Цифровые обои появятся в жилых квартирах и домах уже через 2 года. Ожидается, что OLED-обои смогут заменить привычные лампочки, освещающие помещения, Oled Display.
Такие обои будут выгодно отличаться от традиционных средств освещения тем, что смогут беречь энергию. Ибо OLED - это те же светодиоды, только органические. Они примерно в 2-3 раза эффективнее, чем энергосберегающие лампы, и не хуже ламп смогут освещать помещения в темноте.Обои смогут питаться от напряжения всего в 3-5В (например, от солнечной или обычной батареи), излучая свет до 150 люмен/ватт. Конечно же, такие обои едва ли можно назвать покрытием для стен в привычном виде: они скорее будут напоминать гибкие экраны для просмотра ТВ или для презентаций.
Разработкой цифровых обоев занимается британская компания Lomox. В этом году разработчики получили грант в размере 454 тысяч фунтов стерлингов от местного фонда Carbon Trust, целью которого является поддержка развития высоких технологий, снижающих уровень выброса в атмосферу углекислого газа. Ожидается, что массовое внедрение таких обоев-экранов поможет в разы уменьшить эмиссию углекислоты.
В Lomox рассчитывают, что их технологии станут доступными уже в 2012 году. А до тех пор компании придется решить проблему стоимости технологий: при всех своих достоинствах, они слишком дороги для того, чтобы простые граждане смогли позволить себе хотя бы одну OLED-стенку.
Напомним, в России тоже собираются отказываться от энергоемких технологий в пользу более экологичных. Устаревшие лампы накаливания сменят на перспективные светодиоды. Причем в обход энергосберегающих люминесцентных ламп, устанавливатькоторые в домах россиян предполагалось ранее.

Carbon Trust backs organic LED lighting technology that promises major carbon cuts
A company developing ultra-efficient organic LED (OLED) lighting technology has been awarded a £454k grant by the Carbon Trust. The OLED materials, being pioneered by LOMOX Ltd, have a wide variety of potential applications and when coated onto a film could be used to cover walls creating a light-emitting wallpaper which replaces the need for traditional light bulbs.
As well as being flexible, OLED film will require a very low operating voltage (between 3 to 5 volts) so it can be powered by solar panels and batteries making it ideal for applications where mains power is not available such as roadside traffic warning signs.
Lighting in buildings accounts for a sixth of total electricity use in the UK. The LOMOX OLED technology promises to be 2.5 times more efficient than standard energy saving bulbs. It has been estimated that, by replacing current lighting technologies, it could reduce annual global CO2 emissions by over 2,500,000 tonnes by 2020 and nearly 7,400,000 by 2050, equivalent to a quarter of the annual carbon emissions of Wales (or the annual emissions of Birmingham).
The Welsh company aims to have the first lighting products using its technology available in 2012 and also plans to use the same technology to create more energy efficient television screens.
Mark Williamson, Director of Innovations at the Carbon Trust, said: “Lighting is a major producer of carbon emissions. This technology has the potential to produce ultra efficient lighting for a wide range of applications, tapping into a huge global market. It’s a great example of the kind of innovation that makes the UK a hotbed of clean technology development. We’re now on the look-out for other technologies that can save carbon and be a commercial success.”
Ken Lacey, Chief Executive of LOMOX, said: "LOMOX is an OLED Innovation and Development Company. OLEDs are new light emitting devices for low energy lighting and flat panel display applications. LOMOX OLEDs are more efficient, cost effective to produce and do not suffer from the oxidation defect of other polymer OLEDs, providing substantially longer lifetimes. Lighting using LOMOX OLED technology consume significantly less energy and emits less CO2 than conventional lights. We are pleased to be working with the Carbon Trust to develop this "Green" technology.”
Operating lifetime has traditionally been a problem with OLED technology, but LOMOX has found a way to achieve significantly longer lifetimes than fluorescent lamps. The technology will also be more efficient (producing 150 lumens/watt) as it only emits light along one axis. OLEDs can produce a more natural looking light than other forms of lighting.
The Carbon Trust is currently on the lookout for other technologies with significant carbon saving potential to receive up to £500k of grant funding through its Applied Research scheme. It has recently launched an open call for applications which will close on 18th February 2010. Applications can be made at www.carbontrust.co.uk/appliedresearch.
The Carbon Trust's Applied Research grant scheme has supported 164 projects from around 1900 applications and committed a total of £23m towards research worth around £55m. Approximately 65% of completed projects have, or are in the process of generating new patents, making commercial sales or receiving further investment into the development of the technology.
The scheme has provided grant funding to a wide range of renewable energy and energy efficiency technologies including fuel cells, combined heat and power, bioenergy, solar power, low carbon building technologies, marine energy devices and more efficient industrial processes.

Major Market Opportunity for OLEDs in Flat Panel Displays and Low Energy Lighting
OLEDs are considered to be today’s “ultimate” flat panel display technology because of their:
- Substantially reduced cost vs. liquid crystal displays (LCDs)
- Potential for “roll up” displays on flexible substrates
- Extreme thinness (less than 1 mm)
- Light weight
- Brilliant colours
- Low energy consumption.
The replacement of existing light sources with OLEDs will reduce energy consumption substantially (by 60%) causing a major reduction of CO2 and positively impacting the greenhouse effect significantly. Compared to LEDs and fluorescent lighting, OLEDS
- Generate more pleasing white light and better colour rendition
- Enable “design colour” on demand
- Provide new design opportunities for architects
Technology Solution
There are critical problems that exist with OLED technology in its present state. The technology is not scalable to large-sized displays (approximately >6” diagonal) at reasonable manufacturing costs. In addition, more than half the light generated is lost inside present-day OLED devices, causing the operating lifetime of screens to be unacceptably short. The OLED challenges for Low Energy Lighting are as follows:
- Operational lifetime
- Device Efficiency
- Shelf Life
- Production Costs
LOMOX® addresses these major problems through:
- Fabrication of device structures with our patented materials by a very high-yield photolithographic process similar to those in the state-of-the-art semiconductor industry.
- Use of holographically-generated nanostructures to eliminate the 50% loss of light emission in all OLED displays to date. Previous work has shown that reactive mesogen (i.e., polymerisable liquid crystal) OLED emitter materials can be photo-patterned into multicoloured display pixels with no loss in light output due to the photo-patterning process.
- Delivering emitter materials with substantially improved chemical stability and better processes for incorporating them into OLEDs.
