摘要:
A pixel current driver comprises a plurality of thin film transistors (TFTs) each having dual gates and for driving OLED layers. A top gate of the dual gates is formed between a source and a drain of each of the thin film transistors, to thereby minimize parasitic capacitance. The top gate is grounded or electrically tied to a bottom gate. The plurality of thin film transistors may be two thin film transistors formed in voltage-programmed manner or five thin film transistors formed in a current-programmed ΔVT-compensated manner. Other versions of the current-programmed circuit with different numbers of thin film transistors are also presented that compensate for δVT. The OLED layer are continuous and vertically stacked on the plurality of thin film transistors to provide an aperture ratio close to 100%.

This invention presents Vt-shift invariant integrated multiplexer and de-multiplexer circuits that can be fabricated with a-Si:H, poly-crystalline silicon, or organic/polymer TFTs. The de-multiplexer and multiplexer includes a plurality of TFTs which are connected in series, and a drive TFT. These circuits are used with active matrix displays to control the gate addressing, and with imaging arrays to multiplex the read-out data.

Chiral 1-(4-methylphenylmethyl)-5-oxo-{N-[(3-t-butoxycarbonyl-aminomethyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamides as inhibitors of collagen induced platelet activation and adhesion The present invention provides chiral (2S)-1-(4-methyl-phenylmethyl)-5-oxo-(3S)—{N-[(3-t-butoxycarbonyl aminomethyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamide, and (2S)-1-(4-methylphenylmethyl)-5-oxo-(3R)—{N-[(3-t-butoxycarbonyl amino methyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamide of formula 6 and 7 respectively. The present invention also relates to use of these moieties as inhibitors of collagen induced platelet adhesion and aggregation mediated through collagen receptors. The present invention provides a process for preparation of chiral carboxamides of formula 6 and 7 using the process which has advantage to avoid any racemization at the a-carboxylic center, during N-alkylation. The reagent LiHMDS is used at low temperatures to furnish methyl N-(p methylphenylmethyl)lpyroglutamate in good chiral purity.
