All about Display: mobile phones in the laboratory: How We Tested the c’t smartphone displays; How LCDs and OLED displays?; What do manufacturers against specular phone screen?; iPhone 5 touch screen twice as fast as with Android; Forget ‘Full-HD: LG builds qHD display for mobile phones

end of October, Apple has the iPad mini donated a retina display. The new display is 2048 × 1536 pixels and is achieved with a diagonal of 7.9 inches, a pixel density of 326 ppi. This is the sharpness of the display on the same level as the iPhone 5S. The Android competition out there, however, no nakedness: The Nexus 7 brings it with 1920 × 1200 pixels at 7.0 inches at 323 ppi only minimally worse. The same data are for Amazon Kindle Fire 7 HDX Its big brother – Kindle Fire HDX 8.9 – leads the field by the way with 2560 × 1600 pixels at 8.9 inches and so rich 339 ppi

But how it looks behind the bare facts? Our colleagues from c’t tested the tablet quartet from Nexus 7, iPad mini (2014) and Amazon Kindle Fire 7 HDX and HDX 8 in the laboratory through its paces. How and what is being tested, says the video below.

Thus, the c’t smartphone and tablet displays tests in the laboratory.

contrast

What is the difference between black and white on the display? The contrast answered this question and thus permits a conclusion to the brilliance of the screen.

distance at the top of the Kindle Fire HDX 7 is in this discipline with a brightness ratio of 1670:1, closely followed by the more Amazon Kindle Fire Brother HDX 8 with 1311:1. Bronze gets the Retina iPad mini with 979:1, the flower pot made of paper mache goes to the Google Nexus 7 with 892:1.

color reproduction

Besides the contrast is important for the quality of the displayed images and the color reproduction. Here, the colleagues have measured how varied the colors that can represent the four tablet displays.

Again, there is a clear winner. And is again: Kindle Fire HDX 7 The specifications for the smaller color space sRGB surpasses Amazon’s small tablet, with greens even significantly. The second place went to Amazon’s Kindle Fire HDX 8 and the Google Nexus 7 with almost identical readings. They both cover the sRGB color space and are even a little better in the green play there. And the iPad mini with its Retina display? This not sRGB. Especially with the red and green tones weakens the Apple Tablet.

The following figure shows the results of color reproduction measurements again graphically.

These diagrams show the measured color spaces of the four tablets.

angle

For the owner of the tablet itself, the viewing angle may be relatively unimportant – he looks but mostly head-on display. But as it looks for spectators?

Again, the Kindle Fire HDX win 7 As the c’t colleagues have measured the contrast is only from one angle over 60 degrees below a critical value of 600:1. Nexus 7, iPad Mini and Kindle Fire HDX 8 provide some inferior results and are about on par.

The following graphics show once again the angle dependencies of the four tablets. The scale on the x-and y-axis indicate the angle in degrees, the color gives information about the decrease in contrast. Pink is good, over red, orange, yellow and green, the brightness ratio increases from eventually.

The greater the pink area in the middle, the better the viewing angle of the respective tablets.

Conclusion

The result is amazingly clear: Amazon depends on the competition from the display test, the Kindle Fire 7 HDX over its rivals has a clearer projection than its larger brother HDX 8 And just for the multimedia applications they are supposed to also be the strengths of the two Kindle Tablets. With the rapidly converted Android including waiving the Google Play Store Amazon limits its users a clear yes.

The all-rounder Google Nexus 7 and iPad Mini with Retina display must admit defeat. But they are all also rather the all-rounder whose users may ignore one or the other weakness in the screen. Or?

a complete comparison test between the four tablets are available in the next c’t 26/13, the. 30.11 from is available.
