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 circuit and low power 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.

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 LIGHT–signal is in HIGH state.

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 Ultra and Santra 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 is 3pcs of leaking
holes which are not located top of the speaker. This holes gives better
sound quality and less sensitive for how well phone is pressed against of
head.
