The invention discloses a fail operational redundant digital resistive touchscreen. Alternating touchscreen conductors in each layer of a touchscreen display are connected to separate touchscreen controllers. Each controller completely and separately resolves a location anywhere on the display so that a failure of either controller, or the failure of conductors connected to either controller, do not degrade touchscreen usability. Conductors in separate layers, connected to separate controllers may be isolated via insulators to prevent undesirable shorts. Conductors are shaped to minimize the area covered by insulators and maximize the area of useful conductor overlap. 故障运行冗余数字电阻式触摸屏。触摸屏显示器每层的相互交错的触摸屏导体与独立的触摸屏控制器相连接。每个控制器完全独立地解析显示器上的每个位置，以使控制器的故障或者与控制器相连接的导体故障不降低触摸屏的性能。与独立的控制器连接的独立层中的导体通过绝缘体被隔离，以防止不期望的短路。导体被构形以使绝缘体的覆盖区域最小化，使有用导体覆盖物区域最大化。
