Embodiment Construction

[0033] First, please refer to figure 2 , is a schematic diagram of a liquid crystal panel with improved screen flickering and image sticking in the present invention, wherein the liquid crystal display device 1 in this embodiment includes a liquid crystal panel 2 with n pixels and a control panel that can control the display content of the liquid crystal panel 2 Video controller (not shown in picture). The video controller of the liquid crystal display device 1 uses p=n−m, p=n+m, p=n (where n>>m) pixels to display a normal picture. At the same time, the video controller is used to make the normal picture reciprocate between p and n pixels, for example, moving 1 pixel every 5 minutes so that the human eyes cannot perceive the change.

[0034] Illustrate with an embodiment, when the liquid crystal panel 2 in a liquid crystal display device 1 has 3,000,000 (n) pixels (pixels), and the video controller of the present invention uses p pixels (being p =n-m) 2,900,000 pixels displ...

Abstract

The invention provides a liquid crystal display device and a liquid crystal display method capable of improving picture twinkle and picture ghost. The liquid crystal display device comprises a liquid crystal panel provided with n pixels, and a video controller used for controlling a liquid crystal panel to display a content, wherein the video controller is used for displaying a normal picture through the pixels of p=n-m, p=n+m, and p=n (n is more than m), and the normal picture is reciprocated among p, n*p, and n pixels through the video controller.

Description

[0001] The present invention is a divisional application of No. 2008100804568 patent. technical field [0002] The present invention relates to a liquid crystal display device and method, in particular to a liquid crystal display device and method capable of improving picture flicker and picture sticking. Background technique [0003] In the known liquid crystal display devices, image sticking generally exists, and the sticking phenomenon is caused by the residual charge in the liquid crystal capacitor of each pixel that has not been released. In particular, when the liquid crystal display is turned off, there will usually be residual charge in the liquid crystal capacitor, which will result in the generation of afterimages after the power off. At the same time, if these charges cannot be completely discharged before the next activation of the liquid crystal display, it will cause the liquid crystal display panel to flicker for a short time after the display is turned on aga...
