  1. NCHC Tiled Display Wall (TDW) TDW TaskForce : tdw@opensource.nchc.org.tw 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 projectors3. 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 WA8168 320cm*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.

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

  9. 5. Application TDW (A scalable display wall for the display of large, high-resolution graphics and visualizations)
