Abstract
The present invention relates to a shift register having a plurality of stages electrically coupled to each other in series. Each stage includes a first and second TFT transistor. The first TFT transistor has a get electrically coupled to the output of the immediately prior stage, a drain electrically coupled to the boost point of the stage, and a source configured to receive one of the first and second control signals. The second TFT transistor has a get electrically coupled to the output of the immediately next stage, a drain and a source electrically coupled the drain and the source of the first transistor, respectively.
