title = "New gate driver circuit using pre-charge structure for active-matrix LCDs equipped with in-cell touch structure",
abstract = "This work presents a hydrogenated amorphous silicon (a-Si:H) gate driver circuit for active-matrix liquid crystal displays (AMLCDs) equipped with in-cell touch structure. The display operation can be paused several times in a frame with the horizontal blank driving method to increase the touch reporting rate. Moreover, the pre-charge structure is utilized to reduce the threshold voltage (VTH) shift of driving TFT during touch sensing operation. Simulation results confirm that the proposed gate driver circuit can generate reliable output waveforms after touch sensing period (200 μs) at 85 °C. The rising time and falling time are respectively maintained at 2.73 μs and 1.92 μs, demonstrating the feasibility of proposed circuit appling to AMLCDs equipped with in-cell touch structure.",

note = "Funding Information: This work proposed a gate driver circuit using HBDM for display panel with in-cell touch structure in AMLCDs, and the display operation can pause in row lines several times for high reporting rate. The proposed work can store the charges in pre-charge structure to avoid constant gate voltage stress applied to the driving TFT, diminishing the VTH shift of driving TFT during touch sensing operation. According to the simulation results, the rising time and falling time of output waveforms can be respectively maintained at 2.73 ? s and 1.92 ? s after touch sensing operation of 200 ? s at 85 oC. Therefore, the proposed circuit is suitable for the HBDM with in-cell touch panel in AMLCDs.
