In this article, I am going to explain to you in detail about the screen contrast ratio. You might have read that this XYZ display has a 1000:1 contrast ratio. But what does that mean? Should it be lower?, or Should it be higher?

Everything related to this contrast ratio will be explained in this article. My approach here will be to stay on the layman's side as much as possible. Because we all know that Wikipedia has information about the topic I'm going to explain. But, due to a lot of technical terms, it's hard to understand.

So, let's get started.


What's the screen contrast?

Screen contrast means the different colors that the display can produce and visible easily and directly by the naked eyes, outdoor, and indoors. Without thinking much, see the below image.

In the above, there are two columns, and each of them has 4 colors.

In the left column of the image, the 4 different colors are easily visible, and, as I said, they are different from each other. And the same for the right column.

Now, compare the first color bar of both the left and right column. You can clearly see the difference between them. The first color bar of the right column is lighter in contrast to the first color bar of the left column.

Now, try to look at this image in a room with direct sunlight.. Are you guys able to see it clearly? If yes, then the screen has a good contrast ratio. If no, then there's something lacks.

So, now how to define the contrast ratio?

The screen contrast ratio is defined as the ratio of the brightest light emitted by the screen to the darkest spot created.

Difference between the Good and Bad Contrast Ratio-Display

There's a clear difference between the display of good and bad contrast ratio. See the below image. The display on the left side shown in the below image has a good contrast ratio compared to the right. In the same image, there is a picture of a bridge with some buildings. See how it looks dirty in the bad contrast ratio-display when compared to the good contrast ratio one.

What should be the Screen Contrast Ratio?

The contrast ratio always differs within the types of the device. And, the higher the ratio, the better the darker spot it can create.

In laptops and monitors, it depends on the type of panel and, it's very limited. But, the ideal results are as follows.

  • For IPS panel: 1000:1
  • For VA panel: 3000:1
  • For TN panel: 1000:1

If we consider mobile devices here, then this number will explode. Nowadays, these devices are coming with an almost 1000000:1 screen contrast ratio, which makes it far better accurate in dark spot creation.

How we measure it?

Measurement of the screen contrast ratio involves the special-dark laboratory. It also involves the custom environment to set up.

At Thanalysis, we don't measure it. The data of the screen contrast ratio that we provide in our review articles are from the manufacturer's website.
