Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no interveni...

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 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...
