Organic light-emitting display apparatus and pixel structure therefor

Abstract

Disclosed is a pixel structure. The pixel structure comprises multiple pixel units, wherein each pixel unit adopts a rectangular shape, and comprises first sub pixels, second sub pixels and third sub pixels; the first sub pixels and the second sub pixels are L-shaped; the first sub pixels and the second sub pixels are arranged in opposite and form a region used for at least accommodating a part of the third sub pixels; at least one edges of the third sub pixels are at least partially overlapped with one edge of the corresponding pixel unit; the transverse adjacent pixel units are in mirror image distribution; and the longitudinal adjacent pixel units are in mirror image distribution. Due to the structure, the first sub pixels, the second sub pixels and the third sub pixels are adjacent to the corresponding sub pixels of the adjacent pixel units, so that an opening can be shared by the adjacent sub pixels in the manufacturing process, and the opening area in evaporation can be enlarged; meanwhile, a reserved gap is not required in the evaporation process of the adjacent sub pixels, so that the aperture ratio is improved, and the a relatively high physical resolution ratio can be further realized. An organic light-emitting display apparatus adopting the pixel units is relatively high in resolution ratio.

Description

technical field [0001] The present invention relates to the technical field of organic light-emitting display, in particular to a pixel structure and an organic light-emitting display device using the pixel structure. Background technique [0002] Organic light-emitting diode (OLED) is known as the flat panel display and third-generation display technology in the 21st century, and has become a major research hotspot in the world. Organic light-emitting diodes have many characteristics such as low driving voltage, active light emission, wide viewing angle, high efficiency, fast response speed, easy realization of full-color large-area wall-mounted display and flexible display, and also have the advantages of low manufacturing cost and low power consumption. [0003] The light-emitting layer of the OLED screen generally uses organic materials to form organic light-emitting components at the corresponding pixel positions on the deposition substrate through a metal mask using ev...

Problems solved by technology

When the above pixel structure achieves high PPI (PixelPerInch, pixels per inch), that is, physical resolution, the aperture ratio of red pixels and green pixels is too small to meet the requirements of high PPI.
