Choosing between a Light Control or display chipset may be challenging for developers who are less acquainted with the DLP® portfolio. The pros and cons to be considered between these chipsets lies in the features offered by the DLP® controllers.
Display controllers support image processing to optimize image quality displayed, including data compression. These chipsets can support up to 240 Hz input frame rates. Supported input source modes include test pattern generator (an internal generated test pattern intended for image calibration), splash screen (to display internally stored images), and external video support (which may include DSI, parallel, or FPD-link inputs depending on the chosen chipset).
Light Control controllers are designed for precise pixel to pixel mapping applications. These controllers can put up to 32,522Hz (1-bit) and 4069 Hz (8-bit) high speed patterns with programmable exposure times for flexible internal and external pattern streaming modes in addition to the input support modes supported by the display controllers. The Light Control systems support flexible trigger signals for camera or sensor synchronization.
