Abstract

The invention discloses a backlight control method of a three dimensional (3D) liquid crystal display device. The method comprises that a liquid crystal display and backlight units are divided into N corresponding regions in a transverse direction, wherein the N is more than or equal to four; scanning time of each frame image is set for T1 and retention time is set for T2 in the alternate display process of a left eye image and a light eye image of the liquid crystal display and the scanning time of each region on the liquid crystal display is T1 / N; the retention time of the backlight units is set for T4 after the backlight units are opened, wherein the backlight units correspond to each region; the left eye image and the right eye image are displayed on the liquid crystal display alternately, wherein the left eye image and the right eye image have a certain parallax; and opening time of the backlight units is no earlier than the time of the current image of the region accomplishing scanning and response, wherein the backlight units correspond to each region. The backlight control method of the 3D liquid crystal display device can solve the crosstalk problem of the left eye image and the right eye image when field frequency is not improved. The backlight control method of the 3D liquid crystal display device can improve the luminance of a display frame.

Description

technical field [0001] The invention relates to the technical field of 3D display device manufacturing, in particular to a backlight control method for a 3D liquid crystal display device. Background technique [0002] Stereoscopic display devices are also called 3D display devices, which mainly obtain two images of the same object at different angles or at different times according to the principle of human vision, and project these two images into the left and right eyes of people respectively. Therefore, the images in the left and right eyes of a person have a certain parallax, and then the images in the left and right eyes with parallax are synthesized by the brain to produce depth vision, that is, the display effect of forming a three-dimensional image. [0003] At present, when a 3D display device displays a stereoscopic image, it is mainly realized by using a 3D time-sharing display technology. When a 3D display device adopts a liquid crystal screen, due to the inhere...
