Which panel technology to choose to editing photos and videos? Large gamut or sRGB ? - 4/8
To display beautiful colors, the panels of our displays have long used three major technologies. With the advent of OLED technology they are now four: TN, VA, IPS and therefore OLED. They have all their advantages and disadvantages and that's what we're going to see on this page because depending on whether you're retouching photos, editing videos or both, you'll have your preference. We will also see that the choice of technology can also influence the uniformity of the panel and its delta and therefore its color display accuracy...
High-end displays have all used the same technology for a very long time: IPS panels. Today, this top-of-the-range supremacy is challenged by the famous OLED technology with its deep blacks. What about the end of 2019 and how to choose between the two? Unless you still choose a TN or VA panel?
And we will see that this is not always without consequences on the uniformity of our panels and the quality of their colors...

Panel technology : TN, VA, IPS or OLED?
Today, four display panel technologies (and their variants) are competing for the market: TN, VA (or PA), IPS or OLED. They all have different advantages and disadvantages unless... unless the most recent one - OLED - brings together all the advantages of each of them and agrees on them in the long run?
1 - TN (Twisted Nematic) panel
This technology makes it possible to vary the position of the liquid crystals in each pixel very quickly to make the light pass or not.

This technology therefore allows very high refresh rates and will be of direct interest to players or even videographers who do not want blurred or remanent effects on moving objects in their videos. The other advantage of TN panel is their very low cost; TN panel are not expensive.
But of course, they also have some flaws and not the least for photo retouchers: their angle of vision before the image darkens is not very wide. To look at the image correctly so with its clarity you really have to look at the panel in front of you so if someone looks at the screen next to you, they won't see at all the same thing as you.
