Product Info
Color QVGA 2.3" 320x240
sku: LCD-08843
Replacement: None. There is no direct replacement for this item. This page is for reference only.
Description: This is a compact 2.3" diagonal color 320x240 pixel QVGA screen found out the inside of many cellular flip phones. These are meant to be deeply embedded, but because of the wonderful economies of scale, we can offer them for very low-cost.
The ribbon connector is 33pin with 0.8mm pitch. Comes with small adhesive backing on ribbon connector.
You can actually see through the glass. Unit does not come with a backlight, but it does mount very nicely to a specially designed backlight related below. The ribbon folds around the back of the backlight frame and has a cut-out in the ribbon for our smaller 1.1" QVGA display.
Features:
- Transmissive TFT
- 34x45mm active area
- 320x240 RGB pixel
- 262k color
- 18-bit parallel data interface
- Driver IC HD66790
Documents:
- Drawing and pinout
- Datasheet for HD66790 Note typo on page 23: Power Color 1 register address is R00h, not R01h as stated in the datasheet.

I suspect I will end up paying much more for the connector than the LCD itself, at the crazy price you're offering it.
I spent 2hrs looking - Nearest was 32 way
SODIMM skts are 0.8mm BTW.
0.8mm is solderable. At $1 you can trash a few!
Where is the HD66970 datasheet ? Links above look similar tho.
Anyone know what phone these were for? - poking around a working unit would help in the absence of the datasheet
That's not an FFC connector - it's a 2-part board-to-board connector, but might work at a pinch if you packed out the thickness.
do i need datasheets for HD66782,HD66790 because here are only links for HD66781, HD66789.

which is closer (34 pins), but I don't know where to get one at. You'd probably have to buy 10K of them no doubt.
Maybe the guys from SFE know something?
some help would be nice :D
The only info I've found on the HD66790 so far looks bad. It's described as a RAM less controller and the system example shows it connected to a CPU via a "display controller processor" and external ram for the display.
Doesn't look like the easiest setup to replicate with an embedded micro!

I suspect it's something that never got into production. I spent an evening looking for a phone with the right permutation of resolutions & came up blank. The wide connector pitch suggests this isn't from a latest-generation device - e.g. Ipod and NDS LCDs use 0.3mm pitch.
There are a few variants of the suffix - a lot of hits for the -F03 variant, so data should be findable for that - obviously it may use a different controller.
Maybe a useful lead for someone with time to do some hunting...
I don't think so - zebras are only used for direct-to-glass connection, and the resistance would likely be too high for the supply to a controller-on-glass display. The termination style on the backlight is identical - you frequently see these soldered to the main flex on other displays.
Looks to be a Samsung product.
Now that I've put my foot in my mouth, I'll let you know how my own attempt goes.
- Looks like this part is much more closely related to the HD66781 than to the HD66789.
- The part has no embedded RAM. There *might* be some on the module but I haven't gotten mine to look for it.
I'm going to try the Digikey 30 pin connector. I'll let everyone know how it works.
But since I can't post there yet...
Note that there's a comment on the page for the smaller display that links to a datasheet for a module using the HD66782. It contains the initialization sequence.
It's interesting that the connectors for the main and sub displays of these sparkfun modules are identical, suggesting that the operating modes are very similiar.
