Abstract
The present application provides a gate driving unit circuit and a method of driving the same, a gate driving circuit and a display apparatus. The gate driving unit circuit includes a shift register and a plurality of driving signal output sub-circuits. Each driving signal output sub-circuit corresponds to one of gate lines on an array substrate, is coupled to a first power supply terminal and a signal output terminal of the shift register, and also coupled to a corresponding one of driving scan signal lines. Each driving signal output sub-circuit is configured to output, under the control of a signal output by the signal output terminal of the shift register, a driving scan signal provided by the corresponding driving scan signal line or an OFF voltage provided by the first power supply terminal to the corresponding gate line.
