PicoP Display Engine - How it Works
Microvision’s PicoP display engine is used in Pico Projectors Displays, Vehicle Displays, and Wearable Displays. The PicoP display engine is comprised of a MEMS scanner, Red, Green and Blue Laser Light Sources, Optics, and Electronics. The PicoP display engine includes the drive electronics that acquire and process signals from a data source to control and synchronize the color mix and placement of individual pixels.
Each color pixel is generated by combining modulated red, green and blue laser light sources. The intensity of each of the light sources is varied to generate a complete palette of colors and shades. For example, red pixels require the red laser be turned on whereas the blue and green lasers are turned off. For purple pixels, red and blue lasers are turned on whereas the green laser is turned off.
The MEMS scanning mirror directs the beam of light toward the projection surface in the pico projector case. For other applications unique optical elements direct the beam of light toward the additional optics external to the PicoP display engine. For example, in the case of a head-up display there are external optics that ensure the image is viewable within the driver’s eyebox.
In the case of a wearable displays there are additional optics that are embedded into fashionable or protective eyeglasses. The pixels are arranged by a repetitive horizontal scanner motion that rapidly sweeps the light beam to place the pixels into rows and a vertical scanner motion that moves the light beam up and down to points where successive rows of pixels are drawn. This process is continued until an entire field of rows has been placed and a full image appears to the user.
The image is projected to the users eye, wall, or any other surface.
Since the PicoP display engine uses a single beam of light and a small scanning mirror to create an image, we can create a large image from a small package.

Benefits of Lasers in Real World Applications
Laser technology helps save lives, map the human genome, and accurately measure the distance between the earth and the moon.
Lasers have evolved from modern marvels to a staple of modern life with laser based levels and laser pointers becoming commonplace.
The benefits of laser technology are well known and widely used. Lasers produce a beam of light that is monochromatic, coherent, small and straight. More simply put, lasers generate a single color or wavelength. Most common laser based products use a small laser that emits red light. This works well for many applications like laser levels, bar code scanners, and conventional DVD players.
It is laser technology that has made possible jumps in storage capacity from vinyl to CD to currently available DVDs. CD’s introduced digital music and video reproduction to replace noisy, fragile and low capacity analog recordings. Developments in laser technology will continue to enable leaps in storage capacity. Recent announcements reveal that to make next generation DVDs hold even more data, manufacturers use a shorter wavelength provided by a blue laser.
NEW LASERS LEAD TO NEW OPPORTUNITIES
Laser technology also offers advantages for generating images. Lasers are smaller and brighter than alternative light sources. Light from most sources spreads out as it travels so that much less of it hits a given area as it moves farther from its source. Laser light doesn’t behave this way. The beam can be directed or scanned with precision and can even be “pixel” sized.
Three primary colors, (red, green, blue) are used to generate the full-color images we commonly see in televisions, computers, and video displays. Red lasers are established and widely available in commercial products today; blue and green lasers are coming shortly. Developments in these compact blue and green lasers will enable a new generation of products capable of generating full color images.
Laser technology can generate bright full color images from a battery powered micro-sized device. This is why Microvision chose laser light sources for the ultra-miniature PicoP™ display engine.
The PicoP enables manufacturers of hand-held devices to create next generation products that provide consumers with the ability to project full color, high resolution images from their mobile phones, laptop computers, personal media players, and other portable devices.

Low-light CCD imaging system
Low-light CCD imaging system
E2V’s L3M216 low-light CCD imaging system is designed for airborne and ground-based surveillance, underwater imaging with an enhanced blue response, driver view enhancement, commander’s night-sight and scientific imaging.The sensor allows use with small optical components and, since it is back-thinned, performance is similar to existing, while an improved CCD manufacturing process reduces horizontal smear. With 768 pixels/line, it has an onscreen display for manual control/monitoring, fanless cooling, analog and digital outputs and a 12 V d.c. supply. The system is designed so that the imaging section may be separated from the drive electronics by 150 mm, thus simplifying installation in tightly packed environments.Camera configuration can be modified either via the serial control path or via a membrane switch pad on the rear panel, in conjunction with a menu driven on-screen display. The camera displays current operating parameters such as video peak, video trough, exposure interval, EMCCD gain indicator, binning, filter and histogram processing status.The ALC setup allows qualified users to determine at what illumination levels binning, filtering, dynamic gamma, picture stretch and extended integration will be introduced. Image processing software calculates a focus index for a block of pixels in the centre of the array and presents this number on the display. The user simply adjusts focus to obtain a maximum value.For more information contact AfriMeasure, +27 (0)11 675 4447.

