Common problems

Q: Q:What’s the difference between glass-free 3D and the 3D with glasses?

A:

    It’s really inconvenient when you wear something on your nose, especially for those who wear glasses already.

    What’s more, no matter polarized light, shutter release or normal red-blue glasses, it’s unavoidable of screen brightness decline and difficult to watch details in darkness or under condition of low image contrast.

    Because it is impossible to completely eliminate the low frequency component of the modulation signal for shutter device way, people will feel the flashing which may lead to visual fatigue if watching for long time.

    Red-blue glass has impact on visual health because of the asymmetrical stimulation by different wavelength light.


Q: Q: What’s the suitable distance for watching?

A:

   Different products have their own watching distances according to different occasions: for pad, phone and other terminal devices, the best view distance is 30-50cm; and for advertisement player it is 2m-5m.

    We offer a best view distance for every series of product as well as certain tolerance ranges front and back. Far away from the best view distance may led to poor stereo effect and moirés.


Q: Q: Why we feel dizziness when watch the glass-free 3D contents?

A:

    This is related to 3D hardware design, process quality and contents displayed.

    People will see obvious ghosting and feel visual dizziness if the monitor has serious crosstalk.

    Some glass-free 3D monitor has narrow visual angle. If you were just in the “bad” area you might feel dizzy because of the improper space parallax.

    Also, the out screen level should be appropriate when processing the 3D contents. Otherwise the convergence effect of human eyes may cause wider convergent angles or inconsistency of parallax relations and other 3D psychological feeling relations. All these could lead to uncomfortable feelings.


Q: Q: How can I get the 3D content?

A:

    There are 3 ways to get 3D videos generally: modeling & rendering, transforming from2D and shooting.

We provide diversified solutions targeting at customers, cooperation suppliers and individual developers.

    There are many 2 view points stereo films and videos available in internet for download and most of them are left&right format. Besides, there are also special formats like up&bottom, red&blue which are compatible with our 3D player for local and online playing.

Beyond that, as VR industry is getting booming nowadays, there are so many VR contents emerging constantly, which also can be played on our player via certain transformation.

    Moreover, we have plug-ins for normal modeling software and development engines targeting at industries with 3D modeling objects, such as industry design, anime game etc. so that it will be convenient to make contents displayed on glass-free 3D monitors.

We also developed player with proprietary IP rights which could transform 2D resources to 3D and picture editor app (cutout, depth distraction) to meet different demands.

     In stereo shooting, we offer 2 view points and multi view points shooting schemes as well as single camera static target stereo video solution with low cost.
