For human-eye-friendly visual performance, a logarithmic-scale dimming curve is usually implemented in LED drivers. However, for RGB LEDs, if using a single register to achieve both color mixing and intensity control, color distortion can be observed easily when using a logarithmic scale. The LP50xx device, with independent color-mixing and intensity-control registers, implements the logarithmic scale dimming control inside the intensity control function, which solves the color distortion issue effectively. See Figure 10. Also, the LP50xx device allows users to configure the dimming scale either logarithmically or linearly through the global Log_Scale_EN register. If a special dimming curve is desired, using the linear scale with software correction is the most flexible approach. See Figure 11.
