Embodiment 1

[0029] see figure 1 , this embodiment provides a display panel, figure 1 Shown is a schematic top view of the display panel provided in this embodiment. The surface of the display panel defines a functional area 1 and a display area 2. The diameter of the functional area 1 ranges from 1 to 5 mm. A camera module is arranged below the functional area. .

[0030] see figure 2 , image 3 with Figure 4 , the functional area 1 is provided with an array of pixels 100 , including the pixel area 10 and the light-transmitting area 20 . The pixel region 10 includes a substrate layer 11, a thin film transistor layer 12 and an encapsulation layer 13 arranged in sequence; the thin film transistor layer 12 includes a buffer layer 121, a gate insulating layer 122, a gate layer 123, and a source-drain layer 124 arranged in sequence. and the pixel electrode layer 125.

[0031] The light-transmitting region 20 includes a base substrate layer 21, an organic layer 22, a metal layer 200 and...

Embodiment 2

[0038] This embodiment provides a display device, which includes a main body, on which the display panel according to the present invention is arranged, wherein a driving part is arranged on the main body, and the driving part can control the up and down movement of the camera to drive the light-transmitting Zone 20 transitions between a contracted state and a stretched state.

[0039] When the under-screen camera does not need to take pictures, the driver controls the camera to move downward, the light-transmitting area 20 shrinks, and the pixels 100 approach each other. The area of ​​the pixel area 10 in the functional area 1 becomes larger, and the area of ​​the light-transmitting area 20 becomes smaller. The pixel density in area 1 becomes larger, and the combination of functional area 1 and display area 2 realizes the complete display on the surface of the display panel. Due to the increase in PPI, the display quality of the functional area of ​​the display panel is improv...

Abstract

The present invention provides a display panel and a display device. A display area and a functional area are defined on the surface of the display panel. A pixel array is arranged on the functional area, which includes a pixel area and a light-transmitting area. The light-transmitting area includes sequentially arranged The base substrate layer, organic layer, metal layer and encapsulation layer, the materials used for all the film layers in the light-transmitting area are flexible materials, and the light-transmitting area is scalable; wherein, when the light-transmitting area is in In the contracted state, each of the pixels is close to each other, and the light-transmitting area becomes smaller. At the same time, the functional area can be combined with the display area to realize a complete display on the surface of the display panel. When the light-transmitting area When in the stretched state, each of the pixels is far away from each other, the light-transmitting area becomes larger, and the imaging effect of the camera under the screen is enhanced.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel and a display device. Background technique [0002] With the upgrading of smart phones, the market share of high-screen-to-body phones is getting higher and higher. In order to increase the screen-to-body ratio, mobile phone manufacturers will try their best to design sensors under the screen. At present, the under-screen fingerprint recognition technology has been commercialized, and the screen sound and under-screen iris recognition technologies are becoming more and more mature, which has further improved the screen-to-body ratio. However, the front-facing camera has high requirements on imaging quality, while the imaging quality of the under-screen camera is not good, which makes the realization of the under-screen camera more difficult. [0003] In order to realize the under-screen camera, there are many design methods in the prior art, one of...
