Patent ID: 7626565

Claim:
A display device using self-luminous elements, comprising: a reference current output unit which generates a first current adjusted depending on respective luminescent colors of self-luminous elements of a display device and outputs said first current for each of said luminescent colors, said display device being constituted by pixels in which said self-luminous elements are arranged in a matrix and displaying at least two or more colors on the basis of current value control; plural current output units which convert said first current outputted from said reference current output unit into a second current reflecting information of display gradation data sent from a signal line and output said second current to a display area side; and a first selector unit which switches an output destination of said second current outputted from said current output units to respective pixel columns corresponding to said respective luminescent colors, wherein, said reference current output unit outputs said first current in response to switching in said first selector unit, and wherein, said reference current output unit includes: plural reference current generating units which separately generate reference currents corresponding to said first current adjusted for each of said luminescent colors and output said reference currents; and a second selector unit which is connected between said plural reference current generating units and said plural current output units and outputs said reference currents depending on the switching in said first selector unit as said first current at same timing as the switching in said first selector unit.
