Samsung LE40M91: 40" LCD TV with LED Backlight
Samsung has announced the first commercially available 40″ LCD TV with a LED backlight echewing the traditional CCFL-based backlight. CCFL has been the king of backlight but is now being challenged with LED. LED has advantages: very slow degradation of light output through 50,000 hours versus CCFL’s slow but sure decline. LED also provides much better color gamut that can exceed 100% NTSC. CCFL, with recent developments, have reached 92% NTSC with traditional CCFL’s at 72%. The LE40M91, however, limits the excitement with a low resolution of only 1366 x 768. Although DailyTech is reporting that the color gamut is 146%, I highly doubt it is that high.
