*TN LCOS devices show a contrast in CFS mode >1000:1 using compensators like trim retarders or QWP´s, whereas in monochrome applications the sequential contrast could be above 3000:1, even higher with VAN-type LCOS in normally black mode also with compensator optics.

HEO 7200 Developer Kit

HEO 7200 LCOS Developer KitThe HEO 7200 kit is used to control an LCOS (Liquid Crystal-on-Silicon) active matrix reflective mode LCD with 1280 X 720 pixel resolution and a 0.37” diagonal.

The color field sequential microdisplay offers full color video images and supports 5 color fields (RGBRG) at 60 Hz. input video frame rate.

The content is addressed via a standard HDMI (High Definition Multimedia Interface) signal e.g. by a PC’s graphics card. Basically, the LCOS display works like an extended monitor. Hence this plug and play kit guaranties a quick start-up and easy usage.

The kit is highly programmable and comes with an UVC tool that communicates via an USB port. This communication port connects a PC to the driver chip allowing various configurations e.g. RGBRG -mode, dithering modes for reduced bandwidth, gamma correction etc.
