Abstract

The embodiment of the invention relates to a method used for realizing restraint of screen tearing. The method comprises: the backlight is turned on when the power is on so as to output panel signals of an LCD; an electric source module is controlled to supply power to a panel signal processing module after the panel signals are stable, so as to display a start-up picture by a display screen. The embodiment of the invention further relates to a system used for realizing restraint of screen tearing. By adopting the method and the system of the embodiment of the invention, the electrifying time sequence of the display screen can be controlled, namely, the backlight is turned on when the power is on; the panel signals of the LCD are then output; the electric source of the panel signal processing module is turned on after the panel signals are stable so as to supply power to the LCD panel signal processing module and display the picture, thereby effectively restraining 'screen tearing' and improving visual effect and product quality; moreover, an independent electric source module is adopted to supply power to the panel signal processing module, thus the electric source is more stable.

Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a method and system for realizing blurred screen suppression. Background technique

[0002] Human-machine interface is an embedded computer product, mainly used as the control and display terminal of industrial production automation equipment, and LCD (Liquid Crystal Display, liquid crystal display) is widely used for its small size, light weight and clearer display screen. Applied to the human-machine interface.

[0003] Wherein, in the LCD, the LCD (Liquid Crystal Display, Liquid Crystal Display) controller is used to control the display of the LCD screen (panel), and the LCD controller is controlled by the MCU (Microprocessor). At the moment when the LCD is powered on, the reset of the MCU has not been completed. At this time, it cannot control the LCD controller, which will cause the address, data management, and read-write control of the display buffer to be co...
