Epson Starts Volume Production of Ultra-Compact High-Resolution HTPS TFT Color Liquid Crystal Panel for Electronic Viewfinders

Epson Starts Volume Production of Ultra-Compact, High-Resolution HTPS TFT Color Liquid Crystal Panel for Electronic Viewfinders
– Optical viewfinder replacement enables smaller, thinner digital cameras –

Seiko Epson Corporation (“Epson”, TSE:6724) announced that it has begun volume production of a new high-temperature polysilicon (HTPS) TFT color panel for electronic viewfinders. Measuring just 0.47 of an inch (1.2 cm) diagonally, the new panels offer SVGA (800 x RGB x 600) resolution in red, green and blue for a total of 1.44 megapixels.
The new panels are targeted at camera manufacturers for use as electronic viewfinders in mid- to high-end digital single lens reflex (DSLR) cameras.

Competition in the digital camera market has reached a fever pitch. Companies are launching new products with higher resolutions and more features at even lower prices. In recent years, more and more consumers have been switching from compact cameras to SLR units in pursuit of better performance and image quality, driving the need for smaller and thinner DSLR cameras with video and other features.

Epson’s new panels meet this need and open a whole world of possibilities for DSLR cameras.

Until now, no electronic viewfinder has been able to offer the resolution and fidelity needed to replace optical viewfinders and to focus the image. Epson’s new panel, developed using HTPS technology, not only makes this possible but also uses an analog driver to recreate smooth gradations and a natural softness. This panel will allow camera manufacturers to eliminate the mirrors and pentaprisms needed for optical viewfinders, enabling much smaller and thinner camera bodies and letting users capture the image they see. In addition, the use of a color filter prevents the color breakup that tends to occur with other color systems when shooting fast-moving subjects and while panning.

Epson has long developed HTPS panels to meet the high-definition, high-resolution needs of its market-leading projector business. Using technology developed for projectors, Epson created this new product to meet the needs of the digital camera market.

This panel is the first in Epson’s new “ULTIMICRON” series of compact, high-resolution HTPS panels that display full color on a single screen for electronic viewfinders and other compact displays. Epson will continue to offer new solutions for the growing DSLR camera market by expanding its lineup with higher resolutions, better image quality, and smaller sizes.

Epson Toyocom Develops Ultra-Accurate, High-Stability TCXO

Epson Toyocom Develops Ultra-Accurate, High-Stability TCXO
New TG-5500CA provides OCXO-class frequency/temperature coefficient

Epson Toyocom Corporation, the leader in crystal devices, today announced the development of a highly accurate new TCXO (temperature-compensated crystal oscillator) that has an OCXO-class frequency/temperature coefficient of ±0.1 x 10-6, enabling power and space saving in network equipment.

Samples of the new TG-5500CA oscillator will become available in December 2009. Commercial development is scheduled for March 2010.

Reference clocks used in ultra-compact cellular base stations for home and office use require high accuracy, with a frequency/temperature coefficient of ±0.1 x 10-6 or better. Core network equipment, meanwhile, requires stability of ±4.6 x 10-6 over a period of 20 years. Obtaining this class of frequency tolerance/stability normally requires the use of a highly stable oscillator in the OCXO (oven-controlled crystal oscillator) or atomic oscillator classes.

The TG-5500CA, in addition to being equipped with a QMEMS*1 crystal unit, has an original structural design that takes into account thermal conductivity and that stabilizes the frequency/temperature coefficient and long-term ageing characteristics.
Frequency-stability characteristics that affect the quality of transmissions, such as temperature tracking*2.and frequency fluctuation*3, have also been dramatically improved compared to Epson Toyocom’s conventional 7.0 x 5.0 mm TCXO (Figure 2).

The improvement enabled frequency tolerance/stability that is one rank above that of current TCXOs. The TG-5500CA can thus be used in applications that were formerly reserved for OCXO-range devices. Using a TCXO instead of an OCXO can significantly help reduce the power consumption and size of systems. The TG-5500CA can also be used to improve the performance and function of systems that employ an existing TCXO, but it is exceptionally well-suited for use in core network equipment, such as femtocell*4 base stations and Stratum 3*5 products.

