Problems solved by technology

However, as time goes by, the accumulated phase difference of each sub-screen makes the signal out of sync, so that the image data in one screen comes from two different frames, and then the picture will appear tearing, which will lead to poor user experience.
In view of this, how to reduce the probability of image display tearing on the display screen caused by signal desynchronization

Abstract

The invention discloses a signal adjustment method, electronic equipment and a computer storage medium, and the method comprises the steps of obtaining a plurality of nodes corresponding to a display screen, and synchronizing the system time of all nodes, wherein the display screen comprises a plurality of sub-screens, and each sub-screen corresponds to one node; resetting the system time for all nodes to send signals at the same time; obtaining a preset period when each node sends a signal, and obtaining theoretical system time when each node sends the signal based on the system time and the preset period; obtaining actual system time of each node for sending signals, so that a first time difference between the actual system time and the theoretical system time corresponding to each node is obtained; and in response to the fact that the first time difference corresponding to any node exceeds a preset threshold value, obtaining a time adjustment amount of the corresponding node based on the first time difference, so as to adjust the signal sending time of the corresponding node by using the time adjustment amount. According to the scheme, the probability of image display tearing on the display screen caused by signal asynchronization can be reduced.

Description

technical field [0001] The present application relates to the technical field of image display, in particular to a signal adjustment method, electronic equipment and computer storage medium. Background technique [0002] With the continuous development of smart devices, users have put forward higher requirements for the frame rate and size of the image displayed on the display screen. Therefore, a fusion screen with a high refresh rate has emerged as the times require. The entire fusion screen is composed of multiple sub-screens. A sub-screen displays part of a frame of image, and all sub-screens are combined to display a complete frame of image. However, as time goes by, the accumulated phase difference of each sub-screen makes the signal asynchronous, so that the image data in one screen comes from two different frames, and the picture will appear tearing, which will lead to poor perception for users. In view of this, how to reduce the probability of image display tearing...
