- Nintendo 3DS uses an LCD screen
- LCD screens have three reflective layers
- each one reflects 'n causes glare
- with the 3DS XL, each a these three layers be specially treated
- this reduces reflectivity from 12% on the 3DS t' 3% on the 3DS XL
- there's also another screen cover that goes over the entire screen
- this be possible due t' the progress a technology 'n a drop in manufacturing costs
- the cost a anti-reflectivity coats be too high t' apply them in the past
- the current manufacturing process 'n cost balance make them possible t' use

“Anti-reflection has been a topic every time since the Game Boy Advance system, but most a the time we had t' give it up because a the cost.” - Satoru Iwata
