DLP3030-Q1: About DLP3030-Q1

Hello user5928046,

Thanks for reaching out with questions about the DLP3030-Q1 EVMs. Here are short answers, as well as some additional information that may be helpful.

1. Yes, the DLP3030PGUQ1EVM accepts HDMI as a video input.  This can come from a desktop, laptop, or any HDMI connection that can output 864x480 resolution at 60 Hz or other supported resolution. There is an HDMI-->Parallel RGB deserializer chip on the EVM electronics for easy evaluation.  For production or prototype designs, this can be changed to work with other video sources, such as FPD Link.

2.  Yes, it is possible to use the DLP3030PGUQ1EVM to form a HUD display on a windshield instead of the combiner glass system included in the DLP3030CHUDQ1EVM.  This will require a new powered mirror to redirect the image onto the windshield, for best results. The PGU EVM can be designed into a custom HUD setup for in-car development work.

If using the combiner EVM directly on a windshield, there will likely be image distortions introduced by the curvature of the windshield.  Typically, the powered mirror included in the HUD optics can be designed to cancel out these distortions.  This will require a model of the particular windshield and optical modeling software to design the mirror.

Can you give some more information about the specifications for windshield HUD you are asking about? In general, the DLP3030-Q1 based PGU can output around 70 lumens, support a field of view designed up to 10 degrees wide, and support a virtual image distance up to 15 or 20 meters.  These specifications will be determined by the optical and mechanical design of the HUD system.  Please see the Electronics and LED Driver Reference Design for AR HUD design guide (TIDUEE5) for more information about designing with these parameters.

I hope this information is helpful.  I can answer any clarifying questions you might have.

Best Regards,

Jackson
