Zecotek Patented 3D Display Technology
Unlike systems based on “space-sharing” (see this link for more details on space-shared 3D), which must share pixels and therefore their native resolution among views, Zecotek’s system uses a proprietary “time-sequencing” technology combined with a patented dynamic system of multiple lenses. This results in a display with more than 90 views with full native (base) resolution in each perspective. It is this large number of views and the extremely narrow angle of each view, which give a complete freedom of position for the viewers within large viewing zones. Zecotek’s prototype offers now ~50° continuous viewing angle.

Zecotek’s “time-sequencing” (see this link for more details) approach also means that the HD resolution does not need to be divided between views. Each view has exactly the same HD resolution as the base screen one. This is because it is display time, as opposed to space (see Space-Sharing Auto-Stereoscopic Displays), that is shared. We therefore require a frame rate that is approximately 2,000 Hz for about 40 views which is readily available using existing and well known DLP back-projection elements.
Back-projection 2D monitors and TV’s have been available for many years and deliver high resolution, high quality images. Their only trade-off is that projection units have more physical depth in their form factor than flat panel displays. (This depth can also be significantly reduced to almost flat panel form factor with the use of special optics).

Zecotek’s 3D multiple-view auto-stereoscopic display with its “time-sequencing” approach can provide the most natural 3D experience, as it allows for a freedom of head movement similar to that required for seeing objects in the real world.

The marketing limitation of the DLP-based back-projection 3D TV for the consumer market is that of the form factor – DLP’s are not perceived as a flat panel (even though with optical modifications form factors can approach flat panel depths). While Zecotek’s technology is fully adaptable to flat panel configuration, this will require matching flat displays with frame rates exceeding 2,000 Hz. Such flat panel speeds are not yet available (as there has been no demand to date), however many industry players have these in development for other applications. With rapid advances in OLED’s (Organic Light Emitting Diodes) resulting in frame rates over 2,000 Hz, and as manufacturing costs of these panels go down, Zecotek’s patented technology will yield a flat panel configuration highly suitable for consumer markets well in advance of those using space sharing systems requiring greater pixel density, in particular as pixel density is directly related to production yield and, therefore, panel cost.
