Display

The Ulefone Armor 15 has a 5.45-inch IPS screen with an HD+ resolution (720 x 1440 pixels). It is from an older generation with non-curved corners and thick bezels. The display settings are standard for an Android 12 smartphone. They allow you to switch between the light and dark themes, turn on/off automatic brightness, adaptive brightness, and night light. You can choose from several wallpapers, charging animation, font sizes, and display sizes. The screen color mode provides a choice between standard, vivid, or cool colors but these are not pre-calibrated color modes. Home screen, notification LED, and lock screen settings are also part of the display options.

Our measurements show a maximum brightness of 441.281 nits. Below you will find our usual measurements of the white and black luminance, static contrast ratio, and color temperature of the display taken twice - on a single frame that displays 50% white and 50% black and on two separate frames displaying a fully white and a fully black screen.

A single frame, 50% white / 50% black

Brightness White luminance Black luminance Contrast Color temperature
100 % 441.281 cd/m2 0.389 cd/m2 1134 : 1 9840 K
0 % 17.42321.397 cd/m2 0.015 cd/m2 1162 : 1 10130 K

Two separate black and white frames

Brightness White luminance Black luminance Contrast Color temperature
100 % 440.539 cd/m2 0.399 cd/m2 1104 : 1 9833 K
0 % 17.21 cd/m2 0.016 cd/m2 1076:1 10281 K
The white and black luminance levels of the display measured in both ways almost do not differ. The maximum brightness on a 100% white screen from the single frame measurement is 441.281 cd/m2 and from the two separate frames measurement it is 440.539 cd/m2. The black luminance from the two measurements is also almost equal hence, there isn't a significant difference in the contrast ratio measured in both ways and it is an average of 1000:1-1100:1. The temperature of the white point is within the 9800-10000 K level.
Display brightness uniformity
Position Left Center Right
Top 398.448 cd/m2 / 9294 K 400.299 cd/m2 / 9338 K 397.078 cd/m2 / 9363 K
Center 417.777 cd/m2 / 9700 K 428.664 cd/m2 / 9786 K 421.939 cd/m2 / 9726 K
Bottom 432.217 cd/m2 / 9844 K 439.40 cd/m2 / 9778 K 440.825 cd/m2 / 9578 K
Our brightness uniformity measurement shows that the display is not uniformly bright but without any staggering differences. The top one-third is the least bright with an average of 399 cd/m2. The mid-one-third is the mid-brightest part of the screen with an average of 422 cd/m2. The bottom one-third is the brightest one with an average of 436 cd/m2. The left vertical part of the screen is the least bright. The central vertical and right parts are relatively equally bright. The temperature of the white point is an average of 9800 K.
The CIE diagram shows that the display sRGB color space coverage is close to 100% but is not exact. The green and red ranges of hues will look slightly duller, while the yellow and orange hues will be slightly more saturated. The display panel has a traditional vertical striped RGB subpixel arrangement.
