Abstract
A display driving apparatus according to an implementation of the present invention includes: a first delay circuit that generates latch control signals changing with different timings; a second delay circuit that generates falling delay signals and rising delay signals by delaying the latch control signals; a delay selection circuit that (i) selects the falling delay signals or the rising delay signals when pixel data for adjacent display output terminals have changed in different directions and (ii) selects the latch control signals when pixel data for adjacent display output terminals have changed in the same direction; and a step control circuit that drives the display output terminals with timings of the signals selected by the delay signal circuit.