Active pixel CMOS flat panel array
Active pixel CMOS flat panel array
Hamamatsu recently introduced a large area flat panel CMOS sensor for X-ray imaging applications. The C9728DK is a new active pixel CMOS image sensor in which each separate megapixel in 1056x1056 image format has an individual amplifier, providing extremely low noise readout, with the noise being at least six times lower than existing conventional passive type CMOS flat panel sensors. Utilising a correlated double sampling (CDS) circuit and a direct deposition (DD) columnar structure CsI scintillator, the C9728DK creates high quality true 14-bit digital video signals. The specific DD CsI scintillator construction eliminates focusing lenses and tapered fibre-optics associated with the use of CCD sensors, which can cause image distortion and peeling problems in the field.The new sensor is also suitable for X-ray diffraction pattern imaging and other scientific X-ray imaging requiring very low noise with realtime image quality. The unit comes with USB2.0 interface for ease of operation and demonstration software with code and library for USB2.0 is supplied with the sensor.

OLED driver for small displays
OLED driver for small displays
11 June 2008
Texas Instruments has introduced an organic light emitting diode (OLED) power driver designed to enhance image quality for small form factor displays up to 2,5 inches. The TPS65136 power IC supports active matrix OLED (AMOLED) displays used in mobile phones, digital cameras and portable media players.AMOLED displays allow each pixel to emit its own light, resulting in high colour saturation, thin form factor, high contrast ratio, fast response time and low power consumption. The TPS65136 manages power to AMOLED displays by providing positive and negative voltages, and supplying less current and lower voltages than passive matrix displays. With just one 2,2 μH inductor to generate both outputs on the single-inductor, multiple-output converter technology, the device provides high picture quality and achieves a small solution size with a low component count. A buck-boost topology allows the device to generate a positive voltage up to 4,6 V and adjustable negative output voltage down to -7 V. In addition, the input voltage can be above or below the positive output voltage, allowing it to support new batteries with a starting voltage up to 4,8 V.The unique converter technology results in excellent line and load regulation, which is required to avoid potential display disturbances in mobile devices during transmit periods. The converter also lowers the switching frequency as the load current decreases, to maintain high efficiency over the entire load current range. The TPS65136 maintains the switching frequency above the audible range with a voltage-controlled oscillator to avoid causing audible noise from the vibration of the ceramic output capacitors.

electronica 2008 to showcase lighting technologies
electronica 2008 to showcase lighting technologies
11 June 2008
2007 marked a turning point in the worldwide display market, in that more liquid-crystal displays (LCDs) were sold than traditional tube TV sets. The market research institute DisplaySearch estimates that by 2015 around 90% of all display elements sold will be LCDs. Forecasts such as these are encouraging and inspiring an entire industry because modern flat-screen TV and computer screens, as well as the displays of mobile devices such as notebooks, cellphones and MP3 players, require background illumination which is provided by LEDs or organic LEDs (OLEDs). Market research institute iSuppli has forecast that the current LED market volume in this application alone will increase from $6 billion to $12,3 billion by 2012.However, background illumination is not the only driving-force behind the OLED market. Rapidly coming to the fore are new, environmentally-friendly, energy-efficient, reliable and colour-flexible signalling, lighting and illumination concepts in industry, through to applications in housing and building engineering, as well as the increasing number of OLED applications in modern cars.The technological trends for displays and OLEDs and their power supply will be highlighted at electronica 2008, a leading international trade fair for electronic components, systems and applications, which will be held in Munich from 11 to 14 November this year.The display boom is creating, in particular, demand for high-brightness (HB) LEDs. iSuppli estimates that the market for HB-LEDs was worth $3,7 billion in 2006 and expects it to double in volume to more than $7 billion by 2010. This in turn is fuelling demand for HB LED driver products with which several LEDs can be controlled simultaneously or very high light efficiency is possible. Strategies Unlimited is anticipating that this market - worth $865 million in 2006 - will increase to $1,9 billion by 2011. The beneficiaries of this boom are exhibiting companies such as Texas Instruments, with LED drivers for controlling high-resolution video display screens, and National Semiconductor, with high-current LED flash drivers or special online LED development tools which can reduce designs of LED power management solutions from weeks to minutes. A large number of technology leaders will also present their solutions at electronica 2008, for example Linear Technology with an integrated BIAS and white light LED voltage transformer solution for small to medium-sized TFT (thin-film transistor) LCD panels and STMicroelectronics, whose product range includes constant current LED drivers with an automatic energy-saving function.LEDs are also making inexorable advances in the automobile industry. They are used as efficient and anti-dazzle background illumination for dashboards and, as brake lights, replace conventional white light bulbs, as well as halogen and xenon lamps. Market researchers such as IMS Research estimated worldwide sales of LEDs in the automobile industry at $650 million in 2006; this is expected to double to $1,3 billion by 2016. The demand due to prescribed daytime driving lights in an increasing number of countries will lead to a growth explosion with LEDs in this sector from $5 million in 2007 to over $100 million in 2013. This will also benefit Osram Opto Semiconductors, one of the leading companies in the industry and an exhibitor at electronica 2008. The company's LEDs are already used, for example, as full headlights in a new SUV from Cadillac.Companies such as Optrex also provide a 'clearer view' behind the steering wheel. Optrex's transparent signage displays are based on OLEDs which are integrated in the windscreen and conveniently supply information and warnings. Their high efficiency, wide range of colours and now also their increasing durability are making versatile OLEDs attractive for more and more applications, ranging from a brightly coloured iPhone display through to the new 11-inch Sony OLED television. OLEDs are also becoming more important as regards illumination: Osram has already achieved a service life of more than 5000 hours for warm white OLEDs with a brightness of 1000 cd/m². Luminous tiles, LED wallpaper and luminous partitions therefore no longer seem far-fetched ideas.Visitors to electronica 2008 will be able to obtain a clear impression of the numerous advantages and application areas of OLEDs on the large number of exhibition stands. New stand concepts will be formulated up to November 2008 in which lighting no longer comes from excessively heat-generating light bulbs, but from power-saving, energy-efficient LED light sources.

