Typical Application

The DLPC6421 controller is ideal for applications requiring high brightness and high resolution displays. When two DLPC6421 display controllers are combined with the DLP470TP DMD, an FPGA, a LED power management device (DLPA3005), and other electrical, optical and mechanical components, the chipset enables bright, affordable, full 4K UHD display solutions. A typical 4K UHD system application using the two DLPC6421 controllers and DLP470TP DMD is shown in Figure 8-1, .
