1 NCHC Tiled Display Wall (TDW) TDW TaskForce : National Center for High Performance Computing, Hsinchu 300, Taiwan

2 1. Goal TDW (A scalable display wall for the display of large, high-resolution graphics and visualizations)

3 The goal of the TDW is to construct a scalable display wall for the display of large, high-resolution graphics and visualizations.

4 2. Architecture TDW (A scalable display wall for the display of large, high-resolution graphics and visualizations)

5 TDW character: Back-projection, Easy alignment by Controlling projectors within RS232 protocol. Why to need alignment: calibration of projection image. 1. Projector: Projector misplacement, causing overlap or gap. 2. Photometric and colorimetric non-uniformity among the projectors 3. Deformed image: Projection on non-smooth surface.

6 3. Hardware TDW (A scalable display wall for the display of large, high-resolution graphics and visualizations)

7 1. 背投螢幕 (Screen):ScanVision WA cm*180cm\ 穿透型 偏光片 glasses 材質 2. 背投影固定架 (Frame): 可調式鋁和金支架,固定投影機以及具位 置調整 (Fixed projrction) 。 3. 投影機 (Projectors):24 (2 per tile in 4x3 grid) NEC LT260(1024 x 768)DLP Projectors. 4. 主機 (Computers):13 (12 projector + 1 Server) XEON 2.6Ghz AG Prestonia, 1GB RAM * 4, (GF4 Ti4800SE DDR,DVI,TVout- projector), (Quadro FX 2000 AGP8x-Server), running Debien. 5. 傳輸 (Network):INTEL PWLA8490XT 10/100/1000Mbps,PCI [10/100/1000Mbps] switch.
