  • Analog resistive multi-touch display screen
    Publication number: 20120001854
    Abstract: A method is provided for supporting resistive multi-touch with a touch-sensitive display screen. The display screen includes a resistive network that varies depending on where the display screen is contacted. The display screen has a first plane resistance and a second plane resistance when the display screen is not contacted. The method includes detecting one or more objects contacting the display screen. The method also includes identifying coordinates of multiple contact points on the display screen based on a change in at least one of the plane resistances. The change is caused by one or more parallel resistances created in the display screen by the multiple contact points.
