Embodiment Construction

[0027] 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.

[0028] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has many advantages such as full solid state, active light emission, fast response speed, high contrast ratio and flexible display, and has wider development space. The current OLED display panel takes advantage of flexibility and bendability, and a bending structure is formed at the edge of the display panel to form a bending area, which helps to realize the narrow frame and full-screen display effect of the OLED display device....

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a light-emitting unit located on the substrate and a light extraction layer located at one side,far away from the substrate, of the light-emitting unit, wherein the substrate comprises a plane area and bending areas located on at least one side of the plane area; the light-emitting unit comprises sequentially laminated first electrode, light-emitting functional layer and second electrode along the direction, pointing to the light-emitting unit, of the substrate; the thickness of the light-emitting functional layer corresponding to the plane area is different from that corresponding to the bending areas; and the optical thickness of the light extraction layer corresponding to the plane area is different from that corresponding to the bending areas. According to the display panel and the display device, the decay rates of different colors of light along with a viewing angle can be adjusted, the color shift of the viewing angle of each bending area is improved, the color shift degrees of the bending areas and the plane area are reduced, and the display effect of the display panel isimproved. Meanwhile, the same display color of the plane area and the bending areas at a small viewing angle can be ensured and the display effect of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In the display panel, there is a problem of asynchronous observation angles in the flat area and the bending area of ​​the display panel under the field of view, resulting in different degrees of color shift in the display screens in the flat area and the bending area. Contents of the invention [0003] The invention provides a display panel and a display device to improve the color shift in the bending area and reduce the color shift difference between the plane area and the bending area. [0004] In the first aspect, an embodiment of the present invention provides a display panel, which is characterized by comprising a substrate, a light emitting unit located on the substrate, and a light extraction layer located on a side of the light emitting unit away from the substrate; [000...
