The past two or three years have seen a significant increase in the use of LEDs to provide a backlight for LCDs. The common LED backlight techniques will be described very briefly, but the focus of the presentation will discuss the advantages, methods and problems related to local-dimming LED backlights. Some of the LED backlit TVs on the market today use local dimming, but none that we have seen so far are fully optimized, so the improvement in display quality is barely noticeable. We have been working on a local dimming LED backlight controller for three years, and are now able to achieve a very noticeable improvement in contrast ratio, with an average power reduction around 60%, while introducing few artifacts. There will be a demonstration of a production 47” LED backlit LG TV with all the electronics (except TCON) replaced with ours.
