Abstract

The invention discloses a top-emission organic light emitting diode (OLED) structure. The top-emission OLED structure comprises an OLED, a plurality of blocking layers and buffer layers, wherein the buffer layers are arranged between each two adjacent blocking layers, each blocking layer has the capability of moisture oxygen blocking, and at least one buffer layer has the capability of scattering light beam. The invention also discloses a fabrication method of the top-emission OLED structure. Since the buffer layers have the capability of scattering light beam, more light can be irradiated to air, and thus, the luminous efficiency of a device is improved.

Description

technical field [0001] The invention belongs to the technical field of organic light-emitting displays, and in particular relates to a top-emitting OLED structure and a manufacturing method thereof. Background technique [0002] In the current field of lighting and display technology, organic light-emitting diodes (OLEDs) have been widely studied due to their characteristics such as low starting voltage, thinness, and self-illumination, so as to meet the needs of low energy consumption, thinness, and surface light source. [0003] The luminescence of OLED is mainly through the recombination of excitons, and then exits from the light-emitting layer into the air. However, when the light generated by the light-emitting layer is emitted to the air, a large amount of light is lost, so that the light-emitting efficiency of the OLED is not good. Therefore, how to improve the luminous efficiency of OLED is a technical problem that needs to be solved urgently. Contents of the inve...
