Abstract
Methods and devices for providing fast multi-touch sensors are disclosed. In an embodiment, a method is provided for design and manufacture of touch sensors for touch-sensitive devices. At least one behavioral quality is identified for the touch-sensitive devices. At least one parameter is selected, the parameter being associated with the composition or geometry of a stack of row conductors and column conductors on each of the touch sensors associated with the devices, the selection being based on the identified at least one behavioral quality. Multi-touch sensors are then manufactured by arranging a plurality of row conductors and a plurality of column conductors in a stack such that the stack or a component thereof has a geometry or composition that meets the at least one parameter. An orthogonal signal transmitter is provided for simultaneously transmitting each of a plurality of orthogonal row signals on a respective one of at least some of the plurality of row conductors. A detector is provided for detecting an amount of each of the plurality of orthogonal row signals present on each of the plurality of column conductors. Specific multi-touch sensors are also disclosed for hov…
