Abstract (en)

[origin: EP2492903A1] 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.
