Here are the charts from the CalMan 4 software comparing the measurements of the HTC One's screen to those of the Samsung Galaxy S4.

This slideshow shows the charts from the CalMan 4 software that were used to form the basis of the findings in the article "HTC One vs. Samsung Galaxy S4." It contains all of the raw numbers and data gathered from each phone, for anyone who's curious.

The titles of the slides indicate the phone and the settings tested. For the GS4, settings include Screen mode (Movie, Dynamic, etc.) and Auto Adjust Screen Tone, abbreviated AAST.

Here's a brief key to the chart, clockwise from the upper left.

-- Where the ISF logo is, there's an area for filling in picture setting details; it goes unused for these charts since phones lack those settings.

-- The large RGB balance bar graph and the "x, y, Y_" table immediately below shows how black ("0") through gray and finally full white ("100") test patterns measured. Ideally all three of the red, green, and blue bars should be close to "100" on the graph's vertical axis. "Y_" is light output in nits, and "dE2000" is the color error.

-- The second table below the bar graph, with the first row listing "white, red, green...100W" shows how the color test patterns measured.

-- The "Gamut CIE" diagram is a visual representation of those color numbers, showing how close the measured display came to the target color. Ideally the colored circles should be as close as possible to the squares of the triangle, which represent the sRGB/Rec 709 standard gamut. The same goes for the central white circle, whose target square is the D65 standard white point. Again, "dE2000" is the color error.
