Problems solved by technology

Moreover, when the drawing speed of the AP image is slow, resulting in a delay in sending the display, the DDIC needs to perform self-refresh (repeating), that is, control the display to repeatedly refresh and display the displayed image

Abstract

The embodiment of the invention discloses an image display method, a DDIC, a display screen module and a terminal. The method is used for DDIC of a display screen, and comprises the following steps: starting frame compensation; in response to the received kth frame of image data sent by the AP, performing image scanning on the kth frame of image based on the kth frame of image data; in response to completion of image scanning, performing frame compensation on the kth frame of image based on the target compensation frequency, and outputting a TE signal in the frame compensation process; and in response to the received (k + 1) th frame of image data sent to the DDIC by the AP, completing frame compensation of the kth frame of image, and performing image scanning on the (k + 1) th frame of image based on the (k + 1) th frame of image data. In the embodiment of the invention, the DDIC continuously performs frame compensation in the image display process, so that the problem of picture flicker can be avoided, and the DDIC does not need to perform additional self-refreshing even if the AP has display delay, thereby being beneficial to reducing the display power consumption.

Description

technical field [0001] The embodiments of the present application relate to the field of display technologies, and in particular to an image display method, a display driver integrated circuit (DDIC), a display module, and a terminal. Background technique [0002] With the continuous development of display technology, high-refresh-rate displays have emerged. In order to balance display fluency and power consumption, more and more high-refresh rate displays have begun to support dynamic frequency conversion. [0003] In the process of dynamic frequency conversion, DDIC can dynamically adjust the refresh rate of the display screen according to the image drawing speed of the AP. For applications with frame rate requirements, the power consumption of the terminal can be reduced by lowering the refresh rate of the display screen. Moreover, when the drawing speed of the AP image is slow, resulting in a delay in sending the display, the DDIC needs to perform self-refresh (repeatin...
