LCD TV backlight sequence control method and system

Abstract

The invention relates to liquid crystal television techniques. The invention solves a problem that backlight sequential controlling of existing different screen liquid crystal televisions needs to be realized through different kinds of backlight sequential control software, and provides a liquid crystal television backlight sequential control method and a system. The technical scheme can be summarized as: backlight sequential control parameters of liquid crystal televisions of different models are pre-stored in liquid crystal televisions; in production debugging, backlight sequential parameters matched with the liquid crystal televisions are selected from the backlight sequential control parameters through a liquid crystal television processing system, and the backlight sequential parameters are set to be preset screen parameters; and in usage, a liquid crystal television system reads the preset screen parameters and outputs sequential control signals to a liquid crystal television display module according to the preset screen parameters. The beneficial effects of the liquid crystal television backlight sequential control method and the system of the invention are that: production management and design maintenance are provided with convenience, and the liquid crystal television backlight sequential control method and the system are applicable to shutter-type 3D liquid crystal televisions.

Description

technical field [0001] The invention relates to liquid crystal television technology, in particular to the technology of liquid crystal television backlight control. Background technique [0002] 3D liquid crystal display technology can be divided into two categories: glasses type and naked eye type. Among them, glasses type 3D technology can be divided into color difference type, polarized light type and active shutter type. Among them, the active shutter type 3D technology needs to control the backlight of the LCD TV. Control to improve the 3D image display effect of the TV. Due to the limitation of the physical properties of the liquid crystal material in the LCD panel, the response speed of the LCD TV is relatively slow. The timing of field scanning controls the on and off of the backlight to reduce the crosstalk between the left and right eyes of 3D, and in order to achieve better 3D display effect, it is also necessary to control the backlight by partition. LCD screen...

AI Technical Summary

Problems solved by technology

At present, the backlight timing control of LCD TVs with different screens requires different backlight timing control software to realize, which is not conducive to production management. At the same time, special software personnel are required for daily design and maintenance, which increases the cost of manufacturing and design and development.
