This new technology might obliterate the LED market

A new technology in its nascent form is about to hit the display market, and it has the potential to push LED, LCD and its entire family into history.

Prysm is a San Jose based private firm which has spent the last five years developing an innovative technology called Laser Phosphor Display (LPD).

Unlike the previous family of displays, LPD is a new category of large displays. It offers flexibility, scalability, better lifetime and high quality image resolution. The technology is expected to leave a much less carbon footprint than LED lights and is therefore being promoted as a greener alternative as well.

To further the claim of LPD proponents, the electricity it consumes is about 1/20th of that of a standard LED light

Essentially, the fundamental components of the system are solid state lasers and a phosphor screen. As the modulating lasers scan across the screen, phosphors emit red, green and blue colors to create a seamless, high resolution image. Ultimately, the LPD design translates into superior image quality (with no motion blur); near 180 degree viewing angle from above, below or side;  240hz refresh rate; high contrast; and a longer life than conventional displays.

Furthermore, because the phosphors constituting the video image are at the screen surface with minimal filtering, LPD is a bright –and highly efficient –emissive display.

Will LPD technology be an HD game-changer, as its proponents predicts? Given the technology’s potential for improving the quality, lowering the cost, and reducing the environmental impact of the large format displays, the market seems to ripe for its entry. However, not every technology that seems better has always performed well in the industry. Marketing efforts and educating consumers about one’s product has a lot bigger role to play in a successful launch than technical data sheets.

OLED lighting hits mainstream America

If you were earlier undecided about choosing between LED and CLF lighting, the market is about to add to your confusion as it starts flooding with the new OLED light systems.

Where LED (light-emitting diode) lighting uses small, intensely bright sources of light, which are typically made to look like traditional light bulbs, OLED (organic light-emitting diode) lighting uses flat, dimmer sources of light, essentially resulting in a glowing square or rectangle. Steady advances in manufacturing technology have made OLEDs bright and long-lived enough to use, and now they’re going mainstream: Acuity Brands whose $2 billion in annual sales make it the largest lighting company in North America, is now selling OLED light fixtures in Home Depot.

Because OLED panels are not piercingly bright, they can be mounted in fixtures seen directly by the eye; there’s no need for reflectors or diffusers to cut the glare. The approach also opens new options for lighting designs.

At Home Depot, Acuity is selling two fixtures, each in configurations that can be suspended or that can be mounted directly to a wall or ceiling. The $300 Chalina is like a four-petal flower, with four square OLED panels arranged around a central one. The Aedan uses two elongated panels facing opposite directions and costs $200. The company also offers a variety of OLED fixtures for commercial customers.

OLED is seen by many as a premium in comparison to conventional lighting, even LED. The technology itself is more sophisticated; however the only concern is its pricing. And OLED unit can cost about 50 percent more than an LED. If that suits your budget in exchange for superior quality and reduced electricity bills, then you might as well should add it to your holiday bucket.

LG forms its new OLED division

Even as LG is reported to be in forward motion to showcase its new Quantum Dot 4K UHD TV in CES 2015, LG Display, the display-panel making affiliate of LG Electronics has formed a new OLED division that will exclusively focus on commercializing its namesake technology.

The South Korean tech giant has been quite open about its ambition to maintain the lead in OLED TVs that it has and is not afraid of being left alone as the sole vendor of the technology. Samsung has already opted for QD LCD technology on its TVs for next year citing low demand for OLED units, which is primarily because of its high price tag.

Even with signs or rejection from many of LG’s competitors, the firm is expected to release more models of TVs with OLED displays in 2015 as well.

LG’s new division is said to be headed by the company’s CTO Yeo Sang-deog, who was recently promoted to president from executive vice president for his contribution in securing LG’s OLED leadership and expanding client base in TVs and mobile.

All OLED related projects are expected to come under the umbrella of the new division. A new department to manage OLED buying clients has also been formed.

The aim behind this move is reported to be the scattered developmental work within LG on OLED technology based products, especially when LG is set to quadruple OLED panel production this month in an effort to bring down the price of OLED TVs, making them a more attractive option to consumers. The company’s 55-inch OLED TV currently costs almost $2,800, an exceptionally high price for a TV unit.

The South Korean tech giant is also hard at work to minimize burn-in effects, one of the biggest detractors to the touted technology, in which some images are left stuck on the screen when on-screen for long stretches. According to LG, products that are already in the market do not have this issue and that it looks forward to solving the problem permanently in the future.

LG is all set to play it big at CES 2015 with Quantum Dot 4K display

LG electronics has emerged as the single most prominent firm in developing and implementing OLED in its TVs. However, despite the obvious dominance, the company is all set to venture deeper.

After successfully hedging its new OLED curved TVs in the market all throughout 2014, the company is now ready to raise the bar by reportedly aiming to introduce its new Quantum Dot 4K ultra high-definition (UHD) TV at the upcoming CES 2015 event in January next month.

The prime reason behind introducing the Quantum Dot display seems to be driven by the sky high prices of OLED TV units which can go upto $2500. A similar sized UHD TV will cost about half the price. And now with Quantum Dot technology, LG claims that the display is expected to be as sharp as OLED at a much lesser cost.
Another problem with OLED TVs which LG aims to resolve with Quantum Dot is their shorter life span in comparison to LCD – and televisions are not something the average consumer wants to upgrade more than once every 3 or 4 years at best.

 

Therefore, LG’s new Quantum Dot technology could prove to be a much more tempting alternative for many consumers. The ‘quantum dots’ are basically nano-crystals of varying sizes , which is usually between 2nm and 10nm, that possess quantum mechanical properties that allow them to emit different colors. In LCD displays, the quantum dots are placed between the panel and the LCD backlight, which results in an increased brightness and a much higher color reproduction rate.

 

LG will be displaying its first 4K Quantum Dot TVs at the CES show in Las Vegas from the 6th to the 9th of January 2015. It will also make for an interesting observation as the new technology could have a significant impact on the OLED market at large.
