no. 1 approach

[0038] see figure 1 , the first embodiment of the liquid crystal display driving method of the present invention includes the following steps:

[0039] S101: When it is detected that the backlight of the liquid crystal display is turned off, a display driving signal is generated before the backlight is turned on again, and the display driving signal is a display signal for reducing or avoiding distortion of liquid crystal molecules in the liquid crystal display.

[0040] Specifically, the user can actively press the sleep button to make the LCD screen enter the sleep state or the LCD screen automatically enters the sleep state, that is, when the screen of the LCD screen is displayed from normal to the backlight is turned off, a display driving signal is generated before the backlight is turned on again , the display driving signal is a display signal for reducing or avoiding twisting of liquid crystal molecules in the liquid crystal display.

no. 2 approach

[0045] see figure 2 , the second embodiment of the liquid crystal display driving method of the present invention includes the following steps:

[0046] S201: When it is detected that the backlight of the liquid crystal display is turned off, a display driving signal is generated before the backlight is turned on again, and the display driving signal is a display signal for reducing or avoiding distortion of liquid crystal molecules in the liquid crystal display.

[0047] S202: Before generating the display drive signal, judge whether the liquid crystal display is a normally black liquid crystal display; generating the display drive signal includes: if it is judged to be yes, then obtain a full black picture signal, and use the full black picture signal as a display drive signal; if the judgment is negative, then obtain a full-white picture signal, and use the full-white picture signal as a display driving signal.

Abstract

The invention provides a liquid crystal display screen driving method and a device thereof. The method comprises steps that when backlight of a liquid crystal display screen is detected to be turned off, a display driving signal is generated before backlight re-start, and the display driving signal is a display signal for reducing or avoiding distortion of liquid crystal molecules in the liquid crystal display screen; the liquid crystal display screen is driven through the display driving signal. According to the method, when backlight of the liquid crystal display screen is determined to be turned off, the display driving signal is generated before backlight re-start, pressure difference among liquid crystal molecules of upper and lower polar plates of the liquid crystal display screen is made to be the least through the display driving signal, so the distortion degree of the liquid crystal molecules is made to be the least, and a problem of screen flashing caused by liquid crystal polarization can be reduced or avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display driving method and a device thereof. Background technique [0002] After the LCD screen enters dormancy, if the charges stored in the LCD panel cannot be completely released, the liquid crystal molecules of the LCD screen are still in a twisted state, and the liquid crystal molecules are prone to polarization, resulting in screen flicker. [0003] At present, there is no better solution to the flickering problem of this kind of LCD screen when it wakes up after entering sleep. Generally, it is made by improving the glass, but the cycle is very long, or let the LCD screen sleep for a longer time, and the liquid crystal molecules Return to normal and wake up again. Contents of the invention [0004] The invention provides a method and device for driving a liquid crystal display to solve the technical problem of twisting liquid crystal molecules in the l...
