Description

technical field [0001] The invention belongs to the field of display and testing of liquid crystal modules, in particular to a device for detecting the quality of MIPI video signals. Background technique [0002] The liquid crystal display module (Liquid Crystal Display Module, hereinafter referred to as the module) and its related liquid crystal display equipment (hereinafter referred to as the device) have been widely used, and because the MIPI (Mobile Industry Processor Interface) signal is stable and reliable , high transmission rate, and low power consumption, many modules and devices use this signal as a display interface for receiving video images. [0003] During the production, debugging and display process of the module and its equipment, it is necessary to generate a MIPI video signal through a video image signal source or a video adapter board (hereinafter referred to as the video source) to provide the source of the module display signal, so ensure that the vide...

Problems solved by technology

Operators of this detection method are not only prone to misjudgment, but it is difficult to locate the cause when a display problem occurs; and it is easily affected by human subjective recognition through human eyes. The operator is facing the image for a long time, and the eyes are very prone to fatigue, which will affect the detection. The result is affected; when the module is replaced, the test platform needs to be rebuilt, resulting in low efficiency and cumbersome operation
