Displaying content on a normal alphanumeric display is very limited ,we have to be limited with the font size and we can't draw any graphics also. but convention Graphics lcd are really very expensive so here is the solution, you can use Nokia 1100 monochrome LCD to display your large font text and graphics . the reason behind using this LCD is ,it is really very cheap and can be powered with 3 volts supply. so it is really good for battery powered application.
Driver IC on this LCD panel is PCF8814 which even though has I2C protocol support - doesn't use it. Instead it uses simple bit-banging mechanism for communication.
however you can use almost any microcontroller (need a little bit extra circuit to work with mcu who doesn't support 3v) do display content on this LCD, may be that micro controller is PIC , AVR or MSP 430 ,8051 but in this demonstration we will be using Microchip PIC 18F458 Microcontroller.
The software program for this project will be written in C with MPLAB IDE , This LCD has a resolution of 96 x 65 pixels
