Low power consumption of OLED displays with highly efficient sky blue

摘要

We present a 4 color pixel structure incorporating a red, green, deep blue(B) and sky blue(b) and a related driving scheme sharing a sky blue and deep blue within neighboring pixels. An addition of the highly efficient sky blue into a conventional RGB structure, namely RGBb structure, could reduce the power consumption of AMOLEDs dramatically. In a RGBb panel, using sky blue exhibited 34% lower current consumption than not using, even at full white conditions. These results were verified by fabricating a 7" LTPS based AMOLED panel. The measured results were conformed with simulated value.
