Ulefone Armor 6 Review

Display

Ulefone Armor 6 has the largest display among all Ulefone Armor models and is the first to jump over the 6-inch barrier. With a 6.2-inch diagonal size, it has a resolution of 1080 x 2246 pixels. The brightness of the display is specified as 360 cd/m². Ulefone states a 100% NTSC colour space coverage. The screen is protected by a Corning Gorilla Glass 5. Below you will find our measurements of the white and black luminance, static contrast ratio and colour temperature of the display. The measurements are taken in two different ways. The Single Frame ones show the white and black luminance of a screen that shows 50% white and 50% black. The Separate Frames measurements show the white and black luminance of a fully white and fully black screen. This way you can get a more realistic picture of the static contrast, white and black luminance.

A single frame, 50% white / 50% black

Brightness	White luminance	Black luminance	Contrast	Color temperature
100 %	366.754 cd/m2	0.267 cd/m2	1374 : 1	7693 K
0 %	5.58 cd/m2	0.000 cd/m2	-	7486 K

Two separate black and white frames

Brightness	White luminance	Black luminance	Contrast	Color temperature
100 %	447.346 cd/m2	0.142 cd/m2	3150 : 1	7711 K
0 %	7.497 cd/m2	0.000 cd/m2	-	7431 K

As expected, the white luminance measured when on a whole-white screen is higher than the one measured on a single frame that shows 50% white and 50% black. We get a maximum brightness of 447.346 cd/m² from the separate frames and 366.754 cd/m² from the single frame measurement. The latter coincides with the brightness level specified by the manufacturer. Both values are higher than the ones of the Armor 3 for the respective measurements. As long as it concerns the black luminance, things are just the opposite. The black luminance measured on separate frames is much lower than the one measured on a single frame that shows 50% white and 50% black. Hence, the static contrast ratio received from separate frames measurements is extremely high - 3150:1, while the one received from the single frame measurement is more realistic: 1374:1. The temperature of the white point is within one and the same range for both types of measurements - an average of 7500 K. If we have to compare with the Armor 3 display, the colour temperature, brightness and contrast are improved. Even with a naked eye, we could see that the colours are punchier than usual. The CIE diagram confirms that showing that the display covers more than 100% of the sRGB colour space - that's 100% NTSC as specified by the manufacturer. This level is actually almost exactly as covering 100% of the Adobe RGB colour gamut. The display panel has a traditional vertical striped RGB subpixel arrangement.
