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 hw­reset, 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 CG­ROM. One bit in RAM is same as one pixel on display. PWRXON

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 on page 8.The power key is connected to ROW4.

Speaker
The speaker is sealed to A­cover 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 RF­section through UI module and 7pcs of 0.9mm holes left corner of UIM to leak from RF­section back to up cavity of phone. RF­section 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 A­cover but not further from there into the phone. On A­cover 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.
