iPhone
Definition:
The iPhone is a smart phone created by Apple that combines a mobile phone with an iPod. With an iPhone you can also browse the Internet, manage your email, manage your daily appointments, check stock prices, check the weather, watch YouTube videos and more. The iPhone looks different than a traditional mobile phone due to the fact that it relies on a touch-screen interface rather than traditional buttons.

LCD
LCD stands for liquid crystal display and is a technology used in screens for monitors, televisions and other small electronic devices. LCD technology is popular in high definition televisions mainly because they are considered good for brightly lit rooms due to their minimal reflections. Some people report a "screen door" effect on LCD televisions meaning they can see spacing between individuals pixels on the screen if they get close enough to the television. LCD competes with DLP and plasma technologies.
