Embodiment Construction

[0010] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0011] The present invention adopts the method of inserting a black picture in the blank time domain between two display pictures to solve the problem of smearing of the picture displayed on the liquid crystal screen. The specific method is: after the LCD screen displays a frame of pictures, in the blank time domain of the LCD screen line scanning, use the Gate IC (a chip used to provide the row switch of the LCD screen pixel array) to switch the odd-numbered lines of all the pixels of the LCD screen All open, the Source IC (used to provide the driving power of the LCD screen) will charge the black screen voltage to all odd-numbered rows of pixels. Charge the open pixel with the same polarity as the original pixel black screen or gray screen Gamma...

Abstract

The invention discloses a method for solving the smear problem of LCD pictures, wherein, black pictures are inserted in a blank time domain between two frames. By the way of inserting the black pictures in the line scanning blank time domain, the method helps fundamentally solve the image sticking problem while fast and dynamic pictures are displayed on LCD in the case of no change of system frequency of traditional drive and no addition of complexity of movable hardware route.

Description

technical field [0001] The invention discloses a driving method of a liquid crystal screen, in particular a method for solving the problem of smearing of the display screen of the liquid crystal screen. Background technique [0002] With the development of electronic technology, liquid crystal display technology is more and more widely used in people's daily life. At present, in the liquid crystal screen in the prior art, the voltage of each pixel of the liquid crystal screen is fixed during a face-changing display cycle, so that the liquid crystal molecules can move to obtain a certain light penetration to display the picture until the next picture cycle, and then Apply different speed-limiting voltages to change the light penetration of liquid crystal molecules and display different images. This kind of display method will have the problem of image sticking when displaying fast moving pictures, that is, picture smearing. Contents of the invention [0003] Aiming at the...
