Abstract
The present disclosure provides a driving system. The driving system includes: a voltage generating circuit configured to generate (2m+k+1) initial grayscale voltages; a ramp voltage curve generating circuit configured to generate (2m+1) ramp voltage curves by using the (2m+k+1) initial grayscale voltages based on k-bit data of received pixel data, each ramp voltage curve of the (2m+1) ramp voltage curves including 2k step voltages; a source driving circuit configured to generate additional 2n ramp voltage curves by using any two adjacent ramp voltage curves of the (2m+1) ramp voltage curves based on m-bit data of the received pixel data; and an output control circuit configured to select a grayscale voltage of the ramp voltage curves based on the received pixel data and send the selected grayscale voltage to the data signal input terminals of the pixel circuit.
