Abstract

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.

Description

technical field [0001] The invention relates to the field of integrated electronics, in particular to a driving circuit, a driving method, a display device and electronic equipment. Background technique [0002] With the increasing requirements on the integration level of electronic equipment, display devices are usually integrated with other electronic devices into an electronic equipment. For example, a display device and a touch device are integrated into a mobile phone for realizing touch display. However, when the display device is displaying, the voltage and current in the driving signal will change with time, thereby generating electromagnetic interference. The electromagnetic interference is the noise signal of other electronic devices integrated with the display device. Contents of the invention [0003] The problem to be solved by the present invention is to provide a driving circuit, a driving method, a display device and electronic equipment, so as to reduce ...
