Hi all,
I asked here about small LCDs with COG controllers recently, and had some interesting suggestions, but nothing that directly led me to being able to prototype my project. After investigating the matter a lot deeper, it seems like my only option is to repurpose a cellphone display. I'm aware of numerous projects that involve monochrome LCMs from different phones. But I need one grayscale LCD and one color LCD. I need at least 4 grays, preferably 8. Not only are all the projects I can find monochrome, but most of them use European phones, and it's quite difficult to cross-reference the numbers with equivalent U.S. models.
I don't mind spending a couple of hundred dollars on these displays if need be - so it's quite acceptable for me to have to buy and junk a brand-new cellphone. But I need to be *sure* that I can use the LCD.
Can anyone point me to a homebrew project that will lead me to suitable cellphone LCDs available in North America? To reiterate my needs:
1 grayscale STN LCD ~1" diag or smaller, 96x64 or so is fine (anything down to about 48x48 is probably OK). Minimum 4 gray levels.1 CSTN LCD, at least 2 bits per color component, ~1" diag or smaller, same kind of resolution requirement as above. This is more important than the grayscale one, actually.
LCD must have integrated controller. Anything much bigger than about 1.5" diagonal is too large.
I've found numerous parts that would suit me fine, but they're just not available as samples. I've also found plenty of sites selling replacement LCDs for cellphones, but no datasheets for those parts. So I'm kind of between a rock and a hard place.
