I was wondering what the difference is between the screen, lcd and digitizer on the iphone 2g, and also how they look like?

digitizer is small attached to the glass that detects touch
screen is the outer glass that does nothingbut protect everything
lcd is what displays the actual picture

The screen is the glass on the front of the iPhone that you touch. It has the opening of the ear speaker at the top, and the opening for the home button at the bottom. It is real glass, is what usually cracks when you drop an iPhone. It looks like the entire front of an iPhone. It is just over half a millimeter (0.6 - 0.7 mm) thick clear glass with the top and bottom areas painted black.
The next layer is a thick layer of adhesive which bonds the front glass to the digitizer.
The digitizer is glass and interprets your finger touch movements so you can use the iPhone. The digitizer is just a bit larger in area than the picture size, you see when you use the iPhone.
The third component going in, is the LCD which is the video display screen, this displays the picture you see. The LCD size is nearly the size of the picture you see.
If an iPhone has window pane cracks, then front glass screen is broken.
If an iPhone does not respond to finger touch, then the digitizer is broken.
If the picture quality is bad, or areas of the picture is bad, then the LCD is damaged.
