Abstract: The present disclosure relates to a device and a system for testing flatness. The device for testing flatness includes a base, a testing platform, and a ranging sensor. The testing platform is assembled on the base. The testing platform includes a supporting structure. The supporting structure is disposed on the side of the testing platform away from the base and is used to support a to-be-tested board. The structure matches the structure of the to-be-tested board. The ranging sensor is disposed on the side of the testing platform away from the base. After the to-be-tested board is placed on the testing platform, the ranging sensor is used to test distances between a number N of to-be-tested positions on the to-be-tested board and the ranging sensor, to obtain N pieces of distance information, and the N pieces of distance information are used to determine the flatness of the to-be-tested board, where N is an integer greater than 2. According to the embodiments of the present disclosure, the flatness of the glass substrate can be tested to improve the manufacturing process to reduce the flatness of the glass substrate, and avoid the problem that the glass substrate is easily broken when entering the subsequent process equipment and the process equipment is down.

Abstract: A shift register, a driving method, a gate driving circuit, and a display device are provided. The shift register includes an input circuit and an output control circuit. The input circuit transmits a first signal from a first power terminal or a second signal from a second power terminal to the output control circuit under control of an input signal, a first clock signal and a second clock signal. The output control circuit transmits the first signal from the first power terminal or the second signal from the second power terminal to a signal output terminal under control of the first clock signal and the second clock signal. The input signal input to the shift register is delayed and output to a signal input terminal of a shift register in a next row.
