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.
Claims14
A proximity sensing device disposed under an OLED panel, comprising:
- an emitting module, being configured to emit an invisible light which has a peak wavelength not less than 1000 nm;
- and
- a receiving module, being disposed adjacent to the emitting module and configured to receive a reflected light of the invisible light;
- wherein the emitting module includes one or more emitting elements, wherein each emitting element includes a semiconductor chip and a light converting structure, wherein the semiconductor chip is configured to emit a visible light, and the light converting structure is disposed on the semiconductor chip and includes an adhesive and a fluorescent material, wherein the fluorescent material is disposed in the adhesive to convert the visible light into the invisible light.
