Apple original MacBook screen vs third-party screen

You don’t need to make a decision between using an Apple original screen or a cheaper third-party screen. We ONLY use original screen !

the same background and set the brightness to maximum.

The screen on the left is an Apple original screen; right -hand side is a aftermarket  screen purchased online.

A MacBook screen consists of two major components, an LCD panel and   LED  backlights. The LCD panel creates the image. The LED lights illuminate the image from behind the LCD panel. There are significant differences between an original Apple screen and a third-party screen as outlined here:

  1.  Backlight purity. Apple uses high-quality LEDs as backlight sources. The backlight is pure white. On the other hand, the backlight of the third-party screen is bluish. The bluish backlight degrades the vivid picture dramatically.
  2.  Backlight brightness. Even after many years, Apple’s high-quality LEDs provide brighter lights and remain near the same brightness level. Low-quality LEDs not only produce bluish light but also have brightness degradation problems. The brightness of some third-party screens may only maintain half of the original brightness level after a year of use.
  3. Photo sharpness. The Apple original screen produces a much sharper image thanks to the high quality of the LCD panel, as you can see on the left -hand side of the above photo.

 

same thing happened  on the  iPhone screen as well!
