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

Abstract

The invention belongs to the fields of display and testing for liquid crystal modules, and particularly relates to a device for quality detection of TTL (transistor-transistor logic) video signals. The device includes a TTL transmission module, an RGB (red, green, and blue) data detection module and a detection control module, wherein the TTL transmission module is used for receiving the TTL video signals, terminating the received TTL video signals, and detecting the electrical characteristics of the terminated TTL video signals; the RGB data detection module is used for detecting image data of the TTL video signals; the detection control module is used for sending parameters and control signals. The device achieves the detection of the TTL video signals generated by a video source, has the advantages of high simplicity in operation, high economization and practicality, high integration level, as well as high work reliability and anti-jamming capability, and can improve the detection reliability and efficiency for a TTL liquid crystal module and reduce the equipment cost and production cost of the TTL liquid crystal module.

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 TTL 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 equipment) have been widely used, and because the TTL (Low-Voltage Differential Signaling, low-voltage differential signal) 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 TTL video signal through the video image signal source or video adapter board (hereinafter referred to as the video source) to provide the source of the module display...
