The touch screen is a screen 9.7 inches which uses liquid crystal display technology (LCD) and are made of durable glass resists scratches. Like the iPhone, the iPad is designed to be controlled by bare fingers, rather than gloves and special pens that prevent electrical conductivity. The screen responds to two other sensors: an ambient light sensor to adjust screen brightness and a epitachynometro who feels the orientation of the iPad and allows the user to change the way in which keeps the device, selecting between horizontal or vertical orientation. Unlike the iPhone and iPod touch, the iPad supports screen rotation for any corners (in 90 ° increments), which means that the device is operating is not ' up ' or ' down ' regardless of how he keeps the user, only the position of the button does not change.
The iPad can use the Wi-Fi network to find its location on Google Maps. Version 3G has A-GPS while both versions have a digital compass.
The iPad has a button below the display that returns the user to the main menu and three plastic buttons on the sides: wake/sleep, volume up/down, and screen rotation lock. The last, reportedly, there to prevent accidental screen rotation when the user reclines.
The back part of the Wi-Fi version consists of aluminium black plastic buttons. The Wi-Fi version + 3G has a black plastic surface at the top to increase the intensity of the signal received from the HSDPA network.
