Apple devices were long known for having some of the highest-quality LCD screens, enhanced by retina displays and mini-LED backlighting. The company has made a phased transition to OLED, starting with Apple Watch, then iPhone and iPad models, with MacBook Pro next in line, followed by MacBook Air and iMac.

OLED screens differ from LCD as each pixel directly illuminates using organic compounds, enabling vibrant colors and deep blacks. However, uneven pixel wear from static content at high brightness can cause permanent ghost images known as burn-in. Panels compensate by delivering extra power to weaker pixels, potentially accelerating degradation.

Burn-in is almost certainly not a concern for MacBooks for four reasons. First, laptop usage patterns differ from static displays like airport monitors — menu bars and docks are regularly hidden by full-screen apps. Second, modern OLED panels are far more robust; iPhone home screen icons remain unchanged for years without complaints. Third, laptops rarely run at maximum brightness for extended periods. Finally, Apple will use tandem OLED panels stacking two layers, halving power per pixel and significantly reducing energy stress that causes degradation.
