3 Description
The DLP3944-Q1 digital micromirror device (DMD) is
a digitally controlled micro-electro-mechanical system
(MEMS) spatial light modulator (SLM) that enables
bright 4K UHD display systems. The TI DLP®
Products 0.39” 4K UHD chipset is composed of the
DMD, DLPC431 display controller, and DLPA3085 /
DLPA3082 PMIC and illumination driver. The compact
physical size of the chipset provides a complete
system solution that enables small form factor 4K
UHD displays.
