I have been prototyping with a 4D systems 1.44" Display and it is fully functinal and works great. However, it is really expensive.
So I have been trying to locate another display to use in it's place. I originally chose the 1.8" TFT on adafruit because it has a fully functional library and it is only about $9.00. As I was preparing to buy one, it was brought to my attention that it might be a bit big for my enclosure (Thanks Crossroads!). Once I really took a look at it, I found that it is indeed too big. (Yes that is what she said!)
So now I am on the hunt for a 128x128 display. The chip on the adafruit display is the ST7735. I had to dig for a while but I found that ironically the 4D module also uses the ST7735. The major difference being that the 4D display has their proprietary Goldelox chip handling a lot of the detail and providing a pretty clean interface over serial.
So armed with this ammunition I have done a lot of searching for a 128x128 that uses the ST7735. While I have found a few China suppliers that have them, I am leery about purchasing direct. The advantage is that I can get 100 for $2.00 each.
I have also found a couple of other interesting option but this is where I get stuck and hope others have been through this to offer help and/or advice. And before anyone suggests it, the Nokia knockoff is not an option. They are more expensive and for all of their popularity, they actually have less support than the Adafruit ST7735. Plus there is too much confusion over which is which and what is what.
What i have found as another Chip the ILI9132 which I have seen several times referenced as a direct replacement for the ST7735 but cannot seem to confirm this.
I have also found the S6B3306 which seems to have at least a little support but still no sure thing.
Both of these were on EBay with free shipping for about $7.00
I am tempted to just start ordering displays until I get one I can use when I consider that my original BOM was using the 4D display at $30, I can afford to waste some money finding a solution. The problem is that they are all FFC and I would need an adapter for each or REALLY steady hands since none of them have the same number of pins on the FFC or the same pitch for that matter.
Any input would be welcome!
