Stereoscopic vision( 立體視覺 )
Principles:Two eyes see different images ( 6~8cm)Angle of parallax( 視差 ) (to judge distance)
→“Stereoscopic vision” appears!

Most Important Concept The technologies to be introduced all have the
same purpose:
6
To make your left eye and right eye see different images in order to create the 3D effect!

3D Technology
Two areasSeeing with glassesUsing naked eye

Technique with glasses

Anaglyph (red-blue) glasses
1.Anaglyph images 2.two color glasses (Anaglyph glasses) 3.Images are made of two color layers
9
cyan ( 青色 )
red
chromatically opposite
10
Polarization glasses( 偏光眼鏡 )
How does it work?1. two projectors
2. use polarized light ( 偏光 ) principle
3. see separate image in our eyes.
4. Combine two image to cause 3D secne

11
Technique -using naked eye

Parallax barrier( 視差屏障式 )
How does it work?1. Use liquid crystal display (LCD)
2. consist of a layer of precision slits (to filter the light)

precision slits
LCD screen
different images
13
Lenticular Lens( 柱狀透鏡式 )
How does it work?1. an array of magnifying lenses( 凸透鏡 ) on the
screen
2. refract light to show different images to the eyes
13
Lenticular Lens
different images
14
Directional Backlight( 指向光源式 ) How does it work?
14
1. use two set of LED that show two images
alternately in high speed
2. The left part of the backlight is related to the right eye, and vice versa( 反之亦然 ).

In the past impossibleunimaginable
NowadaysRapid developmentadvanced & stunning
contrast
Our dream is “visualized”!!!
WHY?
