Toshiba is set to become the first PC maker to put a 3D-capable Blu-ray Disc laptop on sale, it said Monday.

The company's Dynabook TX/98MBL will hit Japan in July and is based around a 3D system from graphics-chip maker NVidia.

NVidia's "3D Vision" system combines one of its GeForce graphics cards with a pair of active-shutter glasses, a plug-in transmitter to send sync signals to the glasses and software.

Active-shutter glasses flicker on and off 60 times per second in sync with the image being displayed on the screen. The screen shows 120 images per second with alternate frames for the right and left eye and the glasses help separate these and direct the relevant image to the correct eye. In this way the view gets an illusion of depth in the image.

Toshiba's laptop has a 15.6-inch display and a Blu-ray Disc drive with support for 3D movies. The laptop is based around an Intel Core i7-740QM processor and the GeForce chip in use is the GTS 365M, said Toshiba.

It will go on sale in July in Japan for about ¥250,000 (US$2,745). Toshiba plans to put it on sale overseas but isn't ready to announce launch plans.
