Abstract
Various embodiments include devices, methods, circuits, data structures, and software that allow for rapid variation in the luminance of an OLED display panel. An OLED display driver circuit can include a first input, a second input, and a scaling circuit. The first input is to receive a scaling factor. The second input is to receive an image input signal including a digital representation of a desired output for a pixel. The scaling circuit is to multiply a pixel-level output voltage associated with the desired output for the pixel by the scaling factor.
