Samsung, Freescale partner on white LEDs to go green

With the growing emphasis on ROHS (reduction of hazardous substances) and energy efficiency in the electronics industry, it's no wonder that LEDs are replacing fluorescent lamps for backlighting LCDs. So expect to see more partnerships like the one that Samsung and Freescale Semiconductor just entered into, with Samsung providing the glass (and some sweet moolah for custom parts) and Freescale bringing its LED drivers to the party. Heck, we figure even the cheaper white LEDs make it easier to achieve uniform illumination across the screen and higher contrast ratios, which get high marks around the Engadget HD offices; for folks not obsessed with picture quality (yeah, they're out there), LEDs offer up lighter and thinner displays.

I wish manufacturers were more forthcoming about how many LEDs (or CFLs) are in each set. Dynamic contrast ratio works by lowering the light output in one part of the screen over the other to increase the contrast between light and dark but it doesn't say how many lights are doing it. Less LEDs means more bloom, especially on star fields, or other scenes that have bright light on a dark backdrop.

Hey! We who obsess over picture quality, have a good reason to do so! I work in color management and when i see any screen with anything but perfect calibrated color... I cringe and hiss....
