Abstract

The invention discloses a three-dimensional (3D) liquid crystal display driving method which includes the following steps: S1, generating at least two scanning clock signals in a data signal output period, outputting corresponding effective data area signals of a left eye and a right eye after processing input image signals; S2, outputting at least two scanning clock signals synchronously; and S3, driving the liquid crystal panel to conduct at least two lines of scanning synchronously and displaying the processed image signals according to the at least two scanning clock signals. The invention further discloses a display system which comprises a time schedule controller and a grid driver. The time schedule controller comprises a STV, CKV and OE processing circuit which is used for processing the input image signals. The grid driver is used for driving the liquid crystal panel to conduct at least two lines of scanning synchronously. The 3D liquid crystal display driving method and the 3D liquid crystal display system reduce liquid crystal scanning time and lower requirements of 3D display refreshed at high speed for the liquid crystal panel and a chip.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a 3D liquid crystal display driving method and a 3D liquid crystal display system. Background technique

[0002] like figure 1 As shown, the traditional 120Hz driving 3D technology without backlight scanning opens the glasses to watch the 3D effect in the blank (Blank) area after the image scanning is completed, but this has the problem that the flipping time of the upper and lower liquid crystals of the LCD panel is inconsistent and the viewing time is short.

[0003] Different from the above-mentioned traditional 120Hz 3D SG control method without backlight scanning, there is also a 120Hz 3D display method using backlight scanning in the prior art. Its circuit control block diagram is as follows figure 2 Shown: The motherboard gives 60Hz signal LVDS (low voltage differential signal) (left, right, up and down, row interleaving, etc.), and the timing controller ...
