3 D Display Technology • Seeing in Depth – Not only X and Y axis, but also Z – Stereoscopic Image • Technologies – Eyeglassless

Spatial Division • Head Mounted Displays (HMD) – http: //www. i-glassesstore. com/

Spatial Division • Smart Glasses – Epson BT-200

Polarization Division • Polarization – Linear polarization

Polarization Division • Polarization LCD – JVC Passive Xpol system – Linear polarization • http: //www. youtube. com/watch? v=rbx 3 K 1 x. Bx. V U&feature=related

Polarization Division • Polarization (Linear) LCD – i. Z 3 D

Polarization Division • Polarization (Linear) LCD – http: //viml. nchc. org. t w/blog/paper_info. ph p? CLASS_ID=1&SUB _ID=1&PAPER_ID=14 5

Polarization Division • Linear polarization – Any effort to tilt the head sideways would result in the polarization failing, ghosting, and both eyes seeing both images. – Circular polarization has alleviated this problem.

Polarization Division • Polarization – Circularly Polarization • If light is composed of two plane waves of equal amplitude by differing in phase by 90°

Polarization Division • Polarization – Circularly Polarization

Polarization Division • Polarization – Circularly Polarization

Polarization Division • Polarization LCD – Images are displayed from top to bottom with alternative lines assigned to left and right eyes. – Resolution Penalty

Polarization Division • Polarization LCD – Advantage • • Full-color display Flicker-free Polarizing glasses (passive) are cheap Youtube – http: //www. youtube. com/watch? v=r. Zg. Npzq. IIaw&NR= 1 – http: //www. youtube. com/watch? v=Sdv 0 J 57_ U 5 g

Wavelength Division • Illustration 2 – Input: Side by Side

Wavelength Division • Standard LCD – Example • http: //www. youtube. com/watch? v=d. HG 2 IWV 1 ca. E& feature=related

Wavelength Division • Anaglyph techniques – Color separation technique – Use two complementary colors to display the left and right views respectively – Use red and green (blue) glasses to observe it – Adv. : simplicity and economical

Wavelength Division • Anaglyph Technique

Wavelength Division • Anaglyph Technique

Time Division • 120 Hz LCD – Glasses are very expensive – Shutter Glasses (Active Glasses)

Time Division • 120 Hz LCD/Projector – Glasses • NVIDIA "Geoforce" Graphics card + Projector itself needs to be NVIDIA certified • The glasses work by communicating with an external USB controller/IR (Infrared) emitter.
