We have recently seen a comparison made between the Kindle Fire HDX, Nexus 7 2 and the Apple iPad Mini 2. iOS fans may be shocked to hear that the iPad Mini 2 lost out to the other two and this was mainly down to the fact that Apple hasn’t changed the colour gamut since the original iPad Mini and the tablet doesn’t have image retention.
On the Apple iPad Mini 2 there is a display of Indium-Gallium-Zinc, the Nexus 7 2 has a display of polysilicon and there is a Quantum dot display on the Kindle Fire HDX. Dr Ray Soneria undertook tests for “Objective Picture Quality, Absolute Color Accuracy, Screen Reflectance, High Ambient Light Display Performance, Peak Brightness, Contrast Ratio, Image Contrast Accuracy, Viewing Angle Performance, Display Power, and Battery Running Time.”
While the Apple iPad Mini 2 offers the largest resolution along with having the highest ppi, the colour gamut came in at just 63%, which was what was on the first Apple iPad Mini.
The Kindle Fire HDX along with the Nexus 7 2 had 100% colour gamut, which is what is on the Apple iPad 3 and 4. Dr Soneria reached the conclusion that:
“The new Google Nexus 7 has a very impressive display that uses the highest performance LCDs with Low Temperature Poly Silicon LTPS. The very high efficiency LTPS technology allows the new Nexus 7 display to provide a full 100 percent Color Gamut and at the same time produce the brightest Tablet display that we have measured so far in this Shoot-Out series.
Most impressive of all is the Kindle fire HDX 7 – the first Tablet display to use super high technology Quantum Dots, which produce highly saturated primary colors that are similar to those produced by OLED displays. They not only significantly increase the Color Gamut to 100 percent but also improve the power efficiency at the same time. Quantum Dots are going to revolutionize LCDs for the next 5+ years.
And finally… the iPad mini with Retina Display unfortunately comes in with a distant 3rd place finish behind the innovative displays on the Kindle Fire HDX 7 and new Nexus 7 because it still has the same small 63 percent Color Gamut as the original iPad mini and even older iPad 2.
That is inexcusable for a current generation premium Tablet. The big differences in Color Gamut between the Kindle Fire HDX 7 and Nexus 7 and the much smaller 63 percent Gamut in the iPad mini Retina Display were quite obvious and easy to see in the side-by-side Viewing Tests.”
CNET also said that the Apple iPad Mini 2 quality isn’t anywhere as good as that of the Apple iPad Air. This had the SRGB of the MacBook and iMac Pro. The Apple iPad Mini 2 also showed deviations of the blue, red and magenta. The display was reflective and there was 30% less light than what was seen on the Nexus 7 2nd gen. It was said that for those who wanted to watch films on the tablet the Nexus 7 2 or the Kindle Fire HDX was the best.
