How does heads-up-display (HUD) work?

[@ATLLEO1170]

i can see this to be a physics question in a future high school science test.:)

[@raus_mit_Islam]

The most important safety feature in a car, because it helps keep yr eyes on the road!

[@emperror85]

Nice self-explanatory image! Cool thing.

[@drivingthenation]

Thanks. I'm surprised how many people have enjoyed this little video.

Sprechen sie deutsch, ja? Teachen sie physics, ja? Speaken sie gut englisch mit thick aber enjoyable accent, ja? Writing ich ins annoying German-English gibberish, ja?

So when are we going to get cars that shoots heat seeking missiles?

[@drivingthenation]

don't we already have them? oh that's right, they're not heat-seeking :)

Are there HUD's that will display on the upper part the windshield, slightly above your direct line of sight?

[@drivingthenation]

There are HUD displays that move, so yes.

I feel like this is an advanced pepper's ghost effect.

[@iftikharahmad8435]

Hello, can you please tell me about the Light source. Also combine function of light source and display? Thank you

[@SuperRiki81]

Jawohl! Ja!

[@nikolaosberatlis3942]

I am not sure what the glare trap lens is exactly? Does it have a reflective coating applied to it?

[@drivingthenation]

I don't know either and this was from 2014. I am sure they upgraded since then.

[@antonen87]

@@drivingthenation In my humble opinion, they probably rather wouldn't upgrade much. The technology is quite mature, having been used already for around 80 years.

[@king_james_official]

⁠@@antonen87do you maybe know a book or some articles about this? i'd like to learn more about the glare trap and windshield coating

[@sanelhirkic2858]

Is there anything special about the glare trap lens/cover or is it just a sheet of plastic? I have a second hand continental HUD and the cover is scratched up. Wondering if it's ok to polish up or is there some sort of special coating applied to the plastic. Thanks!

[@drivingthenation]

go to the dealership and ask them.

Can someone from outside see what is being projected on the windshield?

[@drivingthenation]

good question - I don't think so. I will check

[@drivingthenation]

I got these answers from Continental - How big is the initial display? There is a range of sizes that can be used for Image Generation. Our TFT HUDs use displays from 1.3" to 1.6" in size. What is the magnification of the convex mirror? There is no convex mirror in our system. Can someone from outside see what is being projected on the windshield? No, not as a projected image. If someone looked through the windshield and down at the dash board, they may be able to see the display image, but it would be very small.

[@WildBuffalo11]

what does the fold mirror reduce?

[@drivingthenation]

+Bill McDonald Thanks Bill. We just had Continental show us their mirror less side view cameras. We haven't put them up yet. I will try to put a link here when we do.

[@emperror85]

It reduces the total size of the box. Without the mirror the projector would need to be placed at the same distance from the mirror, but on the right side in the image. From the size of the thing, I think that's about where you'd want your steering wheel. By using a mirror, the projector can be put on the left side instead. I presume they call it a fold mirror because the light path is "folded".

[@azmatali1159]

can you provide a pdf for this?

[@drivingthenation]

sorry, one was not given.

Think of it as "you know" That way it is just irritating, not condescending :)

I hate when ignorant Americans, who only care about guns and gaming, complain about the mistakes English speaking Germans do, when they can't spell even a German two letter word correctly themselves. :)
