    Question Ultra Thin 7" Touchscreen Challenge - Most Suitable Monitor?

    Hi. I've been away from the Car PC scene for a long time, now I'm coming back with a new challenge... to build a CarPC into an Ultima Can Am. I've been building the car for 6mths and need to turn my attention to the interior, inc entertainment. Here's where the CarPC comes in. I plan to build a centre console housing a 7" touch screen. However, the catch is that space is very limited, so the screen needs to be super-thin and I'll have to mould it into the new console.

    Here's where I'm struggling..... If I'm going to do this, I need to keep the screen around 15-20mm thick max and as the car has no roof, it's going to need to be bright (ideally sunlight readable).

    I'd like a single cable (USB) solution, but that's not a deal breaker, size & performance is, however.

    As I've been away for so long and most of my previous bookmarks are dead, I'd like to know what the group think my options realistically are and if I'm asking too much. Please send any suggestions / thoughts with links if possible. I'll give the projects / fabrication forums a browse, but look forwards to any comments from the group.

    Thanks, Mark

    you didn't mention the overall size screen you are considering, though i imagine that it would be a 7" screen..


    overall, the screen tech has not changed much since your last time here... the biggest difference is that the screens are brighter, some have usb-only connections, and they can be upgraded with a capacitive touch layer-- though, i am not aware of any 7" screens that come from the oem with a cap. touch layer.

    overall, i do not recommend usb screens for single screen installs due to the fact that they will not display anything until after the os has loaded-- so any issues before the os loads would require a 'normal' monitor to connect and diagnose--which can be problematic if your a long ways from home..

    many of the screens are still quite bulky, so i don't think that your goal is achievable with the current batch of lilliput/xenarc models(it ought to be something that should be possible by now, but it not ).

    however, there are larger super-thin led back lit pc monitors in the 19-22" range that should fit the thickness requirement. many require 19v power, which can be accomplished with a carnetix or dc-dc-usb power supply.

    Thanks for the response. Yes, I'm just looking at a std 7" screen, I don't have the room to go any wider or higher than a 16:9 wee 7 incher.

    Also, thanks for the tip on the all-in-one USB, I hadn't appreciated the power-on limitation. So, that's set me straight there.

    Regarding the screen itself, I see a few Open-Frame screens around, which appear to be thin enough, although there's rarely a bezel of any kind to mould into a new console..... I guess an obvious option would be to get an appropriately spec'd screen and then disassemble it, keeping only the front plate. I guess then I've got to deal with mounting any other internal gubbins in a very limited space tho'. I presume many folks have done such things, are there screens out there that particularly lend themselves to such practices (i.e. by having few internal parts that need separate mounting)?

    I'd certainly appreciate any advice from those who have been there, before I start calling resellers

    Not sure where you were looking at the open frame displays from, but I include a 669 or EBY701 (Lilliput) bezel free w/purchase if you ask for it.
