PURPOSE: A flat panel display driving apparatus is provided to gain high definition by compensating an image quality deterioration due to a signal distortion of a flat panel display apparatus generated for a feedback of a source signal and a gate signal as its screen size is increased. CONSTITUTION: A power unit(10) creates constant-voltage which is necessary to operate each components, and outputs it to a timing controller(12), a gradation generating unit(14), and a gate on/off voltage generating unit(16). The timing controller(12) creates plural data D and a source control signal SG corresponding to R,G,B as a driving data and a driving control signal, and it controls the timing and sends it to main source drive integrated circuits(18a,18b,,,18m). Simultaneously, the timing controller(12) creates a gate control signal SG and sends it to main gate drive integrated circuits(20a,20b,,,20n) by the state that timing is controlled with the source. The gradation generating unit(14) generates a number of gradation voltage corresponding to the value of the data D and applies it to the main source drive integrated circuits(18a,18b,,,18m). The gate on/off voltage generating unit(16) applies a gate turn on voltage and gate turn off voltage to the main gate drive integrated circuits(20a,20b,,,20n). A liquid crystal panel(26) represents a predetermined screen by the source signal and the gate signal applied from the main source drive integrated circuits(18a,18b,,,18m) and the main gate drive integrated circuits(20a,20b,,,20n).
