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

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0034] Such as Figure 1-5 Shown, the method for the MIPI video signal that detection video source of the present invention produces comprises the following steps:

[0035] Set the control parameters in the upper PC. The PC control parameter settings are the same as the detected video source. The control parameters include: MIPI receiving matching parameters, MIPI electrical parameter references (maximum voltage, minimum voltage, overshoot, undershoot, current, etc.), MIPI screen opening instruction set, MIPI data LANE number setting and MIPI data 6 / 8 / 10bit setting, the horizontal resolution and vertical resolution of the image under test (also the resolution of the original image). The above PC control parameters are sent to the...

Abstract

The invention belongs to the fields of liquid crystal module displaying and testing, and particularly relates to a method for detecting MIPI video signals generated by a video source. The method comprises the steps that firstly, the electrical characteristics of the MIPI video signals are detected, and an MIPI electrical detection result is output; secondly, the MIPI video signals are received, and MIPI HSs are converted into RGB video signals; thirdly, if the MIPI electrical detection result shows that the quality of the MIPI video signals is up to standard, each frame of RGB data in the RGB video signals are cached, then the cached RGB data are sequentially compared with original image data to be detected, and an image data detection result is output. According to the method, the MIPI video signals generated by the video source can be detected, operation is easy, economy and practicality are achieved, the integration level is high, work is reliable, the anti-interference capability is high, the reliability and efficiency of detecting an MIPI liquid crystal module can be improved, and the equipment cost and production cost of the MIPI liquid crystal module can be lowered.

Description

technical field [0001] The invention belongs to the field of display and testing of liquid crystal modules, in particular to a method for detecting MIPI video signals generated by video sources. Background technique [0002] The use of liquid crystal display modules (Liquid Crystal Display Module, hereinafter referred to as modules) and related liquid crystal display devices (hereinafter referred to as devices) has become very common, and at the same time due to the stable signal of MIPI (Mobile Industry Processor Interface) 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 ...
