Abstract

The invention discloses a screen maintenance method used for a plasma display and a device thereof, relating to a method used for screen maintenance and a device thereof. In order to solve the problem that the plasma display in the prior art remains residual shadows on the screen after static images are watched for a long time, the screen maintenance method used for the plasma display comprises the steps as follows: more than one maintenance pictures are memorized; the maintenance pictures are called; the maintenance pictures are displayed on the screen of the plasma display. The method and the device can be applied to the plasma display and has a maintenance effect on the screen of the display.

Description

technical field [0001] The invention relates to a screen maintenance method and device, in particular to a plasma display screen maintenance method and device. 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 discharge in the plasma tube will be triggered 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 different components of three primary colors. Each plasma tube is what we call a pixel of a plasma display, and the picture we...
