Embodiment Construction

[0023] In order to solve the problem in the prior art that when a plasma display is watching an image for a long time, the image at a certain place remains still for a long time, leaving an afterimage on the screen. The present invention provides a method for reducing the afterimage on the screen of a plasma display. The method can effectively dilute or even eliminate residual images on the screen of the plasma display by inverting the color values ​​to be displayed of the pixels on the plasma display and outputting the inverted color values ​​to be displayed.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more comprehensible, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, the method for reducing residual image on the...

Abstract

The invention discloses a method for desalinating screen image retention of a plasma display and a device thereof, relating to a screen maintenance method and a device. When watching pictures for a long time on the plasma displays of the prior art, the image retention remains on the screen in case a picture at one place on the screen stands for a long time; therefore, the invention is invented forsolving the problem. The method provided by the embodiment of the invention comprises the steps of: receiving displayed color values of pixel on the plasma display; taking the displayed color reservevalues of the pixel; outputting the displayed color reserve values of the pixel. The invention is applicable for the plasma display and can desalinate the image retention left on the plasma display screen.

Description

technical field [0001] The invention relates to a method and a device for screen maintenance, in particular to a method and a device for lightening residual images on a plasma display screen. Background technique [0002] The working principle of the plasma display is: install hundreds of thousands of plasma tubes on the display screen as illuminants (pixels), the inside of the plasma tube is filled with inert gases such as helium and neon, and each plasma tube has two glass electrodes. One of the glass electrodes is coated with three primary color phosphors; when a high voltage is applied between the two glass electrodes of the plasma tube, the inert gas in the plasma tube is discharged to generate plasma; the plasma generates ultraviolet rays, And excite the glass electrode coated with three primary color phosphors to emit visible light, which is formed by mixing three primary colors of different components. Each plasma tube is what we call a pixel of a plasma display, an...
