NOVALUX 和 EPSON 公司于 2006年3月 13日 签署了关于“延伸空穴表面发射激光技术”(NECSEL™) 的开发和授权使用协议，
       根据这一协议，NOVALUX公司允许EPSON公司使用RGB三色激光参考设计和(NECSEL™) 半导体芯片。EPSON  公司计划使用该芯片结合自己的高精度处理器和多年积累的光学引擎技术发展该公司领先的3LCD投影。从而达到高品质投影效果和降低制造成本的目的。
       “我们很高兴能和EPSON 公司这样的领先世界的微显示制造商合作” NOVALUX公司主席和CEO  Jean-Michel Pelaprat说，“这是我们公司产品能成功进入显示器件市场很好证明，解决了该市场长期难以解决的光源问题。NECSEL 激光光源具有的高画质、长寿命、低价格特点正好适合于下一代投影设备，必将带来崭新的视觉感受”
       该交叉授权协议强调EPSON 公司向NOVALUX公司提供高温多晶硅temperature polysilicon (HTPS) 和 3LCD 投影技术.EPSON 公司自1994年以来一直是3LCD技术的领导厂商。
       EPSON 公司主席Seiji Hanaoka 说：“我们的3LCD技术一直以来因为优秀的亮度和画质得到市场的认可，我们将继续利用最新科技推进3LCD技术的发展。我们相信激光光源对Epson公司的 cutting-edge 投影技术来说是一个光源技术突破口，该技术能让我们以有竞争力的价格推出更优秀的设备。NECSEL技术是一个理想的光源技术，我们十分高兴能和NOVALUX公司合作把这个发明成果代给我们的客户”
        激光一直被认为是潜在的投影光源，因为激光有色彩饱和度高和能效高的特点。然而，一直以来，缺乏合适功率的激光（原文为have lacked the power），以及价格昂贵的原因一直未用于投影电视。NECSEL技术克服了这一障碍，使激光技术能够用于新一代投影。该协议的结果是市场上将出现一种具有无敌的亮度和对比度、逼真的色彩、长寿命、即开即关的投影，所有这些益处都能以低于市场现有产品的价格推出。
       Novalux公司的NECSEL技术能以革命性的火柴盒大小的设备上输出高功率的激光. 相对UHP灯泡来说，NECSEL色域大、结构简单、价格便宜。特别是用于3LCD系统时不再需要偏光器polarizers, 滤色镜color filters, 反光镜turning mirrors 和广角镜头fly’s eye lenses。另外还能带来长寿命、即开即关、低维护成本的好处。

NOVALUX AND EPSON JOIN FORCES TO DEVELOP NECSEL™ LIGHT SOURCES FOR CONSUMER DISPLAY PRODUCTS

SUNNYVALE, Calif., March 13, 2006 – Novalux, Inc., developer of Novalux Extended Cavity Surface Emitting Laser (NECSEL™) technology, announced today that it has entered into a joint development and license agreement with Seiko Epson Corporation (“Epson”) for NECSEL-based RGB illumination devices for use in microdisplay-based products such as projection TVs.

According to the agreement, Novalux licenses its RGB laser reference design and will supply Epson with the NECSEL semiconductor chips. Using the chips, Epson plans to leverage its high-precision processing and optical technologies and years of expertise to develop optical engines for integration into its market-leading 3LCD projectors. This development is expected to achieve high-quality, high-performance projection displays with lower production costs.

“We are delighted to enter into this agreement with Epson, one of the world’s leading microdisplay manufacturers,” said Jean-Michel Pelaprat, Novalux chairman and CEO. “It is a testament to the benefits that our technology brings to the display marketplace and a validation of our business model. It will allow solid-state light sources to infiltrate projection display, a market that has been severely limited by legacy lamp technology. NECSEL sources are higher performance, longer life and lower cost—they are perfectly suited for next-generation projection devices and will enable the best viewing experience to date.”

The joint development agreement also underscores Epson’s commitment to its high-temperature polysilicon (HTPS) and 3LCD projector business. Epson has been the leading manufacturer of HTPS panels, the main component in 3LCD projectors, since volume production began in 1994.

Epson President Seiji Hanaoka said, “While our 3LCD projection systems continue to gain marketplace recognition for their superior brightness and picture quality, we are further driving growth by perfecting these systems with the latest advanced technologies. We believe laser illumination is a breakthrough in lighting technology that – combined with Epson’s cutting-edge projection technologies – could allow us to provide enhanced device performance at a competitive price. NECSEL technology is ideal for this application and we are excited to work with Novalux to bring this innovation to our customers.”


