Jacksonville Jaguars to Unveil Largest Ever HD Video Displays LIGHTimes News Staff
July 22, 2014...On July 26th, 35.5 million LEDs in an enormous HD LED video display will
light up EverBank Field, the home of the Jacksonville Jaguars, in Jacksonville,
Florida. During the game, the world's largest HD LED video display will be
unveilled. EverBank Field will host a soccer match between Fulham F.C. and D.C.
United followed by a concert by country music star Carrie Underwood.
"The Jaguars have done a great job in preparing an exciting unveiling
event for the world's largest video displays," Daktronics vice president
of live events Jay Parker said. "These displays will set a precedent in
professional venues in terms of the fan experience and what can be witnessed by
going to the stadium. The team can show a never before seen combination of
content with essentially three huge HD screens on one massive LED display. It's
going to be amazing when they fire them up to host their first home football
The two massive end zone displays featuring a 13HD pixel layout will each
measure 60 feet high by 362 feet wide. Each display with more than 21,700
square feet of digital canvas is longer than a football field and can feature
three full-size HD windows for maximum versatility during any event. Three
sections of 60 feet high by 106 feet wide provide enough real display space and
allow an extra 44-foot-wide buffer space for additional graphics, statistics
and other content.
The 13HD technology was selected for numerous reasons, especially its high
brightness that helps overcome the direct Florida sunlight. The displays boast
high contrast and wide viewing angles.
Natick Examines the Effects of Shelter Lighting on Soldier Thinking, Mood LIGHTimes News Staff
July 22, 2014...Researchers at the Natick Soldier Research, Development and Engineering
Center, or NSRDEC, are examining the effects of various types of lighting in
military shelters on soldiers. The Natick Soldier Research, Development and
Engineering Center is part of the U.S. Army Research, Development and
Engineering Command that aims to create technology and engineering solutions
for American soldiers.
NSRDEC's Cognitive Science Team are investigating the effect of lighting on
the ability to perform tasks, visual acuity, mood, or affective state, and
cognitive alertness/awareness. The team is comparing traditional fluorescent
lighting and newer LED lighting at varying color temperatures ranging from
low-color temperatures of yellow and red tinted white light to high-color
temperatures of bluish white. Twenty-four volunteers, soldiers between 18 and
31 years of age, participated in the five-day study,
"This study is important because it is the first study that has considered
the tradeoff between the differences in cost between the lighting technologies
and the impact of the lighting on Soldier mood and performance," Dr. Caroline
Mahoney, leader of the Cognitive Science Team, said.
"There is a ton of past research on what lighting can do to
humans," Breanne Hawes, lead researcher on the project and member of the
cognitive science team said. "It can affect how sleepy you are, your
sleeping patterns, or how productive you are. But this has rarely been studied
as a military application."
"The ultimate aim of the project is to develop efficient spaces that
promote well-being," said Hawes. "We were thinking of Soldiers in
tents doing mission planning. This is where they setup their maps and have
their meetings in shelters, and we wanted to see how the lighting would affect
that especially, among other things."
Dr. Mahoney pointed out that one of the team's goals is to help shape
technology and material development. On this study, the Cognitive Science Team
collaborated with the Shelters Team and the Special Projects Team.
"This (study) was about helping material/product developers and
designers make decisions about the technology," said Hawes. "We were
trying to analyze different lighting systems. Currently, all the tents use
fluorescent lighting, and (the Shelters Team and the Special Projects Team
members) were trying to analyze three LED systems, which are newer lighting
technologies. They were analyzing them based on technological differences, such
as how long they last and how easy they are to set up. So the goal for our
project was to tie in how (the lighting choice) is actually affecting the
people sitting under the lighting, how is it affecting the Soldiers."
Mahoney said, "Ultimately, we want to provide information to predict a
Soldier's abilities in a given context, keep them safe, and optimize
Compared with fluorescent lighting, the NSRDEC researchers found that LED
lighting in a work environment seems to promote a positive mood, increased
alertness, and faster performance on cognitive and visual perception tasks. The
researchers found that soldiers working in fluorescent lighting tended to be
more fatigued, less alert, and more depressed over time. Soldiers under
fluorescent lighting also tended to have slower response times on cognitive
tasks that measured verbal and spatial memory.
"It's important to consider how we can make things so they can perform
their best and help ensure their well-being," Hawes said.
AMOLED Mobile Phone Panel Costs to Fall Below LCD, According to NPD DisplaySearch LIGHTimes News Staff
July 22, 2014...The difference in price between AMOLED mobile phone panels and TFT-LCD
panels is decreasing, according to NPD DisplaySearch. Production yields of
AMOLED mobile phone panels have reportedly helped reduce the cost difference.
According to the NPD DisplaySearch's OLED Technology Report, the cost of
manufacturing AMOLED panels is currently 10 to 20 percent higher than that of
However, the rapid improvement in AMOLED panel production yields is expected
to result in a lower manufacturing costs for AMOLED mobile phone panels than
LCD mobile phone panels within the next two years, according to NPD
DisplaySearch. The company points out that AMOLED panels were expected to cost
less than LCD panels from close to the beginning of their use in smartphone
displays because they do not require backlighting. However, production
challenges kept AMOLED yields low, increasing production costs. Therefore,
equivalent LCDs cost less. AMOLED panels became high-end products, due to their
high-color gamut, good contrast, and slimness. Production yield improvements
are expected to help broaden the adoption of AMOLED panels into smartphones.
