Abstract

The invention discloses an organic light-emitting device, and the organic light-emitting device comprises a substrate, an organic light-emitting layer, a phase change protection layer and a packaginglayer; the organic light-emitting layer is arranged on the substrate, and the packaging layer is arranged on the organic light-emitting layer, wherein the phase change protection layer can be arrangedin the organic light-emitting layer or between the packaging layer and the organic light-emitting layer; the material of the phase change protection layer has the characteristics of absorbing and releasing heat in the solid-solid phase change process; when the external environment temperature changes drastically, the organic light-emitting device can still keep a relatively stable working temperature, and the impact resistance and brightness stability of the organic light-emitting device to the environment temperature change are improved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to setting a phase-change protective layer in an organic light-emitting device to improve the impact resistance and brightness stability of the organic light-emitting device to environmental temperature changes. Background technique [0002] Organic light-emitting device (OLED) displays have the characteristics of wide material selection range, low driving voltage, total active light emission, light weight, wide operating temperature range and can be fabricated on soft substrates, etc., which can meet the higher requirements of display technology in today's information age The requirement of performance and greater information capacity has become one of the hottest topics in the scientific and industrial circles. In addition, due to the high efficiency and low cost of OLED, its application prospect in the field of lighting is also promising. [0003] Improving the performance of o...
