Provided are a display driving circuit, a driving method thereof and a display apparatus. The display driving circuit comprises a timing sequence control unit (20) and at least one signal driving unit (30) connected to the timing sequence control unit (20). The timing sequence control unit (20) comprises a receiving module (201), a processing module (202) and a sending module (203). The receiving module (201) receives feedback signals (FB) outputted from respective signal driving units (30) to the timing sequence control unit (20); the processing module (202) obtains a maximum delay time after comparing signal delay time of the signal driving units (30) according to the feedback signals (FB); the sending module (203) sends a second clock signal (CLK2) to respective signal driving units (30) according to the maximum delay time such that respective signal driving units (30) receive the second clock signal (CLK2) simultaneously. Therefore, delay errors of the display driving signals can be eliminated, and distortion of the display image can be avoided.
