Post by thread:[PICLIST] [EN]: Thoughts on Serial Graphic LCDs

Hello once again everyone! I’ve managed to find the pinouts for the Nokia 5190 lcd…. Now, what to make of them I’m a bit lost… Brief description: Pin 1 à VL (supply voltage 2.7-2.85 volts) Pin 2 à SCLK (serial clock input 0 – 4MHz @ 2.7V) Pin 3 à SDA (Serial Data Input, low = 0V high = 2.7V) Pin 4 à LCDCDX (Control / Display data flag input, low = control, high = data) Pin 5 à LCDCSX (Chip Select input, low = active) Pin6 à OSC (External clock for LCD 30.4-33.6kHz @2.7V) Pin 7 à UDGND (Ground) Pin 8 à VOUT (DC/DC voltage converter output, 9V max) Pin 9 à LCDRSTX (Reset, low = active) Ok, that being said, here is some other info: The display circuit includes LCD module GD40 and two capacitors. The module uses chip on glass. The display driver (LP-7366-A) includes hw-reset, voltage tripler or quadrupler (depends on temperature), temp compensating circuit and low power control. The driver includes 84X48 RAM memory and does not include CG-ROM. One bit RAM = 1 pixel. That’s all I have… now, who manufactures it? Couldn’t tell you… what is the display resolution? 84 x 48? I figure you pump the data into the driver RAM serially... but I'm wondering the purpose of LCDCDX. Are there different control commands? I've done an extensive search on the net to see if there are similar displays that employ similar schemes but to no avail. Anyone have any insight on this? I'm thinking it would make for a great PIC project once it's all sorted out. Thanks in advance!
