Title:
VIDEO SIGNAL TRANSMISSION METHOD AND APPARATUS, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/143612
Kind Code:
A1
Abstract:
Provided are a video signal transmission method and apparatus, and a display device, wherein same relate to the technical field of displays. In the solution provided in the present disclosure, a pulse synchronization signal can be generated on the basis of a source end timing signal and an output frame rate, and an output end timing signal is generated on the basis of the pulse synchronization signal. Therefore, the periodic synchronization of the source end timing signal and the output end timing signal can be realized, and the influence of continuous accumulation of clock errors on the image display effect of a display module can thus be prevented. Moreover, since a synchronization cycle is an integer multiple of a cycle of the source end timing signal and is an integer multiple of a cycle corresponding to the output frame rate, it can be ensured that timing synchronization is completed in a blanking interval, so as to prevent the influence of timing synchronization on the normal display of an image.
