ABSTRACT:
A display driving apparatus includes: n level shift units shifting a voltage level of n pixel data; a step potential providing unit providing a step potential; a change judgment unit judging whether or not each of the n pixel data has changed from pixel data of an immediately previous cycle; a delay unit generating n timing signals changing with different timings; and a control unit performing control such that the display output terminal corresponding to the pixel data judged to have changed by the change judgment unit is provided with: the step potential provided by the step potential providing unit during a first time period included in each of the cycle; and a potential shifted by the corresponding level shift unit during a second time period that is different from each other and is based on a timing of change of the corresponding timing signal.
