What is Self-Scanned Amorphous Silicon Integrated Display (SASID)? - Definition from WhatIs.com


Self-Scanned Amorphous Silicon Integrated Display (SASID)

Part of the Hardware glossary:

Self-Scanned Amorphous Silicon Integrated Display (SASID) is the trade name for an active-matrix liquid crystal display (AMLCD) technology developed by Sarnoff Corporation. The technology is intended primarily for flat-panel displays in notebook and portable computers, and for projection panels.

The hallmarks of the SASID are the amorphous silicon (aSi or a-Si) manufacturing process and the self-scanning feature. The horizontal and vertical scanning circuitry, rather than being external to the display, is incorporated directly on the glass substrate of the panel. This reduces the cost of manufacture by up to 35 percent, according to Sarnoff, and enhances reliability by minimizing the number of interconnects.

Sarnoff estimates that the average useful life of preliminary SASID designs is more than 10,000 hours at 70 degrees centigrade, and the random failure rate is approximately half that of most other AMLCDs. In addition, SASIDs are said to be brighter than most other AMLCDs, offer an image resolution of more than 200 pixels per inch, provide excellent contrast, and consume minimal power (typically less than 200 milliwatts). The SASID is compatible with existing pixel designs, and offers equivalent system interaction to other AMLCDs.
