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 and 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 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, the functional area is provided with a pixel array, and the functional area comprises a pixel area and a light permeable area. The light permeable area comprises a substrate base plate layer, an organic area, a metal area and an encapsulation layer which are arranged in sequence, all the membrane layers of the light permeable area are made from a flexible material, and the light permeable area can stretch and shrink. When the light permeable area isin a shrinkage state, all the pixels are mutually close, the light permeable area becomes smaller, and the functional area can be combined with the display area together to achieve complete display of the surface of the display panel; when the light permeable area is in the stretching state, all the pixels are away from one another, the light permeable area becomes larger, and the imaging effectof a camera under a 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...
