  • Better electric window tint

    Get a large graphic style dot matrix LCD panel that's a clear film without a backlight and fits your windshield and make some kind of controller for it that allows you to control each pixel individually. Then use a webcam hooked up to your carputer somewhere near the driver's head to look for bright things (headlights at night, sun glare) and dim that section of the windshield while keeping the rest of it clear.

    This would also be able to tint the windows while the car is off, but use a small amount of power.

    IIRC, don't those LCDs invert their colors when you look through them the other way? That could lead to some complications I can't figure out because it's 5am.

    Anyways, all I really need is to find a place that will sell me giant clear dot matrix displays.

    And if I'm not making any sense, I'll draw some pictures in paint tomorrow because this is totally sweet and I definitely need this in my car.

    I dont think large film based LCD's are available at this time. at least not widely available outside of lab.

      I've thought of this before. The problem is that you'd have to figure out the height of the person driving. What happens when someone else drives who's shorter or taller?

      Also, one of the big issues to tackle is that the screens are blurry when they are clear. Visibility will be hindered based on this.

      Once you've solved that problem, you've just got one more problem: Software/Hardware. You'll need something fast enough to process that information. I can't fathom the programming that's involved in this... I've never been good at graphics programming.

      Good luck.

        A sensing method that measures the angle of the seatbelt, up at the top anchor on the pillar, could possibly estimate driver height. For a very tall person, the angle would approach 90 degrees, for wee people the angle would approach 180; if seatbelts are worn.
        It's been a while...

          Well no one else drives my car, and I'd assume you would code in some sort of calibration to get it just right for you. Just use different "profiles" for each person that would be driving. They already do this for seat/wheel position. IMO, the programming seems pretty simple, and the reaction time can be like 0.1 sec and I'd still be happy, it's more of a way to keep irritating glares out of your face while driving without tinting the entire windshield, and generally bright spots don't come out of nowhere. At night headlights slowly become brighter as you get closer, giving the computer more than ample time to figure everything out.

            And what about the traffic lights?

              I think the problem with trafic lights can be avoided simply by not tinting the windshield. I'm pretty sure thats illigal any way.

                I think maybe you should just read the OP..

                  yea, my bad. I read it before, but forgot about it since.
                  anyway, yea, have you been able to find this film?

                    Doesn't exist.
                    Failure is not an option....

                      It's in pre production.

                      so far they have cast Tom Cruise in the lead with Halle Berry as the girl interest.


                      I believe the Villains will be Nicole Kidman and Dustin Hoffman.

                        You can't tint your windshields for a few reasons:

                        1. Safety-Glass is designed to shatter. Tinting will prevent it from shattering and you could die easier if you go through the windshield.
                        2. Cops need to see your face. As well (even though still not legal) photo enforced intersections need to see your face.
                        3. Night time driving is seriously affected by tint... The windscreen is the worst place for it.

                        Aside from that, there isn't any "film" that could do this. At least not on the market. OLED screens in the future would work, but still, not ready for public yet.

                          What if you apply the nonexistant film to the windshield in little itty bitty pixel sized pieces? Would that be safe then?

                          I don't go around breaking the law, but I also don't give a rat's tail about what big bro 'needs' my vehicle to be .

                            I know what you're saying. But there are better ways to go about this. Perhaps glasses. would work far better. Completely clear with an LCD matrix display or Quartz matrix display. That way there would be no need for calibration of height and would be a bit more simple to find a display the right size.

                            It's not Johny-Law that you should be worried about. It really is the safety issue (unless you plan to wear a 4 or 5 point harness when you drive.)

                              Agreed, full tint on the front is a bad idea all around. With Siemens VDO's HUD and some others, I'm sure we'll see how the OEMs tackle these things from a safety point of view.

                              On a related note, few things are less safe than driving west into a vegas sunset.
