PAMS RAE–2 UIF Module BS2 Technical Documentation 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.
PAMS RAE–2 UIF Module BS2 Technical Documentation 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.
PAMS RAE–2 UIF Module BS2 Technical Documentation 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.
PAMS RAE–2 UIF Module BS2 Technical Documentation 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.
PAMS RAE–2 Technical Documentation UIF Module BS2 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.
