Mitsubishi Digital Electronics America Inc, a US subsidiary of Mitsubishi Electric Corp, demonstrated a 73-inch 3D display (one of the world's largest) at the pre-event press conference for the 2009 International CES.
The display will initially be intended for playing videogames. But Mitsubishi said, "We are expecting 3D Hollywood movies to be available on Blu-ray discs as 3D videos within 2009 and viewable on this display. We prepared 10 models in different screen sizes up to 73 inches and started selling them in North America."
The 3D LCD display is based on the "LCD shutter method," which requires dedicated liquid crystal glasses. With this method, the display shows 3D video by switching images for each of left and right eyes at high speeds.
On the other hand, the glasses alternately open and close the left and right liquid crystal at the timing of switching the video. As a result, the left eye only sees the video for the left eye, and the right eye only sees the video for the right eye. To synchronize the display and the glasses, an infrared transmitter and receiver are quipped in the display and the glasses, respectively.
The new 3D display was, in a sense, jointly developed by Mitsubishi and Nvidia Corp. In other words, Nvidia's graphics processing LSI (GPU) "GeForce" series product is used in the display. Nvidia also designed the dedicated glasses. Nvidia is planning to expand the use of its GPUs to this kind of areas.
Commenting on the display, Nvidia said, "Because of the display's high frame frequency of 120Hz, its image quality became much sharper than that of 60Hz 3D LCD displays." This is because, with the LCD shutter technology, the virtual frame frequency for each eye is half the original frame frequency.
