Post subject:  Big LCD Nokia 9110 - pinouts
Hello all,
i found one old nokia communicator 9110. But it is totally dead, bcs it falls down into water. I decided to use the big lcd in my car mp3 player. I start looking for any information. I found whole schematics and service manual. And here is the pinout - for interested.
PIN Value info
1,2 16-22V bias voltage, on connector marked with triangle
3 14,7 - 20,3V intermediate bias voltage
4 13,5 - 18,6V intermediate bias voltage
5 2,6 - 3,3V intermediate bias voltage
6 1,3 - 1,7V intermediate bias voltage
7,8 GND
9 2,7 - 2,85 logic supply voltage
10 70-100Hz frame pulse, 75us long H
11 0-3,2MHz data clock
12 0 - 3,4kHz AC modulation
13 0 - 44,5kHz line pulse, 870ns long H
14 LCD ON L=off, H=on
15 data3 leftmost pixel
16 data2
17 data1
18 data0 rightmost pixel


for data levels:
min 2,75V
max 2,85V
0-0,5V blank
2,2 - 2,85V black


according to service scheme

The PDA LCD display circuit consists of the LCD display 4850049, logic
and bias voltage filtering capacitors and an NTC resistor that is used to
measure the temperature of the display. The voltage over the NTC is
read by PDA SW via Phaser power supply ASIC and the information is
used for contrast control of the display
The PDA LCD interface is a typical black–and–white LCD interface with
four data bits, pixel clock, line and frame pulse signals, AC modulation
signal and enable signal. Logic and bias voltages are supplied by the
Phaser power supply ASIC located in the PDA module

thats all folks, enjoy and raise your skills
i will try to control it
