The DLPC23x-Q1digital micromirror display (DMD) controller for automotive applications is used in chipsets for interior applications such as HUD and exterior application such as high resolution headlight. The DLP5530-Q1 chipset includes a 0.55” DMD and the DLP4620-Q1 chipset includes a 0.46" DMD. Both chipsets also include the TPS99000-Q1 System Management and Illumination controller. The DLPC23x-Q1 integrates an embedded processor with error code correction (SECDED ECC), enabling host control and real-time feedback, on-chip diagnostics, and system monitoring functions. On-chip SRAM is included to remove the need for external DRAM. Combined with the TPS99000-Q1, the DLPC23x-Q1 supports high dynamic range dimming of over 5000:1 for HUD applications. Sub-LVDS 600-MHz DMD interface allows high DMD refresh rates to generate seamless and brilliant digital images, while simultaneously reducing radiated emissions.
To aid in the design and manufacture of automotive qualified projectors based on DLP technology, there are a number of established optical module manufacturers and design houses that can be leveraged to support your design.
