Abstract: A driving circuit of a display panel and a display apparatus using the same are provided. The driving circuit includes a shift register, a latch, a level shifter, a current source and a charge switch. The shift register receives a trigger signal to provide a data latch signal. The latch couples to the shift register, and receives a gray-level data to latch and output the gray-level data according to the data latch signal. The level shifter couples to the latch and provides a charge switch signal according to the gray-level data. The current source provides a charge current. The charge switch couples between the current source and a pixel of the display panel, and receives the charge switch signal to determine whether the current source is coupled to the pixel according to the charge switch signal.
