Programming the Nokia 6610 Mobile Phone LCD Display




Nowadays, phones are switched so fast that we do not even notice what we throw into the trash.
The best example is the 2G generation color display cameras. Many follow the fashion they feel uncomfortable about having no camera in their phones …
I first met Youtube on this strange way of recycling mobile phones. They are normally powered by microcontrollers, but for me, the printer port of the PC was necessary.

Display pinouts:

Pin Function

1 VLogic
2 #Reset display reset (active low)
3 SDIn serial Display Data
4 SClk serial data clock
5 #Cs display select (active low)
6 VLcd
7 Nc
8 Gnd
9 Vled+ backlight LED
10 Vled- backlight LED


LPT to LCD pinout:

1 VCC +3,3V

6 Q4 2 RES External Reset -active low

7 Q5 3 DATA serial data input

8 Q6 4 CLK serial clock

9 Q7 5 -CS Chip Enable input -active low

6 VCC +3,3V – Digital supply

7 N.C.

18-25 8 GND 0V

9 VLED-

10 VLED+

For the sake of reconstruc- tion, I will also attach the circuit diagrams and the SOURCE CODE of the operating program !!! (Running with Turbo Pascal or other freeware Pascal). Please to run under DOS or Win95/98! So if anyone knows this programming language, you can easily use it for your own purposes. Switching:
The display generates the voltage from the current generator to provide a constant brightness to the display regardless of the input voltage.
The 33 Ohm resistor can be used to set the current (0.6Volt / 33Ohm = 18.2mA). 0.6Volt is the transistor UBE voltage.


The supply requires a stable 5Volt and a voltage of 8-15V. You can even connect directly to your computer using + 5V and + 12Vol.
The display needs power around 3.3Volt. I solved this from the 5Volt to 3b by connecting a 1N4148 diode. The LPT (printer) port is connected to the D4 ... D7 data lines, at each location 10k resistors are in series so that the display can be more easily protected against overvoltage due to less current flow.



The pin is connected to the display with the adapter below, as the display's factory connector is 1/4 raster and no wire can be soldered,
So you can change the display.

With my own program, I hit the Pascal characters set so I can write this on the display
