DISPLAYS & LEDs Inventories of LCD-equipped products on the rise
Inventories ofmost electronic products using large-sized liquid crystal display (LCD) panels increased inMarch and April due to slower sales of some oldermodels and the arrival of new products fromtelevision and notebook PC brands, spurring a price reduction, according tomarket researcher iSuppli Corp.
Global channel inventories of televisions rose to 4 weeks in
March, up from2.5 weeks in January. For notebook PCs, inventories increased to 4.8 weeks inMarch, up from3.5 in January. Inventories ofmonitors increased to 4 weeks inMarch, up from2.5 in January.Most of these inventories are increasing again in April.
“Even with the increase in inventories, stockpiles of LCD-TVs in
the United States remain at normal to healthy levels suitable to support televisionmakers’ efforts to clear out oldermodels and to add new products to their product lines,” said Sweta Dash, senior director for LCDs at iSuppli. “However, channel inventories for televisions in China now equate tomore than two weeks, higher than the normal level. This is leading to some cuts in panel orders and is resulting in a softening of panel demand in April, especially fromChina.”
In the United States, television brands have been introducing
BROAD RANGE OF BACKLIT LCDS AVAILABLE
Tomeet the increasing demand for LED backlighting in the industrial LCD market, Optrex America Inc. has developed one of the broadest lines in the industry of TFT LCDs with white LED backlights.
These displays feature longer lifetimes (an average of 60,000 hours),
with front of screen brightness levels ranging from400 cd/m2 to 700 cd/m² for indoor use and 800 cd/m2 to 1500 cd/m² for outdoor applications. Additional features include wide viewing angles up to 160°, high contrast ratios up to 1000:1, and wide operating and storage temperature ranges. Available display sizes include 2.0”, 3.0”, 3.5”, 4.3”, 5.0”, 5.7”, 6.5”, 8.4”, 10.4”, 12.1” and 15.0” diagonal, with a variety of resolutions to choose from.
Optrex LED-backlit LCDs offer numerous advantages over
conventional CCFL-backlit LCDs, including no warm-up time at low temperatures, lower power consumption, higher dimming ratios and, because they do not require high-voltage and high-frequency inverter circuits, significantly reduced electro-magnetic interference (EMI). And since LED backlights contain nomercury, these displays offer amore environmentally friendly option as well.

new 3-Dmodels. The price differential between equivalent- featured LED-backlit LCD-TVs and LED-backlit 3-D TVs has narrowed to as little as $300, spurring consumer demand. Brands will continue to introduce 3-D TVs globally through July.
Brands in the United States also continue to add newLED-backlit
LCD-TVs. The number of LED-based LCD-TVmodels reachedmore than 140 inMarch,more than double the number ofmodels in February.
