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 game."

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 performance."

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 TFT-LCD displays.

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 representative.

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.

FDA Approves New Pulsaderm LED Blue Light Therapy Device for Acne Treatment
LIGHTimes News Staff

July 15, 2014...Pulsaderm, the U.S.-based skincare device company, announced the launch of the FDA-Cleared Pulsaderm LED Blue at the 2014 Cosmoprof North America. The FDA-approved Class II Medical Device is available for $189. Pulsaderm designed the device with blue LED technology to provide a non-invasive and painless treatment for mild to moderate inflammatory acne. Pulsaderm LED Blue reportedly offers a safe, effective, and affordable alternative with competing FDA-approved light therapy devices which often sell for well over $500. Pulsaderm has made its LED Blue into an over-the-counter version of the blue light therapy that many dermatologists use.

"We are ecstatic that Pulsaderm LED Blue has been rigorously tested and approved by the FDA," said Pulsaderm founder and CEO Yvonne von Berg. "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 products."

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."

Universal Display points out several advantages of OLED diplays compared to other displays types including a higher contrast ratio, a faster response time for video and graphics, a thinner form factor, a wider viewing angle with no degradation of contrast ratio, compatibility with alternative substrates (i.e. plastic, aluminum foil), and lower switching voltage and power consumption.

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.
