51.3: Driving an Adaptive Local Dimming Backlight for LCD-TV Systems

LEDs in direct‐lit backlights require new driving concepts and local dimming algorithms for an optimal efficiency and high contrast of the panel. Special measures have to be taken to control the LEDs to compensate for drift of brightness and color in order to get a picture with no critical artifacts...

Zusammenfassung:LEDs in direct‐lit backlights require new driving concepts and local dimming algorithms for an optimal efficiency and high contrast of the panel. Special measures have to be taken to control the LEDs to compensate for drift of brightness and color in order to get a picture with no critical artifacts.