Lasers have long been recognized for their potential as illumination sources for projection applications due to their saturated color output and high light energy efficiency. Historically, however, lasers have lacked the power, the small form factor and cost performance to realize laser-based projection TVs. NECSEL sources overcome these obstacles, making them an alternative light source for next-generation projectors. As a result of this agreement, future laser-based projection TVs could one day exhibit unmatched picture brightness and contrast, lifelike colors, long life operation, and responsive on/off—all from a lower cost system than can be produced today.

Novalux’s NECSEL sources produce high-power light output from a revolutionary package smaller than a matchbox. They provide an expanded color space and allow simplified, lower cost light engine architecture over UHP lamp-based systems. Specifically, when used in a 3LCD optical engine, NECSEL sources eliminate the need for polarizers, color filters, turning mirrors and fly’s eye lenses. Other advantages include long lifetime, instant-on and low étendue.

エプソン、プロジェクションTV用レーザー光源の開発へ
－Novaluxと共同開発。画質向上/ランプ交換不要に

3月13日発表


　セイコーエプソン株式会社は13日、米Novaluxと、プロジェクションテレビ用のレーザー光源モジュールを共同開発することで合意し、開発契約を締結したと発表した。高圧水銀ランプに代わる次世代の光源として飛躍的な高画質化や低コスト化を目指す。
　レーザー光は、単色性と指向性の良さから、広い色域と高い光利用効率が得られることは知られていたが、プロジェクションテレビに使用できるほど高出力かつ、小型、低コストな製品は存在しなかった。

　今回の共同開発では、エプソンが持つプロジェクションテレビ技術や精密加工技術と、NovaluxのNECSEL(面発光型レーザーアレイ技術)を融合させることで、従来比3倍の高出力を持った光源モジュールを開発するという。

　同モジュールを搭載することで、光利用効率が向上。明るく、高コントラストの映像が得られるほか、超高圧水銀ランプと比較して広い色再現領域も実現できるため、画質の向上が期待できるという。

　さらに、商品の耐用時間に対して実用上十分な寿命を有し、従来のようなランプ交換が不要になるとしている。ほかにも、光源の安定までに時間がかからず、瞬時に点灯したり、切断することも可能。

　また、光源に赤青緑の三原色が独立しているため、色分離のためのフィルタが不要になる。さらに、直線偏光を出射するので、偏光変換素子も不要となり、光学機構の簡易化もコスト削減につながるとしている。

所以我在等SONY的SXRD+激光光源技术的新款正投，VW100最大的缺点就是其灯泡寿命只有1000小时，真是买得起机子，买不起灯泡啊！

SONY要出激光光源的产品也只会用于：GxL上，应该不会率先在SXRD上采用。原理上来说，衍射成像的 GxL是最能发挥单色性最好和相干性最好的激光的优势的。将激光用于 GxL所带来的投影产品的画质飞跃要明显比反射的 SXRD、DLP、D-ILA等产品大！

其实现在的激光光源也处于样机可供货的阶段，真正实现大规模量产还是有一段距离滴。

其实民用的激光投影产品在：2002年的CEATEC JAPAN 2002上就已经开发成功。当时是SONY第一次以民用电子产品的形式展出可用于家庭影院的 GxL（那时还叫：GLV）原型机！

这是当年的介绍：http://imageye.info/news/2002/n0210/n0801.html

旁边的播放器还可以回放当时场馆中的说明概要！

至于在 2005年爱知世博会上所展示的 GxL产品和 CEATEC JAPAN 2002上展示的不太一样，爱知世博会上展示的是专业的数字影院使用的大型化的 GxL放映机（应该说，在民用产品上，SONY的 GxL推进实验室的进程速度比数字影院的专业化产品要快！毕竟类似于三菱的原型机在 2002年就已经做了公众展示！）

问题主要还是出在激光器的量产上，目前作为样机制造出一个甚至十几个出来都不是问题，但要商品化大批量制造却有难度！所以综合来看，真正的使用激光为光源的产品要到 2008年下一代投影技术中才会批量规模上市！

现在正投产品依然会是以：氙气、UHP、UHE、UHM  等光源为主！

NOVALUX TRIPLES OUTPUT POWER OF PROTOTYPE SOLID-STATE LIGHT SOURCES FOR CONSUMER DISPLAY PRODUCTS

Unique NECSEL™ Sources Will Be Featured In Demo Rear-Projection TV

SUNNYVALE, Calif., January X, 2006 – Novalux, Inc., developer of Novalux Extended Cavity Surface Emitting Laser (NECSEL™) technology, announced today that it has achieved 1.5W output power from its blue and green NECSEL solid-state lighting prototypes—three times the power of previous devices. Novalux will demonstrate these unique NECSEL light sources in a demo rear-projection TV during the 2006 International Consumer Electronics Show (CES) in Las Vegas, Nevada, January 5-8, 2006.

