Abstract

A regional digital gain controller, including a digital gain control unit, receives input image data to obtain enhanced image data; a sub-pixel coordinate determination unit receives multi-component color data of the input image data, and obtains the composition color data according to Coordinates; a space gain value unit for generating the space gain values ​​of the constituent color data according to the coordinates; and a multiplier for multiplying the enhanced image data by the corresponding space gain values ​​to generate the compensation image data. The technical solution of the invention can improve the uniformity of the color temperature of the liquid crystal display.

Description

technical field [0001] The invention relates to a display control system suitable for liquid crystal displays, in particular to an area digital gain controller. Background technique [0002] A liquid crystal display (LCD) is a type of flat-panel display, which uses liquid crystal molecules to control and modulate the intensity of light to display images. Liquid crystal displays can be applied to various electronic devices, such as televisions, computers, mobile phones, etc., and can be used in indoor or outdoor occasions. [0003] The liquid crystal display includes a plurality of pixels arranged in a matrix, and the display of images is controlled by control elements (such as thin film transistors (TFTs)). However, due to the electrical or optical manufacturing variation of the device, non-uniform brightness will be formed, resulting in a phenomenon of non-uniform brightness (mura) where some pixels are brighter or darker. [0004] In order to improve such display unevenn...
