Patent ID: 7193592

Claim:
A display device comprising: a plurality of self-luminous elements arrayed to form a display screen; and a driving circuit which causes drive currents to flow in said self-luminous elements according to pixel signals, said driving circuit being configured to restrict the drive currents flowing in said self-luminous elements upon increase in the total sum of the drive currents, wherein said driving circuit comprises, a D/A conversion circuit which digital-to-analog converts the pixel signals; a gradation reference circuit which generates a predetermined number of gradation reference signals which are referred to by said D/A conversion circuit; and a correction circuit which detects the total sum of the drive currents flowing in said self-luminous elements and controls said gradation reference circuit to produce a predetermined number of gradation reference signals whose levels are uniformly corrected according to the total sum, wherein said gradation reference circuit includes a voltage division circuit which comprises a plurality of resistor elements connected to output a predetermined number of gradation reference voltages whose voltage ratios to a reference power supply voltage differ from each other, as the predetermined number of gradation reference signals, respectively.
