Abstract

The invention provides a backlight scanning system and method based on shutter type display. The backlight scanning system comprises a main chip, an MCU and a T-CON driving module, wherein the MCU and the T-CON driving module are respectively connected with the main chip, the T-CON driving module is connected with the MCU, the MCU is respectively connected with a 3D glass driving module and a power module, and the MCU drives a modular back lamp through the power module. In a shutter type 3D liquid crystal display television applying a sectional backlight scanning mode, through the systematic combination of the main chip, the MCU, a power supply, modules and the like, when a liquid crystal unit refreshes data, sectional backlight scanning display is carried out synchronously, crosstalk of pictures is avoided, and a better 3D display effect is achieved.

Description

technical field

[0001] The present invention relates to a backlight scanning system and method based on shutter display, in particular to a backlight scanning system and method suitable for liquid crystal 3D display based on shutter display. Background technique

[0002] With the development and maturity of liquid crystal 3D display technology, the shutter type is more and more favored by consumers because of its high-definition display and wide-angle viewing range. Its main principle is to divide an image into two images for the left eye and the right eye. With the cooperation of 3D glasses, the left eye and right eye of the viewer can watch the corresponding image in turn, and the image is reconstructed in the brain. To achieve a 3D effect. However, the shutter-type 3D has strict requirements on the timing of the left and right eye images. Under the original backlight display mode, image crosstalk (crosstalk) is easy to occur, which affects the subjective effect. Conten...
