OK, for what purpose? Do you want to display datas or pictures?
B/W or color?
At night, a simple LCD TV also reflects on the windscreen, but at daylight (even sunlight) it wont't be visible.
I went to a BMW service to watch the new HUD technique. It was quite good, giving the illusion of a far floating display.
It uses a reflectory mirror AND a very strong LED enlightment.
I wanted to reproduce it but was unable to produce such an optical system...
Additional problem, it reflects double in my windscreen. At BMW I was told, there is no need for a special glass...
One of the possibilities can be to use a monochrome display from a 3-way projector (that has a high contrast) and the electronics...
