Display Circuit
The display circuit includes LCD module GD40 and two capacitors. The LCD module is
COG (Chip on Glass) technology. The connection method for chip on the glass is ACF,
Adhesive Conductive Film. The LCD module is connected to UI board with gold wired
elastomer. Capacitors are placed on UI PCB.
The display driver includes hw–reset, voltage tripler or quadrupler which depends on
temperature, temperature compensating circui t and low po wer control. Driver includes
84x48 RAM memory which is used when some elements are create on display. Elements
can be create with software. Driver doesn’t include CG–ROM. One bit in RAM is same as
one pixel on display.

Power Key
Micro switch is used as a power key on UI module. Circuitry includes micro switch and
two diodes which is needed for MAD interface. Power key is connected to CCONT. Power
switch is active in LOW state. The power key circuit can be seen from the Display Circuit
diagram. The power key is connected to ROW4.

Display
Backlighting is provided by LEDs, three LED on right and three on left side of display.
LEDs are compatible with CL270–YG and those are side illuminating. Light is on when

Speaker
The speaker is sealed to A–cover and UI PCB with silicon gasket. With that the frequency
response is more constant. Speaker needs 6pcs of 1.2mm holes under component for
leaking sound pressure into RF–section through UI module and 7pcs of 0.9mm holes left
corner of UIM to leak from RF–section back to up cavity of phone. RF–section between
UI module and engine acts like sound cage which is known. This gives better sound quality for the phone and it can be estimated in several environments.
Silicon gasket and speaker itself acts like water proofing elements in that area. Water
can come in speaker space between speaker and A–cover but not further from there into
the phone. On A–cover are three pieces of leaking holes which are not located top of the
speaker. The holes give better sound quality and are less sensitive for how well phone is
pressed against side of head.
