*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 2220 Developer Kit

HEO 2220 LCOS Developer KitThe HEO 2220 kit is used to control an LCOS (Liquid Crystal-on-Silicon) active matrix reflective mode LCD with 1920 X 1080 pixel resolution and a 0.39” diagonal.

The color field sequential microdisplay is fast enough to handle all three primary colors, in order to deliver full color video images. The microdisplay supports six color fields (RGBRGB) at 60 Hz input video frame rate.

The driver ASIC is embedded in the LCoS microdisplay itself. This saves board space and makes integration more convenient. The display can accept video data input via a 4-lane MIPI DSI.

The content is addressed via a standard DisplayPort 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 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.
