Abstract: A method for operating a gate driver that is driving pixel transistors of a display panel, is described. An internal start pulse is produced in response to an external start pulse and in accordance with a system clock, wherein the internal start pulse is input to a first cell of a gate driver shift register whose outputs are coupled to level shifting output stages that are driving the rows of pixel transistors of the display panel. The produced internal start pulse was qualified by an output of a last cell of the gate driver shift register. Other embodiments are also described and claimed.
