By arranging the first light deflection element 1612, the transmission path of the laser can be changed. Compared with directly arranging the first laser 1611 on the side where the display surface of the display device 110 is located, the first laser 1611 with a smaller size can be changed. The light deflection element 1612 is disposed at least partially on the side where the display surface of the display device 110 is located, so that a narrow frame design of the electronic device 10 can be achieved.
