Embodiment Construction
[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0035] In order to improve the stability of the TV Scaler motherboard, before the TV or its internal Scaler motherboard goes to the market, it is necessary to perform a performance test on the TV Scaler motherboard to ensure the stability of the TV Scaler motherboard.
[0036] The existing Scaler main board detection method is to manually detect the appearance of the Scaler main board, and to detect the built-in interfaces on the Scaler main board, such as audio interface, USB interface, HMDI interface, AV interface, RF interface and so on. At present, the required Scaler motherboard test items can only be tested one by one manually. On the one hand, the ex...

The invention discloses a Scaler mainboard detection method adaptive to a liquid crystal panel, and the method comprises the steps: powering on a Scaler mainboard, starting a Boot guide program, and calling a preset V-By-One standard screen parameter index; the Scaler mainboard loads and writes a preset V-By-One standard screen parameter into a main chip bottom layer register so as to load a kernel program to output a picture; the signal detection module detects and collects V-By-One signals output by the Scaler mainboard, and the PC controls the host to analyze the accuracy of image data; after interface detection is completed, the PC control host sends a serial port screen index number instruction to the Scaler mainboard; and the Scaler mainboard stores a corresponding screen index number based on the serial port instruction, sets the screen index number as a startup screen index, and then shuts down the Scaler mainboard. The mainboard detection device has a good detection effect on various mainboards and ports of the mainboards, and is low in production cost and simple and convenient to use.
Description
technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to a detection method for a Scaler main board adapted to a liquid crystal panel. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the vigorous development of flat-panel displays has been driven. Among them, liquid crystal display LCD is based on its advantages of low voltage operation, no radiation scattering, light weight and small size. [0003] Due to the development of LCD panels towards high resolution, high refresh rate, and high bit count, the data transmitted between the timing control chip (TimingControl, TCON IC) and the driver chip (DriverIC) has increased significantly. [0004] With the development of society, users have more and more demands for ultra-high-definition programs. UHD (Ultra High Definition) screens (resolution 3840*2160) are becoming more and more common...
