Latest Patents
His most significant patent is titled "Apparatus and method for writing storable images into a matrix-addressed." This patent describes a matrix-addressed liquid crystal display device that includes a display section made up of a pair of optically transparent plates. Each plate has a plurality of parallel strip electrodes that are optically transparent and deposited through an optically transparent spacer. The plates are arranged parallel to each other, allowing the electrodes to intersect at right angles, forming row and column electrode groups of a matrix. The device utilizes a cholesteric phase liquid crystal that aligns its molecular axes in the direction of the electric field when a voltage above a threshold level is applied. This innovative approach allows for a transition between nematic and cholesteric phases of the liquid crystal, enhancing the display's functionality.
