    NITS... CR... & Viewing Angle...Values for success

    Just wanted to ask around, people whom already installed LCDs inside their vehicles. What value for Brightness (nits), Contrast Ratio (CR), and Viewing angles have you used thats led to an LCD with good viewing quality during a bright sunny day and dark nights....

    Thanks

    i was using the 6.5" TFT from earthLCD with touchscreen and it was perfectly sunlight readable with 300nits if i remember it well, even when the sun was shining directly on the touchscreen!. although at night i had to switch it off. i now have a wiring plan to hook up a potentiometer to it so i can dim the light, but as of last saturday my display seems to be broken :-(

    yeah, too bright, but only at night.. too bright means, it is so bright that it is very distracting and it makes it hard to see everything outside the car, plus everybody who passes can see your face being lit up by the display ;-)

    but there is a software tool on this board which helps you to get it darker.. darker never really is a problem.. only brighter is hard to get.. so i would'nt bother (except for if you only use it at night heeh) ..

    plus: most inverters support a dimming function.. with mine it is pretty simple.. just attach a 10k potentiometer over two pins and you can dim the backlight.. just check the tech-sheet for your inverter...

    another little remark... since one of the two light-tubes in my screen are not working anymore (see my other recent post) i am now driving around with approx. 150 nits.. (half of the 300 i'd have with both i guess.. ) ... and 150 is good to bi driven at night.. not too bright but on the upper limit i'd say... during the day it is rather dark. when the sun shines driectly on it you can't really read it anymore..
    so another easy solution to make your screen darker would just be to switch one of the two tubes off.. but this is a very ugly solution, since your display is then bright on one side and dark on the other.. (but at night it wasn't that clear.. only if you look very close, so it will work as a "last" solution :-) )

    cheers
