Hi,

I found a cheap OLED display on ebay
it comes with the datasheet

http://www.egochina.net.cn/e-shop/ebay/Datasheet/FH23-611S-0.3SHW.pdf

it's not clear if the S6E63D6 driver chip comes with it but I think so because there are not many pins

it comes with the connector and there is an optional breakout board
I think at that price (still twice as much as a comparable LCD display) it's a useable part for project (as opposed to sparkfun's 200$ oled display, I wouldn't throw that away on permanent installation)

I wonder if it can be used with an arduino, I don't know if you need to continually feed it an image of if you stop the clock the current image remains ?

it seems that this oled display is also sold by (and manufactured too)
by Pacer
http://www.pacer.co.uk/jkcm/Products/Categories/Displays/OLED%20Displays/Active%20Matrix%20OLED/

but the oled display I am refering too is made by "Chi Mei El Corporation", I am not sure if they are counterfeit Pace display, or if Pace buys them from Chi Mei  

also from the same guy there is a 7$ 1" 128x64 bichrome? OLED  (wow that's cheaper than a text LCD !!)

UG-2864AMBAG01
datasheet http://www.egochina.net.cn/e-shop/ebay/Datasheet/UG-2864AMBAG01.pdf

at that price I'm going to get one just for the fun of figuring it out !


on ebay just search oled touch   or even just oled , in increasing order of price including shipping you'll find them (there are surprisingly few of them)

links to actual ebay pages (will probably not work for long, sorry reader from the year 2022)

Forget about trying to drive a 320x240 colour display from an Arduino (any model). You don't have the RAM to provide the required frame buffer nor do you have the CPU Mhz to do anything other than service the LCD. You need to take a step up to something like one of these

You are looking for a touch shield.

OR

http://www.liquidware.com/shop/show/TSL/TouchShield+Slide

The plain LCD or OLED display requires so many added components and processing power you'd have a difficult time getting it running with a more powerful microcontroller. Both require highly specialized power supplies, a larger number of I/O ports and more.

The shield already has all of that.

If your looking for a 320x240 OLED touch screen module here's a great one by 4D Systems, serial interface with speaker,uSD slot and touchscreen, all supported by simple serial commands which I made a library for http:// http://shop.4dsystems.com.au/serial-display-modules/209-1004.html, it is only 2.4" they have a 2.8" but that's 320x280, along with some LCD modules that are cheaper. If your in the USA you can get it from here and save on shipping http://shop.littlepcbsolutions.com/product.sc?productId=28&categoryId=2.

Why do you need something this small? It's 20mm wide only. Yes, some things are cheap in China, where they're made. I saw a 2.8" 320*240 RGB color (probably 8 bit color) display with touch display (or not) for 60 RMB (USD 9.x) on a Chinese auction site. They don't ship overseas. I'm having a friend's friend bring a couple things over in a couple of weeks. Shipping is like USD15, too much for something around $30. Maybe next time I'll ask someone to bring some popular displays and share the savings on this board. I'm in US Midwest so shipping within US is probably not much. Just a thought.

well I was looking for a cheap display option for a "future undefined project"

at those prices (140$-200$+ship) it's too expensive to use in a throwaway project

but thanks to  Andy Brown
that 53$CAD+ship ARM9 board is interesting
I believe some ARM platform is going to be the prefered upgrade path from arduino (with maybe the xmega as an intermediate step) as soon as the developpement environments catch up with arduino's IDE's user friendliness

right now I think friendlyARM + Micro2440 is the cheapest QVGA color OLED solution

I am assuming that there are no cheap single chip framebuffers (or is it call a ramdac ?) we can use to generate VGA or NTSC from an arduino right ? (because you can spend a minute drawing a frame if you want if the signal generation is done outside the mcu), is that correct ?

That is the route I'm going down for my project that uses a 320x240 LCD. Develop on the Micro SDK board with all those IO breakout interfaces and when complete deploy the tiny STAMP board with just the parts I need. Running google Android on it provides you with all the graphics libraries you need to create a modern UI. Where did you see the micro for 53 CAD? That's a very good price.

That, in a nutshell, is the problem. The Arduino MCU's are just not designed to be driving devices that need so much data so fast.
