    Possible 8.4" LVDS 1024x768 LCD?

    I saw this today, and thought that this might be an option:

    http://www.optrex.com/Products/PartD...FW-A-AA&bhcp=1


    Apollo Displays actually post sample quantity (1) prices:

    http://www.apollodisplays.com/mskit....9D084U-FW-A-AA

    The LCD panel itself is $443, the inverter is about $38, a resistive touch-panel is about $50, and the USB touch controller is about $25.

    8.4" 4:3 screen, LVDS interface, 300 nits, 250/1 contrast.

    300 nits should be bright enough, shouldn't it?


    They do appear to offer quotes for quantities as low as 10.

    I wonder if they would sell sample quantities to me...

    it's a 1/2" less. But I'm pretty sure saving $150 (after the accessories) is worth it.

    It only does 640x480 - the input takes up to 1024x768, but the LCD panel itself has a much lower resolution.


    It's also out of stock..

    Well, that's out, as Apollo Displays won't sell to consumers.. some insurance restriction.

    My other option, from a local company called eVision Displays, is an 8.4" LVDS LCD that does 800x600.

    It's not 1024x768, but 800x600 is far better than only 640x480.

    The panel is basically the same as this model, but it's been replaced by a newer model that's brighter:

    http://www.evisiondisplays.com/evd084s01-dsc.html

    The replacement part number is EVD084S03-DSC, -DSCT with the touch-screen.


    I was able to get a price quote from them, and they'll sell to me if I pay with a credit card.

    The price for the LCD w/TS panel is $428.00.

    I called them up to get the price quote - they can provide the LCD, the USB touch screen controller ($25), and the LVDS interface cable.


    I think I've found the LCD panel I'll use for my project.

    I probably won't be able to get around to actually buying the parts until April or May, however.

    SImply just have someone with a DBA buy them, problem solved. or see if Arman wants to add 15% to the cost and but them for us.

    Unfortunately, it's not quite as simple as getting a DBA - I used to have a Doing-Business-As certificate, so I'm somewhat familiar with them.

    In order to get quotes and a sales contract, you usually have to forecast how many LCD's you'll expect to sell in a year, and other related red-tape.


    In any case, I got a full quote from www.evisiondisplays.com - they're a company about 20 miles from where I live, and they take LCD panels from AU Optronics and upgrade them with brightness/contrast additions and touch panels.

    Part numbers/prices:

    LCD panel with Touchscreen EVD084S03-DSCT $428.00
    Inverter CXA-K0612-VSL $25.00
    Inverter input cable 51021-05-12D $3.00
    LCD panel cable DF19G-20S-12D $10.00
    USB Touch screen controller N16B-0558-B710 $25.00
    T/S cont. USB cable Cable/RTP/USB $20.00

    Subtotal $511.00
    Tax (GA State) $30.66
    Total $541.66

    The specs on the LCD are based on this model, I believe:
    http://www.auo.com/english/products/...&product_id=23

    But with the brightness enhancements + the touchscreen, I believe the brightness would actually be somewhere around 350-400 NITS, with a contrast ratio of about 250-300:1.

    I don't have the exact specs, but based on eVision's previous models, it's a good guess.

    8.4" diagonal, 1-channel 18-bit LVDS (18-bit color, 262k), 800x600 native resolution, 350-400 NITS, 250-300:1 contrast.


    And with the half-assembled LCD interface cable, all I'd have to do is buy the other end's connectors and pins (about $7), solder the pins on the wires, and assemble the motherboard-side connector myself.

    Of course, the cable assembly they give you is only 12" long, but I don't think that will be a problem, as the motherboard will be right behind the LCD..
