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

A method used for reducing shutter 3D liquid crystal display crosstalk, comprising: receiving digital information of an original left eye image and of an original right eye image (S60); comparing if the grayscale values of corresponding pixel points in the digital information of the left eye image and in the digital information of the right eye image are identical (S61); adjusting the grayscale values of the pixel points of the left and right eye images that are identical in the comparison result on the basis of a first grayscale comparison chart of a current scan line of the image pixel points (S62); adjusting the grayscale values of the pixel points of the left and right images that are different in the comparison result on the basis of a second grayscale comparison chart of the current scan line of the image pixel points (S63); and, transmitting outwards the digital information of the left eye image and of the right eye image having all of the scan lines adjusted in grayscale values (S66). Also disclosed are a device used for reducing the shutter 3D liquid crystal display crosstalk and a corresponding liquid crystal display device. The device and method allow for elimination or reduction of crosstalk between the left and right eyes.
Description
technical field [0001] The present invention relates to shutter-type 3D liquid crystal display technology, in particular to a method and device for reducing crosstalk of shutter-type 3D liquid crystal display and a corresponding liquid crystal display. Background technique [0002] The working principle of the shutter-type 3D liquid crystal display is to make the LCD 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 feel the crosstalk phenomenon. [0003] Due to the hold characteristic of liquid crystal, it has a certain response time, so that the LCD panel will always leave a frame of unresponsive image when displaying one frame of image. How people adjust the synchronization of shutter glasses, ...
