Abstract
A proximity sensing device which is disposed under the OLED panel and has an emitting module and a receiving module, is provided. The emitting module can emit an invisible light which has a peak wavelength not less than 1000 nm. The receiving module is disposed adjacent to the emitting module and can receive a reflecting light from the reflected invisible light. Therefore, the invisible light passing through the OLED panel will not cause a bright spot on the panel.
