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 and a manufacturing method thereof and a display device. The display panel is divided into a display region and a non-display region surrounding the display region. The display region comprises an edge region and a non-edge region. The edge region of the display region is connected with the non-display region and surrounds the non-edge region. The display panel comprises a light extraction layer. The light extraction layer has a thickness at the edge region of the display region greater than the thickness at the non-edge region of the display region so that the light extraction efficiency in the edge region of the display region is enabled to be higher, the light extraction efficiency in the non-edge region of the display region is lower, then the light emergent from the edge region of the display region is enhanced by increasing the thickness of the light extraction layer in the edge region of the display region, the brightness of the edge region is increased, the brightness difference between the non-edge region and the edge region is reduced, the brightness of the edge region of the display panel and the brightness of the non-edge region tend to be the same, the display uniformity of the display panel is improved and the display effect is improved.

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...
