Abstract
The invention discloses a spliced display screen with built-in image processors. The spliced display screen comprises at least two display units with built-in image processors. The built-in image processors contain output signal processing modules and high-speed serial processing modules; the display unit built-in image processor connected with an original input signal source also includes an input signal processing module. All display units are mutually connected by the high-speed serial processing modules. According to the spliced display screen, because a multi-path independent serial connecting mechanism is employed, when a fault occurs at any processing module, a phenomenon that the large screen is in a black state and thus displaying can not be carried out can be prevented, so that the large screen can work safety for long time. Moreover, because of direct access of the video signal, multi-times conversion and processing of access signals can be reduced; and the image displaying effect with best quality can be guaranteed.
