I do not know when to start, wide color gamut panel becomes very common, the partners of the new purchase of monitors, plus a few dozen dollars to properly replace a wide color gamut panel, such as the kind of 9X% sRGB or even XX% NTSC. However, there are partners who feel that the color is bright enough but always not quite right, especially those who need to see pictures to do design. What’s going on here?
Why would this problem pinch? This is because the LCD panel production line is evolving quickly, wide color gamut panels are getting cheaper, but to accurately control more and more colors need higher performance chips, it is not so fast development and price reduction, so some monitors with wide color gamut panels, but the use of insufficient performance of the chip to save costs, there will be a display of color inaccuracy.
For both the need for color rich enough and color accurate partners, how to pick a monitor? The answer is to look at the color difference (also called color accuracy), which is the indicator of writing ΔE or DeltaE. It refers to the difference between the color presented by the monitor and the actual color (input color signal), the smaller the value, the more accurate the displayed color.
The difference between the displayed color (dots) and the real color (squares) obtained from the test
In general, the home monitor ΔE < 5 can ensure that the average person can not see the color difference; and to make a picture to do video, it is best to choose ΔE < 3, can ensure that professionals are also difficult to see the color difference; as for doing professional design, the best money can be on the ΔE < 1 monitor, so that the work seen on the monitor and the actual delivery of the work of the human eye basically can not see the color difference.
To be more professional, since the color difference is an average, if some colors deviate a lot during the test and others are very accurate, some manufacturers will directly use the best indicator instead of the average ΔE value. For example, the following test results, the red part of the ΔE value can be said to be <3, but the blue and other deviations are a bit large, the average ΔE value is actually just <5.
So, it is best to choose a reliable monitor for design, some of which are now available at good prices. As for those who are particularly cheap, and is completely for home use monitor also claims wide color gamut, low ΔE value is questionable, occasionally do the chart is okay. To really do professional design, it is best to look for its color difference test data to see it.
