3.2.6.2 APX 7000/ APX 7000XE LCD Display Modules

3.2.6.2.1 QVGA

The APX 7000/ APX 7000XE radio can have up to 2 displays (QVGA and FSTN) depending upon

the particular feature set and radio model ordered. The main Transflective 2.2" color display is a

QVGA (240 x RGB x 320) active matrix TFT (Thin Film Transistor) LCD. This display is part of the

back chassis subassembly with interconnection passing through the keypad as shown in

3-43. The QVGA (Part no. 72012006001 and 7275620B01) display consists of 2 interfaces for

communication. It uses a 3-wire SPI bus (LCD_CLK, LCD_DIN, and LCD_CS) to initialize and

program all the internal LCD driver register settings, and an 18-bit RGB interface (I/F) to send the

data/image to the display. Each pixel is 18 bits and sent in parallel across the RGB I/F to produce

262 k color capabilities.
