The light-transmitting region 12, the light-receiving region 322, and the backlight region 311 may be thin-walled structures made of a light-transmitting material, or may be through holes. For example, the housing 10 is made of a light-transmitting material locally in the light-transmitting region 12, or the housing 10 forms a through hole in the light-transmitting region 12. Namely, the light can conveniently penetrate through the light guide plate in sequence.
