Problems solved by technology

In terms of improving the response time of liquid crystals, the general method used in the industry is to accelerate the drive (Over Drive, OD). The principle is to give an excessive driving voltage to accelerate the rotation of the liquid crystal, and then return to the expected voltage, so that the liquid crystal can be reduced. response time, however, the main disadvantage of this approach is that it cannot be used when the pixel is at its brightest
In terms of improving the steady-state backlight, the general improvement methods used in the industry include inserting black screens, inserting grayscale screens, and dynamic compensation, etc., but the above methods will be accompanied by disadvantages such as brightness reduction, screen flickering, and huge calculations. Therefore, at present, Still no best solution

Abstract

The invention provides a method and a device for processing an image. The method comprises the steps of detecting one edge of image inputting data to generate an image inputting data edge detecting result, determining an adjustment coefficient which corresponds to a target pixel according to the image inputting data edge detecting result and adjusting an output gray value of the target pixel according to the adjustment coefficient.

Description

technical field [0001] The invention relates to an image processing method and device applied to a display device, in particular to a method and device for reducing motion blur of a liquid crystal display. Background technique [0002] When a liquid crystal display (LCD) displays dynamic images, there will be blurred afterimages on the edges of objects in the images. There are two main reasons for this: one is that the liquid crystal response time (Responsetime) is insufficient, and the other is that the steady-state backlight (Hold type) caused by the discontinuity of human eye tracking. [0003] The principles of liquid crystal response time and steady-state backlight are well known to those skilled in the art, so details will not be repeated here. In terms of improving the response time of liquid crystals, the general method used in the industry is to accelerate the drive (Over Drive, OD). The principle is to give an excessive driving voltage to accelerate the rotation o...
