Epson's new smart glass "MOVERIO BT-300" with high image quality by adopting silicon OLED

Seiko Epson announced the "BT-300" for individuals, the "BT-350" for commercial models, and the "BT-2200" for commercial use as the third generation products of the smart glasses "MOVERIO". .. The BT-300 will go on sale from November 30th, with a direct sales price of 83,280 yen.

By adopting silicon OLED (organic EL), it is characterized by realizing high brightness, high concept, high resolution and high image quality as well as compactness and weight reduction, Mr. Atsuya Tsuda, General Manager of Seiko Epson HMD Business Promotion Department , "I was finally able to make a product that fits the concept I envisioned when I started the MOVERIO business. In terms of technological evolution, this evolution is better than the evolution from the first generation to the second generation. It's big. We can launch into new markets. "

MOVERIO released the first generation "BT-100" in 2011. In 2014, we introduced the second-generation "BT-200," which is 66% smaller. Furthermore, in 2015, it commercialized the "BT-2000" specialized for business use.

In addition to personal use such as video viewing, mainly for male users in their 30s and 40s, it is also being used for business purposes. It is also used for services such as providing tourist information by projecting the situation.

The 3rd generation MOVERIO released this time weighs 69g, which is about 20% lighter than the 2nd generation product, and has improved wearability by pursuing weight distribution. The shape of the vine on the mounting part has been revised to improve stability, and the use of magnesium contributes to weight reduction, robustness, and heat dissipation. It can now be worn comfortably even after long-term use. In addition, by using the included nose pad for eyeglasses, it can be easily worn even from the top of the eyeglasses, and the corresponding eyeglass width has expanded to about 147 mm, making it available to more people. That is.

In addition, the controller, which is the operation unit, has been revived from the cross key used in the first-generation products, and its operability has been improved by using it in combination with the trackpad.

The CPU is equipped with Intel's ATOM x5 processor. Android 5.1 is used as the OS, and it is said that the performance has been improved by 5 times. In addition, the built-in camera has been improved to 5 million pixels. Driving time is about 6 hours in video mode.

The biggest feature is that it uses Epson's original silicon OLED.

Previous products used an HTPS liquid crystal display, but by newly adopting a 0.43-inch ultra-compact high-definition color silicon OLED display, we are aware of the screen feeling (display frame) that could not be realized with the conventional model. In addition to enabling video expression that does not allow you to do so, it also enables realistic color reproduction with high brightness and high color gamut.

Uses silicon OLED

"The contrast ratio is 100,000: 1, which is a big evolution from the conventional 230: 1. Realistic field of view and see-through video and information by MOVERIO are displayed seamlessly, enabling integrated realistic AR (augmented reality) expression. I'm doing it. "

Silicon OLED uses a white light emitting element. A white light emitting element is resonated at different resonance frequencies by an optical resonator mounted in the cavity to emit red, blue, and green, respectively. This light is displayed through a color filter.

"Compared to the conventional structure, it is possible to widen the color gamut, improve efficiency, and miniaturize it, and it is possible to achieve a brightness of about 2,000 cd / m2. These structures have been patented as Epson's original technology. It is. "

Uses silicon OLED.The display module is also downsized, and the lens is also downsized.

By using a white light emitting element, it is said that the longevity, which has been a problem of organic EL, has been realized.

The problem is that production is difficult, but we utilize the organic EL production line installed at the company's Fujimi Plant. "The yield at the time of mass production is higher than expected, and the production issues have been solved," he said.

The adoption of silicon OLED has the effects of eliminating the need for the backlight required for conventional liquid crystal panels and reducing the area of ​​the drive board by incorporating a driver IC in the display. This has made it possible to reduce the size of the display module, and by enabling light distribution control that makes use of the structure of the OLED panel, the lens and light guide plate can also be made smaller, contributing to lighter weight and smaller size. It is said that there is.

"By utilizing the characteristics of OLED and our unique emission direction control technology, light can be concentrated on the first lens, which leads to the miniaturization of projection lenses."
