I recently mused about how theMac lineup has been the most compelling for a while , and one of the reasons is that Apple introduced worthwhile feature besides the cow chip upgrade to the M4 . For the M4 MacBook Pro , there ’s one more feature that Apple has n’t note at all .
harmonize todisplay expert Ross Young , Apple now uses a quantum Department of Transportation film in the MacBook Pro ’s Liquid Retina XDR display . This QD film replaces a KSF phosphor film ( also known as a minute - band cerise phosphor ) placed between the backlight and the display . The solvent is that the MacBook Pro ’s display creates a more consistent color gamut and “ better motion performance . ” There are also environmental welfare as Young points out :
Big Apple video display intelligence , they have adopted quantum dots for the first time . The latest MacBook Pro ’s ( M4 ) utilize a quantum Lucy in the sky with diamonds ( QD ) film rather than a violent KSF phosphor film .
In the past , Apple went with the KSF result due to well efficiency and lack of cadmium ( Cd ) , but the latest Cd - costless QD film are very efficient , feature as good or better color gamut and good motion performance .
QD film are often used on high - end TVs and display . So why the switch now ? Apple has n’t talked about this so it ’s bare guess , but establish on Young ’s post , it look that Apple was n’t satisfied with QD movie ’s old performance . Why did n’t Apple mention this alteration ? Most likely because it ’s the kind of under - the - hood change that wo n’t factor in much into a buying decision . But it ’s a notable modification that shows how Apple persist in to meliorate its high - end devices without raising costs .
It ’ll be interesting to see if Apple adopts QD film for the M4 MacBook Air , which uses an light-emitting diode display , or else of the mini - LED exhibit in the MacBook Pro . Reportssay that the new Air will be revealed in the outpouring of 2025 and it ’s expected to be nothing more than a check upgrade .
