A new optical sensor from ams could enable phone makers to make display bezels even thinner, for truly all-screen designs. The optical sensor works from underneath an OLED display, similar to new technology that allows the front camera to be placed under the display. The sensor detects proximity, ambient light levels, and ambient light flicker. Most phones today have such a sensor, but need to make room for it in the bezel area above the display. The sensor incorporates several specific innovations, including compensating for display output when sensing ambient light, and dispersing infrared light from the proximity sensor to avoid activating OLED materials and introducing visible display distortion. The part is available to manufacturers now for sampling.
