Programmable Transmit/Receive Pixel Array and Applications - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106192 titled 'Programmable Transmit/Receive Pixel Array and Applications
Simplified Explanation
The patent application describes electronic devices with arrays of dual function light transmit and receive pixels, which can function as both light emitters and detectors. The pixels include a photodetector structure and a vertical-cavity, surface-emitting laser diode in a common stack of epitaxial semiconductor layers. The functionality of the pixels can be altered in time, allowing for various applications such as depth sensing or autofocus within an optical display or camera of the electronic device.

Original Abstract Submitted
disclosed herein are electronic devices that include arrays of dual function light transmit and receive pixels. the pixels of such arrays include a photodetector (pd) structure and a vertical-cavity, surface-emitting laser (vcsel) diode, both formed in a common stack of epitaxial semiconductor layers. the pixels of the array may be configured by a controller or processor to function either as a light emitter by biasing the vcsel diode, or as a light detector or receiver by a different bias applied to the pd structure, and this functionality may be altered in time. the array of dual function pixels may be positioned interior to an optical display of an electronic device, in some cases to provide depth sensing or autofocus. the array of pixels may be registered with a camera of an electronic device, such as to provide depth sensing or autofocus.
