Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a driving circuit, a driving module, a driving method, and a display device. Background Technology

[0002] 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.

[0003] 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

[0123] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0124] In all embodiments of this invention, the transistors used can be thin-film transistors, field-effect transistors, or other devices with similar characteristics. In these embodiments, to distinguish between 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.

[0125] 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.

[0126] 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.

[0127] To improve the overall battery life and user experience, we further optimized the display's operating status. We analyzed and judged 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 refreshes at a high refresh rate, while the time and status area, comment area, and operation button area refresh at a low refresh rate. This invention proposes several new drive circuit architectures through optimization of the display's drive circuitry to achieve the above-mentioned flexible display effect.

[0128] In at least one embodiment of the present invention, the display screen can achieve the following display states:

[0129] Normal display: The entire screen is scanned and refreshed line by line, with a consistent refresh rate across all positions, such as... Figure 1 As shown, in each frame of the display, each row of pixel circuits is refreshed at the same refresh rate, such as 60Hz.

[0130] Flexible display: High-frequency refresh is applied to one area, while other areas refresh at a lower frequency. The position and range of the high-frequency refresh are adjustable. Figure 2 As shown, the refresh rates of different display areas are not exactly the same in each frame; or, any area that needs to be displayed is displayed, while other areas are not displayed, such as the standby screen, where the display panel only displays the time, etc.

[0131] like Figure 1 As shown, in the effective display area A0 of the display panel, all pixel circuits have the same refresh rate.

[0132] like Figure 2As shown, 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.

Under the control of the signals provided by the at least two pull-up start control terminals, the first node control circuit controls the potential of the first node to be an effective voltage. By controlling the at least two pull-up start control terminals, the starting position of the display area can be located, and local display of any row can be realized.

[0142] In a preferred embodiment, the second control terminal may include at least two pull-down start control terminals. The first node reset circuit is used to control the potential of the first node to be an invalid voltage under the control of the signals provided by the at least two pull-down start control terminals. By controlling the at least two pull-down start control terminals, the end position of the display area can be located.

[0143] like Figure 4 As shown, the driving circuit described in at least one embodiment of the present invention further includes a cascaded control circuit 40;
