Consumer Demand for LED Backlight Falters as Demand for LED Lighting Rises
LIGHTimes News Staff
April 3, 2014...While demand for LED chips for backlight applications in display screens is
expected to decline, both LED lighting sales and total shipments of LED chips
are increasing. According to NPD DisplaySearch, worldwide LED lighting chip
sales are expected to rise from $1.1 billion in 2013 to $3.4 billion in 2017.
The company forecasts that overall LED chip demand (measured in standard units
of 500 × 500 micron chip size) is expected to grow from 17 billion in 2012 to
61 billion in 2014. However, NPD Display Search predicts the market for LED
backlight chips for TVs and other display applications will begin declining
The company says a combination of slower growth in LED-backlit LCD TV sales
and efficiency increases have resulted in a reduction in the number of chips
used per backlight and the demand. LED backlight chip sales reached $2.0
billion in 2013, but are NPD DisplaySearch expects them to decrease to $1.4
billion in 2017. However, the company points out that consumer demand for LED
lighting has increased since 2012, and the company expects it to continue
growing through 2017.
"LED market observers have been expecting huge growth in the LED
lighting market for a long time, and it's finally here," said Steven Sher,
LED backlight and lighting analyst for NPD DisplaySearch. "Significant
growth in consumer lighting is helping to keep the LED market on an upward
trajectory, even with ongoing declines in backlight demand."

Samsung Debuts New Flip Chip LED Packages and Modules
LIGHTimes News Staff
March 27, 2014...Samsung Electronics Co., Ltd., of Seoul, South Korea, introduced a new line
of flip chip LED modules and packages. The new offerings were developed for use
in LED bulbs, MR/PAR and downlights and will be available during the second
quarter of this year.
“By utilizing an advanced flip chip technology, Samsung has made
significant improvements to its LED packages and modules,” said
Bangwon Oh, senior vice president, LED strategic marketing team, Samsung
Electronics. “Our new Samsung FC and FCOM solutions also strengthen
our overall line-up of LED component solutions, further enhancing our market
Samsung’s new flip chip on module (FCOM) solutions and flip chip (FC)
LED packages feature flipped over blue LED chips and an adhering phosphor film
on each chip. Unlike conventional LED packages that fabricated by dispensing
phosphor and then placing a plastic mold over each chip, Samsung says its FC
package technology can produce chip-scale size LED packages without any
Samsung asserts that its FC and FCOM series can operate at a higher current
than that of conventional LED components. The low thermal resistance of both
series of flip chips reportedly increases the reliability resulting in higher
flux. Thus, the number of packages needed is reduced along with the size of the
circuit board compared to traditional LED technology.
The design employs an attached cell film on each package for uniform
thickness and chromaticity control of MacAdam 3-step ellipses. The new FC and
FCOM LED solutions include an LED downlight module, a middle power LED package
(LM131A), and a high power LED package (LH141A), all featuring the new Samsung
flip chip technology.
Samsung’s LM131A and LH141A flip chip packages measure 1.22 x 1.22 mm
and 1.4 x 1.4mm, respectively. Samsung points out that excluding a plastic mold
allows the two packages to operate reliably at a high current level. Overall,
these advantages make them ideal for use in LED lighting applications requiring
high light output and a small form factor such as LED bulbs and spotlight
products including MRs and PARs. In addition, Samsung says that phosphor film
assures color quality that satisfies the MacAdam 3-step.
The new FCOM is reportedly compatible with a variety of electrical drivers
of different wattages through simply changing the number of FC LED packages.
Samsung FCOMs require a circuit with a 1.7x1.7 centimeter form factor for a
downlight with 1000lm output and 100lm/W efficacy. Samsung’s FCOMs
satisfy the MacAdam 3-step and can support MacAdam 2-step depending on customer
needs. Thanks to the superb color consistency of the chips and a color
rendering index (CRI) of at least 80. The new Samsung FCOMs also come in a
range of correlated color temperature (CCT) options – from 2700K to
5000K. These new LED solutions will be displayed at the Light + Building trade
fair in Frankfurt, Germany, March 30 - April 4 (Booth B04 in Hall 6.2).
