NCHC Tiled Display Wall
(TDW)
TDW TaskForce : tdw@opensource.nchc.org.tw
National Center for High Performance Computing, Hsinchu 300, Taiwan
1. Goal
TDW(A scalable display wall for the display of large, high-resolution
graphics and visualizations)
The goal of the TDW is to construct a
scalable display wall for the display
of large, high-resolution graphics and
visualizations.
2. Architecture
TDW(A scalable display wall for the display of large, high-resolution
graphics and visualizations)
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.
3. Hardware
TDW(A scalable display wall for the display of large, high-resolution
graphics and visualizations)
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.
