Gate line driving circuit with top gate and bottom gate

A circuit, comprising:

• a first switching element having a first end and a second end;
• a second switching element having a first end and a second end, wherein the first end of the second switching element is coupled to the first end of the first switching element, and the second end of the second switching element is a gate;
• a third switching element having a first end and a second end, wherein the second end of the third switching element is coupled to the second end of the second switching element, and the second end of the third switching element is a gate configured to receive a pulse signal;
• and
• a fourth switching element having a first end coupled to the second end of the first switching element and an end of a first capacitor,
• wherein the fourth switching element has a bottom gate and an oxide semiconductor layer;
• and the second switching element has a top gate and a silicon semiconductor layer.
