Embodiment

[0040] The anti-burn monitoring display according to the embodiment of the present invention has a rectangular array of pixels for displaying a monitoring picture, and the rectangular array of pixels includes a plurality of pixel units, such as figure 1 As shown, the monitoring display also includes:

[0041] An acquisition unit, configured to respectively acquire first RGB values ​​representing the normal brightness of corresponding pixel units in the normal brightness monitoring screen, and send the first RGB values ​​corresponding to each pixel unit to the calculation unit and the control unit respectively;

[0042] Among them, the normal brightness monitoring picture is the monitoring picture collected by the monitoring camera, and the monitoring camera transmits the video signal corresponding to the monitoring picture to the monitoring display in VGA format, DVI format, HDMI format and other formats, and the acquisition unit inside the monitoring display is from the input ...

Abstract

The invention relates to the technical field of display. In order to solve the problem that a display panel of an existing monitoring display is prone to burn, the invention provides an anti-burn monitoring display and a display method thereof. The anti-burn monitoring display comprises an obtaining unit which is used for obtaining a first RGB value representing the normal brightness of a corresponding pixel unit in a normal brightness monitoring image; a calculation unit used for calculating a second RGB value representing the inverse brightness of the normal brightness of the corresponding pixel unit in the monitoring image according to the first RGB value; a control unit, used for obtaining a normal brightness monitoring picture and an inverse brightness monitoring picture according tothe first RGB value and the second RGB value corresponding to each pixel unit. The internal working condition of the display panel of the monitoring display is balanced by displaying the normal brightness monitoring image and the reverse brightness monitoring image in turn. The problem of burn of the monitor is effectively solved, and the method is suitable for the liquid crystal monitoring display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display and a display method thereof. Background technique [0002] Security and monitoring monitors are generally arranged in command halls, monitoring rooms, etc., and are used to display real-time monitoring video images collected by front-end monitoring cameras. Because of security concerns, the requirements for monitoring monitors are higher than ordinary monitors. On the one hand, the monitor is required to work 24 hours a day in terms of usage time, and shutting it down will bring loopholes to the entire security monitoring system and cause immeasurable losses. On the other hand, compared with TV screens and computer monitor screens, the monitoring screen has some significant differences. Most of the monitoring screens come from surveillance cameras, and the main content of the screen is basically static; Generally, fixed characters are superimposed on the area...
