Embodiment Construction

[0024] The technical solution provided by the present invention is: control the output of the image processing module, so that the position of the image displayed on the liquid crystal display screen moves slowly relative to the liquid crystal display screen, avoiding applying the same voltage value to the liquid crystal molecules for a long time, avoiding the occurrence of "Screen burn-in" (image retention) phenomenon.

[0025] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0026] In the embodiment of the present invention, the display screen of a liquid crystal television is taken as an example for illustration, and other liquid ...

Abstract

The invention is applicable to the technical field of liquid crystal display, providing a method for avoiding image retention of liquid crystal display. The method comprises the following steps: regulating the display position of the image on the display screen of the liquid crystal display to ensure that the image display position on the display screen of the liquid crystal display can be moved slowly opposite to the display screen of the liquid crystal display. In the technical scheme provided by the invention, the slow movement of the image position can be realized by only utilizing the output of the program controlling image processing module, thus avoiding the phenomenon of screen burning caused by long-time standstill of image or being less than full-screen display; and the method is only to ensure that the image can change slowly unperceived by users, thus not influencing visual experience of users.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a method for avoiding image residue of a liquid crystal display. Background technique [0002] With the increase in the number of domestic and foreign LCD TVs and LCD monitors and the deepening of their use, the phenomenon of LCD "burn-in" (image retention) has begun to surface. The so-called burn-in refers to the unrecoverable afterimage left on the screen after the LCD screen displays the same picture for a long time. This can be divided into the following situations: sometimes it is the entire still picture, such as test card signals, etc.; sometimes it is part of the still content in the picture, such as the logo, table, LOGO, score, etc. Especially for 16:9 LCD TV sets, when users watch them in 4:3 mode (current TV programs are mainly in 4:3 mode), edge lines will be formed at the junction of black areas without images and bright moving images. T...
