1.2: <i>Invited Paper:</i> Dynamic threshold voltage compensation IGZO‐GOA circuit for AMOLED display
摘要: A dual-gate amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistor (TFT) has been proposed and designed in this work. Based on this specific structure, a technologically advanced external Vth compensation system, where Vth can be controllable by an external DC signal source, has been developed for gate driver on array (GOA). Subsequently, the working mode of this circuit was introduced. Moreover, detailed simulation has been performed to study the appropriate process window. Finally, the proposed GOA circuit exhibited stable high-voltage output pulse, meanwhile, the lifetime showed an significant improvement with the utilization of the external Vth compensation system. It should be also mentioned that a wide pulse of 3.6ms has been obtained to sense Vth of driving TFTs in pixel circuits.

30.2: Amorphous Silicon Thin-Film Transistor Gate Driver Circuit Design with Time Division Driving Method for In-Cell Touch Display Panel
摘要: In this paper, an integrated hydrogenated amorphous silicon (a-Si:H) thin-film transistor (TFT) gate driver circuit design with the time division driving method is demonstrated for in-cell touch display panels. The design can avoid long-term biasing of the pull-up TFT in the conventional gate driver circuits and address the issues due to leakage current at Q node in the circuit during the touch sensing period. Therefore, the overall reliability of the circuit is improved. The design of the circuit is also simple without needing any additional signal inputs. As a result, the proposed circuit design can be used to pause display operation to perform touch sensing operation several times per frame, which can realize 60 Hz display scanning and 120 Hz touch reporting rate.

P-6.6: Fabrication of Cu BCE-structure IGZO TFTs for 85-inch 8K4K 120Hz GOA LCD Display
摘要: The electrical characteristics of the back-channel-etch (BCE) configuration based amorphous indium–gallium–zinc oxide (a-IGZO) (TFTs) were studied. The passivation layer ,the selection of color filter material and design of GOA TFT structure were modified for lessening the influence of H2O molecules adsorbing on the back channel of the BCE-structure. The negative and positive bias temperature stress results revealed that the optimized GOA TFTs exhibited good device reliability. Finally, a high performance 85-inch 8K4K 120Hz GOA LCD was demonstrated.
