Abstract
While organic light-emitting diode (OLED) display devices are often calibrated upon commissioning to provide similar output colors in response to input signals, they are not calibrated based on varying display content. Significant variation in output color as a function of varying output display content is increasingly unacceptable to users. In an OLED display, an emissive electroluminescent layer selectively emits light in discrete areas in response to an electric current. Higher overall applied electrical currents correspond to higher overall output luminesces, however, as current is increased, attendant voltage generally drops. Variation in attendant voltage causes variation in output color. The presently disclosed display drivers that detect an on-pixel ratio of an input display signal, select a gamma correction factor, apply the selected gamma correction factor, and output a color-corrected display signal to the OLED display address variations in output color as a function of varying output display content.
