Abstract
An organic light emitting diodes (OLED's) display has differently composed OLED's with respective different voltage-to-current characteristic curves. Variable power voltages are applied to the subpixels of these differently composed OLED's based on their respective voltage-to-current characteristic curves. In one embodiment, a display unit includes first subpixels emitting respective lights according to first image data representing a first color, second subpixels emitting respective lights according to second image data representing a second color, and third subpixels emitting respective lights according to third image data representing a third color, wherein the first, and second subpixels are powered by a first variable voltage power supply and the third subpixels are powered by a second and independently variable voltage power supply.
