ABSTRACT:
A display apparatus having a display pixel unit including a plurality of pixels arranged in a matrix, a first driving circuit for outputting a control signal to the pixels to turn the pixels ON, the control signal depending on gray-scale information of display data, and a second driving circuit outputting a ramp waveform signal for turning the pixels on a line ON in accordance with a time-period of a scanning time-period and a scanning signal of turning the pixels on the line OFF. The ramp waveform signal includes a first ramp waveform signal and a second ramp waveform signal, and the second driving circuit outputs alternately the first and second ramp waveform signals to the pixels in accordance with the time-period of the scanning time-period.
