Abstract
Optical sensing systems and methods for imaging objects include under-display optical sensors with one or multiple discrete light sources positioned on, in or under the display. The optical sensors may include an array of optical sensing elements, e.g., photodetectors, arranged in or under the display. The displays include OLED or LCD displays.
