1 3D Display Technology TYWu

2 3D Display Technology Seeing in Depth –Not only X and Y axis, but also Z –Stereoscopic Image Technologies –Eyeglass –Eyeglassless

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

4 Polarization Division Polarization –Linear polarization

5 Polarization Division Polarization LCD –JVC Passive Xpol system –Linear polarization U&feature=related

6 Polarization Division Polarization (Linear) LCD –iZ3D

7 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

8 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.

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

10 Polarization Division Polarization –Circularly Polarization

11 Polarization Division Polarization –Circularly Polarization

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

13 Polarization Division Polarization LCD –Advantage Full-color display Flicker-free Polarizing glasses (passive) are cheap Youtube –http://www.youtube.com/watch?v=rZgNpzqIIaw&NR= 1http://www.youtube.com/watch?v=rZgNpzqIIaw&NR= 1 –http://www.youtube.com/watch?v=Sdv0J57_ U5ghttp://www.youtube.com/watch?v=Sdv0J57_ U5g

14 Polarization Division Two Projectors

15 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

16 Wavelength Division Illustration 1

17 Wavelength Division Illustration 2 –Input: Side by Side

18 Wavelength Division Standard LCD –Example &feature=related

19 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

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

24 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.

25 Time Division 120 Hz LCD –3D Wired Shutter Glasses (Cheap) –http://www.youtube.com/watch?v=mM9NnN9Cebc

26 Time Division DLP 3D Ready Projector link.aspx

27 Time Division 利用 DMD (Digital Micromirror Device) 反應 速度高達 16~25μs (40~62.5 KHz) 的特性,在 左右視角畫面之間插入 2ms 的灰階訊號 (Gray Scale Signals) 畫面,快門 式眼鏡內建 Sensor 偵側畫 面灰階訊號藉以切換左右 眼 DLP-Link 優點: (1) 無需 同步訊號發射器; (2) 投影 機端無附加硬體成本,業 者導入速度快

31 Troubles 人眼雖對焦在 3D 銀幕上,但凝視不同距離 的 3D 影像內容,兩眼內聚夾角會改變,違 反對焦與內聚同步改變的自然現象。 – 經訓練能適應這種不自然的觀看環境,但跟 2D 影像相比,兩眼內聚夾角如隨 3D 內容不斷改變, 容易使控制眼球的肌肉疲勞。 立體視覺就像色盲一樣,不是人人都能感 受得到,約有百分之四人沒有立體視覺, 一成五的人立體視覺異常,這些人都不適 合觀看 3D 影像。
