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

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic light emitting diode element. 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 Luminance unevenness of outgoing light. Contents of the invention [0003] The main technical problem to be solved by the ...
