Abstract

A display device includes: a light-emitting block including a plurality of light-emitting elements for emitting N number of different basic colors; an input circuit for receiving an input data representing a first color, a second color and a third color; a converter for converting the input data into an output data representing N number of basic colors; and a controller for controlling ON/OFF states of the plurality of light-emitting elements according to the output data. N is an integer of 4 or higher.
