High temperature resistant micro cavity OLED (organic light emitting siode) screen and production process thereof
The invention provides a high temperature resistant micro cavity OLED (organic light emitting diode) screen and a production process thereof. The screen comprises a substrate as well as an anode, a light emitting layer, a cathode and a packaging cover which are connected on the substrate sequentially; the screen further comprises a metal layer which is clamped between the anode and the substrate and comprises a part extending out of the packaging cover. The OLED screen has the advantages that the metal layer partially extends out of the packaging cover and is exposed to an open environment after packaging, so that timely cooling is facilitated, and the cooling effect of the screen is improved. The metal layer with high reflectivity is further arranged between the anode and the substrate, so that a micro cavity structure is formed between the anode and the cathode, and the efficiency of the screen can be effectively improved by the micro cavity effect of the micro cavity structure. The production process is simple and feasible, high in operability and suitable for large scale production.
