Abstract

The invention discloses a method for prolonging the life of an organic electroluminescent display, comprising: dividing the display screen into a plurality of sub-regions; calculating the life-influencing factor of each of the sub-regions; according to the image characteristics and The lifetime impact factor is used to calculate the brightness proportional coefficient of each sub-region; to calculate the actual display brightness of the display screen according to the brightness proportional coefficient; to output an image according to the actual display brightness. The invention also provides a display device. Considering factors affecting life span and image features, the brightness scale coefficient is calculated and brightness processing is performed, which reduces the damage to the overall image quality. Select the position to increase or decrease the processing power, adjust the brightness of the image under the premise of ensuring the impact on the image quality, delay the decline of the OLED, and prolong the life of the OLED.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for prolonging the service life of an organic electroluminescent display and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) has the advantages of high contrast ratio, low power consumption, short response time, wide viewing angle and flexibility, etc., which has attracted a lot of attention. However, there are serious problems of brightness degradation and lifespan decay in OLED displays. The decay speed of OLED is positively correlated with the display brightness, that is, the decay is fast when the brightness is high, and the decay is slow when the brightness is low. The main method to delay the decline of OLED is to reduce the display brightness of the high gray level area in the image. [0003] In the prior art, one way to delay the decline of OLED is to set a maximum brightness value, and display the gray levels higher than the...
