Embodiment Construction

[0032] 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.

[0033] 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. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The present invention relates to a display screen, a display device and a manufacturing method of the display screen. The effective display area includes an edge display area and a main display area; the edge display area includes a first sub-edge area and a second sub-edge area; the display screen includes: The pixel definition layer has a plurality of openings; the pixel units arranged repeatedly, each pixel unit includes a plurality of sub-pixels, and the light-emitting structure of the sub-pixels is arranged in the openings of the pixel definition layer; the cathode is formed on the pixel definition layer and is located in the pixel definition layer. The cathode of a sub-edge area is provided with openings, the projection of the openings on the array substrate of the display screen is the first projection, and the projection of each opening of the pixel defining layer located in the first sub-edge area on the array substrate is In the second projection, the first projection covers a plurality of second projections. There is a light-emitting structure in the opening, but the place corresponding to the light-emitting structure lacks a cathode, so although the light-emitting structure exists, it does not emit light, thus improving the jaggedness of the edge of the display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen, a display device and a manufacturing method of the display screen. 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 display is generally made of organic materials using evaporation film-forming technology through a metal mask to form organic light-emitting components on the corresponding pixel positions on the deposition subs...
