A novel thin planar latching switch device, generally based on a layer of polymeric switching materials sandwiched between two electrical planar conductors operative as electrodes. The device behaves as a bi-stable switch. Furthermore, the switch device generally shows a memory effect. In the open state, when no voltage is applied to the electrodes, the switching material is effectively an insulator. When an electric field greater than a certain threshold level is applied to the switching material, the material becomes more conductive, and the device thus essentially becomes a closed switch. Applications of such switching devices are described for use in flat panel displays, generally based on liquid crystals, in high efficiency color displays, and in touch screens.
