Screen saver control method and control system for a TFT liquid crystal screen

Abstract

The invention provides a screen saver control method and control system for a TFT liquid crystal screen. When the TFT liquid crystal screen is turned on, if the TV control command is not received within a predetermined time, the SOC of the core will send a signal to start the screen saver function to the logic board of the screen end. ; After the screen end logic board receives the signal to start the screen saver function, trigger the burn-in test board of the TFT liquid crystal screen to start the burn-in test function, control the liquid crystal screen to enter the screen saver state, and control to close other running application functions at the same time. The method and system disclosed in the present invention, through the present invention based on the traditional TV TFT LCD screen aging test function, replace the written aging picture from the W / R / G / B picture with the required resource picture, and then according to different screen aging tests The trigger method of the function is used to start this function module to realize the screen saver, and the trigger of the screen burn-in test function does not require all the modules of the core SOC to work, so it saves power consumption.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to a screen saver control method and control system for a TFT liquid crystal screen. Background technique [0002] With the development of technology and media, LCD TVs now have a screen saver function, which not only can promote the latest news and TV programs, but also has an advertising effect, bringing benefits to users and manufacturers respectively. But now the screen saver function of the LCD TV screen is implemented in the following way: under the home page menu, the core SOC (System on Chip, system-level chip) will not detect external remote control and key operations within a certain period of time, and will start the screen saver APP. The display screen plays some media resource images and presents them one by one. But this way of realizing through the screensaver APP is the same as watching the film source normally, the core of the TV is still in the normal work...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide users with a screen saver control method and control system for TFT LCD screens, which overcomes the problem that LCD TVs use screen saver APP for screen saver in the prior art, and the entire system is in normal operation. State, can not save the defect of power consumption
