Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] As mentioned in the background art, with the continuous improvement of the resolution of the existing display panel, the number of pixel units is also increasing, so that the interval between the pixel units is gradually reduced. In addition, as the luminous efficiency of light-emitting materials used in OLED displays improves, high luminance can be achieved with low current and low voltage, thereby reducing power consumption. Therefore, a small amount ...

Abstract

The invention discloses a display panel, electronic equipment and a manufacturing method. The display panel comprises a substrate, a positive electrode layer and a negative electrode layer arranged on the same side of the substrate, and a light emitting function layer arranged between the positive electrode layer and the negative electrode layer, wherein the positive electrode layer and the negative electrode layer are arranged in opposite in a direction perpendicular to the substrate; the positive electrode layer is arranged between the substrate and the negative electrode layer, and the positive electrode layer is divided into multiple positive electrodes; the light emitting functional layer comprises at least a sub function layer; the light emitting functional layer is divided into multiple pixel units in array arrangement; the pixel units are in one-to-one correspondence with the positive electrodes in the direction perpendicular to the substrate; a cut-off structure is arranged between at least two adjacent pixel units in a first direction; the cut-off structure enables the at least one sub functional layer to be cut off between the two pixel units; and the first direction is parallel to the substrate. According to the display panel, the phenomenon of light emission caused by leakage current is avoided, and the image display effect is ensured.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a display panel, a manufacturing method and electronic equipment. Background technique [0002] In recent years, flat panel displays such as LCD displays and OLED displays have gradually replaced CRT displays and become mainstream products in the display market. Among them, OLED displays have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle range, wide operating temperature range, flexible display and large-area full-color display. It is considered by the industry to be the display with the best development potential. [0003] The main structure of the OLED display device is an OLED device, and the OLED device includes an anode and a cathode arranged oppositely; and a functional layer arranged between the anode and the cathode. The light-emitti...
