NEC LCD Technologies Develops White LED-Based LCD Module
 NEC LCD Technologies, and its sales and marketing channel in the Americas, NEC Electronics America, Inc., has developed a new amorphous-silicon color thin-film-transistor (TFT) liquid crystal display (LCD) module that achieves an ultra-wide color gamut for 100 percent of the Adobe RGB color range by incorporating a newly developed LED light-source unit into the backlight system and a newly developed color filter.
The white LED that serves as the light source for the backlight unit in this LCD module achieves its white light by mixing light generated through the irradiation of red, green, and blue (RGB) phosphors with light from a near-ultraviolet LED chip (excitation), making it superior to traditional white LEDs in terms of color-rendering properties. Combining these newly developed white LEDs with newly developed color filters, optimized for this application, makes it possible to reproduce a wider range of colors covering 100 percent of the Adobe RGB color range, which is generally beyond the reach of conventional standard white LEDs.
In recent years, there has been an increase in customer demand for LCD displays using white LEDs as light sources in backlight units due to the many benefits achieved with LED backlight systems versus cold-cathode-fluorescent-(CCFLs)-based backlights. Such benefits include smaller module dimensions, lighter-weight designs, and reduced power consumption. The LEDs are also mercury free and do not require the use of high-voltage circuitry, allaying concerns related to safety and the generation of harmonic currents and high-frequency noise. The LEDs offer superior vibration and shock resistance as well as superior characteristics with respect to low-temperature startup and a wider dimming range.
The white LEDs currently in widespread use typically have weaker output in their red and green wavelength components than CCFLs, since they create white light by exciting the yellow phosphors that cover the blue LED chips. For this reason, when used as backlight light sources, traditional white LEDs, even when combined with color filters having a wide color gamut, impose limits on the expansion of the red and green color reproduction range, making it difficult to cover the Adobe RGB color range.
NEC LCD Technologies overcame these problems with its newly developed LCD module that is compatible with applications requiring an ultra-wide color gamut, a capability difficult to achieve with traditional white LEDs.
Longer Life Materials Deliver High Performance for Solution Process OLED Display Manufacturing
 DuPont Displays has developed a new, proprietary third generation (Gen 3) solution-based OLED materials technology, which has led to substantial performance gains for printable OLED light-emitting materials. A DuPont Gen 3 green OLED material achieved a record lifetime of over 1,000,000 hours, while two new Gen 3 solution blue materials have been developed that set new standards for longevity and color. Gen 3 OLED materials can meet or exceed the performance of today’s vapor deposited materials and are paving the way for lower cost solution process OLED displays.
“Printing OLEDs significantly lowers the cost to manufacture displays, and with Gen 3 materials technology, display manufacturers can see the material lifetimes and performance required for commercialization,” said William Feehery, global business director, DuPont OLED Displays. “With lifetime five times better than just two years ago, these new materials will allow solution OLEDs to be used in mobile displays, and also to begin to penetrate the television and general lighting markets at a lower cost than today's evaporated OLED technology.”
The new Gen 3 green material developed by DuPont represents a major lifetime milestone of one million hours, which equates to over 100 years of constant usage. This green material demonstrates a current efficiency of 25 cd/A and excellent color coordinates (0.26, 0.65). Although green material lifetimes already exceed those of red and blue, the significance is that in a display, green contributes more to the white brightness. The longer lifetime also can lead to an increase in total display lifetime.
 Historically, performance of blue light-emitting materials has been the most challenging, however, DuPont Gen 3 solution blue materials are demonstrating world-class performance. One of the Gen 3 blue materials has color coordinates of (0.14, 0.12), a current efficiency of 6.0 cd/A, and a lifetime of 38,000 hours from 1,000 cd/m2, which is one of the longest blue OLED material lifetimes publicly reported. A second material has been developed with exceptionally deep blue color coordinates of (0.14, 0.08), a current efficiency of 3.9 cd/A, and a lifetime of nearly 7,000 hours. Due to its deep blue color, the lifetime of this material at the luminance required for a 200 cd/m2 display is calculated to be approximately 41,000 hours.
In addition, a high-performing red solution OLED material developed by DuPont has a lifetime of 62,000 hours, current efficiency of 13 cd/A, and color coordinates (0.68, 0.32).
Lifetime refers to the time it takes for the luminance of the device to decrease to half the initial value, expressed at hours from 1,000 cd/m2 at 21-22C. DuPont lifetime estimates are consistent with industry standards and are based on accelerated testing of simple test devices at several very high initial luminance levels; these data are used to calculate predicted lifetimes at lower brightness levels.
“DuPont Gen 3 technology is creating a step change in the lifetime of OLED materials and also is expected to benefit future material developments,” said Feehery.
Peace Bridge Shines With LED Lighting Transformation By Philips
 Proving that city landmarks and structures needn’t go dark to be energy conscious, the Peace Bridge has undergone a 21st century transformation made possible by advanced LED technology.
The $1.2 million project was funded by the federal government’s Transportation Enhancement Program, with support from the Buffalo and Fort Erie Public Bridge Authority.
Formerly lit by metal halide floodlights that had fallen into disrepair, the 3,580-foot bridge is now illuminated by nearly 700 tri-color LED lighting fixtures – each capable of digital control to produce millions of colors and dynamic sequences. Unlike conventional light sources, they don’t require maintenance-intensive gels, filters or color scrollers to customize the bridge’s appearance on the fly for special events and holidays. More importantly, the entire LED installation will consume one third the energy of the previous system – reinvigorating the signature bridge in a smart and sustainable way.
