Correspondingly, the nineteenth side 2022 and the twentieth side 2023 of the first touch electrode 202 are perpendicular to each other, i.e., the notch of the first touch electrode 202 is also square or rectangular.

In some embodiments, referring to fig. 16 and 17, the included angle between the seventeenth edge 1012 and the eighteenth edge 1013 of the trough 101 is a first acute angle. Correspondingly, an included angle between the nineteenth side 2022 and the twentieth side 2023 of the first touch electrode 202 is a second acute angle. The first acute angle is equal to the second acute angle. For example, the grooves 101 may be acute triangular. Correspondingly, the notch of the first touch electrode 202 is a part of an acute triangle.

In some embodiments, the groove 101 penetrates the array substrate 21 in a thickness direction of the array substrate 21. That is, the groove 101 may be formed in a shape of a hole, such as a circular hole, a semicircular hole, a square hole, a rectangular hole, a triangular hole, and the like. Accordingly, the functional area 100 may be provided with functional components such as a camera, a proximity sensor, and the like, so that the electronic device may implement functions such as photographing, proximity sensing, and the like through the functional area 100.
