Touch-sensitive conductive film, touch-sensitive assembly, touch-sensitive display screen and electronic device
A touch-sensitive conductive film, and a touch-sensitive assembly, a touch-sensitive display screen and an electronic device having the conductive film. The touch-sensitive conductive film comprises a sensing area and a key area. The key area is provided with a bonding area configured to bond a flexible circuit board, and a key. The key area is provided with a through-hole in a thickness direction of the touch-sensitive conductive film, and the through-hole is located at a side of the bonding area, so that the flexible circuit board is able to pass through the touch-sensitive conductive film via the through-hole. The flexible circuit board passes through the through-hole with two ends of the flexible circuit board being located at two sides of the touch-sensitive conductive film respectively, after the flexible circuit board is bonded to the touch-sensitive conductive film. In this way, the flexible circuit board would not cover the key area of the touch-sensitive conductive film, thus solving the problem that the flexible circuit board and the key interfere with each other in space, without affecting the layout design of the key. Meanwhile, an attaching surface of the touch-sensitive conductive film through which the touch-sensitive conductive film is attached onto the complete device is relatively flat, and the sealing performance of the attaching can be ensured.
