Liquid crystal display and driving method

Abstract

The invention provides a liquid crystal display and a driving method, in particular to application image segmentation technology which comprises the following steps: segmenting image data into a plurality of image blocks, carrying out image analysis on the image blocks, regulating low gray-scale image data of the image blocks into high gray-scale image data, outputting a backlight control signal to a backlight control module, controlling a corresponding backlight module block of the image block by the backlight control module, and darkening the backlight of the image block to reduce the problem of color migration of the image block.

Description

technical field [0001] The invention relates to a liquid crystal display and a driving method, in particular to an application of image segmentation technology to adjust image blocks belonging to high color shift areas to reduce color shift. Background technique [0002] see figure 1 , which is a system architecture diagram of a known liquid crystal display. Such as figure 1 As shown, the liquid crystal display 100 with a resolution of 1024*768 is taken as an example for the following description. The liquid crystal display 100 has 1024 rows of red pixels, 1024 rows of green pixels and 1024 rows of blue pixels for driving. There are 1024*3 data lines and 768 scan lines in total. The data lines and the scan lines are respectively driven by the data driver 110 and the scan driver 120 . Under the control of the data control signal Control_D output by the controller 130, the data drivers 110 and the scan drivers 120 sequentially receive multiple pieces of pixel data PD trans...
