Abstract
A touch sensing device for preventing occurrence of electromagnetic interference (EMI) due to a clock includes a touch controller configured to operate in a write mode during a display period and operate in a read request mode or a read operation mode during a touch sensing period, and a touch driver configured to receive touch sensing data from a touch sensor during the touch sensing period and transmit the touch sensing data to the touch controller through a first bus and a second bus. The first bus is used for clock transmission in the write mode and the read request mode and is used for data transmission in the read operation mode. The second bus is used for data transmission in the write mode, the read request mode, and the read operation mode.
