Lead researcher Jason Heikenfeld says the display can create 1,000 colors, reflects about 55
percent of ambient light and could reach 85 percent reflectivity.
Today's commercial readers, which use a different screen technology, reflect about 40
percent of ambient light and become even dimmer when showing color images because filters must be added.

Right now the iPads are the unrivaled record holders for display performance in
ambient light as a result
of their record low screen Reflectance
of 1.7 to 2.6
percent, significantly lower than the 4.5 to 6.5
percent Reflectance currently found in all other current competing Tablets and Smartphones.
So in addition to washed out, under saturated and distorted colors (red tomatoes, fire trucks, and Coke cans look a bit orange rather than deep red, for example) it continues with a moderately high screen Reflectance
of 6.5
percent, almost triple that
of its favored littermate, which further washes out its image colors in
ambient light...
On the other hand, the iPad mini 3 lacks the anti-reflection coating and has an air gap beneath the cover glass, which results in a moderately high screen Reflectance
of 6.5
percent, almost triple that
of iPad Air 2, so its Contrast Rating for High
Ambient Light is 61, which further washes out its image colors in ambient l

Together with its low 5.7
percent screen Reflectance it has a Contrast Rating for High
Ambient Light of 120, by far the largest we have ever measured for a Tablet.
As discussed below, the record low screen Reflectance
of 4.7
percent for the Galaxy Tab S further improves its effective Screen Brightness in high
Ambient Light.
Among all existing Tablets
of any size, the iPad mini 4 takes first place and breaks performance records in many
of the most important test categories including: lowest screen Reflectance (2.0
percent), highest contrast rating in high
ambient light (225), a near perfect log - straight intensity scale and gamma
of 2.22, and the highest absolute color accuracy (average / maximum color errors
of 1.9 and 4.2 JNCD — tied for first place with the Microsoft Surface Pro 4).
Right now the iPads are the unrivaled record holders for display performance in
ambient light as a result
of their record low screen reflectance
of 2.0 to 2.6
percent, significantly lower than the 4.5 to 6.5
percent reflectance currently found in all other current competing tablets.
