25 Liquid Crystal Display (LCD)

LCD requirements for Smartphone : 

26 LCD requirements for Smartphone 1. Viewing purposes/coloured display Email and web browsing Applications Display cheapest call costs and bills 2. Touch Panel Interface Alternative to a “mouse” Dial without keypad

Overview of LCD Technology : 

27 Overview of LCD Technology

LCD Models Considered: : 

28 LCD Models Considered: 1. Sharp TFT LCD touchscreen: Model: “LQ05703DC02” 320x240 QVGA cost: US$455.05 2. Hitachi LCD touchscreen: Model: “SP10Q003-T” 320X240 STN Colour graphic display cost: AU$261.75 Direct interface from “DragonBall MX1” Not Chosen: Too expensive and hard to get. Chosen: Much cheaper than Sharp and availability from many distributors. Reason: Need only an inexpensive LCD as our group intends to use it for proof of design and it interfaces with our microprocessor

43 Connectivity and External Devices

Connectivity Options : 

44 Connectivity Options Need to allow connectivity for external I/O devices such as keyboards, printers, scanners etc Also need to allow for network/LAN connectivity Trade-off between flexibility and complexity/price

External I/O Devices :

Connectivity Design Challenges : 

49 Connectivity Design Challenges Ideally would like to directly support as many network and I/O devices/options as possible External devices such as cable/ADSL modems take up physical desk space

Connectivity Design Challenges (cont) : 

50 Connectivity Design Challenges (cont) Writing/porting device drivers for external devices is also a problem However, for cost and complexity reasons, convenient features like in built ADSL are not going to be supported
