Get extra from Twilight
1) Bed studying: Twilight is extra nice on the eyes for night time studying. Especially because it is ready to decrease the display screen backlight far under the power of the backligt controls in your display screen
2) AMOLED screens: We have examined Twilight on an AMOLED display screen for five years with none signal of depletion or over-burning. If correctly configured Twilight causes much less mild emission (by enabling dimming) with extra equal mild distribution (darkish areas of the display screen such because the standing bar get tinted). This could actually improve your AMOLED display screen life time.