“Achieving 1.5-watt output from our green and blue NECSEL devices is a significant milestone in our product evolution,” said Greg Niven, vice president of marketing for Novalux. “Our ultimate goal is to produce three-watt light sources for integration into microdisplay-based devices such as home theater front projectors and rear-projection TVs. NECSEL technology significantly enhances display performance and enables simpler light engine architectures—it is reenergizing a marketplace that has been limited by legacy UHP lamp technology.”

Novalux will show its 1.5W NECSEL light sources in a prototype rear-projection TV during the 2006 CES. The TV demonstrates the expanded color gamut and simplified, lower cost light engine architecture that laser technology provides over conventional UHP lamp-based systems. The demo also offers a glimpse at the compact laser package that will be housed inside next-generation projection TVs and front projectors.

Novalux’s blue and green NECSEL devices produce 1.5W at 460 nm and 532 nm, respectively, and are housed in a revolutionary package smaller than a matchbox. All NECSEL light sources produce color-saturated output, allowing them to reach a larger color space than competitive lighting technologies. They are also wavelength selectable, so integrators can create multi-primary laser displays that include colors such as cyan. Moreover, NECSEL sources provide bright, speckle-free output, resulting in clear, vibrant images unattainable by any other lighting technology. Additional advantages include long lifetime, instant-on and low étendue.

WHAT IS NECSEL™ TECHNOLOGY?

NECSEL™ (Novalux Extended Cavity Surface Emitting Laser) is a revolutionary, patented, semiconductor laser technology platform based on high-power surface emitting diode lasers. NECSEL emitters produce diffraction-limited Gaussian beams of infrared (IR) light, which are easily frequency doubled to make visible wavelengths. Constructed with standard InGaAs semiconductor material, they can be manufactured with wafer-scale methods and known-good-die techniques. These unique characteristics make this the first solid-state laser technology to meet the performance and price demands of high-volume display applications.

Novalux manufactures NECSEL laser chips in our vertically integrated facility in Silicon Valley. This location includes a state-of-the-art 4-inch GaAs wafer fab that can produce several million laser array chips per year(公司在硅谷的工厂采用先进的4英寸GaAs 晶元制造NECSEL激光芯片，量产水平已能达到每年几百万片）. NECSEL lasers meet strict Telcordia reliability requirements with a mean time to failure of one million hours (20% drop in IR laser output). Second harmonic conversion efficiencies from NECSELs have exceeded 50% for intra-cavity conversion with a total of more than 100mW of average visible output from a single emitter. Moreover, unlike edge-emitting diodes that fail with high-peak-power operation, NECSEL lasers’ broad-area surface-emitting architecture ensures the power density at the output aperture remains well below the damage threshold.

NECSEL emitters are manufactured in a monolithic array format. This allows for low-cost power scaling, speckle-reduction, and redundancy (increased reliability through no single point failures).

AFFORDABLE
Our platform reduces light engine cost on several levels:


NECSEL light sources are more affordable than current pricing of UHP lamps.

Our sources enable simpler, smaller, less costly light engines. With DLP™ systems, our technology eliminates the need for a color wheel, light tunnel and relay optics. For 3LCD engines, we eliminate the polarizers, color filters, turning mirrors and fly eye lenses.

They enable less costly microdisplay panels. Our sources project all of their light onto even the smallest microdisplays without a reduction in coupling efficiency. Reducing microdisplay size reduces their cost.

Our low étendue sources emit at narrow angles, allowing simpler, more affordable projection optics.

翻译如下：

NECSEL 激光器通过以下途径降低投影（光学引擎）制造成本

1）价格比UHP光源价格低
2）能用于制造更小巧、更便宜、更可靠的光学引擎。
用于DLP技术的话，可以不需要色轮、导光通道和相关光机结构；
用于3LCD技术的话，可以不需要 polarizers偏光镜, color filter滤色镜s, turning mirrors 分光镜and fly eye lenses
3）能减少微显示设备的体积、减少制造成本
4）光发射角小，允许使用更简单、更便宜的光机结构
