| description | A touch sensing chip for excluding an effect when a noise from a display panel affects a touch panel comprises a first switch, a second switch, a third switch, an integrator, a third operational amplifier, a control unit, and a display operation signal input terminal. The control unit maintains that the first and second switches are turned off in a time section to which a display signal is provided based on a display sink signal or the display signal and the third switch is turned on.
디스플레이 패널로부터의 노이즈가 터치패널에 미치는 영향을 배제하도록 하기 위한 터치감지칩으로서, 제1스위치, 제2스위치, 제3스위치, 적분장치, 제3연산증폭기, 제어부, 및 디스플레이 동작신호 입력단자를 포함하며, 상기 제어부는, 디스플레이 싱크신호 또는 디스플레이 신호를 기초로, 상기 디스플레이 신호가 제공되는 시구간에서는 상기 제1스위치 및 상기 제2스위치를 오프상태로 유지하고, 상기 제3스위치는 온 상태로 유지하도록 되어 있다. |
