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.

The invention discloses a method for reducing shutter-type 3D (three-dimensional) liquid-crystal display crosstalk. The method includes receiving digital information of an original left-eye image and a right-eye image; comparing whether gray scales of various corresponding pixel points in the digital information of the left-eye image and the digital information of the right-eye image in each scanning row are identical or not; adjusting gray scale values, identical after comparison, of the pixel points of the left-eye image and the right-eye image according to a first gray scale comparison table of the current scanning row of the pixel points of the images; adjusting gray scale values, different after comparison, of the pixel points of the left-eye image and the right-eye image according to a second gray scale comparison table of the current scanning row of the pixel points of the images; and transmitting the digital information of the left-eye image and the right-eye image after the gray scales of all scanning rows are adjusted. The invention further discloses a device for reducing shutter-type liquid-crystal display crosstalk and a corresponding liquid crystal display. By the method, the device and the liquid crystal display in the embodiment of the invention, crosstalk of the left eye and the right eye can be evidently eliminated or reduced.
Description
technical field [0001] The present invention relates to a shutter type 3D liquid crystal display technology, in particular to a method and device for reducing the crosstalk of a 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 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 cry...
