Patent ID: 7499042

Claim:
A display device comprising: a plurality of selection scan lines; a plurality of current lines; a selection scan driver which sequentially selects said plurality of selection scan lines in each selection period; a data driving circuit which applies a reset voltage to said plurality of current lines in a first part of the selection period, and supplies a designating current having a current value corresponding to an image signal to said plurality of current lines in a second part of the selection period after applying the reset voltage in the selection period; and a plurality of pixel circuits which are connected to said plurality of selection scan lines and said plurality of current lines, and supply a driving current having a current value corresponding to the current value of the designating current which flows through said plurality of current lines; wherein in the selection period, each of said plurality of pixel circuits loads the designating current which flows through said plurality of current lines, and stores a level of a voltage converted in accordance with the current value of the designating current, and after the selection period, each of said plurality of pixel circuits shuts off the designating current which flows through said plurality of current lines, and supplies a driving current corresponding to the level of the voltage converted in accordance with the designating current.
