SCAN DRIVER, DISPLAY DEVICE INCLUDING THE SAME, AND DRIVING METHOD THEREOF

摘要

A scan driver includes stages dependently connected to each other, where each of the stages outputs a gate signal, where a first scanning start signal is input to a first stage of the stages, where a second scanning start signal is input to a last stage of the stages, where each of the first scanning start signal and the second scanning start signal has one pulse per frame, where the stages sequentially output a gate-on voltage between a time when a pulse of the first scanning start signal for a frame is input to the first stage and a time when a pulse of the second scanning start signal for the frame is input to the last stage, and where the stages output a first low voltage lower than the gate-on voltage after the pulse of the second scanning start signal for the frame is input to the last stage.

主权项

1. A scan driver, comprising:
a plurality of stages dependently connected to each other, wherein each of the plurality of stages outputs a gate signal, wherein a first scanning start signal is input to a first stage of the plurality of stages, wherein a second scanning start signal is input to a last stage of the plurality of stages, wherein each of the first scanning start signal and the second scanning start signal has one pulse per frame, wherein the plurality of stages sequentially outputs gate-on voltages between a time when a pulse of the first scanning start signal for a frame is input to the first stage and a time when a pulse of the second scanning start signal for the frame is input to the last stage, wherein the plurality of stages outputs a first low voltage lower than the gate-on voltage after the pulse of the second scanning start signal for the frame is input to the last stage, and wherein a second stage of the plurality of stages includes a low voltage terminal which receives a voltage having a level substantially the same as a level of a low level voltage of the first scanning start signal or the second scanning start signal, and the low voltage terminal receives one of the first scanning start signal and the second scanning start signal.
