Embodiment Construction

[0056] A liquid crystal display device and an image display method thereof according to preferred embodiments of the present invention will be described below with reference to related drawings.

[0057] First, please refer to Figures 5 to 7E is shown to illustrate an image display method of a liquid crystal display device according to a preferred embodiment of the present invention.

[0058] Such as Figure 5 As shown, an image display method of a liquid crystal display device according to a preferred embodiment of the present invention is used to drive a plurality of pixels when sequentially displaying a first frame and a second frame, and the image display method includes Steps S01-S04.

[0059] In step S01 , a gray level difference between the first viewing frame and the second viewing frame is detected to determine a change of a driving mode between the first viewing frame and the second viewing frame.

[0060] In step S02 , according to the change of the driving mode...

Abstract

The invention discloses an image display method of an LCD, which is used for driving a plurality of pixels when a first vision frame and a second vision frame are sequentially displayed. The method includes the following steps: a gray-scale difference between the first vision frame and the second vision frame is detected to judge the change of a driving mode between the first vision frame and the second vision frame; according to the change of driving modes, the quantity proportion of the pixels driven by a dynamic mode and a static mode is regulated when the second vision frame is displayed; and a plurality of gray-scale data corresponding to the pixels are regulated when the second vision frame is output. The imaging display method can avoid the sudden and severe change of the brightness of images when the driving modes are changed so as to lead users to have no feeling of the fluctuation of the images so as to further enhance the quality of the LCD and the image display.

Description

technical field [0001] The present invention relates to a liquid crystal display device and its driving method, in particular to a liquid crystal display device using black (gray) insertion technology and its image display method. Background technique [0002] In order to enhance the display effect of the liquid crystal display device, the image data pulse is often shortened by adding a sub-frame, which is called a pulse-like liquid crystal display technology. The common one in the prior art is to add a normal The normally black sub-viewbox can be called black insertion or gray insertion technology. [0003] In the image display method of the liquid crystal display device in the prior art, the pixels on the display surface are driven in the same view frame in a unified dynamic / static mode according to the dynamic / static characteristics of the view frame, that is, when the pixels are to be driven in the dynamic mode When driving, it is realized by the aforementioned method o...
