Driving circuit, driving method, display apparatus and electronic apparatus

摘要

A driving circuit includes: a clock signal generating unit, for generating clock signals, where transitions from first level to second level, in each clock signal, trigger a scan driving circuit to generate scanning signals, the transitions from first level to second level are defined as effective signal edges of the clock signals, and an interval between adjacent effective signal edges is defined as a clock time interval; and a control unit, for controlling clock time intervals of each clock signal to be non-identical, the clock time intervals including a first clock time interval and second clock time interval, the second clock time being longer than the first clock time, and the control unit is configured to control the clock time interval to be the second clock time interval at least once during displaying one frame of image by a display panel.
