Application Curve

As the LED currents that are driven through the red, green or blue LEDs are increased, the brightness of the projector increases. This increase is somewhat non-linear, and the curve for typical white screen lumens changes with LED currents is shown in Figure 32. For the LED currents shown, it is assumed that the same current amplitude is applied to the red, green, and blue LEDs. For mono-chrome use case with a single LED or a different light source, this curve will be different and the specific light source documentation needs to be referred for similar information.
