摘要： A display panel includes a substrate, a plurality of standard pixel units, and a plurality of dummy pixel units. A plurality of first conductor patterns and a plurality of shield blocks of a shield pattern layer are arranged in an array above the substrate. Each of the standard pixel units includes one of the first conductor patterns and a first shield block of the shield blocks. The first shield blocks and the first conductor patterns are overlapped, respectively. Each of the dummy pixel units includes a second shield block of the shield blocks. The second shield blocks and the first conductor patterns are not overlapped. A first edge of the substrate is spaced apart from a second edge of one of the standard pixel units adjacent to the dummy pixel units by a first distance.

摘要： 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.
