TV-use Edge-type LED Backlight Unit (BLU) Technology Advancement and Cost Saving Accelerates


Research firm Displaybank today announced that the edge-type LED BLU technology used in LED LCD TV shows a rapid advancement.

Edge-type technology that places LEDs as "Bar" type to 4-sides of the TFT-LCD panel is seeing accelerated evolution in terms of method that lowers number of LED bars used and also of cost saving. These and other findings are disclosed in Displaybank?s newly updated Large-size BLU/LED BLU Industry Trend and Analysis report, which covers backlight industry on a monthly basis.

The edge-type LED LCD TV products that was launched in year 2009 had 6 LED bars in 4-sides of panel but in 2010, products that have LED bars in only 2-side are being launched and in some small-sized application, product with 1-side 2 LED bar is being launched.

Duke Lee, Senior analyst in Display component research group at Displaybank noted "in order to decrease number of LED bars used, additional component related to heat emission is needed to be applied as well as additional LED packages; and, the area of chip work as variable. However, by lowering number of LEDs used that have high cost share, the cost of LED LCD TV models in 2010 would certainly show lower cost level than the models launched in 2009."

Displaybank forecasts that the average price of LED BLU in 2009 which was $226.10 would decline to $129.00 in 2010 that will reflect 43% price decrease based on the 40-inch sized product.

Andy Yu, Senior Vice President in Display research group at Displaybank noted "the technological advancement can be considered as the industry?s efforts to respond to the LED shortages by lowering number of LEDs applied with the cost saving factor. The explosive demand increases for LED LCD TVs lead to endless concerns on shortages for LEDs as well as other related component but major TV makers are continuously updating their new product lineup with not only LED LCD TV but '3D' LED LCD TVs."

Displaybank forecasts the market size of LED LCD TV in 2010 to be 32M units that grow 9 times Y/Y and this correspond to 19% of the total LCD TV market size.
