Embodiment Construction

[0008] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0009] The present invention utilizes the afterimage phenomenon (burning phenomenon) which is accumulated over a long period of time. As long as the opportunity to recover the luminous efficacy is provided intermittently, the luminous efficacy in the high-brightness area can be maintained for a much longer time; The slow position and brightness changes are very insensitive to these two characteristics, combined with the high-speed computing capability of integrated circuits, an effective intelligent method for eliminating afterimages is proposed, such as figure 1 , 2 shown, including the following steps:

[0010] 1) Digitally process the image signal;

[0011] 2) According to the image signal, it is judged whether the image is a still picture;

[0012] 3) Judging whether the continuous display time of the still picture exce...

Abstract

The invention discloses a method to intelligent eliminating ghost. It includes the following steps: digitalizing the image processing signal; judging the image whether static according to the image signal; judging the last display time span whether exceeding the preset value; if the span time exceeding the preset value, supplying light emitting function recovering chance for the imate. Thus, the light emitting function of the high brightness area would maintain longer, and because naked eye is not sensitive to the small and slow change of location and brightness, it doesn't influence the visual effect and can effectively decrease the chance of having ghost. Thus, the using life of the monitor would be prolonged.

Description

【Technical field】: [0001] The invention relates to a method for intelligently eliminating afterimages. 【Background technique】: [0002] All display devices display a still picture for a long time, which will lead to the luminous efficiency of the area that displays high brightness for a long time is gradually lower than the area that displays low brightness for a long time. Over time, when other pictures are displayed, the original still picture remains. The image can be called the phenomenon of afterimage or burn in. Some display devices (such as plasma display PDP, cathode ray CRT projection tube, single crystal silicon reflective panel LCOS) this phenomenon is relatively easy to occur. How to reduce the chance of image sticking and prolong the service life of display devices is a technical problem to be solved urgently. 【Invention content】: [0003] The purpose of the present invention is to solve the above problem of afterimages in still images, and provide an intell...
