Referring to fig. 4, when the first flexible circuit board 20 and the second flexible circuit board 30 are both bent to the back of the display screen 10, the orthographic projection of the first flexible circuit board 20 on the display screen 10 covers the orthographic projection of the second flexible circuit board 30 on the display screen 10.
In an embodiment, the first side is adjacent to the second side. For example, the first side is the left side and the second side is the lower side. That is, the first flexible circuit board 20 and the second flexible circuit board 30 are located at two adjacent sides of the display screen 10, so that the manufacturing process is simplified, and the production efficiency is improved. In another embodiment, the first side and the second side may also be oppositely disposed, wherein the first side and the second side are different sides.
In one embodiment, the second flexible circuit board 30 is connected to a predetermined end portion of the touch layer, the predetermined end portion being an end portion close to the first flexible circuit board 20 side. For example, when the first flexible circuit board 20 is located at the right side of the display screen, the second flexible circuit board 30 is connected to the right end portion of the lower side of the touch layer, so that the distance between the first flexible circuit board 20 and the second flexible circuit board 30 is reduced.
