Embodiment Construction

[0014] see figure 1 , is a schematic diagram of the circuit structure of a preferred embodiment of the liquid crystal display 1 of the present invention. The liquid crystal display 1 includes a liquid crystal display panel 10 , a scan driving circuit 20 , a data driving circuit 30 , an interpolation processor 50 and an overdrive processor 40 .

[0015] The interpolation processor 50 is used to receive the image data of each frame, and generate a first subframe interpolation data and a second subframe interpolation data according to the grayscale of the image data of each frame, and convert the first subframe The interpolation data and the second subframe interpolation data are output to the overdrive processor 40 . The interpolation processor 50 includes a black insertion processor 53 and a gray insertion processor 55 .

[0016] The overdrive processor 40 is used to receive the image data of each frame, the first subframe interpolation data and the second subframe interpolat...

Abstract

The invention relates to a liquid crystal display and a driving method thereof. The liquid crystal display comprises a controller and a data driving circuit, wherein the controller is used for receiving image data. First subframe interpolated data and second subframe interpolated data are generated firstly according to the current image data and then a first subframe overdrive gray scale and a second subframe overdrive gray scale are output to the data driving circuit according to the first subframe interpolated data, the second subframe interpolated data and the image data of a previous frame. The liquid crystal display effectively improves the incomplete image phenomenon and has good display quality.

Description

technical field [0001] The invention relates to a liquid crystal display and a driving method thereof. Background technique [0002] Liquid crystal displays are widely used in modern information equipment such as televisions, notebooks, computers, mobile phones, and personal digital assistants because of their advantages such as light weight, small size, and low power consumption. However, liquid crystals are viscous substances, so the response time of liquid crystal displays is generally longer, and since liquid crystal displays usually use a steady-state (Hold Type) driving method, when they are used in dynamic display, it is easy to be affected by the response speed. Insufficient image will cause afterimage phenomenon, affecting the quality of dynamic images. [0003] A method for solving the afterimage phenomenon in liquid crystal display dynamic display is called dynamic impulse driving (Dynamic impulse driving), also known as dynamic gray interpolation (Super Impulse)...
