    Thumbs up AU Optronics Screen and VGA driver board (large images)

    Well, I know I promised everyone a "review" and I will review it once I get time to play with it, but I got the display and driver board this afternoon and it's too cool to keep it from y'all another week. Initially I was getting a transflective screen as well, but the factory didn't want to deliver one unless I wanted one really bad. According to my contact they where having production problems, so I'll get it later on.

    The Display is a AU Optronics 7" Model: A070VW01 (with touch screen)
    Product Specification: Panel Only
    Product Specification: Panel with touch screen

    The VGA controller board is a Promate JLPA070VW01
    Product Specification: VGA Controller

    Part numbers:
    JLPA070VW01-2 (TFT + touch integrated, ~ 320cd)
    A070VW01 (TFT panel , 400cd)
    JDBK070F2B1P (VGA controller kit, incl. cables, inverter and OSD panel)
    JDBK070G1A0P (AV/VGA kit, same as above)
    JDBK070T1A0P (LVDS-card for A070VW01)
    JTHS070F1A0 (7'' touch panel)
    JTHC084DUA1 (USB touch controller)


    Initial thought is that it's worth every penny, it's way brighter than the Lilliput, better contrast, better image quality overall and faster.
    When the Lilliput takes ~2 seconds to switch (when changing resolution) the AU screen does it instantly.
    The brightness is enough to wash out the image, so I don't think I'll have to do a backlight upgrade.
    Another good thing iwth the TFT panel is that it's rated for automotive use, so the operating temp. range is -30 - +85 degrees celcius, that's for the panel only, with touch screen it gets worse... but as long as my screen doesn't freeze up I really don't care id the touch screen doesn't work for a few minutes
    The only annoying thing about it is that it doesn't seem to remember the previous settings, but that may just be my fault.

    The VGA controller is a dream, the basics is that it has 3 AV inputs and can detect 800X480 resolution.
    But the sweet thing about it is that everything is controllable over RS232, so you can select AV input, VGA, brighness, dimming, everything via RS232.
    For me that's perfect, because I can detect via CAN-BUS which gear the car is in and what speed, so I can then use that information to automatically switch to rearview/front camera without pressing any buttons.
    Furthermore, the car has a integrated lighting control, also readable through can-bus, so I can auto-dim the screen with the cars own dimmer.
    For those that doesn't have this option, the VGA board has a dimming input, just supply it with 0-12V and it'll do the dimming for you.

    Now, on to the images:
    First one is with the Lilli at 100% brighness and the AU at ~25%, second is with both at 100%. As you can see the AU is plenty bright. (same exposure setting on both images)


    Screen and controller.


    The kit.

    Does the screen rotate? It's a different way up in each of the different pictures.

    I assume it was the top lcd in the side by side comparison? Can you take another picture with both at 100% but adjust the exposure down so the AU looks good and we see how dark the lilliput is in comparison?

    The whole kit was $450, but that's with our hefty sales tax of 25%, import taxes and other stuff, so I'd assume that you US guys could get it for ~$350.

    Yes, the screen does rotate, you can flip the image on the VGA controller, selecting which way is UP.

    Thing is with 100% brightness that the AU doesn't look "good" as it washes out a bit.
    This is a correct exposure where the AU screen looks "normal" at 100%.

    The Display is a AU Optronics 7" Model: A070VW01 (with touch screen)
    The _panel_ is A070VW01, but the panel with factory mounted touchscreen has the article number: JLPA070VW01-2
    and I'm using the one with the touch screen allready mounted.

    No, it's not integrated in the steel frame (panel housing) which I reckon is good since you can change it if/when it fails.

    If you look at the specs. page 15 & 16, you'll see the dimentions of the touchpanel, it's glued onto the frame of the LCD panel (but still replaceable).

    That is a good looking screen! RS232 control is totally where it's at. I wish this thing had been easily available a couple of years ago when I did my install
