<P>PROBLEM TO BE SOLVED: To provide a display device for decreasing power consumption by decreasing the driving voltage and a driving method therefor. <P>SOLUTION: An organic light emitting display device includes a panel having a plurality of pixel circuits including a light emitting element whose one end and the other end are connected to first voltage and second voltage, respectively, a control section for outputting a control signal and data signal to subtract image data of the unit of one frame and display the screen by the subtracted image data on the panel, a voltage difference setting section for detecting the highest value of the subtracted image data and calculating the difference value between the first voltage and second voltage to generate driving current corresponding to the highest value, and a power supply section for generating the first voltage and the second voltage and outputting them to the panel to establish the difference value. The driving current is the current supplied to the light emitting element. <P>COPYRIGHT: (C)2011,JPO&INPIT |
