3D Flat Panel With No Glasses

Posted by timothy on from the my-flat-panel-has-no-glasses dept.

m4c north writes "From Japan Today: 'Toshiba Corp said Friday it has developed a brand-new flat-display that allows viewers to see three-dimensional images without using special glasses. The display is expected to be applied to arcade games, virtual menus at restaurants and simulations of buildings and landscapes. The company said it aims to commercialize the display within two years.' JCN Network offers a few more details than Japan Today's rather short summary. And Toshiba's [toshiba.co.jp] press release has some simple figures. Maybe pinball will make a comeback!"

    Sharp has had 3D Displays that don't require glasses for some time now.

  2. Not the same as Sharp by eXzite · · Score: 5, Informative

    If you RTFA, it becomes evident that this display technology isn't the same as Sharp's 3D LCD. Sharp's display requires you to be in center of the display, and at a certain distance, and the 3D effect works by projecting steroscopic images at each eye. They direct two different screen images essentially, but it's still the same old trick, just without glasses, instead, a diffusion filter angles the output to each eye.

    From this article, it seems as if each pixel is a microlens that redirects the display to your two eyes on a per-lightwave basis. This obviously allows a much wider viewing angle, and for multiple viewers, while still creating the illusion of depth.

    Has anyone seen these screens in person?

    not these, but i've seen a model from these guys on a fair in helsinki in late 1999. i always thought it would be nice to have a 3d display that worked without glasses, and all of a sudden i found myself standing right in front of one. it was quite impressive, good image quality and yes, a convincing effect. only when i moved my head it took a very short moment to retrack my eyes and readjust the prisms (there are prisms in front of each vertical pixel row. they direct the light so that one eye sees the even and the other the odd numbered pixel columns). the guy peresenting it told me they had played quake III on it :)
    i came across their displays again on cebit a few years later, there also were some by the fraunhofer institute (the ones i've seen are probably not on the page, they had one or two that tracked your eyes and adjusted to your position, and one that only worked at a specific position, iirc).

    anyway, while searching for the seereal link above, i came across this list of 3d displays, there even are price quotes for a few.
