7.2 Typical Application

The DLP391TP DMD, combined with DLPC8445V digital controller and a power management device, provides full 4K UHD resolution for bright, colorful display applications. See Figure 7-1, which shows the system components needed along with the LED configuration of the DLP 0.39" 4K UHD chipset. The components include the DLP391TP DMD, the DLPC8445V display controller, and the DLPA3085 / DLPA3082 PMIC and LED driver.
