DLP3021LEQ1EVM Evaluation Module
ABSTRACT
TI's DLP
®
technology offers a fully programmable and high-resolution solution for automotive dynamic ground
projection (DGP) applications. With nearly half a million addressable pixels per module using a WVGA (864
× 480) input resolution, DLP technology exceeds the resolution of existing ground projections technologies.
Dynamic ground projection technology, with the ability to display any static or video pattern within the same
module, can re-invent consumers’ perceptions on small projector lighting by providing new, innovative lighting
capabilities. Examples include automotive light “carpets” that can illuminate the surrounding area outside a
vehicle or project vehicle information such as the EV charge level and range remaining, tire pressure warnings,
traffic warnings, turn signaling, check engine light warning, gas level/range, etc. from a side mirror. Ground
illumination has other enhancement features to help cars communicate with drivers and pedestrians, including
corner lighting, reverse lighting, vehicle customization, and parking indicators.
The DLP3021LEQ1EVM is the DLP3021-Q1 Light Engine Evaluation Module (EVM) that allows for accelerated
evaluation of the DLP3021-Q1 chipset with the inclusion of a DLP3021-Q1 light engine. This module brings
together a set of components including the DLP3021-Q1 DMD, the FPGA based DMD controller, and the
TPS65100 PMIC to provide an efficient system for evaluation of dynamic ground projection technology. When
combined with a computer for GUI control, the evaluation module can be used in a laboratory setting to
demonstrate features such as:
