Abstract

The invention discloses a liquid crystal module. The liquid crystal module comprises a backlight source and a liquid crystal panel which are oppositely arranged, a liquid crystal light valve is arranged between the backlight source and the liquid crystal panel, the liquid crystal light valve is provided with a plurality of sub-areas with variable electrotransmittance, and the light transmittance of each sub-area on the liquid crystal light valve is adjusted according to the display content of the liquid crystal panel. According to the liquid crystal module, local brightness adjustment can be achieved, and the thickness of the module is small. The invention further discloses a method for improving the contrast ratio of the liquid crystal module.

Description

technical field

[0001] The invention relates to display technology, in particular to a liquid crystal module and a method for improving the contrast of the liquid crystal module. Background technique

[0002] With users' pursuit of display effects, HDR display has become an essential function of high-end display devices. HDR display improves the overall contrast through local dimming of the display area, while the LCD module mainly realizes the local brightness adjustment function by adjusting the brightness of each LED light in its backlight, although the sample display effect is very good , but due to issues such as mass production or structural compatibility in actual projects, it is difficult to use it in practical applications, especially for projects that require total thickness. Contents of the invention

[0003] In order to solve the shortcomings of the above-mentioned prior art, the present invention provides a liquid crystal module, which can realize local brigh...
