Apparatus for scan driving including scan driving units

摘要

A scan driving apparatus, includes a first scan driving unit coupled to a second scan driving unit, the first scan driving unit receives a first start signal, a first clock signal, a second clock signal, and sequentially outputs the first clock signal as a first scan, and outputs the first boost clock signal as a first boost signal, and the second scan driving receives the first clock signal, the second clock signal, a second boost clock signal, and the first scan signal as a second start signal, to sequentially output the second clock signal as a second scan signal, and sequentially outputs the second boost clock signal as a second boost signal.

1. A scan driving apparatus comprising:
a first scan driving unit configured to receive a first start signal, a first clock signal, a second clock signal, and a first boost clock signal, to sequentially output the first clock signal as a first scan signal having a first period in accordance with the first start signal applied in response to the second clock signal, and to sequentially output the first boost clock signal as a first boost signal having the first period, wherein the first scan signal changes from a first logic level to a second logic level at a start time of the first period of the first scan signal, and wherein the first boost signal changes from the first logic level to the second logic level at a start time of the first period of the first boost signal, wherein the start time of the first period of the first boost signal is delayed from the start time of the first period of the first scan signal, and wherein an end time of the first period of the first boost signal is delayed from an end time of the first period of the first scan signal; and a second scan driving unit coupled to the first scan driving unit, the second scan driving unit configured to receive the first clock signal, the second clock signal, a second boost clock signal, and the first scan signal as a second start signal, to sequentially output the second clock signal as a second scan signal having a second period in accordance with the second start signal applied in response to the first clock signal, and to sequentially output the second boost clock signal as a second boost signal having the second period.
