We"ve got a 5.5-inch AMOLED panel with a 1080 x 1920 resolution. The imagery is sharp and, thanks lớn a very elaborate screen color customization menu, we can get either very punchy colors, or a very subdued, easy-on-the-eyes look.In short, if not entirely color-accurate, the display is a pleasure to lớn look at & covers a variety of tastes. Unfortunately, it doesn"t get very bright, so viewing out in the sunlight is not always a great experience.

The CIE 1931 xy màu sắc gamut chart represents the mix (area) of colors that a display can reproduce, with the sRGB colorspace (the highlighted triangle) serving as reference. The chart also provides a visual representation of a display"s color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on đứng top of its respective square. The "x: CIE31" và "y: CIE31" values in the table below the chart indicate the position of each measurement on the chart. "Y" shows the luminance (in nits) of each measured color, while "Target Y" is the desired luminance level for that color. Finally, "ΔE 2000" is the Delta E value of the measured color. Delta E values of below 2 are ideal.These measurements are made using Portrait Displays" CalMAN calibration software.

The màu sắc accuracy chart gives an idea of how close a display"s measured colors are to lớn their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to lớn the target ones, the better.These measurements are made using Portrait Displays" CalMAN calibration software.


The Grayscale accuracy chart shows whether a display has a correct white balance (balance between red, green and blue) across different levels of grey (from dark khổng lồ bright). The closer the Actual colors are khổng lồ the Target ones, the better.These measurements are made using Portrait Displays" CalMAN calibration software.
