Abstract
The present innovation provides a system for driving an OLED pixel that includes an arrangement for driving the OLED pixel in a voltage mode and an arrangement for driving the OLED pixel in a current mode. The system includes an arrangement for switching between the voltage mode and the current mode. When a selected luminance for the OLED pixel is high, the voltage mode may be selected by the switching arrangement, and when the selected luminance for the OLED pixel is low, the current mode may be selected by the switching arrangement. A driver circuit for an OLED pixel is provided. A method of driving an OLED pixel is provided that includes driving the OLED pixel in a voltage mode when a selected luminance for the OLED pixel is high. A computer-readable medium is provided having stored thereon computer-executable instructions that cause a processor to perform a method when executed.
