Summary:PROBLEM TO BE SOLVED: To provide a display apparatus, a display driving apparatus and a method for driving the display apparatus which prevent signals from being incorrectly transmitted to driver integrated circuits (ICs), following the driver IC connected to driving IC that has a fault, as a result that a single driver IC among the plurality of driver ICs connected in a cascade structure falls in a state of not operating normally due to faults. SOLUTION: In the display driving apparatus that outputs control signals to a number of driver ICs 210, the plurality of driver ICs are connected, in a cascade such that when a first control signal is input to a first driver IC, a transmission signal corresponding to a first control signal is transmitted to a subsequent driver IC. The display driving apparatus includes a restoration signal generating unit 430 for generating restoration signals, with respect to the first control signal and the respective transmission signals of the number of driver ICs; an error detection unit 450 for detecting the abnormal driver IC that does not operate normally from among the plurality of driver ICs; and a restoration signal output unit 440 for outputting the restoration signal to the abnormal driver IC.