Enabling inexpensive disposable LED lasers
Enabling inexpensive disposable LED lasers
11 June 2008
Information from Frost & Sullivan Technical Insights
Lasers are used in numerous applications, ranging from cutting sheet metal to detecting chemicals to facilitating ultra high-speed communication. Though there are various types of lasers, each with specific power outputs and features, none are considered inexpensive. In spite of their inherent benefits, lasers are still limited to those applications that can afford the technology which, depending on the requirements, could be quite expensive. Another hurdle facing laser adoption in the lower segments is the fact that most lasers require another laser to power them in order to reach their lasing potential. Now, researchers from the <>University of St Andrews have successfully developed and demonstrated what could possibly be the most inexpensive laser technology. Their lasers have the ability to be powered by conventional light-emitting diodes (LEDs) as opposed to more expensive pumping lasers and this could open up new potential markets in cost sensitive applications. The LED driven laser would be ideally suited to portable medical treatment, light-emitting clothing and so on. As their approach does away with the additional driving laser and replaces it with low-cost LEDs, the overall laser can be made quite compact and at a fraction of the original cost of existing technologies. This advancement was achieved through the joint efforts of Ifor Samuel and Graham Turnbull during their work on remarkable plastic-like semiconducting materials. The flexible light-emitting materials possess the characteristics of semiconductors while requiring only a simple manufacturing process like that of plastics. They have thus far been successfully used to make light-emitting sticking plaster for the treatment of skin cancer. This and other applications of such lasers could revolutionise point of care diagnosis and treatment. The elimination of the primary pumping laser and subsequent replacement with simple LEDs along with the plastic laser itself could lead to a new range of extremely low-cost lasers. The plastic laser efficiently converts visible light from off-the-shelf LEDs (such as those found in torches and traffic lights) into laser light. As the LEDs can be battery powered, the hybrid LED-laser approach can make for very simple and portable low-cost compact emitters. Another feature of the technology is that it can produce a variety of colours, making these lasers a suitable choice for applications such as spectroscopy or chemical sensing. The LED-laser is capable of producing a laser beam of any colour thanks to the fact that LEDs can be designed for any colour output. As the LED-lasers are inexpensive to develop, they can also be used for single-use medical diagnostic kits or in extreme environments such as sensing for explosives. According to Graham Turnbull, the LED-laser would cost less than $10, which is significantly less than most visible lasers, which can cost up to tens of thousands of dollars.For more information contact Patrick Cairns, Frost & Sullivan, +27 (0)21 680 3274, patrick.cairns@frost.com
