Assignee: LG DISPLAY CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The touch display device of claim 1, wherein the malfunctioned state is a state in which the read command is received in a state in which the sensing completion signal is not generated by the touch driving circuit,
a state in which a certain time has elapsed after the sensing completion signal is generated before the touch driving circuit receives the read command,
a state in which a difference between a time point at which the sensing completion signal is generated by the touch driving circuit and a time point at which the sensing completion signal is generated by the representative touch driving circuit is out of a preset range,
a state in which the touch driving circuit is performing sensing when receiving the read command,
a state in which a toggling number of a touch clock signal is different from a preset number when the touch driving circuit transmits the sensing data, or
a state in which the touch driving circuit reads a memory other than a memory in which the sensing data is stored.
