Santa Clara, Calif., January 18, 2012Due to lower-than-expected consumer adoption of LED-backlit LCD TVs, TV makers have changed their strategy to develop a product that utilizes less power and lowers costs. According to the recently-released NPD DisplaySearch Quarterly LED Backlight Report , set makers are reducing the number of LEDs per TV set. In turn, this also lowers brightness and moves away from the slim designs and higher picture quality that have been characteristic traits of LED-backlit LCD TVs.
LED penetration in LCD TV was 7 points lower than our forecast a year ago, mainly due to high LED premiums. The premium for a LED backlight in a 32" LCD TV was 42% in Q4'11, although it had been expected to fall to 27%, said Yoshio Tamura , Senior Vice President, NPD DisplaySearch. Therefore, TV makers are changing their strategies on direct LED-backlit TV. Instead of high picture quality, set makers have chosen low-power consumption with a corresponding lower price as selling points for this new type of LED-backlit TV. This will increase its competitiveness with CCFL-backlit LCD TV and even CRT TV.
The materials cost for direct LED backlights comes closer to that of CCFL backlights. NPD DisplaySearch estimates that for 32 LCD TVs, direct LED backlights cost 1.3-1.4 times CCFL backlights, as opposed to edge-lit LED backlights, which are estimated to cost more than twice as much as CCFL backlights. For 40 LCD TVs, the savings could be even greater, with low-cost direct backlights cutting nearly $40 in material costs, which could result in as much as $100 in savings at retail.

The cost savings come from using roughly half as many LEDs, as well as the replacement of light guide plates, optical film, and other materials with lower cost diffuser plates and lens structures on the LEDs. The reduction in LEDs and other materials lowers power consumption, but requires a thicker profile. Brightness is lowered to 300 nits as opposed to 450 nits for edge-lit LED or CCFL, and lack of dimming reduces the contrast ratio and image quality.
TV makers have been adopting 2-chip LED packages to reduce the number of packages and to reduce optical film use. The number of LED packages used per set with direct backlights is expected to be less than that of sets with edge backlights.
