LCD Panels Display 3D Without Glasses

By integrating an advanced 3D film with small- and medium-size LCD displays that use optically compensated bend (OCB) mode, Toshiba Matsushita Display (TMD) Technology Co. Ltd. is able to present true 3D viewing at a glance, without the need for special glasses. The company is demonstrating the technology this week at CES 2009 in Las Vegas.

TMD’s OCB technology improves on conventional LCD technology by increasing response time and contrast ratio to achieve near CRT-like image quality. For the CES demonstration, the backlight modules of 3-in. and 9-in. LCD displays from TMD have been enhanced with 3D film. Through directional backlight technology, left and right eye images are focused sequentially into the viewer’s eyes, allowing for full resolution of the display panel. Only one panel and modified backlight are required. Backlight module assembly is easy. No precision registration is required.

In addition to eliminating the need for special glasses, the technology allows for extended comfortable viewing. The 3D film easily integrates into today’s thin, high-resolution displays, and enables simultaneous 2D and 3D viewing on all or parts of the display with no picture degradation. TMD plans to commercialize 3D displays within the next year.
