Abstract
A display driver and a display device including the same include multiple circuit blocks, each of which generates a signal representing, through time division multiplexing, voltage values corresponding to brightness levels indicated by respective K pixel data pieces as a drive signal, and generates first to Qth pixel data signals representing the K pixel data pieces with Q signals by time division multiplexing at least one pair of pixel data pieces consisting of two data pieces from among the K pixel data pieces. Each of the circuit blocks converts the first to Qth pixel data signals into first to Qth gradation voltages, for each of horizontal scanning periods, generates a gradation voltage signal representing, through time division multiplexing, voltage values corresponding to the respective K pixel data pieces expressed by the first to Qth gradation voltages, and outputs a signal amplified from the gradation voltage signal as the drive signal.
