Problems solved by technology

However, since the manufacturing process of the luminescent layer is mostly formed by photolithography after solution coating, when the solution is coated, the liquid droplets are easily transferred to the edge, thereby causing the edge thickness of the luminescent layer to be greater than the middle thickness. This uneven thickness will cause Luminance non-uniformity of outgoing light

Abstract

The invention discloses a stable organic light emitting diode. The stable organic light emitting diode comprises a silicon carbide substrate, an aluminum nitride buffering layer, a cathode layer, an organic layer, an anode layer and a glass panel stacked in sequence, the refractive index of the anode layer is larger than that of the glass panel, the organic layer comprises isolation layers distributed on the cathode layer in a matrix mode and light emitting layers, the light emitting layers are arranged among multiple isolation layers, the surfaces of the light emitting layers sink downwards to form a curved surface, the anode layer is provided with multiple penetrating through holes, the positions of the through holes correspond to those of the light emitting layers, and the light emitting layers comprise first phosphorus light material layers, first partition layers, blue light fluorescent material layers, second partition layers and second phosphorus light material layers stacked insequence, wherein the first partition layers can allow electrons to pass through and stop cavities from passing through, and the second partition layers can allow the cavities to pass through and stop the electrons from passing through. The stable organic light emitting diode can avoid the phenomenon that the brightness of emerged light is not uniform.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a stable organic light emitting diode. Background technique [0002] At present, organic light-emitting diodes are generally composed of a cathode layer, a light-emitting layer, an anode layer and a glass layer in sequence. Electrons and holes are injected from the cathode and anode respectively, forming excitons in the light-emitting layer and exciting the material of the light-emitting layer to emit light. However, since the manufacturing process of the luminescent layer is mostly formed by photolithography after solution coating, when the solution is coated, the liquid droplets are easily transferred to the edge, thereby causing the edge thickness of the luminescent layer to be greater than the middle thickness. This uneven thickness will cause The brightness unevenness of the outgoing light. Contents of the invention [0003] The main technical problem to be solved ...
