Luminosity of individual LED light sources is measured and a forward voltage control of each LED is set so that each LED has a pre-determined (e.g., uniform) luminosity at a same modulation level. The LEDs are then driven via a modulation technique such as PWM, PCM, polyphase, etc. according to lighting requirements. The LEDs are, for example, a backlight of a dual modulation HDR LCD display system, and the lighting requirements are local dimming signals for the display.
