At the ISE-2010 event Christie introduce a new product called Microtiles. The new digital canvas!
Christie MicroTiles provide the capability to capture your audiences attention your way, just as you envisioned it, without having worry if there is a technology out there worthy of displaying your content. Uniting spectacular colors, superior image quality and modular flexibility like no other visual solution can.

The Christie MicroTiles is a DLP System with LED light source. The modul is 408x306 mm (WxH). The screen size is 20 inch 510 mm diagonal. The pixel pitch is 0.567x0.567 mm. The maximum brightness is 800 nits (cd/m²)
The LED lifespan 50% brightness is about 65.000 hours.

The Christie MicroTiles system represents a huge step forward in large-format digital display technology, offering superior color and image reproduction, the widest possible viewing angles, and a near absence of seams on display walls, with only a 1mm gap between the tiles. The groundbreaking LED- and DLP®-based system is designed for long, reliable commercial use in public areas, with no lamps or other consumable parts to replace. Christie engineers designed the MicroTiles to be fully and easily serviced from the front. The tiles are “self-aware” – meaning that time-consuming and costly color calibration needed to keep conventional “video walls” looking uniform, is automatically completed by the sensors built into the MicroTiles.
