Anyone in the market for a small tablet may be taking a look at the Nexus 7 2nd gen, the Kindle Fire HDX or the Apple iPad Mini 2. All of the tablets recently got put against each other and surprisingly the iPad Mini came out at the bottom of the pile. It seems that that image retention isn't offered with the Apple iPad Mini 2 and along with this there haven't been any changes to the colour gamut since last year's offering from Apple.
There is an indium-gallium-zinc oxide display with the Apple iPad Mini, while the Nexus 7 comes with a poly silicon display and the Kindle Fire has the Quantum dots. Dr Ray Soneria did 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." He said that the largest resolution and ppi was seen with the Apple iPad Mini 2 but the tablet has just 63% of the colour gamut that was on the Apple iPad Mini from last year.
Meanwhile the Kindle Fire HD and the Nexus 7 both had 100% scores; this was the same as that of the Apple iPad 3 and iPad 4. The Doctor said:
"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 pointed out that the Apple iPad Mini 2 didn't have the same quality as seen on other devices from Apple, such as the Apple iPad Air. The Air has full SRGB cover and this is the same as seen with the Apple MacBook Pro and the Apple iMac. It was also said that the display is reflective and brightness was 30% lower than on the Nexus 7. Therefore if you like to watch movies on your tablet you would be a lot better off with the Kindle Fire HDX or the Nexus 7.
