摘要： The present disclosure is related to an array substrate. The array substrate may include a plurality of gate lines, a plurality of data lines intersecting the gate lines, and a first gate driving circuit comprising a plurality of shift register circuits in a non-active area. The gate lines and the data lines may define a plurality of sub-pixels in an active area and a plurality of dummy sub-pixels in the non-active area adjacent to the active area. The first gate driving circuit may be farther away from the active area than the plurality of the dummy sub-pixels. At least one of the dummy sub-pixels may include an auxiliary capacitor. A shift register circuit in the first gate driving circuit may be coupled to the auxiliary capacitor. The auxiliary capacitor may form at least a part of a bootstrap capacitor in the shift register circuit.

摘要： Embodiments of the disclosure provide a gate driver, a display apparatus and a method for controlling the gate driver. The gate driver comprises a plurality of clock signal terminals; a controlling signal terminal; and N stages of cascaded gate driving circuits. Each of the N stages of cascaded gate driving circuits is configured to pull-up a voltage of an outputting terminal of the gate driving circuit according to a signal at the respective clock signal terminal, and to perform a noise reduction operation according to a signal at the controlling signal terminal. A controller is coupled with the clock signal terminals and the controlling signal terminal, and is configured to detect signals at the plurality of clock signal terminals, and to output a valid level signal to the controlling signal terminal in response to the signal at the clock signal terminal being abnormal.
