Patent ID: 10403819

Abstract:
A pixel define layer and manufacturing method thereof and the related light emitting display are disclosed. The pixel define layer is arranged on a conductive layer of a substrate and comprises a base film layer. The base film layer has a plurality of openings each of which corresponds to a light-emitting region of a sub-pixel unit. A spacing base body is formed between the adjacent openings. An upper surface of each spacing base body is coated with a hydrophobic quantum dot material and a side wall of each opening is coated with a hydrophilic quantum dot material. With the pixel define layer and manufacturing method thereof and the related light emitting display according to embodiments of the disclosure, the ink within the sub-pixel would not ooze to the outside of the sub-pixel to result in color mixture between the adjacent sub-pixels, and the light emitting region within the pixel would not be decreased. By selecting suitable quantum dot materials, the photochromic efficiency can be improved. The process is simple and suitable for large size.
