MEMS (micro electro mechanical systems) assembly made for a blinding output video projection unit. Consists of a 1" L x .78" W reflective mirror assembly which contains over a million micro mirrors. Each mirror represents one pixel. When a mirror receives a signal it moves slightly, directing the light striking it to hit a lens. A typical projector uses 3 of these units (RGB). The mirror assembly is mounted on a 5" L flat flex cable which terminates in a 100 pin female connector mounted on top of the flex cable. These assemblies may have slight scratches and or slight problems as listed on some of them by the QC Dept. We have no info on these and no way of testing them so we are selling them "AS IS" no returns. The original cost was hundreds of dollars each. Package of 5.
