Abstract
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.
