OLED (optical light emitting diode) pixel arrangement structure and display device

Abstract

The invention discloses an OLED (optical light emitting diode) pixel arrangement structure and a display device. The pixel arrangement structure comprises a plurality of repeated arrangement virtual octagons, wherein each virtual octagon consists of four first sub pixels, four second sub pixels and at least two third pixels, the centers of the at least two third sub pixels are coincident with the center of the virtual octagon, the centers of the four first sub pixels of each virtual octagon are respectively positioned at four first peaks of the left upper corner and the right lower corner of the virtual octagon, the centers of the four second sub pixels of each virtual octagon are respectively positioned on four second peaks of the right upper corner and the left lower corner of the virtual octagon, and a basic pixel unit is formed through the adjacent first sub pixels and the second sub pixels in each virtual octagon and the third sub pixels opposite to the first sub pixels and the second sub pixels. The OLED pixel arrangement structure and the display device have the advantages that the limitation of a manufacturing process and a film plating process is broken through, an OLED display PPI (pixels per inch) value and the resolution ratio can be effectively improved, and the OLED display image quality and the OLED display image effect are improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to an OLED pixel arrangement structure and a display device. Background technique [0002] In recent years, organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, and use temperature range Wide, simple structure and manufacturing process and other excellent characteristics, it is considered to be the new application technology of the next generation flat panel display. Organic light-emitting display technology consists of very thin coatings of organic materials and glass substrates that emit light when an electric charge passes through them. Compared with LCD displays, OLED has the advantages of saving power, being thinner, and having a wider viewing angle, which is unmatched by LCD. OLED is divided ...

Problems solved by technology

[0004] The main factor affecting the high PPI value is the high fineness of the mask plate. Since the mask plate (Mask) opening area has a lower limit of specification, and in order to avoid the influence of the tolerance (tolerance) in the manufacturing process, the openings of adjacent pixels need to be pre-set. Leaving a gap (gap) results in a small pixel density, resulting in the inability to greatly improve the PPI
