Abstract

The invention provides display processing equipment and a multi-screen display system applying the same. The display processing equipment comprises a plurality of processing modules, a clock module and a plurality of frequency multiplication modules, wherein the clock module is connected with frequency multiplication modules respectively; each frequency multiplication module is in one-to-one connection with each processing module; the clock module is used for acquiring a synchronous clock and outputting the synchronous clock to each frequency multiplication module; the frequency multiplication modules are used for performing frequency multiplication on the synchronous clock respectively and transmitting the synchronous clock to each processing module; and the processing modules are used for receiving clock signals output by the corresponding frequency multiplication modules and performing image processing according to the clock signals. The multi-screen display system consisting of the display processing equipment provided by the invention has the advantages of higher image display synchronicity and higher image display quality.

Description

technical field [0001] The present invention relates to the technical field of multi-screen display, in particular to a multi-screen display system and a device composing the multi-screen display system. Background technique [0002] With the development of the multi-screen display technology, the application of the multi-screen display technology becomes more and more extensive. In a multi-screen display system, it is often necessary to combine multiple display processing devices to display a complete picture synchronously. In order to realize the synchronous display of each of the display processing devices, generally the controller of the multi-screen display system The display processing device sends a synchronization instruction for executing the operation instruction, and each display processing device executes the synchronization instruction according to its own clock. [0003] Usually, after receiving the synchronization instruction, each display processing device o...
