Touch sensor system and multiplexer thereof
A touch sensor system includes a touch panel having a plurality of touch sensing areas, at least one multiplexer and a touch controller. The touch controller, for controlling touch driving and sensing on the touch panel, includes a plurality of pins connected to the multiplexer via a plurality of touch control wires and touch sensing wires, wherein each of the pins is connected to one of the touch control wires or touch sensing wires. Each of the touch sensing wires transmits driving signals from the touch controller to a corresponding multiplexer to perform driving on one of the touch sensing areas, and transmits sensing signals from the touch sensing area to the touch controller. The touch controller controls the multiplexer to perform touch driving and sensing on the touch sensing areas in a specific order by triggering the touch control wires in an order.
