What is "glasstron"

The Glasstron by Sony, mounted on a clear mannequin head.

The Sony Glasstron was a portable head-mounted display. The products included two LCD screens and two earphones for video and audio respectively.

The Glasstron was released to the U.S. market in 1997.

Various models were released. Supported video inputs included PC (15 pin, VGA interface), Composite and S-Video. A brief list of the models follows:

• PLM-A35: The most basic model with opaque lenses and no SVGA input.
• PLM-A55: This model had a mechanical shutter to allow the display to become see through, without SVGA.
• PLM-100: This model had a mechanical shutter to allow the display to become see through, with SVGA, somewhat unstable.
• PLM-S700: The S700 allowed for see through mode using LCD shutters and had support for SVGA output.
• PLM-S700E was the final model and used some of the world's most advanced components at the time. Its LCD had over 1.5 million pixels on a component the size of a ten-cent coin at SVGA (800×600) display resolution.

These products are no longer manufactured nor supported by Sony. The PlayStation VR can be considered in a way the successor to Glasstron.
