Abstract
A display with integrated touch screen includes pixels distributed in an array of rows or pixels connected by row wires and columns of pixels connected by column wires defining a display area on a display substrate. The pixels can comprise mutually exclusive subarrays of pixels forming clusters. Each cluster can be independently controlled and can comprise a touch controller for sensing touches. Each pixel can include one or more micro-iLEDs. A first row wire can be driven with a display signal at the same time the touch controller senses one or more second row wires different from the first row wire. The touch controller can sense multiple row wires at a time or can receive a control signal at a frequency of no less than one MHz on a row wire. In some embodiments, the touch controller comprises a capacitance circuit in an integrated circuit separate from the display substrate.
