Pixel structure and organic light-emitting display device using the same

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 positioned on the two sides of the third sub pixels respectively; the second sub pixels have the same shapes as the first sub pixels; the third sub pixels are T-shaped; 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 of 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 physical resolution (commonly represented by PixelPer Inch, that is, PPI), that is, the physical resolution, the blue pixel cannot share the aperture with the blue pixel in the adjacent pixel unit, so that the aperture ratio is too small and Unable to meet high PPI requirements
