Three Dimension 2

Outline Theme introduction Introduce the technology Life application Summary 3

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!  + 6~8 cm  4

Outline Theme introduction Introduce the technology Life application Summary 5

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

3D Technology  Two   areas Seeing with glasses Using naked eye 7

Technique with glasses 8

Anaglyph (red-blue) glasses 1.Anaglyph images  2.two color glasses (Anaglyph glasses)  3.Images are made of two color layers  cyan (青色) red chromatically opposite 9

Polarization glasses(偏光眼鏡)  How does it work? two projectors 2. use polarized light (偏光) principle 3. see separate image in our eyes. 4. Combine two image to cause 3D secne 1. 10

Technique -using naked eye 11

Parallax barrier(視差屏障式)  How does it work? 1. 2. Use liquid crystal display (LCD) consist of a layer of precision slits (to filter the light) LCD screen precision slits different images 12

Lenticular Lens(柱狀透鏡式)  How does it work? 1. 2. an array of magnifying lenses(凸透鏡) on the screen refract light to show different images to the eyes Lenticular Lens different images 13

Directional Backlight(指向光源式)  How does it work? 1. 2. use two set of LED that show two images alternately in high speed The left part of the backlight is related to the right eye, and vice versa(反之亦然). 14

Outline Theme introduction Introduce the technology Life application Summary 15

3D movie   Use two projectors to project a simultaneous(同 步的) picture on the screen Use glasses to see the 3D effect 16

3D TV  With glasses V.S. Naked eye  Experience sharing: 2D →3D transformation was not good enough 17

Toshiba’s products 3D TV wall Using Lenticular Lens  In the end of this year  NT:90000 ,NT:45000  18

3D computer 19

Future applications  Holo AD Presenting 20

Future applications  3D Projection (全像投影) 21

Outline Theme introduction Introduce the technology Life application Summary 22

Summary  3D technology, being a trend, has a lot of potentials.  In the past impossible  unimaginable   Our  Nowadays contrast WHY? Rapid development  advanced ＆ stunning  dream is “visualized”!!! 23

Summary  Why   is this possible? desire ＆ courage → drive innovation Base on the past while striving to transcend 3D 2D  24

Summary  James Camero’s speech  Failure   is an option, but fear is not.” Don’t dare to dream. Realize them despite difficulties. 25
