The sub-pixel units 310 are divided into a red pixel unit 311, a blue pixel unit 312 and a green pixel unit 313, and the red pixel unit 311 is the sub-pixel unit 310 emitting red light; the blue pixel cell 312 is a sub-pixel cell 310 that emits blue light; green pixel cell 313 is sub-pixel cell 310 that emits green light. Each driving trace 320 is connected to at least one sub-pixel unit 310, and the driving trace 320 is used for connecting to a driving circuit, so that the sub-pixel unit 310 connected to the driving trace 320 is driven to emit light through the corresponding driving trace 320 by the corresponding driving circuit. The plurality of driving wires 320 are divided into a red driving wire 321, a blue driving wire 322 and a green driving wire 323; the red driving trace 321 is used for connecting the red driving circuit 331 so as to drive the red pixel unit 311 to operate through the red driving circuit 331; the blue light driving trace 322 is used for connecting the blue light driving circuit 332, so as to drive the blue light pixel unit 312 to operate through the blue light driving circuit 332; the green driving trace 323 is used to connect the green driving circuit 333 to drive the green pixel unit 313 to operate through the green driving circuit 333.

In an embodiment, referring to fig. 2 and fig. 3, each red light driving wire 321 is connected to two red light pixel units 311, each blue light driving wire 322 is connected to two blue light pixel units 312, each green light driving wire 323 is connected to one green light pixel unit 313, so that the number of the driving wires 320 can be reduced, the green light driving wires 323 can be independently connected to one green light pixel unit 313, each red light driving wire 321 is connected to two red light pixel units 311, and each blue light driving wire 322 is connected to two blue light pixel units 312, so that the human eye can sense the effect, the resolution is the maximum, the granular effect is the minimum, the driving wires 320 can be greatly reduced, the light transmittance is improved, and the diffraction is reduced.

In one embodiment, the plurality of sub-pixel units 310 are arranged in RGB pixels 31, that is, each pixel 31 includes three sub-pixel units 310, and the three sub-pixel units 310 are a red pixel unit 311, a green pixel unit 313 and a blue pixel unit 312, and are arranged in the manner of the red pixel unit 311, the green pixel unit 313 and the blue pixel unit 312. The structure design and layout are simple.

In an embodiment, referring to fig. 2 and fig. 3, the display panel 200 further includes a plurality of driving circuits 330, the plurality of driving circuits 330 are respectively connected to the corresponding driving traces 320 to control the corresponding sub-pixel units 310 to operate through the driving circuits 330 via the corresponding driving traces 320, that is, the plurality of driving circuits 330 are divided into a red driving circuit 331, a blue driving circuit 332 and a green driving circuit 333, the red driving circuit 331 is connected to each red driving trace 321 to control the corresponding red pixel unit 311 to operate, the blue driving circuit 332 is connected to each blue driving trace 322 to control the corresponding blue pixel unit 312 to operate, and the green driving circuit 333 is connected to each green driving trace 323 to control the corresponding green pixel unit 313 to operate.

In one embodiment, referring to fig. 2 and fig. 3, the driving circuit 330 is located outside the first display area 201, and the driving circuit 330 is located outside the display structure 300, so that the driving circuit 330 is prevented from shielding light, and the light transmittance of the first display area 201 is improved.

In one embodiment, referring to fig. 2 and 3, the display screen 200 further includes a second display area 202. The display screen 200 is provided with a second display area 202, which can display normally through the second display area 202, and the first display area 201 can be penetrated by light.

The electronic device 100 may be a full-screen mobile phone, and a camera of the mobile phone may be placed at a position corresponding to the first display area 201 to improve the screen occupation ratio.

In one embodiment, the first display area 201 and the second display area 202 have the same density of pixels 31. In the research, it is found that when the density of the pixels 31 in the image pickup area under the screen is different from the density of the pixels 31 in other areas, the difficulty of evaporation of the luminescent material of the display screen 200 through the mask is greatly increased. Specifically, the luminescent material of the display panel 200 is deposited by an evaporation method, and for evaporation of RGB three-color materials, a mask plate is required, and when the density of the pixels 31 in the image pickup area under the panel is different from that in other areas, the design, manufacture, and use of the mask plate are more complicated. Because the openings of the local areas of the mask plate are different, the stress problem when the mask plate is stretched and the deformation problem when the mask plate is used need to be considered, and the difficulty is brought to the evaporation process. In addition, when the density of the pixels 31 in the under-screen image pickup area is lower than the density of the pixels 31 in other areas, the display images of the corresponding area of the camera and the other areas have a certain difference, and subjectively, bad experience is brought to people. In this embodiment, the density of the pixels 31 in the first display area 201 is consistent with that of the pixels 31 in the second display area 202, so that the evaporation of the luminescent material of the display screen 200 is more convenient, and the display effect of the display screen 200 without difference is realized. Meanwhile, the light transmittance of the lower-screen image pickup area corresponding to the display screen 200 is improved.

In one embodiment, referring to fig. 4, each sub-pixel unit 310 includes a light emitting layer 3101, an anode 3102 and a cathode 3103, and the anode 3102 and the cathode 3103 are respectively disposed on two sides of the light emitting layer 3101.
