Embodiment Construction

[0033] The technical solution provided by the present invention is to separate the screen configuration parameters of the flat panel display (hereinafter referred to as the screen configuration parameters) from the source code of the screen configuration software, and store them separately in a non-volatile random access memory (NVRAM). The non-volatile memory is in a hardware write-protected state during normal operation, ensuring that the screen configuration parameters will not be accidentally rewritten. When the screen configuration parameters are updated, the screen configuration parameters separately stored in the non-volatile random access memory are written through the computer, and the screen configuration parameters are updated. In this way, the hardware circuit board and software are not directly related to a specific flat panel display, but can adapt to various types of displays by modifying the stored screen configuration parameters, thereby maximizing the flexibil...

Abstract

The invention provides a method for matching a screen of a flat-panel display, comprising the following that: a. a screen matching parameter of the flat-panel display is obtained from a specification of the flat-panel display and is inputted to a computer; b. the screen matching parameter is written to a screen matching parameter memory of the screen matching system through the computer; and c. when the screen matching system is started, the screen matching parameter is read from the screen matching parameter memory to finish the screen matching flow. The technical proposal ensures that a hardware circuit board and software are not directly linked to a specific LCD panel and are suitable for various LCD panels by modifying the stored screen matching parameter, reduces the degree of coupling of the screen matching parameter of the flat-panel display with a software source code, realizes the separation of the screen matching parameter of the LCD panel from the software, reduces the workload of the detection and the test in the process of changing the flat-panel display, and improves the production efficiency.

Description

technical field [0001] The invention relates to the production and testing technology of television, in particular to a method and system for distributing screens of flat-panel televisions. Background technique [0002] With the advent of the flat-panel era, like the early CRT piping, the screen distribution of flat-panel TV displays has become a key link in R&D and production, and has become an important factor affecting capital turnover and production efficiency. [0003] Since different screens have different control sequences, including power-on sequence, signal sequence, signal parameters, signal format, etc., the process of screen configuration is to input these special parameters of the screen into the TV system program, so that the TV system can output suitable screens. control signal. [0004] The existing screen configuration process is: the hardware personnel provide samples of the new screen, and ensure that the hardware connection and power supply are normal, a...
