QD laser, retinal projection device "RETISSA Display II" with improved resolution and lower price

QD Laser has started accepting orders for the monocular head-mounted display "RETISSA Display II" that projects images directly onto the retina at the ASCII store. Scheduled to be released in February 2008, the price is 248,000 yen.

A head-mounted display for monoculars equipped with "VISIRIUM technology" that scans on the retina and projects images using a weak RGB laser beam and a high-speed vibration device (MEMS mirror). The model released in 2018 (598,000 yen) has been improved to reduce the price.

Since the retina is directly irradiated with a laser, it is characterized by being able to enjoy movies and other content in a focus-free manner, regardless of visual acuity problems such as myopia, hyperopia, astigmatism, and presbyopia, and the focus position.

The projector unit can be removed from the frame, and if the image is inverted with a switch, it can be used with either the right eye or the left eye. The removal mechanism makes it easier to binocular and mount on prototypes.

The new model has improved resolution. By tuning the beam quality on the retina, it has become possible to read up to about half the font size compared to the previous generation. The aspect ratio of the projected image is 16: 9, the angle of view is 26 degrees, and the number of effective display pixels is equivalent to 720p. Color reproducibility is 256 gradations.

The controller BOX is equipped with an HDMI input. HDMI supports 1080 / 60p, 720 / 60p, 480 / 60p signals, and can be connected to AV devices and mobile devices to display various contents. It also supports power supply to stick-type devices using the USB Type A terminal.

The controller BOX has a built-in 3,880mAh battery. It can be driven for up to 3.3 hours even outdoors without AC power. The charging time is about 3.8 hours, and the charging port is USB microB. The cable length connecting the projector and the controller box is 0.9m and cannot be removed.

The external dimensions excluding protrusions are 65 x 83.5 x 20 mm (width x depth x height) for eyewear and 74 x 150 x 29.25 mm (same as above) for the controller box. The weight of eyewear is about 40g (excluding cables) and about 260g. AC adapter is attached.
