Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] As mentioned in the background technology, existing organic light-emitting display panels have the problem of poor brightness uniformity, which affects the display effect. According to the research of the inventors, the reason for the above problems is that the existing organic light-emitting display panels usually include multiple A light-emitting device and a variety of signal lines used to transmit electrical signals. Organic light-emitting devices usually include a cathode layer on the entire surface. Th...

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, wherein the display panel is divided into a display area and a non-display area surrounding the display area, the display area includes an edge area and a non-edge area, and the edge area of ​​the display area and the non-display area The regions are connected and surround the non-edge area; the display panel includes a light extraction layer, and the thickness of the light extraction layer in the edge area of ​​the display area is greater than that in the non-edge area of ​​the display area, which can make the light extraction efficiency in the edge area of ​​the display area higher. In the non-edge area of ​​the display area, the light extraction efficiency is relatively low, and the light output in the edge area of ​​the display area is enhanced by increasing the thickness of the light extraction layer in the edge area of ​​the display area, so that the brightness of the edge area increases, and then the non-edge area is reduced. The brightness difference between the edge area and the edge area makes the brightness of the edge area of ​​the display panel tend to be consistent with the brightness of the non-edge area, which improves the display uniformity of the display panel, thereby improving the display effect.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, organic light-emitting display panels are more and more widely used due to their advantages such as self-illumination, wide color gamut, and wide viewing angle. [0003] The problem of poor brightness uniformity exists in the existing organic light-emitting display panel, which affects the display effect. Contents of the invention [0004] The invention provides a display panel, a manufacturing method thereof, and a display device, so as to improve the display uniformity of the display panel and the display device. [0005] In the first aspect, the embodiment of the present invention provides a display panel. The display panel is divided into a display area and a non-display area surrounding the display a...
