The projector has a volume of just 410 cm3, its top surface area is equivalent to that of two business cards and it is shorter than a standard ball pen.
Sony's projector uses an alternative approach known as 3LCD, which, as the name suggests, uses 3 transmissive LCD screens, one for each color. Red, green and blue light passing through the screens creates 3 images which are combined in a prism before being projected.
The power consumption required for the LED unit and the entire projector is 20 W and 30 W, respectively. A wide color gamut of 120% NTSC can be achieved.
Also, Sony has developed a proprietary screen that can reduce the reflection of external light, resulting in extremely high screen luminance.

Unaxis Optics, which develops coatings technologies for optical components primarily used in projection displays, has acquired a stake in California-based Novalux, which manufactures high-power lasers. The Unaxis investment was part of a series B financing round which raised $21.7 million for Novalux.
According to the agreement, Novalux will license its RGB laser reference design to Unaxis, as well as supplying NECSEL (Novalux Extended Cavity Surface Emitting Laser) chips. Unaxis will then mass produce RGB laser modules and distribute them into the projection display supply chain.
Lasers such as the NECSEL are being promoted as alternatives to LEDs as replacement light sources in the rear-projection TV and other markets.
