1. A touch sensor comprising:
a display panel configured to display an image, and comprising at least three touch sensing areas;
at least one slave processor connected to a second touch sensing area from among the at least three touch sensing areas, and configured to generate touch coordinate data for the second touch sensing area; and
a plurality of master processors connected to first and third touch sensing areas from among the at least three touch sensing areas, and configured to generate touch coordinate data for the first and third touch sensing areas, respectively,
wherein the at least one slave processor is configured to transmit the touch coordinate data for at least the second touch sensing area to any one of the plurality of master processors, or to another adjacent slave processor, and
wherein the plurality of master processors are connected to a display driving circuit through separate data transmission paths from each other to transmit at least the touch coordinate data for the first and third touch sensing areas to the display driving circuit through the separate data transmission paths, respectively.
