Embodiment 1

[0027] see figure 1 , figure 2 , image 3 , the embodiment of the present application provides a display panel 200. The display panel 200 includes a substrate 11, an array composite layer disposed on the substrate 11, and an array of light-emitting devices 59 disposed on the array composite layer. The display panel 200 includes at least one transparent In the light area 201 , the light-transmitting area 201 is provided with a color compensation layer 191 , and the ambient light presents white light after passing through the light-transmitting area 201 .

[0028] Specifically, such as figure 1 As shown, the display panel 200 includes a light-transmitting area 201 . The light-transmitting area 201 is an area corresponding to a light sensor, such as an under-display camera area. The normal display area 202 at least partially surrounds the light-transmitting area 201 . The color compensation layer 191 is disposed at least in the light-transmitting region 201 of the display pan...

Embodiment 2

[0043] see figure 1 , Figure 4 The same or similarities between this embodiment and Embodiment 1 will not be described in detail. The difference is that the pixel definition layer 20 uses the material of the color compensation layer 191, that is, the pixel definition layer 20 is used as a color compensation layer. Compared with Embodiment 1 , can reduce the production process and reduce the film thickness.

[0044] The display panel 200 includes a substrate 11, an array composite layer disposed on the substrate 11, and an array of light-emitting devices 59 arranged on the array composite layer. The display panel 200 includes at least one light-transmitting region 201, and the light-transmitting region 201 is provided with a color compensation layer 191 , the ambient light presents white light after passing through the light-transmitting region 201 .

[0045] Specifically, the array composite layer includes a buffer layer 12 disposed on the substrate 11 , a transistor functi...

Embodiment 3

[0051] see figure 1 , Figure 5 The same or similarities between this embodiment and the first embodiment will not be repeated. The difference is that the flat layer 18 uses the material of the color compensation layer 191 , that is, the flat layer 18 is used as a color compensation layer.

[0052] The display panel 200 includes a substrate 11, an array composite layer disposed on the substrate 11, and an array of light-emitting devices 59 arranged on the array composite layer. The display panel 200 includes at least one light-transmitting region 201, and the light-transmitting region 201 is provided with a color compensation layer 191 , the ambient light presents white light after passing through the light-transmitting region 201 .

[0053] Specifically, the array composite layer includes a buffer layer 12 disposed on the substrate 11, a transistor functional layer 100 disposed on the buffer layer 12, a flat layer 18 disposed on the transistor functional layer 100, and a pix...

Abstract

The embodiment of the invention discloses a display panel and a display device.The display panel comprises a substrate, an array composite layer arranged on the substrate and light-emitting devices arranged on the array composite layer in an array mode, the display panel comprises at least one light-transmitting area, the light-transmitting area is provided with a color compensation layer, and the ambient light is white light after passing through the light-transmitting area, so that the working performance of optical sensors such as a camera can be improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting display panels (OLED panels) have been widely used in people's lives, such as display screens of mobile phones and computers. With the development of display technology and people's advanced requirements for display technology, high screen-to-body ratio, full-screen displays and their application terminals have gradually developed, and under-screen fingerprint and under-screen camera technologies have been proposed or developed, that is, the display of application terminals The back of the panel is provided with optical sensors such as a fingerprint identification module and a camera, and the area of ​​the display panel where the camera is installed can not only display images, but also take pictures through external ambient light. [0003] However, in the flexible OLED panel, the flexible su...
