Abstract
A device substrate including a substrate and 1st-stage to nth-stage driver units. Each of the 1st-stage to nth-stage driver units includes a pulldown element, a reset element, and an output element. A gate of the pulldown element is used for receiving a corresponding first start signal or a reset signal. A gate of the reset element is used for receiving the reset signal. A drain of the output element is used for outputting a corresponding gate driving signal. A gate of the pulldown element of the nth-stage driver unit is electrically connected with the gate of the reset element of the nth-stage driver unit so as to make the gate of the pulldown element of the nth-stage driver unit be used for receiving the reset signal.
