Abstract
A touch display device and a touch sensing system are disclosed. When a touch controller transmits or receives data to or from a plurality of touch driving circuits through a common line, the touch driving circuit that does not transmit a sensing completion signal to the touch controller may identify whether a malfunctioned state occurs based on an operation state when a read command is received from the touch controller and may transmit transformed sensing data to the touch controller. Accordingly, the touch controller easily identifies the malfunctioned state of the touch driving circuit and performs control according to a type of the malfunctioned state, thereby preventing or reducing the performance degradation of touch sensing due to a malfunction of the touch driving circuit.
