Problems solved by technology

[0005] However, based on the structure of the current organic light-emitting diode (OLED) panel, and because the array substrate is multi-layered and densely packed with irregular metal lines, these opaque metal lines lead to a very low transmittance of the organic light-emitting diode panel. The existence of slit diffraction leads to a lot of stray light, which seriously affects the imaging quality of the camera under the screen
Specifically, in a traditional organic light-emitting diode (OLED) display, its driving transistor (TFT) is located directly below the light-emitting pixel unit (Pixel) it drives. Since the driving transistor includes an active layer, a gate layer, a source-drain Layers and other multi-layered metal lines, these opaque metal lines lead to a very low transmittance of the organic light-emitting diode display, and there is a lot of stray light due to slit diffraction between the small metal lines, which seriously affects the imaging quality of the camera under the screen

Embodiment 1

[0050] see figure 1 As shown, Embodiment 1 of the present invention provides a display panel 100 , which is provided with a display area 10 and an under-screen camera area 20 . The under-screen camera area 20 is any one of circle, rectangle, rounded rectangle or irregular polygon. A plurality of transistor units 1 and first light-emitting pixel units 2 driven by the transistor units 1 are arranged in the display area 10; no transistor units 1 are arranged in the under-screen camera area 20, only a plurality of second light-emitting pixel units are arranged 3, and the transistor unit 1 is arranged around the periphery of the under-screen camera area 20, and one of the transistor units 1 arranged around the periphery of the under-screen camera area 20 in the display area 10 passes through a conductive wiring 4 is electrically connected to the plurality of second light-emitting pixel units 3 .

[0051] see figure 2 As shown, wherein the under-screen camera area 20 adopts pixe...

Embodiment 2

[0069] see Figure 5 As shown, embodiment 2 includes most of the technical features of embodiment 1, the difference is that one peripheral transistor unit 1 in embodiment 2 drives more than one plurality of second light-emitting pixel units 3 When emitting light, multiple sub-pixels of the same color are connected to a corresponding transistor unit 1 at the same time, instead of connecting the sub-pixels of the same color in series first and then connecting to a corresponding transistor unit 1 in Embodiment 1.

[0070] In this embodiment, one transistor unit 1 is electrically connected to multiple red sub-pixels 31 in the same row through one conductive wire 4; one transistor unit 1 is electrically connected through one conductive wire 4 It is electrically connected with a plurality of blue sub-pixels 33 in the same row. The red sub-pixels 31 and the blue sub-pixels 33 in the same row are alternately arranged at intervals, and one conductive wire 4 connecting a plurality of r...

Abstract

The invention provides a display panel and a display device. The display device includes a display panel and a sensor. The display panel is provided with a display area and an under-screen camera area. A plurality of transistor units and first light-emitting pixel units driven by the transistor units are arranged in the display area; and only a plurality of second light-emitting pixel units are arranged in the under-screen camera area, transistor units are arranged around the under-screen camera area, and one transistor unit arranged around the under-screen camera area in the display area is electrically connected with the plurality of second light-emitting pixel units through conductive wires. According to the invention, the light transmittance of the under-screen camera area is improved,so that the light intensity passing through the under-screen camera area is improved, the photosensitive capacity of the under-screen camera in the under-screen camera area is enhanced, and the influence of diffracted light of the metal slit is reduced.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the rapid development of smart phones in the direction of full screen, the screen-to-body ratio is getting higher and higher. At present, there are notch design schemes such as iPhone X, which only reserve space on the "forehead" of the mobile phone for the front camera. , and the rest are display areas. [0003] A circular hole design is adopted in the screen, and a circular hole is opened at the position of the camera, so that the "forehead" of the smartphone is further narrowed, which is closer to the full screen than the notch screen, achieving a larger screen-to-body ratio. [0004] In order to further increase the screen-to-body ratio without destroying the integrity of the display, it is not allowed to design notch screens or openings in the effective display area of ​​the display; therefore, people think...
