Little, no name, 1.5 inch LCD photo key-chains are all over the place for practically nothing. Not too surprisingly these things do not vary much in the parts that they use, some flash ram, a little lipo battery and a 16 bit color LCD. Wanting to find a way to reuse that LCD [Simon] Has an excellent tutorial on how to reuse a FTM144D01N LCD with a ILITEK ILI9163 LCD driver for your electronic projects.
Two units were used, one was ripped apart and soldered to a home made breakout board, the other was kept intact so its logic could be sniffed out with an oscilloscope. A pin-out was quickly determined since these things typically use a 8 or 16 bit data bus. Then a driver library was put together for AVR micro controllers, which includes some basic shape drawing and a 5×8 font.
While you may not be lucky enough to get this exact LCD screen from your local bargain store, there are a lot of pointers in here to hopefully get you up and going. We will be trying our luck on a very similar screen this afternoon as these things do have a decent picture and fairly quick response times already packaged in a hand-held case.
