Abstract
A gate driver includes a plurality of stages, a memory and a selector. The plurality of stages provides a plurality of gate signals to a plurality of gate lines. The memory receives a gate input signal applied to at least one of the stages and outputs the gate input signal as a selection signal. The selector outputs a vertical start signal to a scan start point among the stages based on the selection signal.
Claims19
A gate driver comprising:
- a plurality of stages to provide a plurality of gate signals to a plurality of gate lines;
- a memory to receive and store a gate input signal to be applied to at least one of the stages and to output the gate input signal as a selection signal;
- and
- a selector to output a vertical start signal to a scan start point among the stages based on the selection signal,
- wherein the memory comprises:
- a first memory to store a first gate input signal to be applied to at least one of the stages and connected to a first start stage corresponding to a first scan start point;
- and
- a second memory to store a second gate input signal to be applied to at least one of the stages and connected to a second start stage corresponding to a second scan start point.
