IEC TC100
CHINA NC

2. Background Multi-screen LCD display systems– Part 1: Conceptual model
-. This document specifies a conceptual model of multi-screen LCD display systems. This document defines typical functional components to compose multi-screen LCD systems and describes the system structure and signal flow. The document also clarifies signal processing in the system to create multi-screen images from a single video signal input.
Multi-screen LCD display systems– Part 2: Measuring methods
-. This document specifies measuring methods of multi-screen LCD display systems. To evaluate the characteristics of multi-screen display systems, The following measurement items are specified:
* Gap( physical, optical)--- Detail splicing precision;
* Image dislocation—Picture display accuracy of Multiscreen LCD display system;
* Installation tolerance---The flatness of terminal in surface and vertical direction;
* Brightness uniformity--- Adjacent units brightness uniformity
* etc

Our Suggestions
The conceptual model is as important as the measuring methods. It’s the basis of the whole series standards. So we recommend the part-1（Conceptual model）to be an IS.
