Abstract
Official abstract text for this publication.
The present invention discloses a charge-sharing type pixel structure having a first sub-pixel and a second sub-pixel that each includes a transistor. The second sub-pixel further has a third transistor and a top-gate electrode. When the third transistor is switched on, original gray scale applied to a liquid crystal capacitor of the first sub-pixel varies due to charges being shared with other capacitors. The top-gate electrode change the threshold voltage of the third transistor according to biasing signal so as to further adjust the variation of the gray scale voltage applied to the liquid crystal capacitor of the first sub-pixel.
First claim
Opening claim text (preview).
What is claimed is: 1. A charge-sharing type pixel structure comprising: a first gate line providing a first scanning signal; a second gate line providing a second scanning signal; a data line providing a data signal; a first sub-pixel having: a first transistor being connected to the first gate line and the data line and being switched on when receiving the first scanning signal from the first gate line; a first liquid crystal capacitor being connected to the first trans…
