The DLP391TP 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, DLPC8445V 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.
