7-4: AMOLED Pixel Circuit using Dual Gate a-IGZO TFTs for Simple Scheme and High Speed V sub(TH) Extraction

Proposed is a fast V sub(TH) compensation pixel circuit utilizing the secondary gate effect of a-IGZO TFTs with the dual-gate structure. V sub(TH) extraction is done via the faster bottom channel, resulting in very short V sub(TH) sampling time. To verify the operation of pixel circuit, DG model of...

Description
Summary:Proposed is a fast V sub(TH) compensation pixel circuit utilizing the secondary gate effect of a-IGZO TFTs with the dual-gate structure. V sub(TH) extraction is done via the faster bottom channel, resulting in very short V sub(TH) sampling time. To verify the operation of pixel circuit, DG model of Smart-Spice is used for simulation.
