Abstract: Disclosed are a display panel and a driving method therefor, and a display device. Two adjacent rows of sub-pixels are taken as a row group, and the row group is provided with a first sub row group and a second sub row group that are arranged in a column direction; a gate electrode of a first transistor in the first sub row group is electrically connected to a first gate line; a gate electrode of a second transistor in the second sub row group is electrically connected to a second gate line; two adjacent sub-pixels in the column direction share one third transistor, and a gate electrode of the third transistor in the row group is electrically connected to a third gate line; and the first transistor and the second transistor in one column of sub-pixels are electrically connected to a data line by means of the shared third transistor.

Abstract: Provided is a display substrate. The display substrate includes: a base substrate including a display region and a non-display region surrounding the display region; a gate drive circuit disposed in the non-display region; a plurality of first signal lines disposed in the peripheral region and connected to the gate drive circuit; and a plurality of second signal lines disposed in the non-display region and connected to the gate drive circuit; wherein each of the first signal line and the second signal line is configured to supply a signal to the gate drive circuit, and a frequency of the signal supplied by the first signal line is lower than a frequency of the signal supplied by the second signal line.

Abstract: An electro-mechanical gyro-balanced unicycle includes a wheel provided with a first motor, a housing provided outside the wheel and hollow pedals respectively provided at both sides of the housing. The pedal is provided with an electro-mechanical gyro assembly, and the electro-mechanical gyro assembly includes a second motor and a rotor capable of being driven by the second motor to rotate at a high speed so as to produce torques in a horizontal plane. The unicycle has a simple structure, can enable a beginner to be capable of quickly getting on the unicycle without any external assistant force, and can still well realize self-balance in left and right directions over time.
