Touring the available Nokia LCD screens

[Rossum's] taking a look at the Nokia LCD screens that are both plentiful and begging to be bent to your will. For quite some time the Nokia 6100 screens have been used in a lot hacks, but he wanted to see what else is out there. He digs into his junk box of cell phones and comes up with a couple to test; the Nokia 6101 and Nokia 2760. The screens use a 3-wire SPI interface, which he sniffs out with a logic analyzer. At power-up the cellphone polls the screen to determine which type of LCD controller is connected. [Rossum] grabs these commands from the logic analyzer and uses it to determine the hardware in use with each screen.

He made himself a nice breakout board which has connectors for several different screens. The firmware he’s using detects when a screen is attached and switches to the applicable protocol for that display. Take a look at the video after the break.

    Sweet break-out board.

    Next project: Make all the screens function together in a multi-monitor like setup.

  2. Mr Hacker says:

    how about throwing in a driver circuit and a adapter , external screen ready

  3. Trollicus says:

    I have a small(but growing) collection of screens(including some used in this project)

    I have no source of these connectors, and I’m wary of soldering them although I have soldered some in the past, it’s no fun.

    At least having a pinout will allow me to etch a board with a little more certainty. It’s always nice to have someone to follow. Just knowing it’s a 3 wire spi makes them more interesting for me. I honestly took one look at the connector and put them in a drawer.

    If you do decide to sell these breakout boards(as a kit or assembled) You have one waiting customer here.

    i have a small collection of crap that i am too dumb or lazy to hack. it consists of one completely disassembled samsung impression. which had the most amazing screen i’ve ever had (amoled) , more vibrant/lifelike than my current cellphone.. a laptop screen and corresponding touchpad. the end, i said small. who wants it?

  5. Eirinn says:

    @Jeditalian I know how you feel, i got a collection of screens too that i’m too dumb to use :S

  6. mowcius says:

    Touchpads are pretty easy to use. Just find out the PS2 pinout and you’re away.

    If you wanna get rid of that display I’m willing to take it :D

    So much win! :D

    He has schematics on the site, and says he’ll be posting code and PCBs soon on Sourceforge.

    I have some AVR assembly code for using the sed13xx controller if anyone is interested.

    It’s just the basics, write ascii characters and bmp graphics. If you want to use the extra features of the controller you should be able to get them from the data sheet as they are pretty straightforward. Right now I have a large 5″x2.75″ Hyundai HG25604 connected to an AVRMega16 (it uses the SED1330F but the SED13xx series is mostly the same startup) It’s the one from all electronics($18.50) and makes a good beginner project for those just getting started with graphic LCD’s This one uses a parallel interface, but switching to SPI is just a few lines of code to change.

    Nice little project. He should sell the boards and make a few $$, I’d probably buy a couple.

  10. Xtremegamer says:

    mozaic with nokia screen comes to mind :)

    anyone up for the challange ?

    if you do make one with at least 100 nokia screen , i’ll donate 30$US to your paypal :)

    ,Greetz

  11. hey that is very nice!

    The demo was nice. The soundtrack was awesome!

    “I have no source of these connectors, and I’m wary of soldering them although I have soldered some in the past, it’s no fun.”

    The Nokia 6101 has a flexi-cable connecting the screen to the mainboard where the signals are carried along separate wires. Should be relatively easy to snip the mainboard header off and solder the wires to a decent sized connector. Here’s a pic: http://bit.ly/dmcuRG

    What about digital camera’s lcd screen?

  15. erak says:

    @hack-cough

    I have the same question. Have a couple of pentax optio displays just waiting for some action

  16. armando says:

    Do you know where i can find the nokia 2760 pinout ? ( for FBUS)
    I have a lot of old nokias to use on my hacks, but some (like 2760) doesn’t have the pinout on the internet.

    Thanks.

    I have the same question as someone asked above. how useful would a digital camera lcd be in such hacks? I currently have a screenfrom a hp photosmart 435. it has a small ribbon style connector. Anyone have any interesting ideas for such a thing? would love to make a fun project out of this thing.

    Can you tell me if you use LCD display froom Philips 960? I search specification to use it , but i don’t found anywere.

  21. nash211 says:

    wow that thing was Awesome!

    Great! can you share to everyone the diagram,
    who visit this site

    That thing can be turn into LCD googles ! ! !
    plz can you share about the diagram, thank you . . .

  22. ElectronicsHobby says:

    Is it possible to share information on Nokia 7210 Supernova LCD (seems it is 240 X 320) which has 24 bit connector?
