Abstract: An electro-optically controlled active-matrix system comprises a system substrate, row wires extending in a row direction disposed on the system substrate, a row controller providing a row electrical signal to each row wire, column light-pipes extending in a column direction disposed on the system substrate, a column controller providing a column optical signal to each column light-pipe, and pixels disposed over the system substrate. Each pixel can comprise a pixel circuit that is uniquely responsive to a row wire and to a column light-pipe, the pixel circuit receiving the row electrical signal from the row wire and receiving the column optical signal from the column light-pipe. In some embodiments, column wires carrying column electrical signals extend in a column direction over the system substrate and the pixel circuit is capacitively coupled to the row wire, the column wire, or both.

Abstract: A novel Passive Color Night Vision (PCNV) that provides a fully integrated dynamically controlled passive color night vision algorithm to work in both daylight or in low light conditions. The PCNV can dynamically switch or adjust between lighted vision and night vision. The PCNV is a passive solution that does not require active illumination by the use of an IR emitter diode as found in the prior art night vision solutions. Visible and IR spectrum composite image data manipulation is performed to achieve true color in low light conditions.

Abstract: An electronic device may include an array of pixels. Each pixel may include a first single photon avalanche photodiode circuit that generates a first output signal on a first conductive line, a second avalanche photodiode circuit that generates a second output signal on a second conductive line, and a logic NAND gate having a first input coupled to the first conductive line, a second input coupled to the second conductive line, and an output coupled to an output line. The logic NAND gate may generate a third output signal based on the first and second output signals that is independent of dark current generated by the avalanche photodiodes. The third output signal may be processed to generate range values that are further processed to generate three-dimensional images of a scene.
