Embodiment Construction

[0026] The method for configuring the parameters of the LCD screen of the present invention is mainly to store all parameters related to the LCD screen in the EEPROM (Electrically Erasable Read-Only Memory) of the machine according to the predetermined data structure. In the initial stage of operation, the data stored in EEPROM is read out, and then the type of the screen is automatically identified, and the parameters of the screen are configured during the subsequent running of the program according to the type of screen and the read data. The present invention will be described in detail below in conjunction with a preferred embodiment.

[0027] Please refer to shown in Fig. 3, the configuration method of liquid crystal screen parameter of the present invention comprises three main processes: one, the initialization of CPU and EEPROM; Two, read liquid crystal screen parameter and gamma data table; Three, write gamma curve value Enter the SCALER chip. The above process is d...

Abstract

The present invention provides a collocation method of liquid crystal screen parameters. Said method includes the following steps: in EEPROM presetting at least two screen-type selection parameters, in which one presentation screen parameter is stored in EEPROM, other presentation screen parameters are solidified in program; fetching screen-type selection parameters in EEPROM, judging storage position of every screen parameter; obtaining screen parameter from storage position of screen parameter and gamma list; according to obtained screen parameters collocating liquid crystal screen, and initializing liquid crystal screen control chip; and restoring gamma culve and writing gamma culve value into liquid crystal screen control chip.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display screen, in particular to a method for storing liquid crystal screen parameters in EEPROM (Electrically Erasable Read-Only Memory) and configuring the liquid crystal screen parameters during start-up operation. 【Background technique】 [0002] In today's world, the rapid development of electronic technology has brought an earth-shaking technological revolution to the color TV industry. LCD TVs have begun to enter the homes of ordinary people, especially ultra-light, ultra-thin, high-definition LCD flat-panel TVs are increasingly favored by consumers. As the market share continues to increase, the competition among various brand manufacturers is in full swing. [0003] As a key factor in LCD flat-panel TVs, LCD screens occupy a considerable part of the price of LCD TVs, and the price fluctuations of LCD screens also bring uncontrollable risks to the production costs of complete machine manufacturers . ...
