Abstract
The present application relates to a drive circuit of a pixel unit, and a display panel. A switch module () of the drive circuit controls connection and disconnection between a light-emitting unit () and a pre-charging module () according to a line scanning signal transmitted by a main control module (); a triggering module () controls connection and disconnection between a power supply unit () and the pre-charging module (), as well as connection and disconnection between a pre-charging power supply unit () and the pre-charging module () according to the line scanning signal transmitted by the main control module () when the light-emitting unit () and the pre-charging module () are disconnected; and the light-emitting unit () performs, when the light-emitting unit () and the pre-charging module () are connected, luminescence display under control of a power supply voltage transmitted by the power supply unit () through the pre-charging module () and a pre-charging voltage generated when the pre-charging module () is connected to the pre-charging power supply unit ().
