New DMD part numbers | DLPC347x
❑ The DLPC347x display and light control controllers, now have new DMD part numbers
❑ These DMDs are keyed to work specifically with DLPC347x controllers
    ❑ Programmed for use in light control applications (3D machine vision, 3D printing, etc.)
❑ LC DMDs are functionally equivalent to display DMDs
❑ The overall benefit is better support for light control customers:
    ▪     Helps support longer life cycle requirements for industrial, professional and medical markets
    ▪     Helps drive future developments for light control markets, independent of display markets
