We have developed an innovative liquid crystal display (LCD) which includes a resistive type touch screen system — integrated touch screen panel (iTSP). It can detect touch events and locate touch positions by measuring voltage at the contact point between indium tin oxide (ITO) coated color filter glass and ITO conductive isotropic film. iTSP shows not only better display qualities outside but also considerable decreases in weight and thickness compared to conventional resistive touch screen panel which consists of ITO glass and conductive film. In this paper, main characteristics of 7.0″ WVGA LCD Panel integrated with the touch screen function were presented and the optical characteristics also were discussed.
