Abstract

Abstract : This work proposes a new gate driver circuit for use in in‐cell touch panels driven with the time division driving method. The charges are stored in the inserted stage of the gate driver circuit during the suspended display operation for activating the following stage. According to the measured transfer characteristics of the amorphous indium‐gallium‐zinc‐oxide thin‐film transistor (a‐IGZO TFT), stable and uniform output waveforms can be generated after the touch sensing period.
