Abstract

The invention provides an organic electrogenerated luminescent device and a display, the organic electrogenerated luminescent device comprises a glass base board, an anode layer, an organic luminescent layer, a cathode layer and a sealing cover plate, the organic electrogenerated luminescent device further comprises a radiating layer component, the radiating layer component is arranged between the glass base board and the sealing cover plate and is used for dissipating heat generated by the organic electrogenerated luminescent device. According to the addition of the radiating layer component, heat generated by operation of the organic electrogenerated luminescent device can be dissipated from the organic electrogenerated luminescent device and the display, the temperature during operation of the organic electrogenerated luminescent device is lowered, and the purpose of prolonging the service life of the organic electrogenerated luminescent device is achieved.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence display, in particular to an organic electroluminescence device and a display. Background technique [0002] In recent years, organic light-emitting devices (Organic Light-Emitting Device, OLED) have been used in full-color LEDs due to their excellent properties such as soft light emission, close to natural light, wide viewing angle, fast response speed, light and thin, high brightness, high efficiency and active light emission. Display, backlight and lighting have become research hotspots. [0003] However, compared with ordinary lighting and display products, the service life of organic electroluminescent devices in the prior art is still relatively short. It has been found that the heat generated by organic electroluminescent devices during long-time lighting work is the cause of the device The main reason for the rapid decay of life. Contents of the invention [0004] T...
