*SID-MAC Presentation*

Digital Micro Shutter Technology for Full Color and Video Displays

Jignesh Ghandi, Pixtronix

*Columbia University*

*Abstract:*

Pixtronix has developed the Digital Micro Shutter (DMSTM) Technology which

enables low power direct view displays with exceptional image quality as

well as application agility. DMSTM technology is based on MEMS

micro-shutters fabricated on active TFT backplanes. This enables the

development of color sequential, time division gray scale, direct-view

displays achieving breakthrough performance. The power consumption is ˝ to

Ľ of the power consumption of comparable TFT-LCD and OLED display

modules. A recycling backlight and display cavity and low power TFT designs

ensure low power consumption. The device has excellent sunlight readability

in transflective color and monochrome reflective modes and can be actively

modified between 24 bit color video and B&W static monochrome modes through

the use of Application Agility. These displays have been publicly released

by Samsung and Hitachi Displays. Dr. Ghandi’s presentation will discuss

the technology, device structure and achieved performance of these devices.