"Until recently, there have been few breakthroughs in the production of
AMOLED displays, and the OLED industry seemed to be facing hard times,"
said Jimmy Kim, senior analyst of display materials and LED at NPD
DisplaySearch. "If AMOLED costs fall below LCDs, as expected, it would lead
to more opportunities for the OLED display industry, greater competition with
LCD, and more choices for consumers."
The company gives the current example of a 16 percent cost difference
between 5-inch AMOLED and LCD (1920 × 1080) mobile phone panels. NPD
DisplaySearch contends that AMOLED panel costs are expected to fall below LCD
panel costs when AMOLED production yields reach 90 percent. The company notes
that if further cost reductions for OLED materials are achieved, then the yield
required for AMOLED panels to be cheaper than LCD will be even lower.
Lakewood Church Upgrades Displays with Higher Resolution Daktronics LED Video Displays LIGHTimes News Staff
July 17, 2014...Lakewood Church in Houston, Texas got two new LED video displays from
Daktronics Inc. of Brookings, South Dakota USA. Daktronics designed,
manufactured and installed two new LED video displays to replace the existing
Daktronics displays with a higher resolution display that features 4-millimeter
line spacing in a full black package.
The church uses the displays to show inspirational images and stories during
service or reveal IMAG (Image Magnification) shots as well as live video of the
sermon and song lyrics that allow the congregation to follow along. The feed
shown on the new LED displays is the same video shown on the video displays
inside the church.
The display installation continues the nine-year relationship between
Lakewood Church and Daktronics. The installation employs the existing structure
to support the new displays that measure more than 12-feet high by 22-feet wide
that replaces the two previously installed 8-millimeter pitch displays
positioned on each side of the main service platform. Installing each display
took roughly five days between Dec. 1 and Dec. 13.
"We started tearing down one of the old displays after the final service
on Sunday and had the new display installed and operational before the Saturday
service at the end of the week," said Nathan McGillivray, Daktronics
project manager of the installation. "It was critical for Lakewood to have
zero display downtime, so we installed one display the first week and the other
display the following week. Services went off without a hitch and with full
video display functionality."
"After the displays were installed, the wardrobe and makeup departments
had to be notified of everything that was now visible on the new
high-definition displays," said Joel Henie, Daktronics sales
Henie said, "A trip to the recent installation at Saddleback Church
really helped confirm Lakewood's choice to upgrade with Daktronics."
The upgrade reportedly offers image clarity and contrast that now makes
everything much more visible to the audience, from lint on clothing to blotches
of makeup and powder.

"Following the enormous success of the launch of Pulsaderm and Pulsaderm
Buddy facial cleansing brushes, adding Pulsaderm LED Blue seems like a natural
addition to the brand's growing line of affordable and effective beauty
The device employs blue light at a wavelength of 415 nanometers (nm). At the
device's light frequency and intensity, the light penetrates into the skin's
pores to activate light-sensitive porphyrins, in the outer cell membranes of
acne or acne-causing bacteria. Certain wavelengths of light cause porphyrins to
produce free radicals. These free radicals ultimately kill the acne-causing
bacteria without harming healthy skin. The device utilizes 97 non-damaging LED
lights for nearly four times as much power as most of its competitors.
According to the company, the brightness guarantees faster results for clearer,
blemish-free skin. Blue light therapy is 100 percent natural, non-invasive and
drug-free acne treatment process with no short-term or long-term adverse side
effects. The company boasts that the gentle and painless therapy reveals
visible improvements with each use.
"With innovative advancements serving as the backbone of Pulsaderm, it's
in the brand's DNA to revolutionize skincare," added von Berg. "All of
the Pulsaderm products were created in an effort to prevent and resolve
skincare problems at affordable prices. By incorporating the latest
cutting-edge technology in each product throughout the line, Pulsaderm aims to
deliver a new sense of clean."

LG Display Debuts 18-inch Flexible and Transparent OLED Panels LIGHTimes News Staff
July 10, 2014...LG display reported that it created an 18-inch, transparent and flexible
OLED panel that is rollable. The flexible panel has a high-definition
resolution of 1200 X 810 with nearly 1 million mega-pixels. The panel has a
curvature radius of 30R, and it can reportedly be rolled up to a radius of 3cm
without affecting the display's functioning. The company points out that the
new flexible OLED display proves that in the future, it can bring rollable TVs
of larger than 50 inches to the market.
Instead of conventional plastic, LG Display utilized polyimide film as the
backplane of the flexible panel to achieve the maximum curvature radius. The
polyimide film also allowed a thinner panel, which significantly improved its
flexibility. The transparent OLED panel boasts 30 percent transmittance through
the use of the company’s transparent pixel design technology. LG Display
reports that it successfully lowered the haze of the panel, which is generated
through the use of film components and circuit devices, to a level of just 2
percent. The new panel has about three times the transmittance of existing
transparent LCD panels which have a transmittance of around 10 percent.
“LG Display pioneered the OLED TV market and is now leading the
next-generation applied OLED technology. We are confident that by 2017, we will
successfully develop an Ultra HD flexible and transparent OLED panel of more
than 60 inches, which will have transmittance of more than 40 percent and a
curvature radius of 100R, thereby leading the future display
market.” said In-Byung Kang, senior vice president and head of the
R&D Center at LG Display.
