Embodiment 1

[0038] figure 2 It is a schematic cross-sectional structure diagram of a display panel provided by Embodiment 1 of the present invention, image 3 It is a schematic structural diagram of the concave-convex interface in the display panel provided by Embodiment 1 of the present invention, Figure 4 Another structural schematic diagram of the concave-convex interface in the display panel provided by Embodiment 1 of the present invention, Figure 5 Another schematic cross-sectional structure diagram of the display panel provided by Embodiment 1 of the present invention.

[0039] The inventor of the present invention found in the actual research process that the current display panel has a problem of high reflectivity of ambient light, and the inventor found that the reason for this problem lies in the fact that in the existing display panel, circular polarizers are used Eliminate the reflection of the cathode surface to the external ambient light, but because the circular polar...

Embodiment 2

[0059] Figure 6 It is a schematic cross-sectional structure diagram of the display panel provided by Embodiment 2 of the present invention.

[0060] The difference between the display panel provided in this embodiment and the above-mentioned embodiments is as follows: Figure 6 As shown, the side of the pixel defining layer 301 facing the black matrix 61 forms a concave-convex interface 50, and the side of the light emitting unit 30 facing the thin film encapsulation layer 40 is an arc-shaped surface, specifically, as Figure 6 As shown, the side of the light-emitting unit 30 facing the thin-film encapsulation layer 40 is a concave arc surface, or the side of the light-emitting unit 30 facing the thin-film encapsulation layer 40 may also be an arc-shaped convex surface, and the thin-film encapsulation layer 40 covers the concave-convex interface 50 and the light-emitting unit 30 Above, that is, in this embodiment, the concave-convex interface 50 is set on the top surface of ...

Embodiment 3

[0066] This embodiment provides a display panel, and the display panel is specifically a flexible OLED panel, wherein the flexible OLED panel includes several light emitting units 30 and a pixel defining layer 301 arranged on the array substrate 10, and a plurality of light emitting units 30 located between the light emitting units 30 The filter layer 60 and the black matrix 61 on the top, that is, the circular polarizer is replaced by the filter layer 60 and the black matrix 61, and the thickness of the filter layer 60 and the black matrix 61 is smaller than that of the circular polarizer, and the filter layer 60 and the black The matrix 61 is often made of organic materials, has a certain degree of flexibility, and can be bent, so that the display panel tends to be ultra-thin and bendable, so that it can be applied to a flexible display screen. At the same time, in this embodiment, it also includes : thin film encapsulation layer 40, and thin film encapsulation layer 40 and / o...

Abstract

The invention provides a display panel, and a display device. The display panel comprises a plurality of light-emitting units and a pixel limiting layer which are arranged on an array substrate, filtering layers and a black matrix located above the light-emitting units, and a film packaging layer, wherein a concave-convex interface is arranged on the film packaging layer or the pixel limiting layer, or concave-convex interfaces are respectively arranged on the film packaging layer and the pixel limiting layer. The display panel provided by the invention has the advantages that the reflectivityof external ambient lights can be reduced, so that good display effects of the display panel are ensured, and the problem of the conventional panel that the display effects of the display panel are greatly affected by a high reflectivity of the external ambient lights is further solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Display screens have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books, and navigation equipment) and large-screen electronic devices. Among them, organic light-emitting diodes (Organic Light-Emitting Diode, referred to as : OLED) has been gradually applied to display screens due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. [0003] At present, in OLED displays, BM-CF technology is used to form a color filter (ColorFilter, referred to as: CF) and a black matrix (Black Matrix, referred to as: BM) on the thin film encapsulation layer to replace the circular polarizer (because the polarizer and Thick and hard), wherein, the black matrix is ​​used as a color-defin...
