LENS WITH PROXIMITY DETECTION PERFORMANCE IMPROVEMENT LAYER |
摘要 |
It is proposed herein to add a layer to the proximity detector lens of a smart phone. The layer, with beneficial qualities such as high transparency and high refractive index, may be seen to improve proximity sensor performance in the presence of matter deposited on an anti-fingerprint coating of the proximity detector lens. |
