3 Description

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.
