A kind of oled lighting device and manufacturing method

Abstract

The invention discloses an OLED (organic light emitting diode) luminescent device and a manufacturing method thereof which are applied to the optoelectronic technical field. The device comprises a transparent electric conduction baseplate and a packaging rear cover, wherein the packaging rear cover is connected with the transparent electric conduction baseplate through a packaging adhesive; a transparent conducting electrode, an organic material functional layer and a metal electrode layer are arranged between joints of the transparent electric conduction baseplate and the packaging rear cover; the transparent conducting electrode and the metal electrode layer are switched on to supply direct current power to the organic material layer so that the organic material layer is driven to emit light, and light sequentially penetrates through a backlight side and a light-outgoing side of the transparent electric conduction baseplate so as to realize lighting; and a high refractive index matching layer is arranged on the light-outgoing side of the transparent electric conduction baseplate. According to the method and the device disclosed by the invention, since the light-outgoing side of the transparent electric conduction baseplate is provided with the high refractive index matching layer, the light output efficiency is obviously improved, and the brightness of the OLED luminescent device is increased.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to an OLED lighting device and a manufacturing method. Background technique [0002] Organic Light Emitting Device (OLED) is widely used in flat panel displays, backlight modules and lighting due to its characteristics of ultra-thin, high brightness, fast response, low power consumption, high efficiency and simple production. To deposit a very thin organic material between two electrodes, a direct current is applied to the organic light-emitting material to make it emit light. [0003] The practical features of OLED lighting devices are high brightness, generally between 100-500cd / m2, and the highest brightness can reach 2,000-3,000cd / m2; long life. An OLED lighting device generally includes a white-emitting organic electroluminescent device and a transparent conductive substrate. [0004] In product applications, it is first necessary to improve the luminous efficiency o...
