Claim:
1. A touch sensing system comprising: a touch panel including driving electrodes and sensing electrodes defining sensor nodes; two or more touch integrated circuits that sense sensing information of each of the corresponding sensor nodes from connected sensing electrodes among the sensing electrodes by sequentially driving the driving electrodes, and transmit sensing data including the sensed sensing information of each of the corresponding sensor nodes, wherein the touch integrated circuits determine a touch generation or non-generation in an area formed by the sensor nodes, and transmit touch generation or non-generation information based on the determined touch generation or non-generation; a bridge that receives the sensing data and the touch generation or non-generation information from the touch integrated circuits, wherein the bridge aligns and combines the sensing data, collects the touch generation or non-generation information, and transmits the sensing data and a touch integrated circuit (IC) tag indicating a touch generation or touch non-generation based on the touch generation or non-generation information; a shared memory that stores the sensing data and the touch IC tag transmitted from the bridge; and a controller that detects a touch coordinate based on partial reading of the sensing data, wherein when the bridge is transmitting a possessory right signal for having a possessory right with respect to the shared memory to the controller, the bridge stores the sensing data and the touch IC tag in the shared memory, and the controller does not read the sensing data from the shared memory, and wherein when the bridge is not transmitting the possessory right signal to the controller, the bridge does not store the sensing data in the shared memory, and the controller reads the sensing data and the touch IC tag from the shared memory.
