CMT LCD Display Circuit
The display circuit includes the LCD module BC2 and two capacitors. The LCD module uses COG (Chip On Glass) technology. The connection method for chip on the glass is ACF, Adhesive Conductive Film. The LCD module is electrically connected to UI board with gold wired elastomer. Two external capacitors are placed on UI PCB.
The display driver includes hw–reset, voltage tripler or quadrupler which depends on temperature, temperature compensating circuit and low pow­er control. The driver includes a 84x48 RAM memory which is used for storing display data. The driver does not include character generator ROM. One bit in RAM is mapped directly to one pixel on display.
Main characteristics of the CMT LCD display: – Display resolution: 84 x 48
– Viewing area: 34.96 x 23.50 mm – Dot size: 0.31 x 0.37 mm – Dot pitch: 0.345 x 0.405 mm – Display type: Transflective black and white FSTN

PDA LCD Display Circuit
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.
Main characteristics of the PDA LCD display: – Display resolution: 640 x 200
– Viewing area: 111.8 x 37.0 mm – Dot size: 0.16 x 0.16 mm – Dot pitch: 0.17 x 0.17 mm – Display type: Transflective black and white FSTN
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.

Backlighting Circuit of CMT LCD And Keyboard
An electroluminescent (EL) panel is used for CMT LCD and keyboard backlighting. Electrically it can be considered as a capacitor. An inverter circuit is used to generate the high voltage AC to drive the EL panel. The inverter can be divided into two sections: power converter section and lamp driver section.
The power converter section employs a switch–mode converter to gener­ate a voltage of maximum 90V. This voltage is connected to the EL panel through the lamp driver section, which changes the polarity of the output pins at a frequency that is set by one external resistor. Since the switch– mode converter’s output is regulated to 90 volts at maximum, it is pos­sible to achieve almost constant illuminance from the EL panel throughout the battery voltage range.
Connection between the EL panel and the PCB is a simple pressure con­tact. The frame of the CMT display module has two springs that press the EL panel against the pads on the PCB.
NOTE: The EL driver output voltage between pins 6 and 7 is over 150 V peak–to–peak. When making measurements, be sure that measuring equipment like oscilloscope, probe etc. have high enough voltage rating. There is no risk of getting a harmful or fatal electric shock due to low cur­rent driving capability of the inverter.

PDA LCD Backlighting Circuit
Electroluminescent (EL) panel is used for PDA LCD backlighting. The cir­cuit is similar to the CMT keyboard and the display backlighting circuit, only some component values are different.
PDA display frame presses the EL panel contacts against the pads on PCB.
NOTE: The EL driver output voltage between pins 6 and 7 is over 150 V peak–to–peak. When making measurements, be sure that measuring equipment like oscilloscope, probe etc. have high enough voltage rating. There is no risk of getting a harmful or fatal electric shock due to low cur­rent driving capability of the inverter.

PDA Function Keyboard And CMT Keyboard Circuit
There are 5 columns and 4 rows in the CMT keyboard matrix and 2 rows and 4 columns in the PDA function keyboard matrix. The power key is connected to the CMT row 0 through a diode, that prevents the POWER­KEYx line from being pulled down when the other keys are scanned. A normal keyboard scanning is used to read both matrices.
