摘要： An exemplary touch panel display includes a display panel, light source modules, and a camera. The display panel includes a touch surface. The light source modules are disposed on a periphery of the display panel. Light from the light source modules cooperatively forms a substantially planar illumination field. The camera is provided at a periphery of the display panel. When an object contacts or is adjacent to the touch surface, some of the light of the illumination field is reflected by the object to the camera.

摘要： A portable electronic device includes a housing defining a through hole, a barrel positioned in the housing, a lens fixed at an end of the barrel and a light detection unit fixed at the other end of the barrel away from the lens. The lens includes an imaging portion facing the light detection unit and an incidence portion facing the through hole. The incidence portion forms a reflecting surface angled relative to an optical axis of the imaging portion, such that light entering from the through hole through the incidence portion is then reflected by the reflecting surface and refracted by the imaging portion, and is then received by the light detection unit.
