Abstract: An array substrate and a testing method thereof are provided. The array substrate includes a plurality of clock signal lines and a plurality of testing terminals. As at least two of the plurality of clock signal lines may be connected to a same testing terminal, as compared with the arrangement of the related art in which one clock signal line is connected to one testing terminal, the array substrates provided by the embodiments of the present disclosure only need to have less testing terminals, and correspondingly, the testing device that is connected to the testing terminals of the array substrate provided by the embodiments of the present disclosure may contain less pins. Therefore, the testing device can have a relatively low production cost and a relatively small volume.

Abstract: A shift register includes an output sub-circuit, a cascade sub-circuit and at least one additional output sub-circuit. The output sub-circuit is configured to transmit a first clock signal received at the first clock signal terminal to the output signal terminal under control of a potential at the pull-up node, so as to scan a gate line coupled to the output signal terminal. The cascade sub-circuit is configured to transmit a second clock signal received at the second clock signal terminal to the cascade node under the control of the potential at the pull-up node. Each additional output sub-circuit is configured to transmit a clock signal received at a corresponding clock signal terminal to a corresponding additional output signal terminal under control of a potential at the cascade node, so as to scan a gate line coupled to the corresponding additional output signal terminal.

Abstract: The present disclosure discloses a shift register, a driving method thereof, a gate drive circuit, an array substrate and a display device. With a signal control circuit, a branch control circuit, a cascade signal output circuit and at least two scan signal output circuits, each shift register can output at least two scan signals to correspond to different gate lines in a display panel. This can reduce the number of shift registers in a gate drive circuit and the space occupied by the gate drive circuit and can achieve an ultra-narrow frame design, as compared with an existing shift register that can only output one scan signal. Moreover, as signals of different output control node do not influence each other, the output stability can also be improved.
