Abstract
Disclosed is a driving apparatus of a flat panel display. The apparatus comprises a signal processing device for outputting display data, gray scale voltages, a gate On/Off voltage, a source control signal and a gate control signal with a driving data, a driving control signal, and a driving power source; a main source driver IC for generating and outputting a source signal; a main gate driver IC for generating and outputting a gate signal; a display panel for displaying an image; a source feedback unit arranged along a row direction of the display panel that is opposite said main source driver IC, for detecting distorted amount of a source signal output from a pixel placed at the last row of a source line connected to the main source driver IC and feeding back a first compensation signal corresponding to the distorted amount of the source signal to the pixel at the last column; and a gate feedback unit arranged along a column direction of the display panel that is opposite said main gate driver IC, for detecting distorted amount of a gate signal output from a pixel placed at the last column of a gate line connected to the main gate driver IC and feeding back a second compensation signal corresponding to the distorted amount of the gate signal to the pixel at the last row.
