In some embodiments, the shape of the first non-display area 412 is the same as the shape of the second non-display area 424. Such as: the cross-section of the first non-display area 412 is circular in configuration and the cross-section of the second non-display area 424 is also circular in configuration.

In some embodiments, the area of the first non-display area 414 and the area of the second non-display area 424 are set to be the same, that is, the first non-display area 414 and the second non-display area 424 overlap. Such as: the cross section of the first non-display area 414 is a rectangular structure, the cross section of the second non-display area 424 is also a rectangular structure, and the sizes and rectangular areas of the two rectangular structures are the same.

It should be noted that, the area between the first non-display area 414 and the second non-display area 424 is not limited to this, for example: the area of the first non-display area 414 is larger than the area of the second non-display area 424, specifically, the surface of the first non-display area 414 is larger than the surface of the second non-display area 424, or the rectangular structure of the second non-display area 424 is spatially located within the rectangular structure of the first non-display area 414.

As can be seen from the above description, in the embodiment of the present invention, the non-display area 12 is disposed on the display panel 400, and the front-facing camera, the photoelectric sensor and other devices can be disposed at the position of the non-display area 12, so that the non-display area 12 can transmit optical signals to realize photographing and sensing functions, and the peripheral area of the non-display area 12 is the display area 11 with display function. When the display panel 400 of the embodiment of the invention is applied to electronic equipment such as a mobile phone, a pad and the like, a full screen design can be realized, and only the non-display area 12 is arranged on the display panel 400 to place a front camera or a photoelectric sensor. It should be noted that, in the embodiment of the present invention, devices such as a front camera and a photoelectric sensor may be directly embedded into the non-display area 12, so that on the basis of implementing a full screen, the space occupied by the devices such as the front camera and the photoelectric sensor by the electronic device may be further reduced, so that the electronic device is lighter and thinner.

The above is a specific description that the data line and the scan line pass through the first non-display area in the embodiment of the present invention, where the first non-display area may be located at any position defined by the scan line and the data line, and the second non-display area may be located at a position corresponding to the first non-display area. It should be noted that the arrangement of the array substrate in the embodiment of the invention is not limited thereto, and other manners may be adopted.

It should be noted that, in the illustrated example, the cross section of the non-display area 12 is a rectangular structure, which does not limit the embodiments of the present invention, but the specific shape and structure of the non-display area 12 in the embodiments of the present invention can refer to the above and will not be described herein.
