ORGANIC ELECTROLUMINESCENT DISPLAY PANEL, MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18446065 titled 'ORGANIC ELECTROLUMINESCENT DISPLAY PANEL, MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE
Simplified Explanation
- The patent application describes an organic electroluminescent display panel and a method of manufacturing it. - The display panel aims to solve the problem of pixel crosstalk caused by lateral conduction of the charge generation layer. - The panel includes a substrate, an anode layer, and a pixel defining layer that defines pixel units. - A recess is created in the pixel defining layer between adjacent pixel units. - The panel also includes a stack of organic electroluminescent units and a charge generation layer between adjacent units. - The charge generation layers of adjacent pixel units are disconnected at the recesses, preventing crosstalk. - A cathode layer is placed over the stack, and it remains continuous at the recess. - The innovation helps alleviate or avoid pixel crosstalk problems in organic electroluminescent display panels.
Original Abstract Submitted
An organic electroluminescent display panel, a method of manufacturing the same, and a display device that can alleviate or avoid the occurrence of pixel crosstalk problems due to lateral conduction of the charge generation layer are disclosed. An organic electroluminescent display panel is provided which comprises: a substrate; an anode layer and a pixel defining layer over the substrate, the pixel defining layer defining pixel units, wherein a recess is provided in the pixel defining layer between adjacent pixel units; a stack of organic electroluminescent units over the anode layer and the pixel defining layer, the stack comprising at least two organic electroluminescent units and a charge generation layer disposed between organic electroluminescent units which are adjacent to each other; a cathode layer over the stack. The corresponding charge generation layers of the adjacent pixel units are disconnected at the recesses. The cathode layer is continuous at the recess.
