nuetron 64 Posted February 11, 2012 Share Posted February 11, 2012 Could someone tell me which pins are which on the back (the part that touches the pads on the pcb) of the 5110 LCD? I recently found one in a 10-yr-old cellphone, and can't figure it out. TIA, Nathan Quote Link to post Share on other sites

turd 31 Posted February 11, 2012 Share Posted February 11, 2012 I've got couple of those old phones. What works good is cutting down the circuit board so you have just what's under the LCD and soldering in fine wires into the vias. nuetron and oPossum 2 Quote Link to post Share on other sites

This also leaves the standard leds intact and inplace to light the screen. nuetron 1 Quote Link to post Share on other sites
nuetron 64 Posted February 11, 2012 Author Share Posted February 11, 2012 Thanks guys! Now I'll have a graphic LCD to play with! 2.7 to 3.3v? Sounds like I need a diode between it and my LP supply to drop the voltage. Quote Link to post Share on other sites
oPossum 1,083 Posted February 11, 2012 Share Posted February 11, 2012 They seem to tolerate 3.6 volts without any problems. That is well under the absolute max for the PCD8544 controller. nuetron 1 Quote Link to post Share on other sites

nuetron 64 Posted February 25, 2012 Author Share Posted February 25, 2012 How much current can the LCD charge-pump multiplier provide? Quote Link to post Share on other sites
turd 31 Posted February 25, 2012 Share Posted February 25, 2012 Mine puts out 8.2V but at not even a milliamp. If you short it with a 10K resistor the LCD goes out. Quote Link to post Share on other sites
oPossum 1,083 Posted February 25, 2012 Share Posted February 25, 2012 Just enough for the LCD, and no more. It is not intended to power anything external. It has a pin on the LCD module so you can connect a 100 nF cap that is required for stable and reliable operation. Quote Link to post Share on other sites
