MicroTiles

MicroTiles are discontinued[1] modular rear projection cube units designed, developed and marketed by Christie Digital.

The system was invented in 2005 by Christie Digital's Bob Rushby (CTO) and Mike Perkins (senior product developer) during discussions at a Tokyo hotel bar, during a business trip.

[8] According to Mike Perkins, the subjective effect of this is that the purer colors from MicroTiles are punchier, more vivid, and more engaging.

The screen is a matte-finished polycarbonate material mounted on a metal frame which is held onto the front of the tile cabinet magnetically.

All mechanical maintenance is carried out from the front of the unit, with access gained by detaching the magnetically held screen with a suction grip tool.

The ECU is also connected to the MicroTiles in a daisy chain or ring network using a customised version of the DisplayPort interface.

The ECU performs automatic calibration of light output and color control to ensure that the picture displayed is uniform across the array of tiles.

In this case one ECU arbitrates to become the master, and it assumes the role for device control; the other slave ECUs are just used for image signal processing.

This allows resolutions to be displayed on smaller tile arrays at the native 0.57 mm pixel pitch (for up to six tiles)—larger arrays need more ECUs to be added to the system, which means that multiple media player outputs will be needed to drive the extra ECUs.