Main features
1.Ultra-high stability, with a frequency/temperature coefficient of ±0.1 x 10-6
2.Excellent hysteresis characteristics
3.Long-term frequency ageing characteristics (±3.0 x 10-6 over 20 years) meet Stratum 3 requirements
4.Good temperature tracking and minimal frequency fluctuation

Seiko Epson Begings Volume Production of New HTPS Panels Employing C2 Fine Inorganic Alignment Technology for 3LCD Data Projection

planar_projectorSeiko Epson Corporation (Epson) has begun volume production of two models of high-temperature polysilicon (HTPS) TFT liquid crystal panels employing C2 Fine technology, a 0.74-inch (1.9 cm diagonal) model and a 0.8-inch (2.0 cm diagonal)model, designed for 3LCD-type data projectors. The new panels utilize D7 process technology to achieve higher aperture ratios, making possible increased brightness, and also employ C2 Fine inorganic alignment technology that produces even greater contrast and higher image quality.

As the practice of making presentations at companies is now mainstream, in addition to other factors such as the growing trend of using IT in the education market, the data projector market is expected to continue to expand. The growth in the variety of uses of data projectors has led to demands for higher resolution and wider displays, as well as for greater brightness. Furthermore, now that the projection of video images is increasingly being carried out in both business and educational settings, the demand has become greater for products capable of achieving higher image quality and higher contrast.

In order to respond to these market demands, Epson has been continuously engaged in the commercialization of panels with ever higher aperture ratios using its own original high aperture process technology called the D series. For home projectors, which require higher contrast and smoother images, continuous efforts are being undertaken to improve the panels by employing C2 Fine technology. By combining these technologies to further enhance the performance, these new panels are able to meet the demands arising from the diversifying uses of projectors.

Features of the new panels

Increased brightness by employing D7 process technology

* Products using 0.74-inch panel: approx. 4000lm
* Products using 0.8-inch panel: approx. 5000lm

Effect of using C2 Fine technology

1. Use of vertical alignment technology achieves products capable of high contrast
2. Use of inorganic alignment layer reduces orientation unevenness and produces smooth images
3. Use of normally-black mode and vertical alignment technology enables reproduction of jet-black

Epson Toyocom Announces The Development Of The World's Smallest Low-Current Real-Time Clock Modules

Epson Toyocom Corporation’s U.S.-based Timing Products Division has announced the development of the world’s smallest* real-time clock modules. The maximum dimensions of the new RTC modules, known as the RX-4571BD and RX-8571BD, are just 3.4 mm x 1.7 mm x 1.0t mm.

With a footprint and cubic volume that are 43% and 52% smaller, respectively, than those of conventional real-time clock modules in an LC package, the new real-time clock modules will help electronic equipment manufacturers further downsize their products while boosting performance. Samples of the new RX-8571BD will be available in April 2009.

Size comparison between the newly developed RX-4571BD/RX-8571BD and the conventional RX-4571LC/RX-8571BD

epsons-clock-modulesIn recent years, all manner of electronic equipment, from compact portable devices such as digital cameras and personal healthcare products to office and factory automation equipment, have seen explosive growth in functions, features and performance, coupled with lower power budgets. Not coincidentally, there is strong — and growing — market demand for thin, space-saving, low-power components. To meet this demand, Epson Toyocom has developed and is on target to commercializing the RX-4571BD and RX-8571BD real-time clock modules, which are in high demand for time and date data management applications.

The RX-4571BD supports a 3-wire serial interface, while the RX-8571BD is I2C-Bus(*1) interface compliant. The RX-4571BD and RX-8571BD, equipped with an ultra-compact QMEMS(*2) crystal chip, are the world’s smallest real-time clock modules with built-in crystal units. Epson Toyocom was able to diminish the size of these modules by using a new structure that applies Epson Toyocom’s original NPO (New Platform Oscillator) structure(*3), wherein a crystal unit in a ceramic package is sealed together with an oscillation circuit in a molded plastic housing. Combining a compact crystal unit with a real-time clock IC, rather than providing them separately, significantly shrinks the module’s real estate requirements.

