Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] figure 2 A flow chart of a liquid crystal display control method according to an embodiment of the present invention is shown.

[0033] Such as figure 2 As shown, the control method includes:

[0034] Step S1: Perform decoding operation on the input video signal to obtain data corresponding to each pixel of the display panel. This data can be 6 bits, 8 bits or 10 bits.

[0035] Step S2: performing area division on the display panel. Different from simply dividing the display panel evenly into multiple areas in the prior art, the liquid crystal display control method according to the embodiment of the present invention is to set one or more on the backlight corresponding to the center of each divided area. light source. For direct-lit liquid crystal display devices, LED light sources are usually evenly distributed under the display panel, s...

Abstract

The invention relates to a liquid crystal display control method and system and a display device. The liquid crystal display control method includes the steps of carrying out decoding operation on an input video signal to obtain data corresponding pixels of a display panel; carrying out area division on the display panel, wherein positions, corresponding to centers of the divided areas, of a backlight source are provided with one or more light sources, and control signals of each area are calculated according to data of pixels of the corresponding area of the display panel; carrying out sub-area division on the areas according to light distribution in the areas, and adjusting the control signals of different sub-areas in a single area according to the different sub-areas in the single divided area; controlling the display panel and the backlight source according to the adjusted control signals.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display control method, system and display device. Background technique [0002] With the development of liquid crystal display technology, liquid crystal display devices such as liquid crystal televisions are gradually popular among consumers, and their sizes are also getting larger and larger, bringing people the latest visual enjoyment. [0003] Liquid crystal display is a passive display device, and the backlight source accounts for the highest proportion in the power consumption of the entire LCD TV. In order to reduce power consumption, for the direct type backlight source, the display panel is evenly divided into multiple areas in the prior art, and the display signal on the main chip of the liquid crystal display device is obtained by the control device, and the display signal in each area is analyzed by analyzing the display signal. The backlight sourc...
