Abstract:
A gate line driver circuit for a display panel includes a pull up circuit to drive a gate line of a display panel to a positive voltage that causes display panel switch elements that are coupled to the gate line to transition into an on state, a first pull down transistor to drive the gate line to a first negative voltage that causes the coupled display panel switch elements to transition into an off state, and a second pull down transistor to maintain the gate line at a second negative voltage that is less negative than the first negative voltage so as to maintain the coupled display panel switch elements in the off state. Other embodiments are also described and claimed.