“At the turn of the last century Buffalo was known as the ‘City of Light,’ recognizing its status as one of the first cities to be illuminated by hydro-electric power. The Peace Bridge Authority is pleased that over 100 years later we can deliver a project that builds on this heritage, utilizing state of the art technology and energy efficiency,” said Ken Schoetz, vice chairman of the Peace Bridge Authority.
“The interplay of light with a signature landmark serves much more than decorative purpose. It should reinforce the form, content and volume of the object as well as reveal the essential character and nature of the architecture,” said Paul Boken, senior lighting designer at Mulvey & Banani International. “For the Peace Bridge, LED technology allowed us to transform a static monument into a vibrant, ever-changing form – all while meeting budget requirements and the need for sustainability, security and versatility.”
“We’re thrilled to bring the extraordinary impact of LED lighting to this important landmark, demonstrating that energy-saving lighting upgrades can be both practical and visually spectacular at the same time,” said Jeff Cassis, CEO of Philips Color Kinetics. “This installation perfectly exemplifies the large-scale exterior applications that LED technology now allows – enabling the use of vibrant color where it was previously impractical, while simultaneously alleviating energy and maintenance concerns.”
In addition to their aesthetic versatility, LED systems are highly durable and therefore well suited for difficult-to-access and vibration-prone environments, such as bridges. For the Peace Bridge installation, a combination of ColorBlast® Powercore and ColorReach Powercore was specified – the former illuminating the deck of the bridge and structure below, and the latter applied to illuminate the bridge’s arches.
High-Power, White-Body, PAR30-Style Narrow-Beam LED Bulb Uses 9 Watts to Replace 50-75-Watt Halogens, Runs on Wide Voltage Range
 LEDtronics has released the latest addition to its series of high-power PAR30-style LED spotlight bulbs. The white-body, medium-beam PAR30 LED bulb is made up of five 3-watt LEDs and replaces filament-based PAR30 bulbs, combining advanced LED technologies, standard 26 mm Edison screw-in base and light optimizing design, producing 337 lumens of vivid warm-white light.
The 25°-beam PAR30A LED bulb runs on a voltage range of 85 V to 260 V AC current, and thus can be used anywhere in the world. Other voltages like 12 V AC or DC are optionally available for qualifying customers. The PAR30A-style lamp is a direct screw-in replacement for 50 W to 75 W PAR30 incandescent or halogen bulbs, but typically has a maximum power draw of 8.5 watts. With up to 85 percent energy savings, high shock/vibration resistance and long-lived, high-power white LEDs —lasting up to 50,000 continuous hours —the savings will quickly add up. The PAR30A LED lamp is available in 3,000 K warm white color temperature, provides about 40 lumens per watt (at 141 mA) and has a high color-rendering index of 83.
Since it uses LEDs instead of standard filaments, this energy-efficient bulb never gets hot and is safer and more economical than halogen bulbs, making it well suited for floodlights and other household and commercial light fixtures.
Designed for customers requiring the highest levels of brightness and efficacy, the new white-body PAR30A bulb has a wide range of applications: Recess or track lighting, accent lighting, general area lighting, architectural and landscape lighting, display-case fixtures and cabinet lighting, signage spotlighting and backlighting, aerospace lighting systems, industrial OEM equipment lighting, biomedical applications, and truck-bay dock lighting, to name only a few.
The LEDtronics PAR-30A bulb complies with RoHS, the lead-free and mercury-free directive, as well as the CE safety assurance. It is well suited for use with alternative or renewable energy resources – solar and wind power. Since it produces no harmful ultraviolet or infrared rays, it reduces light pollution, and it is compatible with the international “dark skies” initiative.

Its oval radiation pattern delivers directed light, ideal for street lighting, and its integrated lens significantly reduces the overall effort for this application.
Golden Dragon oval Plus has been developed as an easy-to-use LED solution specifically for street lighting applications. With its unique oval beam characteristics (80° vertical, 120° horizontal) and integrated long-life silicon lens, it provides energy-efficient street lighting with minimal light pollution. The light is directed precisely on the area to be illuminated with no upward stray light.
Since different roads call for different lighting environments, Golden Dragon oval Plus LED is available in various white tones with an efficiency of 90 lm/W in cold white (6,500 K color temperature) and 80 lm /W in neutral white (5,000 K). The warm white version with a color temperature between 2,700 and 4,500 is ideal for any lighting scenario where a warm and welcoming atmosphere is required, such as in a historic city center. At 4,500 K it achieves an efficiency of 65 lm/W and produces an aesthetically pleasing warm white light.
The main feature of the Golden Dragon oval Plus LED is its integrated lens. The lens makes secondary optics unnecessary, while enabling street lighting applications to be realized with much less effort, delivering unprecedented application efficiency from an LED component. The LED is also suitable for standard solder processes.
“Our new ‘street lighting LED’ combines various lighting benefits in one innovative package. It is highly efficient, and has a long lifetime due to its silicone lens. Additionally, it offers good visibility at night because the LEDs can be arranged in the system to distribute the light accurately, delivering light where it is most needed. This new light source also makes it easier to upgrade current systems to more efficient street lighting with LED technology,” said Dr. Markus Klein, head of SSL Product Development at Osram Opto Semiconductors.
The Golden Dragon oval Plus is suitable for all applications that call for efficient lighting with a homogenous oval light pattern, particularly street and tunnel lighting. It meets all the requirements for homogenous illumination. The LEDs are also lead-free and mercury-free, making them a suitable solution for the future of more energy efficient, environmentally friendly outdoor lighting.
