Abstract
A driving device of a display device includes: a data signal line driving circuit, provided with a shift register having a level shifter for boosting a source clock signal so as to apply the source clock signal to a flip-flop, which causes a sampling circuit to directly sample a multi-gradation data signal based on each output from the shift register so as to output the multi-gradation data signal to each of a plurality of data signal lines; a control circuit for switching a full-screen display mode in which a whole of the display screen performs display and a partial-screen display mode in which only a part of the display screen performs time-sharing display; a data generating section for generating a constant voltage data writing signal made of a constant voltage; and a control circuit for outputting a selection signal for causing a nondisplay portion to directly sample the constant voltage data writing signal from the constant voltage data writing signal generation means so as to output the constant voltage data writing signal to a plurality of data signal lines. This makes it possible to provide a driving device of a display device, a display device, and a driving method of a display device, all of which make it possible to reduce power consumption in a waiting state.
