Abstract
Official abstract text for this publication.
Disclosed is related with a LCD technology, and particularly to a driver of promoting pixel charging ability of a thin film transistor and a method thereof. The driver of promoting pixel charging ability of a thin film transistor comprises a thin film transistor, a first capacitor and a second capacitor. The source of the thin film transistor is coupled to the first capacitor and the second capacitor respectively. As the drain voltage switches from positive polarity to negative polarity or from negative polarity to positive polarity, a voltage different between a source voltage stored by the thin film transistor and the first capacitor voltage is higher than a predetermined value. The present invention is capable of promoting the charge current and the pixel charging ability. Meanwhile, the requirement of the metal line width can be diminished to improve aperture ratio and raise transmittance of product.
