A liquid crystal glass panel detection signal generation device and method

Abstract

The invention belongs to the technical field of liquid crystal panel detection, and discloses a liquid crystal glass panel detection signal generation device and method. The device includes a system clock module integrated in an FPGA chip, a module power supply module, an image generation module, an output timing generation module, a Signal generation module, output interface module and signal serialization output module; the method is based on its system, and the module power supply control signal for detecting the glass of the LCD panel is obtained according to the external LVDS signal or the internally generated multi-link RGB image, and the Mini‑LVDS clock signal, Mini-LVDS signal, and timing control TCON signal; it can be directly used to detect the display effect of the LCD glass panel integrated with the SOC, and can generate driving signals in different working modes through the upper layer settings to detect different LCD glass panels , suitable for mass inspection; provide human-machine interface and automatic control interface, high degree of automation; suitable for manual inspection or automatic inspection on the production line.

Description

technical field [0001] The invention belongs to the technical field of verification and testing of liquid crystal modules, and more specifically relates to a liquid crystal glass panel detection signal generation device and method, which display images through Mini-LVDS video signals and timing control signals. Background technique [0002] With the increasing popularity of liquid crystal display devices, people have put forward more demands on display devices, such as more portable, thinner, borderless full screen, hanging on the wall like a photo, more exquisite appearance, more powerful display effect and functions. For this reason, liquid crystal module manufacturers and equipment manufacturers have gradually developed system display technology. The original traditional display and display module are composed of backlight + liquid crystal glass (panel) + display driver chip + power supply chip. When a certain device displays an image, a central processing chip (CPU or MC...

Problems solved by technology

[0004] But at present, it is difficult for this new generation of display devices to be mass-produced. One of the reasons is the lack of image signals, timing control TCON signals, and various The power supply and power control signal are used to detect the display effect of the liquid crystal glass panel used in this type of display device, and can generate driving signals in different working modes through the upper layer settings to detect different liquid crystal glass panels. Testing equipment that can be used reliably and stably on the production line, and at a lower cost
