Title:
PIXEL STRUCTURE AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/035894
Kind Code:
A1
Abstract:
A pixel structure and manufacturing method. The pixel structure comprises: a substrate (11); an anode electrode layer (12) provided on the substrate (11); a plurality of pixel units (15) provided on the anode electrode layer (12) and arranged in a rectangular array, wherein each of the pixel units (15) comprises four sub-pixel units (151, 152, 153, 154) arranged in a rectangular array, and the emitting colours of two sub-pixel units (151, 152, 153, 154) facing each other on the adjacent side of any two adjacent pixel units (15) are the same; and a cathode electrode layer (18) provided on the plurality of pixel units (15). Therefore, when a metal photomask is used to form the plurality of pixel units (15), a mask opening can be shared by one sub-pixel unit (151, 152, 153, 154) of at least four pixel units (15), so as to improve the process capability of the metal photomask and the resolution of a display screen.
