The invention provides a driving apparatus for driving a display panel, including a connection pad, a selecting circuit, a data driving circuit and a detection circuit is provided. The selecting circuit is electrically connected to a data line of the display panel through the connection pad. The data driving circuit outputs a data voltage to a pixel circuit of the display panel through the selecting circuit and the connection pad in a display stage. The detection circuit provides a detection signal to a light-emitting element of the pixel circuit through the selecting circuit and the connection pad in a detection stage, and detects a resultant signal with respect to an electric characteristic of the light-emitting element of the pixel circuit in the detection stage. 本发明提供一种驱动显示面板的驱动装置，包括连接垫、选择电路、数据驱动电路以及检测电路。选择电路通过连接垫电性连接至显示面板的数据线。数据驱动电路在显示阶段通过选择电路与连接垫输出数据电压至显示面板的像素电路。检测电路在检测阶段通过选择电路与连接垫提供检测信号给像素电路的发光元件，并在检测阶段检测关于像素电路的发光元件的电性特征的结果信号。
