3D Display Technology TYWu
3D Display Technology Seeing in Depth –Not only X and Y axis, but also Z –Stereoscopic Image Technologies –Eyeglass –Eyeglassless
Spatial Division Head Mounted Displays (HMD) –http://www.i-glassesstore.com/
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°
Wavelength Division Standard LCD –Red/Blue method –Japan’s BS11 satellite channel Side-by-Side –Method adopted by Arisawa –Line-by-Line –Advantage Glasses (passive) are very cheap
Wavelength Division Illustration 1
Wavelength Division Illustration 2 –Input: Side by Side
Wavelength Division Standard LCD –Example &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
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.
