Abstract

An OLED encapsulating structure and a manufacturing method thereof, and a light-emitting device are disclosed. The OLED encapsulating structure comprises: a base substrate (4), an OLED (1), barrier layers (2), and optical modulation layers (3); the OLED is formed on the base substrate; the barrier layers and the optical modulation layers are alternately and periodically formed on the OLED. The OLED encapsulating structure can reduce viewing-angle dependence of an OLED caused by a micro-cavity effect.

Description

technical field [0001] The invention relates to the field of manufacturing organic electroluminescent displays, in particular to an OLED encapsulation structure, a manufacturing method thereof, and a light emitting device. Background technique [0002] Organic Light-Emitting Diode (hereinafter referred to as: OLED) is called the first because of its advantages such as active light emission, good temperature characteristics, low power consumption, fast response, bendable, ultra-thin and low cost. Three generations of fantasy display technology. At present, driven by the continuous capital investment and technology research and development of global manufacturers, OLED flat panel display technology is tending to the stage of increasingly mature mass production technology and rapid growth of market demand. [0003] OLED can be divided into three types according to the light output direction, namely: bottom-emitting OLED, top-emitting OLED and double-sided emitting OLED. Botto...
