M4 MacBook Professional. Picture supply: Apple
A show analyst shared that Apple has shifted from conventional purple KSF phosphor movie to quantum dot movie within the newest MacBook Professional fashions with M4.
Quantum dot expertise is not new, actually, Apple has been investigating its use in shows since no less than 2014. By changing the layer of phosphor movie with nanocrystals constructed from semiconductor materials known as quantum dots, shows can show brighter and extra vibrant colours.
Based on DSCC analyst Ross Younger in a publish on X, Apple did not beforehand use quantum dot movie due to its use of the poisonous materials cadmium. Nonetheless, that has modified with the discharge of the MacBook Professional with M4.
The most recent cadmium-free quantum dot movies have reportedly proven improved coloration and movement efficiency — even surpassing earlier movies with cadmium. This has allowed Apple to shift to the superior movie from purple KSF phosphor.
Large Apple show information, they’ve adopted quantum dots for the primary time. The most recent MacBook Professional’s (M4) use a quantum dot (QD) movie moderately than a purple KSF phosphor movie.
Prior to now, Apple went with the KSF resolution on account of higher effectivity and lack of cadmium (Cd), however the pic.twitter.com/5olq9lEHs9

Usually talking, customers might not discover the distinction except viewing very particular examples meant to emphasise the impact. Nonetheless, the expertise does make the show higher general.
Quantum dots are man-made nanocrystals that exhibit quantum mechanical traits. They emit mild isotropically after being excited by the backlight.
The impact brings the LED show nearer to the colour vary and efficiency of OLED. Nonetheless, that does not imply MacBook Professional would not profit from shifting to OLED in a future mannequin.
What it does imply is that Apple might wish to proceed to make use of the mini-LED backlit panels for some time longer whereas OLED panel costs proceed to drop. Earlier rumors recommend 2026 for Apple’s first OLED MacBook Professional.
