Abstract

The invention relates to an LCD polarity-overturn control method and an LCD display terminal. The method comprises the steps that 1) setup codes of a display screen respectively corresponding to different polarity overturn modes, including a frame overturn mode, a row overturn mode, a column overturn mode and a point overturn mode, are written in a memory of the LCD display terminal; a terminal processor detects a polarity-overturn mode switching instruction, and reads the setup code of the display screen in the instructed polarity mode into an LCDC (Liquid Crystal Display Controller) register; and according to the setup code of the display screen, an LCDC sends resetting signals to an LCD driver, and implements initialization of the display screen in the instructed polarity overturn mode. When the current overturn mode of the display screen causes failure of the display screen, another liquid-crystal molecule overturn mode can be directly turned to, thereby avoiding heavy load caused by replacement of control software, improving user experience, and decreasing maintenance cost of a manufacturer.

Description

technical field

[0001] The invention relates to the driving of a liquid crystal display, in particular to a method for controlling polarity inversion of a liquid crystal display and a display terminal. Background technique

[0002] Because the liquid crystal molecules of the liquid crystal display have a characteristic, they cannot be fixed at a certain voltage all the time. Otherwise, even if the voltage is canceled for a long time, the liquid crystal molecules will no longer be able to change due to the change of the electric field due to the destruction of the characteristics. turning, so every once in a while the voltage has to be brought back to it's original state. In order to ensure the activity of its liquid crystal molecules, the existing liquid crystal display screen will flip the liquid crystal molecules at a certain frequency when displaying the picture, so that the liquid crystal molecules will not be fixed to a certain direction, resulting in loss of activity, ...
