What is the difference between LED and LCD screen in a MacBook Pro?

pitanje.Prva Good thing we have to clean up the idea that your MacBook or MacBook Pro has an LED screen, not LCD zaslon.LED refers only to the background of the screen, not the whole screen. There is a common misconception that the current models of MacBook and MacBook Pro do not use the LCD screen.

So, what is the deal? Well, until June 2007, Apple laptops use LCD screen that uses a cold-cathode fluorescent lamp as backlight.

Why would you need a background in the first place? Another good question - you're on a roll. LCD screen need a backlight because the screens themselves (liquid crystal display part) does not emit any light. To see what is on screen, you need a special light, which is located behind the glass LCD screen, to brighten things enough for you to view them.

joint MacBook and MacBook Pro notebook repair a damaged screen due to a fall that causes the backlight to stop working. You can usually tell if your backlight is damaged so as to turn your MacBook or MacBook Pro or PowerBook or iBook for that matter, if your screen looks dark, but you can still see things on the screen when you shine a flashlight on it, chances are your screen is damaged or not working backlight.

In 2007, Apple (and a bunch of other companies) decided that CCFL backlights are bad and they had to go. They were full of mercury (bad), they use up a lot of power (bad) and broke quite easily (very bad ).

So, enter stage right, the LED backlights drive in June 2007. Since that time, all Apple laptops have used back-lit LCD screen with LED backlight based. This helped to increase battery run times, increased reliability and help the environment all at the same time. All is well.

technicians still see the LED backlit MacBook and MacBook Pro systems that come every day to repair. Although the LED is more reliable and less fragile than CCFL, they still break when dropped hard enough.

Customers often ask, if only the backlight can be replaced on the LCD screen, and while it is true that you can replace just the backlight of LCD panels in many parts and labor costs are much lower than replacing the entire screen. In addition, the vast majority of the screen many times as additional damages, either alone or on the LCD screen on the housing on a MacBook or MacBook Pro.
