Development of 16:3-aspect, 19.2-inch Color TFT LCD Module by Mitsubishi Electric
Mitsubishi Electric made an announcement on development of 19.2-inch TFT-LCD module with 16:3-aspect, designed to enable a broad range of display and design solution for wider-format module such as kiosk display, information monitors, gaming and other entertainment applications. The new model, AA192AA01 comes in a form factor of 496.5mm (W) x 109.2mm (H) for the display of 16:3 ratio images (1920 x 360) pixels. Furthermore, the incorporation of white LEDs has allowed the newly developed module to achieve a minimum backlight lifespan of 60,000 hours at the room temperature (25 degrees Celsius). Read more
Development of Industry’s First 0.9V Drive MOSFETs for Mobile Devices by ROHM
Rohm made an announcement on development of industry’s first 0.9V type MOSFETs as part of expanding company’s ECOMOS series of low voltage drive. The newly developed drive is targeted for mobile devices such as portable audio, IC recorders, electronic dictionaries, portable radios as well as electronic toys to name a few. Rohm through development of this MOSFET has succeeded to control current leakage by optimizing the MOSFET gate layer and the channel profile making the 0.9V drive with a stable OFF state, enabling operation using only a single dry-cell (1.2V, termination voltage 0.9V) without requiring a step-up circuit, resulting in smaller, lighter sets with fewer external parts.

Development of Diamond based LED with Improved Output Power for Sterilization of Viruses by AIST
With increase in epidemic diseases caused by viruses such as H1N1 at a global level sterilization is becoming a critical necessity for society in their daily life. Up to now, sterilization has been carried out using heat, chemicals and UV light, where UV light posses many advantages such as being effective against thermotolerent bacteria, while not having any adverse chemical effects, and at the same time it directly acts on the bacterial DNA to inhibit the viruses proliferation. In this case, light with wavelength of around 260nm at which DNA absorbs light is capable of significantly sterilizing bacterial. Currently, mercury lamps that emits 254 nm UV light are being used to fulfill this task, however use of mercury in these lamps make them environmentally unfriendly, leaving researchers and manufacturers alike to develop semiconductor LEDs in achieving this task. So far, the development of UV LEDs has been focused in using LEDs that are composed of widely used gallium nitride, but the use of this material will make it difficult to fabricate LEDs capable of emitting light of shorter wavelengths. For this reason LEDs that emit light of wavelength 350 nm or shorter are not available commercially. Read more
Development of 2-Wavelength Laser Diodes with Significantly Lower Operating Current by ROHM
Laser guides are typically come in to types, one is the Loss Guides and the other is Real Index Guides. In spite of being simple and inexpensive, the Loss Guides have a tendency to absorb light within the device during laser oscillation besides showing unstable at high temperatures. On the other hand, Real Index Guides provide a stable operation with no light absorption, but their manufacturing process is complex and the production cost is high, limiting them to be only utilized as high output lasers. In response to this limitation, Rohm has succeeded in developing a highly reliable 2-wavelength laser targeted for low output applications such as DVD/CD playback by using an optimized, highly efficient Real Index Guide with no light absorption loss.

Development of RGB Laser Light Source Module for Large Screen Projectors by SONY
Sony just made an announcement on development of RGB laser light source module which is ideal for large screen projectors like digital cinema projectors. The newly developed RGB laser module features a high power laser of the three primary colors namely Red, Green and Blue with a combined output power of 21W, equivalent to 5,000 lumens, all in a single package measuring just 530cc, making it among the industry’s smallest. The new RGB laser module utilizes semiconductor diodes for the red and blue lasers plus a compact, high power solid-sate SHG (Second Harmonic Generation) laser for the green developed internally by Sony. The three lasers produced output power of 10W, 6W and 5W for red, green and blue respectively, resulting in a total output power of 21W. The energy conversion ratios of the lasers range from 15 to 22% (18% on average) a high efficiency for power visible lasers. Read more
Development of Low Power, Low Noise All-Digital Phase Lock Loop LSI by NEC
As demand for short distance radio communication for such systems as remote controllers, alarm systems and automatic meter reading is on the rise, one major concern that has preoccupied manufacturers of these systems is their power consumption, requiring these systems to have a longer battery life. At the same time, small and lightweight criteria for wireless devices imposed by the market demand forcing manufacturer to further reduce the battery, however, reduced battery size will translate to reduced total available energy. For such battery driven devices one way to extend the battery life is through intermittent operation through use of all digital PLL (Phase Lock Loop) offering a quick operations as well as their advantage in eliminating large on-chip passive filters. In comparison analog-based PLL does not constitute a good solution due to their long start-up time. Based on this requirement, NEC and NED Electronics developed a low-power low-noise all-digital phase lock loop (ADPLL) LSI targeted to be employed in midget wireless equipment yielding a long operation lifetime for small sized batteries.
