DESCRIPTION
The DLPC200 performs image processing and control, along with DMD data formatting, for driving a 0.55 XGA
DMD (DLP5500).
The DLPC200 is one of three components in the 0.55 XGA Chipset (see Figure 1). Proper function and operation
of the DLP5500 requires that it be used in conjunction with the other components of the 0.55 XGA Chip-Set.
Refer to the 0.55 XGA Chip-Set Data Sheet for further details (TI literature number DLPZ004).
In DLP electronics solutions, image data is 100% digital from the DLPC200 input port to the image projected on
to the display screen. The image stays in digital form and is never converted into an analog signal. The
DLPC200 processes the digital input image and converts the data into a format needed by the DMD. The DMD
then reflects light to the screen using binary pulse-width-modulation (PWM) for each pixel mirror.
The DLPC200 interfaces with an LED driver via an SPI interface. It sends strobes to indicate when each of the
red, green, blue or infrared LEDs should be enabled or disabled and command packets are used to control the
brightness of the LEDs.
Commands or programmable patterns can be input to the DLPC200 over either a SPI interface or an USB
interface. When patterns are used the DLPC200 can be synchronized to a camera or external source. This
allows the external interface to sync to the patterns displayed or for the patterns to be synchronized to the
external source.
The DLCP200 allows the user to redefine the display order of the patterns that have been downloaded to
memory. This allows any pattern stored in memory to be displayed in any order. Degamma and dithering are
never applied to patterns but can be applied to data processed through either of the two pixel ports.
