Patent ID: 8031160

Claim:
A shift register for driving a row of pixels of a display array, comprising: a shift register unit, having a first output terminal and a second output terminal, for receiving an activation signal, the second output terminal being coupled to the row of pixels of the display array; a first thin-film transistor (TFT), having a gate, a first electrode, and a second electrode, the gate of the first TFT being coupled to the first output terminal, the second electrode of the first TFT receiving a clock signal; and a second TFT, having a gate, a first electrode, and a second electrode, the gate of the second TFT being coupled to the first electrode of the first TFT, the first electrode of the first TFT and gate of the second TFT being not directly coupled to the second output terminal and the second electrode of the second TFT, the first electrode of the second TFT being coupled to the second output terminal, the second electrode of the second TFT being coupled to the second electrode of the first TFT, wherein a channel width of the second TFT is larger than a channel width of the first TFT.
