  • Patent number: 7791700
    Abstract: The present invention features a liquid crystal display device including a printed circuit board, PCB, substrate composed of non-conductive material and having a front surface and having an opposing back surface that contains electrical circuitry and is located near the back of the display device. A liquid crystal display is disposed on the front PCB substrate surface and includes first and second electrode layers and a dispersion layer disposed between the first and second electrode layers. The dispersion layer includes liquid crystal (e.g., cholesteric liquid crystal) dispersed in a polymer matrix. Electrical through-conductors extend between the front substrate surface and the back substrate surface. The through-conductors are in electrical contact with the first and second electrode layers. Drive electronics are disposed on the PCB substrate and are adapted to apply voltage pulses to the first and second electrodes effective to form images on the liquid crystal display.
