Abstract:
1. A same-conductivity-type channel scanning circuit, comprising: a first TFT whose current nodes are electrically connected between a first input node and an output node; a second TFT whose current nodes are electrically connected between a first potential line and the output node; a third TFT whose current nodes are electrically connected between the first potential line and a control node of the second TFT; a fourth TFT whose current nodes are electrically connected to the first potential line and the control node of the first TFT, and the control node of the fourth TFT electrically connected to the control node of the second TFT; a fifth TFT whose current node is electrically connected to the control node of the second TFT, the control node of the fifth TFT electrically connected to a second input node; a sixth TFT whose current node is electrically connected to the control node of the first TFT, the control node of the sixth TFT electrically connected to a third input node; a first capacitor electrically connected between the control node of the first TFT and the output node; a second capacitor electrically connected between the first potential line and the control node of the second TFT, wherein another current node of at least one of the fifth TFT and the sixth TFT is electrically connected to a second power supply line.
