Preview at WWDC likely in June, followed by September launch.
iPad Mini 4 Display Has Improved Color Gamut and Lower Reflectance
iPad mini 4 also has a record-low 2% screen reflectance, compared to 6.5% reflectance for the iPad mini 3 and and 9% reflectance for the original iPad mini. This gives the iPad mini 4 a contrasting rating in high ambient light of 225, which in layman's terms means the tablet has improved readability in real-world viewing conditions.
DisplayMate Technologies President Ray Soneira:
But in terms of real-world viewing conditions, the record low 2.0% screen Reflectance actually makes a bigger visual difference for the image colors and image contrast that you actually see because ambient light washes out and degrades the displayed images and reduces screen readability - so [the iPad mini 4's] record low Reflectance actually makes a bigger difference!DisplayMate says the iPad mini 4 has between 2.5x and 3.5x higher contrast in ambient light than the iPad mini 3 and most other tablets, which mainly fall in the range of 5.0% to 6.5% screen reflectance. iPad Air 2 was the previous record holder with 2.5% screen reflectance, but the iPad mini 4 was 36% better per this test.
DisplayMate will provide in-depth analysis of the iPad mini 4 display when the iPad Pro launches in November.
