Embodiment Construction

[0025] figure 1 This device for preventing display equipment from forming afterimages is described, including an input interface 10, a processing unit connected to the input interface 10, an output interface 30 connected to the processing unit, the above-mentioned processing unit includes a processing module 20, and is connected to the processing module 20. The memory 21, the random number generator 22 connected with the processing module 20, the specific implementation process of the present application is introduced below:

[0026] First, the front-end device generates a signal representing the picture. The format of the digital picture signal can be various, for example: 3 groups of 6-bit, 8-bit or 10-bit data to represent the R / G / B (red) of each pixel on the picture / green / blue) brightness; in addition to pixel data, there are control signals, including line synchronization, field synchronization and data enable signals, which are input into the processing module 20 throug...

Abstract

The invention relates to a device and a method for preventing display equipment from forming incomplete images. In the device, an input signal of a display screen is accessed to the device; and the device performs amendment on the content of a picture pointedly by analyzing the characteristic of the picture. A detailed method of the amendment comprises the steps of: for a part remaining still fora long time, selecting a few points at random, and amending the picture into a black picture for a short time; and outputting data of the amended picture to the display screen to achieve the aims of preventing the display equipment from forming the incomplete images and influencing the picture effect as little as possible. The device and the method can effectively solve the problem of the incomplete images of the display equipment and improve the picture quality.

Description

technical field [0001] The present invention relates to screen display control technology, in particular to a device and method for preventing display equipment from forming afterimages. Background technique [0002] With the continuous development of display technology, various display devices emerge in an endless stream, and the application of using various display devices to publish advertisements and public information is becoming more and more extensive. However, in such applications, the displayed picture often does not change for several hours. If the use time is too long, common display devices such as CRT monitors, LCD screens, plasma screens, etc. will have afterimages. The following is based on the principles of various common display devices to explain the causes of afterimages: [0003] CRT display screen: CRT display screen uses an electron gun to emit high-speed electrons, controls the deflection angle of high-speed electrons through vertical and horizontal d...
