    Lightbulb LCD Displays for AUS$75

    I was at a computer swap meet today here in Melbourne, Australia and a vendor had second hand notebook LCD's for only $75 (US$45). If anyone is interested I've got a phone number.

    What do I need to get this thing workig directly from my video card (which is on the motherboard - to save room)?

    Mate $75 is only the begining...
    then you need a controller for it, which is not so easy to find here in Oz
    and even if you find one it will cost you around AU$400.

    So what u recon, is it worth it?

    well i had the same idea, i still do infact. lack of funds has hindered me right now though. anyways, you can find some lcd controller cards. any 15pin vga out video card will NOT work with a digital lcd screen. Ati sells a lcd controller card as do a few other smaller companies. I don't know what Au sells but you can get them in the US pretty easily. Depending on the screen you might need a video inverter but it might come with the screen. Who knows. You will also need the specs for the screen (pin outs mainly, amount of power needed, etc...) and the pin outs for the lcd controller. Perhaps once you buy all this stuff and put time into it and it works it'll be much sharper than any ntsc lcd screen and probably bigger. I mean ntsc is great and easy but i have checked with people that work with lcds all the time and this is possible. i'd rather buy an 8.4" screen for $75, then a controller card for $120 and spend just around the same amount for a 5" screen that you have to make the text bigger to read. You can run 640x480 with clarity.

    Well idea itself sounds good but bit expencive for some like my self here in Australia. First of all the AU$ and US$ has around 60% in value wich mean if the controller is US$200 in US, we gona end up paying around AU$350 - 380 plus another US$40 for the shipping cost.
    By the way i got this Sharp 8.5" LCD screen form the laptop (model - LQ9D023). Couldnt find any datasheet for it on the web, i even sent few emails to different companies but got no reply. Also i got a controller for the LCD screen based on CHIP chips (model 65535) but the stupid thing doesnt have nor model numbers nor manufacturer name.
    So basicly i got the whole package but dont have enough data to put it toghter.

    So does anybody uses a controller based on the chipset if so, do have any datasheet or any other relevent info on... that would be a great help for me!
    THanx guys!

    Hmmm, I never heard of that particular Chips 'n' Tech graphics processor before. Go here for data sheets on the rest of similar chips, most of which drive LCDs directly (digitally):
    http://developer.intel.com/design/gr...obilegraphics/

    There are data sheets giving connection details and register programming details for driver writing for several example LCDs. I've written register level video drivers for Chips chips before (specifically the 69000), and it's not too difficult.

    The mobo I'm using (EM-586 from Lanner Electronics) has a Chips 65555 graphics processor on, and a digital LCD port on it. Data for the mobo (for example port layouts) can be found at:
    http://www.lanner-usa.com/Products/S...586/EM-586.htm

    Probably quite a cost effective way of getting a mobo with an LCD controller on it (and also getting a very small unit as it's an embedded mobo). I was certainly considering using a digital LCD for a while, until I decided that I don't have room in my car for a large screen.
