A laptop's screen is the main display for the user to read data.
The screen is where information is displayed for the user of a laptop. If the screen is cracked or otherwise damaged due to an unfortunate accident, you'll have to get a new one. There are a number of components that go into the screen, and users should know about these before they do anything.
Screen
When most people think of a laptop screen, they think of the entirety of the upper portion of the laptop. This is different from the actual screen that displays information for the user. The screen is a thin, liquid-crystal display held in place by other components. The actual screen is a thin sheet with a connector along the bottom. The connector provides ports for video input that allow the screen to correctly display images for the user. While only a part of the upper portion of the laptop, the actual screen is only the thin, LCD sheet.
Frame
The second part of a laptop's "screen" (the top portion of the laptop) is the frame. The laptop's frame is what holds the screen in place; it covers the sides and back so that the screen doesn't get damaged. The frame provides solidity, a backing, and protection for the relatively fragile computer screen all at once.
Hardware
The frame holds the screen, but the frame comes in several parts. What holds the frame together--and thus gives it the ability to keep your screen whole--is the hardware. There are four screws at the corners of the laptop screen, and these screws hold the frame together and keep the screen in place. These screws are covered by rubber nipples that stop the screws from scratching or damaging any parts of the laptop once it's closed, and they also help provide an extra layer of buffer between the screen and the keyboard.
