Abstract

The invention discloses an organic light-emitting device, a method for adjusting brightness thereof, and a display device. The organic light-emitting device includes: an organic light-emitting diode substrate, on which an organic light-emitting element is arranged; a package structure, forming a sealed space between the package structure and the organic light-emitting diode substrate; and an external compensation unit, the The external compensation unit includes a photosensitive sensor and a compensation adjustment component, wherein the photosensitive sensor is configured to be able to detect the luminous intensity of the organic light-emitting element, and the compensation adjustment component is disposed on the light output side of the packaging structure and faces the on the side wall of the sealed space, and is configured to be able to adjust the luminous intensity of the organic light emitting device according to the detection signal of the photosensitive sensor. Therefore, the organic light-emitting device can obtain accurate external compensation, and can perform real-time compensation.

Description

technical field [0001] The invention relates to the field of organic optoelectronics, in particular to an organic light-emitting device, a method for adjusting brightness thereof, and a display device. Background technique [0002] Organic light-emitting display (OLED) is a thin-film light-emitting device made of organic light-emitting materials and driven by DC voltage. The organic light-emitting display technology is different from the traditional LCD display method. It does not need a backlight and uses current to drive the organic light-emitting material coating. glow. Moreover, compared with traditional LCD displays, organic light-emitting displays can be made lighter and thinner, have a larger viewing angle, and can significantly save power. However, in current organic light-emitting displays, the TFTs used to control pixels all have problems with uniformity or stability, which causes differences in brightness of the devices and affects the display. For the above-men...
