OVERVIEW: Digital Section
1.6.12 LCD Circuit
The LCD circuit consists of a full-graphics, liquid-crystal display module that has a
resolution of
240RGBx320pixels, 262K colors. The data lines for the display module are
connected to RGB 6:6:6 (18 bits) and control interface from the IPU section of the Zeus
processor. The display module booster voltage is powered by V1 (2.775 V), the I/O is
powered by SW2 (1 .875 V). The display module connects to the flip PCB through a 54-pin
connector and the flip PCB connects to keypad flex through a 60-pin connector. Then to the
keypad flex through a 80-pin connector which in turn connects to the main.
1.6.13 CMOS 2.0 Mega-pixel Focus Camera
The camera is a 2-Megapixel, color CMOS image sensor with Bayer (Green, Red, Green,
and Blue) patter filter and no auto focus features. This device provides a finished image
at up to 15fps (frames per second) image data at 1200 X 1600 resolutions and up to 320 x
240 resolutions to enable video clip capture. It resides on the camera flex circuit
connecting to Flippcb through the 30-pin connector.
Control of the camera settings from Zeus is via I2C serial interface, using 8bits data
transfers.
