ORGANIC LIGHT EMITTING DIODE DISPLAY AND METHOD OF DRIVING THE SAME

摘要

A controller for a display panel may include a first supply circuit to output first and second driving voltages to a sub-pixel of a first color; and a second supply circuit to output third and fourth driving voltages to a sub-pixel of a second color. The first driving voltage may be greater than the second driving voltage, and the third driving voltage may be greater than the fourth driving voltage. Also, at least three of the first, second, third, and fourth driving voltages may be different from one another.

1. An organic light emitting diode (OLED) display, comprising:
a plurality of pixels, each including sub-pixels of different colors; a plurality of voltage supply lines to supply driving power source voltages to the sub-pixels; a signal controller to determine the driving power source voltages and to generate a voltage supply control signal including information indicative of the driving power source voltages; and a voltage supply unit to generate the driving power source voltages based on the voltage supply control signal and to transfer the driving power source voltages to the plurality of voltage supply lines, wherein the voltage supply unit generates different power source voltages for different ones of the sub-pixels.
