Abstract
A drive circuit and a display device are provided. Changes in control electrode voltages of switching transistors do not couple a control electrode voltage of a drive transistor. The drive circuit may support different levels of image refresh frequencies at the same time, and implement seamless switching between different image refresh frequencies. The drive circuit may include a storage capacitor, the drive transistor, and the switching transistors. The drive transistor may be configured to control a drive current of the light-emitting diode, and the switching transistors may control the control electrode voltage of the drive transistor and compensate for a threshold voltage of the drive transistor. Other embodiments are described herein.
