Device and method for switching LVDS video signals from one way to multiple ways

Abstract

The invention discloses a device and method for switching LVDS video signals from one way to multiple ways, comprising a man-machine interface module, an LVDS video receiving module, a synchronizing module, a video decoding module, an LVDS image data caching module, an image resolution detection module and multiple LVDS video output modules; the method is based on the device. An LVDS image time sequence is rebuilt on every local LVDS video output module according to one way of LVDS video signals; multiple ways of LVDS image data are output from every local LVDS video output module to a module to be tested according to the time sequence; the LVDS video signals are switched from one way to multiple ways; the method is applicable to verify middle and large scale modules; every way of LVDS video signals are output simultaneously independently; the parameters can be adjusted independently; and the method is applicable to carry out simultaneous dot screen verification to a number of modules with the same resolution and different characteristics in different working conditions.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and more specifically relates to a device and method for converting single-channel to multiple-channel LVDS video signals. Background technique [0002] LVDS liquid crystal modules have been widely used in various fields. With the increase of demand for different modules, in order to ensure the quality of the modules, the verification of the modules is particularly important; because the test verification of the modules requires the use of image signal sources to generate reference images , and an existing image signal source often can only generate one or several reference images; for large-scale module testing, a large number of reference image signal sources are required, and the cost of image signal sources is high, and it cannot be realized in Simultaneous testing of modules with different characteristics under various tested environments leads to lower production efficiency and hi...
