Abstract

The present application discloses an OLED panel and an OLED display. The OLED panel includes: an OLED device; a thin-film encapsulation structure formed on the OLED device, including a first inorganic film layer, a first organic film layer, a second inorganic film layer, Film layer, the 3rd inorganic film layer and the 4th inorganic film layer, wherein, the refractive index of the first inorganic film layer is greater than the refractive index of the first organic film layer, the refractive index of the second inorganic film layer and the 4th inorganic film layer The refractive indices are all smaller than the refractive index of the third inorganic film layer. Through the OLED panel, the light extraction efficiency of the OLED panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED panel and an OLED display. Background technique [0002] Organic Light Emitting Diode (OLED) display is a promising flat panel display technology, which has self-illumination, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption and flexible display. and other characteristics. Currently, OLED displays are favored by major display manufacturers, and have become the third generation of displays after CRT (Cathode Ray Tube) displays and Liquid Crystal Displays (Liquid Crystal Display, LCD). [0003] Since the film layers such as organic light-emitting materials used in OLED panels are very sensitive to water and oxygen, the requirements for water and oxygen are extremely strict. Generally speaking, flexible film layers will be packaged on organic light-emitting materials. The commonly used packaging structure is an inorganic or ...
