Abstract: A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.

Abstract: A touch sensor employs one or more transparent conductors incorporating a random pattern of voids. The voids are arranged according to a random pattern that maintains the electrical continuity of the transparent conductive layer. The touch sensor is manufactured by depositing a layer of a transparent conductor and forming voids in the transparent conductor. Formation of the voids may be used to achieve a selected sheet resistance of the conductive layer as well as to improve optical transmission through the touch sensor.
