IMAGE DISPLAY SYSTEM AND IMAGE PROCESSING METHOD CAPABLE OF SUPPORTING UHD VIDEO/IMAGE DATA DISPLAY

摘要

Disclosed are an image display system and an image processing method in which an image processing device conducts division of one frame data of an external digital image signal to obtain a plurality of sub-frame data, then converts the plurality of sub-frame data respectively into a plurality of LVDS video signals, and successively transmits the LVDS video signals to a display device in accordance with a switching signal and a synchronization signal. Upon receipt of the LVDS video signal, the display device processes the LVDS video signals so as to generate a display image signal, which corresponds to the frame data and is displayed thereon.

主权项

1. An image display system comprising:
a display device; and an image processing device including
a video processing unit configured to receive an external digital image signal, which includes at least one image frame, said video processing unit including
a video decoding module for decoding the digital image signal to obtain one frame data of the digital image signal that corresponds to the image frame,a video adjusting module for conducting division of the frame data to obtain a plurality of sub-frame data, each of which corresponds to a respective portion of the image frame, anda video encoding module for encoding the plurality of sub-frame data respectively into a plurality of low-voltage differential signaling (LVDS) video signals, andan output module coupled to said video processing unit and said display device, and successively transmitting the LVDS video signals from said video processing unit to said display device in accordance with a switching signal and a synchronization signal, so that each of the LVDS video signals is transmitted within a cycle period of the synchronization signal and so that all the LVDS video signals are transmitted within a cycle period of the switching signal; wherein said display device receives the LVDS video signals from said output module of said image processing device in accordance with the switching signal and the synchronization signal, and processes the LVDS video signals so as to generate a display image signal, which corresponds to the frame data and is displayed thereon.
