This projector uses three high-power LEDs to illuminate Texas Instruments’ (TI) .45” WXGA DMD, displaying over 1 million pixels in a single image. The projector electronics contain all the power and capability of Texas Instruments’ reference design but also offers multiple control options, a custom GUI, and Beaglebone Green compatibility.
Optional Pattern Expansion Module
An optional Pattern Expansion Module (PEM) add-on is available, which is based on the Beagle-Bone development platform and is installed on headers added to the LC4500 controller board. It expands the functionality of the LC4500 controller board by adding:
Ethernet interface for control and communication
Ability to operate pattern sequences at a fixed frame rate (50Hz per 24-bit frame) regardless of the number of patterns or bitplanes in the pattern sequence
Ability to update individual stored patterns without reprogramming the entire DLP4500 chipset firmware
Separate graphical user interface including PEM and general chipset controls
If desired a PEM-equipped controller board may be operated in the same way as one without a PEM using the standard GUI and USB interface with no loss of functionality or performance.
