Abstract: An exemplary touch panel display includes a display panel, a backlight module, an infrared camera, and a processor. The display panel has a touch surface. The backlight module includes a light guide plate and a light source module. The light source module includes a first light source and a second light source. The first light source is a visible light source, and the second light source is an infrared light source. Light emitted from the light guide plate transmits through the display panel. The infrared camera is disposed above the touch surface. The infrared camera is to detect infrared images corresponding to infrared light that emits from the light emitting surface of the light guide plate. The infrared camera detects the infrared image correspondingly. The processor is to receive the infrared image from the infrared camera and calculate a coordinate location of the object relative to the touch surface accordingly.
