7” Screen Nits/Lumens?

D/5624-KIT-I.C

A family friend gave this display to me. I’m working on a project to put a screen in my car and route it through the factory harness and aftermarket system I have. All I am wondering is if this 7” touchscreen is bright enough to be seen during the day? Specific specs would help most!

    You've not mentioned the particular product you're referring to. Is it the 7" display intended for Raspberry Pi? It's not very high-res, it would look quite dated in a vehicle. Plus it would be chunky since you have to attach the Pi nearby, behind it.

    Think you might be better off with an Android or Apple tablet and run an app off that, or movies etc. For years before Bluetooth was popular, I ran an iPod touch in my car with a 1m length of custom metal braided cable for audio and power plugged into the centre armrest (with a rugged LEMO connector). Worked out great for allowing anyone in the car to select music on a bright decent quality screen although it was only small mobile phone sized, plus Internet on the iPod via a little 3G router with WiFi in the boot/trunk.
    Definitely worth considering reusing technology like old tablets or phones I think, and just develop an app for it if none already exists for your desired purpose.

    It’s for a 2001 Lexus Ls430. I’m using a grom system that allows me to use the factory OS and android OS. I can switch between either and it still looks factory. The grom system will only allow me to add a secondary display at a resolution of the original display as it’s mirroring the factory one (480p) but this display is from 2001 and it’s a very dark lcd (200nits) so this raspberry would be a nice little project if it’s bright enough to be worth my time. I’ll add some pics below to help.

    Hi,

    This won't work. What interface does your Grom system use for the secondary display?

    The Pi display has no standard external video interface to external devices like your Grom system, instead the Pi display uses a special intra-system interface over a ribbon cable, designed to attach to the Pi and nothing else (at a high level approximation). 

    Furthermore, the Pi has no video input interface either.

    Maybe the Grom system supports something thst may make it work, but I'm unfamiliar with it, and I think it's a safe bet to assume the Pi display will not be compatible in any direct way.

    The R-Pi 7" touch display is only 250nits
