Method, device and liquid crystal display for reducing dynamic crosstalk of shutter type 3D liquid crystal

Abstract

A method used for reducing shutter 3D liquid crystal dynamic crosstalk, comprising: receiving digital information of a left eye image and of a right eye image of the current frame; comparing if the combination of left and right eye grayscale values of pixel points of the current frame is identical to the combination of left and right eye grayscale values of corresponding positions of the previous frame; adjusting, on the basis of a grayscale comparison chart corresponding to a scan line where the pixel points are at, the grayscale values of the image of one of the eyes of the pixel points that have different left and right eye grayscale values in the comparison result, adjusting the grayscale values of the pixel points of the image of one of the eyes of the current frame to target grayscale values corresponding to the pixel points; displaying the image of one of the eyes that have all of the scan lines adjusted in grayscale values of the current frame, and the image of the other eye that has not been adjusted of the current frame. Also disclosed are a device used for reducing the shutter 3D liquid crystal dynamic crosstalk and a corresponding liquid crystal display device. The method or device used for reducing the shutter 3D liquid crystal dynamic crosstalk allows for significant elimination or reduction of crosstalk between the left and right eyes.

Description

technical field [0001] The invention relates to a shutter type 3D liquid crystal display technology, in particular to a method and device for reducing the dynamic crosstalk of a shutter type 3D liquid crystal and a corresponding liquid crystal display. Background technique [0002] The working principle of the shutter type 3D liquid crystal display is to make the liquid crystal panel display the left eye image and the right eye image in sequence, and at the same time control the closing of the shutter glasses so that the left eye can see the left eye image, and the right eye can see the right eye image. If the left eye sees the right eye image and the right eye sees the left eye image, the human eye will experience crosstalk. [0003] Due to the hold characteristic of liquid crystals, there is a certain response time, which causes the liquid crystal panel to always retain the unresponsive image of the previous frame when displaying a frame of image. If the liquid crystal pan...

Problems solved by technology

[0005] The inventor found that the technology of backlight scanning can reduce the display crosstalk to a certain extent, but the effect is limited and the cost is high; the method of compressing the transmission time of each frame of image data is still limited in reducing the display crosstalk due to the limitation of the compression rate; The dynamic drive of the left and right eyes at the same time will increase the static left and right eye crosstalk

Therefore, in general, the existing technology is not effective in reducing the crosstalk problem of shutter-type 3D LCDs.
