| Abstract: | A liquid crystal neuron array with 8×8 neurons which can implement optical subtracting and thresholding parallel has been fabricated. It operates in parallel, that is, all the pixels of input are processed together simultaneously. The device is based on amorphous silicon photoconductor and features of liquid crystal rather than VLSI. So it can have higher aperture ratio, higher resolution and higher space bandwidth product. |
