Taiwan-based LED packaging houses, mainly Everlight Electronics, Lextar Electronics and Unity Opto Technology, are set to start producing 15mm OD (optical distance) backlight units (BLUs) specifically for use in direct-type backlit Ultra HD LCD TVs at the end of 2013, according to Taiwan-based supply chain makers.
15mm OD BLUs can reduce the thickness of direct-type LED-backlit LCD TVs, and the number of LED chips used in Ultra HD TV BLUs is 1.5-2 times that for Full HD models of the same size, the sources said.
As China- and South Korea-based vendors have been promoting direct-type LED-backlit LCD TVs, related models are expected to account for 70-80% of Ultra HD LCD TVs in 2014, the sources indicated.
Lextar posted consolidated revenues of NT$1.167 billion (US$39.4 million) for November, growing 10.2% on month and 49.52% on year, and NT$12.636 billion for January-November, rising 35.39% on year. Currently, Lextar has 70% of consolidated revenues coming from LED backlighting and 30% from LED lighting.
