The future development of LED backlight

LED backlight LCD TV manufacturers will be in accordance with the idea of universal? One of the key factors of its popularity is the lower price of the LED backlight, which is much more expensive than the CCFL backlight, so the price must be reduced.

We compare the 40 inch LCD TV panel is equipped with side light type LED backlight and direct type CCFL backlight when. The fourth quarter of 2009, LED backlight is about $135, compared with CCFL backlight expensive about $90.

Now can be said with LED back light LCD TV, fell more sharply than the selling price of the CCFL backlight LCD TV more profitable. 40 inch LED backlight LCD TV, although the cost of CCFL increased by $90, but the LCD TV retail price was increased by $440.

We think will spread between LED and CCFL back light continue to shrink, 2010 in the fourth quarter will drop to about $70, the price of LCD TV can be reduced to $350. Taking into account the awareness of environmental protection, etc., consumers are likely to accept a $350 price difference. If the fourth quarter of 2011, the difference between LED and CCFL backlight can be reduced to $50, then LCD TV with LED backlight will have a leap forward.

Chip usage will be cut in half by the end of 2010

Panel manufacturers like reduction in the number of LED chips used in order to reduce the cost of back light. 2009 fourth quarter, 40 inch LCD TV side light LED backlight requires about 600 LED chips. The fourth quarter of 2010, is expected to be reduced to 300~400.

Number of reduced LED chip, need to improve the luminous efficiency and transmittance of LCD panel to achieve. The luminous efficiency of LED chips has been increased by 20% per year by 2009. After 2010 is expected to increase at a slower pace, but also due to the reduction in the cost of packaging light-emitting time to maintain an annual increase of about 10%.
