Abstract

The invention discloses maintenance device and device of a display screen, relating to an information-processing technology and aiming to solve the problems that long-time display of a static image can leave a residual image on the display screen and even causes a permanent screen burn on the display screen. The invention adopts the technical scheme: timing a static image displayed on the displayscreen; and stopping displaying the static image when the time reaches a preset time. The maintenance device and device can be applied to display devices capable of generating residential images, suchas a plasma display, a cathode-ray tube, and the like.

Description

technical field [0001] The invention relates to information processing technology, in particular to a method and device for maintaining a display screen. Background technique [0002] The display screen of the plasma display uses a plasma tube as a luminous body. Glass electrodes are arranged at both ends of the plasma tube. One of the glass electrodes is coated with three primary color phosphors. The inside of the plasma tube is filled with inert gas. When the voltage is high, the inert gas inside the plasma tube generates plasma, and the plasma excites the glass electrodes coated with three primary color phosphors to emit visible light, thereby realizing imaging. [0003] At present, when a plasma display displays static information (such as still pictures or text) for a long time, the luminous efficiency of the high-brightness area will gradually decline, resulting in residual images on the display screen, and even permanent burns on the screen.
