Liquid crystal display device

Abstract

A Liquid crystal display device comprises a backlight module and a control unit, wherein the control unit is used for controlling the backlight module to regulate the opening time and the light intensity of a backlight light source in terms of the brightness difference between a left eye image and a right eye image, so as to balance the brightness of the left eye image and the right eye image and improve crosstalk disturbance. The liquid crystal display device regulates the opening time and the light intensity of the backlight light source in terms of the brightness difference between the left eye image and the right eye image, so as to balance the brightness of the left eye image and the right eye image and reduce crosstalk disturbance.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and in particular to a liquid crystal display device capable of balancing the brightness of left and right eyes and reducing crosstalk. Background technique [0002] figure 1 is a schematic diagram of a known three-dimensional display system. The 3D display system 100 includes a liquid crystal display 102 (which includes a backlight module and a polarizer) and a liquid crystal polarizing panel 104 , wherein the liquid crystal polarizing panel 104 is disposed in front of the liquid crystal display 102 . The liquid crystal display 102 can emit images with a specific polarization angle (for example, 45 degrees), and the liquid crystal polarizing panel 104 can adjust the polarization angle of the images emitted by the liquid crystal display 102 (for example, adjust it to 135 degrees) according to a polarization control signal. In this way, the liquid crystal display 102 and the liquid crys...

AI Technical Summary

Problems solved by technology

Since the liquid crystal transition characteristics in the liquid crystal polarizing panel 104 are similar to a resistance capacitor (Resistance Capacitance, RC) charging state, that is, the liquid crystal will slowly rotate for a certain period of time before reaching a complete transition state. When the liquid crystal has not completed the transition state, The polarization angle of the light is not optimal, resulting in crosstalk between the images of the left eye and the right eye (Crosstalk)

In addition, since the liquid crystal returns to its original state faster than the speed at which it is driven by a voltage, the image for the left eye does not have the situation that the polarization angle of the light does not reach the optimal angle like the image for the right eye, but the difference It will cause the viewer to feel the brightness imbalance of the left and right eye images
