Abstract
The invention relates to a display panel and a display device. The display panel comprises an array substrate; the light-emitting element layer is located on the array substrate, the light-emitting element layer comprises a plurality of light-emitting areas and non-light-emitting areas, the light-emitting areas are arranged in an array, and the non-light-emitting areas are located between the adjacent light-emitting areas; the packaging layer is located on the side, away from the array substrate, of the light-emitting element layer; the light control layer is located on the side, away from the array substrate, of the packaging layer, the light control layer comprises a shading part corresponding to the non-light-emitting area, a first organic layer and a second organic layer located on the first organic layer, and the refractive index of the first organic layer is smaller than that of the second organic layer; the first organic layer comprises a supporting part and a conical part corresponding to the shading part, and the side wall of the conical part is gradually shrunk in the direction away from the packaging layer. According to the display panel, the light emitting efficiency can be ensured while the light emitting angle is limited, and the display power consumption is reduced.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] As a mainstream display panel, organic light-emitting diode (Organic Light Emitting Diode, OLED) display panels are gradually expanding into automotive displays and other application fields. For the sake of driving safety, especially at night or in bad weather, an optical film is usually attached to the vehicle display to limit its light-emitting angle in a certain direction, similar to a privacy film, to prevent light from a large viewing angle from passing through the front shield The windshield reflects the image, which affects the driver's line of sight and creates a driving risk. However, after attaching the optical film, the light will be lost, and the overall brightness of the screen will be greatly reduced. In order to meet the brightness requirements, it is necessary to increase the dis...
