- akvadrako 8y agoYou need brightness too. I have both e-ink and MBP screens - both work in the sun.
- akvadrako 8y agoJust to give some numbers: e-ink has a contrast ratio of about 20:1 with 40% reflectance. A sunny day is 10000 - 30000 nits, giving at least 4000 nits of brightness. The 2018 MPB screen has a 1500:1 contrast ratio and about 500 nits of brightness. So if e-ink is really easier to read in the sun (which I think) then brightness is much more important.
- hestipod 8y agoIt's not that simple. I cannot explain the physics/physiology of it with any authority, but as someone who suffers from severe strain and headaches with LED (and some CCFL) backlighting I can you it's feeling like something to do with direct vs reflected lighting vs some brightness or contrast metric. Looking at E-Ink or print on paper in a variety if lighting is generally fine (as long as it's bright enough for a normal person to read..obv too dark and different strain occurs)...but an LED backlit LCD even on low settings (so maybe 10% of those 500 nits) results in problems. Stare at a lightbulb vs staring at a white wall that bulb is shining on for a simple illustration. I don't believe it's polarisation either since wearing polarized sunglasses doesn't result in strain and just like an LCD polarizes the light that reaches your eyes, so do the glasses.
