Organic light-emitting display and method for prolonging service life of half-life period of organic light-emitting display

Abstract

An organic light-emitting display (1) and a method for prolonging a half-life of the organic light-emitting display (1). The organic light-emitting display (1) comprises an organic light-emitting display panel (70), used for displaying a frame; a startup detection unit (10), used for sending a startup detection signal to detect startup of the organic light-emitting display (1); a test frame generation unit (20), used for generating a test frame signal, wherein the startup detection signal controls a selection unit (60) to selectively allow the test frame signal to pass through; a time sequence control unit (30), used for driving the organic light-emitting display panel (70) according to the test frame signal; a current increasing unit (40), used for increasing a real-time current to a preset current and registering the increased real-time current when the current increasing unit (40) detects that the real-time current provided by a power supply circuit (50) for the organic light-emitting display panel (70) is lower than the preset current when the test frame is displayed; and a normal frame signal input end (100), wherein a normal frame signal input by the normal frame signal input end (100) controls the selection unit (60) to selectively allow the normal frame signal to pass through, and the organic light-emitting display panel (70) receives the increased real-time current and displays a normal frame when being driven by the time sequence control unit (30) according to the normal frame signal.

Description

technical field [0001] The invention relates to the field of organic light-emitting displays, in particular to an organic light-emitting display and a method for prolonging its half-life. Background technique [0002] Organic Light Emitting Display (OLED) is a display technology that has developed rapidly in recent years. Compared with traditional LCDs, OLED displays have the advantages of self-illumination, wide viewing angle, fast response time, high luminous efficiency, low operating voltage, thin panel thickness, wide operating temperature range, flexible manufacturing and low production cost, so they are regarded as As the mainstream display technology of the next generation, the disadvantage is that OLED has a short lifespan. [0003] The brightness of an OLED display will gradually decay over a long period of use. The T50 lifespan, or half-life, refers to the time it takes for the brightness of an OLED display to decay to half of its original brightness. The longer t...
