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...
This work develops a pixel circuit for in-plane switching blue-phase liquid crystal displays (IPS BPLCDs) integrated with amorphous indium-gallium-zinc-oxide thin-film-transistors (a-IGZO TFTs). The proposed circuit enlarges the range of operation voltage of BPLC by selecting different bias voltage signals to achieve maximum transmittance of BPLCs. Polarity inversion is also combined with the source...
