DLP® Display Controller for DLP470TP (0.47 4K UHD) DMD - DLPC6421


The DLPC6421 is a digital display controller for the DLP 4K UHD display chipset. The two DLPC6421 display controllers, together with the DLP470TP DMD and DLPA3000/DLPA3005 power management comprise the chipset. This solution is a great fit for display systems that require high resolution and high brightness in a small form factor. To ensure reliable operation, the DLPC6421 display controller must always be used with the DLP470TP DMD and the DLPA3000/DLPA3005 power management integrated circuit.
