Problems solved by technology

Generally, this "afterimage" will gradually disappear after the picture is still for a short time, but if the still picture is played for a long time or accumulated for a long time, it will cause permanent damage to the display, that is, the "afterimage" will not fade away

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The term "user interface" in this application refers to a media interface for interaction and information exchange between an application program or an operating system and a user, and it realizes the conversion between the internal form of information and the form acceptable to the user. A commonly used representation form of a user interface is a graphical user interface (GUI), which refers to a user interface related to computer o...

Abstract

The embodiment of the invention relates to the technical field of display, in particular to a method for starting screen protection of display equipment and the display equipment, and the method comprises the steps: obtaining a plurality of partition images corresponding to a to-be-displayed image on a display, and determining the brightness information of each partition image according to the gray value of each pixel in each partition image; and for each partition image, when it is determined that the duration in which the brightness information of the partition image of the preset proportiondoes not change exceeds the preset duration, controlling a display screen of a display to protect the display screen. In the embodiment of the invention, the burn-in phenomenon caused by the fact that the brightness information of the display interface is not changed for a long time can be avoided by utilizing screen protection, and the service life of the display is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for enabling a screen saver of a display device and the display device. Background technique [0002] OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high response speed. In recent years, major domestic and foreign manufacturers have successively launched high-end TVs with OLED screens. Although OLED has the above-mentioned various advantages, it also has a fatal flaw of "burning screen". [0003] The correct term for "burning screen" should be called "residual". As long as it is a self-luminous display, whether it is a picture tube, plasma or OLED, there will be "afterimage" phenomenon. When the image remains unchanged for a long time and the contrast of the screen is strong, after the screen is switched, some shadows of the original bright part will remain in ...