With a crystal unit built into an ultra-compact package along with clock and calendar circuitry that operates at low voltage, the modules provide and manage the clock and calendar data for electronic devices at low power. In Standby, the RX-4571BD consumes 0.32 µA of current, while the RX-8571BD consumes just 0.22 µA (at 3 V, respectively).

The RX-4571BD and RX-8571BD help customers add value to their systems by using space more efficiently in feature-rich electronic equipment and by helping extend the time their equipment can run on a battery or charge. The modules will also pay dividends in the form of greater system reliability and quality, since the crystal unit’s characteristics are assured prior to shipment, alleviating the need for customers to design oscillation circuits or adjust output frequencies.

Epson Toyocom Introduces TCXO for High-Precision GPS Applications

Epson Toyocom Introduces TCXO for High-Precision GPS Applications

tcxo1

Epson Toyocom Corporation (“Epson Toyocom”), the leader in crystal devices, has announced the development of a new frequency-stable TCXO (temperature-compensated crystal oscillator) with frequency stability high enough for demanding GPS applications. The new TG-5025BA oscillator is housed in a 2016-sized package, the world’s smallest package category (actual dimensions are 2.1 x 1.7mm). Commercial development is scheduled for February, 2009.

The market for GPS capability in mobile terminals has been expanding in recent years. In particular, the percentage of cell phones with built-in GPS functions is rising globally due to applications that allow their location to be pinpointed in the event of an emergency call. The expansion of the market for personal navigation devices (PND) and other navigation systems is also driving demand for frequency-stable TCXOs, which are essential for accurate positioning. Mobile GPS devices such as these will be packing more features in increasingly dense assemblies and this trend is expected to drive market demand for high-stability TCXOs, especially small units.

Epson Toyocom is already setting the pace in GPS market trends with the TG-5005CG, a TCXO equipped with a photo AT chip. However, while the TG-5005CG offers high stability (0.5 x 10-6) in a 2.5 x 2.0 mm package, the market is already looking toward even smaller sizes. Epson Toyocom is on target to meet the more stringent size requirements with the commercial development of the TG-5025BA, a 2016-class TCXO that offers outstanding frequency stability.

The TG-5025BA is equipped with a photo AT chip, a very small, crystal chip microfabricated using Epson Toyocom’s unique QMEMS*1 technology. In addition to minimal variability of characteristics, the new oscillator promises high reliability thanks to the use of internal wire bonding and Epson Toyocom’s original NPO (New Platform Oscillator) structure*2. In the NPO structure the crystal unit, encased in a ceramic package, is sealed together with an oscillation circuit in a molded plastic housing. This structure reduces the susceptibility of frequency to changes in ambient temperature. Epson Toyocom’s IC design technology brings additional advantages to the TG-5025BA, including precise temperature compensation, low power consumption since driving is performed at voltages as low as 1.68 V, and a wide output frequency range (13 to 52 MHz).

Epson Toyocom has successfully combined all the essential technologies for the development and manufacture of crystal devices: superior crystal chip processing, packaging and circuit design technologies. The result is a small, stable, GPS-ready TCXO. The TG-5025BA boasts a 36% smaller footprint and a 43% smaller cubic volume than its predecessor (2520 TCXO product). Despite its size, however, it has a frequency-temperature coefficient (an indicator of frequency stability over a temperature range) of 0.5 x 10-6, a rating equivalent to that of a TCXO in a conventional package size. To top it all off, the TG-5025BA is stingy when it comes to power consumption, using some 30% less power than its predecessor.

Epson Toyocom plans to continue to beef up its line of ultra-miniature 2016 TCXO products and develop even smaller high-stability TCXOs to meet the burgeoning demand in the GPS market, where end-products sizes are shrinking as packaging densities increase.
