Today LG introduced a three-model lineup ofLCD TVs with local dimming to stand near the top of the company's HDTV lineup.
LED backlit LCDs offer superior picture quality in most ways compared to standard LCD models, due mainly to their ability to dim parts of the picture selectively--a technology known as "local dimming"--and thus improve black-level performance.

LG points out the power saving capabilities of LED technology, and the LH90 series also offers a "smart" room lighting sensor that also helps improve efficiency and automatically adjust the picture.
Unlike the flagship 55LHX model, these step-down LED sets in LG's lineup won't have a cabinet depth of less than an inch.
Pricing, as usual, was not disclosed, but LED backlightng still commands a heflt premium in most cases. The LH90 series will be available in May.
