Abstract
Cameras are located within the display area of a display. In-display cameras allow for thinner display bezels. In-display cameras allow for the creation of ultra-high resolution images. The ability to capture an object from multiple perspectives allows for holographic image recording and playback. Multiple views of an image can be captured with varying depths of focus, allowing an image's depth of field to be adjusted during post processing. In-display cameras can also be used for user authentication, touch detection and three-dimensional gesture recognition. Thermal sensors located within the display area allow for control of the display temperature, improved control over system performance, and compensation for micro-LED degradation that can occur due to aging or increased temperature. Microlens assemblies located above pixels can adjust the viewing cone angle of the display or a portion of the display and microassemblies located under individual pixels or pixel arrays can adjust a viewing angle.
