ELECTRONIC DEVICE
FIG2B is a schematic diagram illustrating a section along BB' of the electronic device shown in FIG2A
In some embodiments, as shown in FIG2B, the projection of the laser sensor 2 in the direction parallel to the display panel 1 is not allowed to fall on the display panel 1 by sliding down the display panel 1 or sliding up the back plate 6. In this case, the first signal emitted by the laser sensor 2 and the second signal received by the laser sensor 2 both not pass through the through hole 3 in the frame 12 of the display panel 1 nor pass through the top layer glass 10, thereby reducing consumption. Thus, the signal may be emitted with a smaller first power. Further, a larger current value may be obtained only by processing the received signal with a smaller first gain and a smaller first integral time.

['1. An electronic device, comprising: a display panel (1) comprising a display region (11) and a frame (12), wherein the frame (12) comprises a through hole (3); and a laser sensor (2) arranged to be aligned with the through hole (3) in a preset state; wherein in the preset state, the laser sensor (2) emits a first signal to a light-out side of the display panel (1) and receives a second signal through the through hole (3).', '2. The electronic device according to claim 1, further comprising: a bottom layer glass (4) arranged at a side that is above the laser sensor (2) and close to the display panel (1).']
