 40Hz, the refresh rate corresponding to the second display area A2 may be, for example, 80Hz, and the refresh rate corresponding to the third display area A3 may be, for example, 40Hz.

[0385] When at least one embodiment shown in Figure 13 is in operation, and flexible or local display is performed as shown in Figure 18, and the refreshed area is repeatedly displayed within the second display area A2, the working timing diagram is shown in Figure 19.
[0386] In Figure 18, the effective display area includes a first display area A1, a second display area A2, a third display area A3, a fourth display area A4, and a fifth display area A5 arranged from top to bottom.
[0387] In Figure 19, the time of frame a is labeled Fa, the time of frame a+1 is labeled Fa+1, the time of frame a+2 is labeled Fa+2, and the time of frame a+3 is labeled Fa+3, where a is a positive integer.

[0437] When a high-frequency refresh rate is required across two or more display areas (taking the second and fourth display areas as an example), multiple refreshes can be performed only on the drive circuits corresponding to the second and fourth display areas. Since the drive circuits for other display areas have no high-level input, their drive signal outputs remain consistently low. Because only two display areas are refreshed, the refresh time is shortened, allowing for an increase in the frequency of partial refreshes.
