Abstract:
An integrated touch screen and display device includes a polarizer with a layer of transparent conductive material deposited thereon. A touch screen controller is coupled to electrodes of the transparent conductive layer to detect the location of touches by, for example, a finger or stylus. A method for producing an integrated touch screen and display device includes applying a transparent conductive coating to an outer surface of a polarizer of a display device, creating electrodes in the conductive coating, and coupling the electrodes to a touch screen controller. A double super twisted nematic display that includes a capacitive touch panel integrated into a compensation cell of the display is also provided herein.
