What is brightness on a TV or other screen?



The competition between TV and image makers has been warming up quickly, and everyone is talking about how many "nits" their screens have. But what is it for a rivet? And why should you bother?

Nits is a brightness unit

No, we are not talking about head lice here, but rather a part of the terminology used in the technology world. Long story short, a rivet is a unit of measure that describes how light a TV, smartphone, computer screen, laptop computer screen or other type of screen is. The higher the number of nits, the brighter the display.

Sounds simple, right? But do not describe "lumens" brightness? And why are nits so important to you as a consumer? Let us answer some of these questions.

What exactly is a "Nit" Anyway?

Interestingly, nit (which comes from the Latin word rite, which means "to shine") is not an official unit of measure since it is not technically part of the international system for units or any other measuring system. The official term is actually "candela per square meter." But we assume that "nit" is easier to remember.

So let's break it down. Since you now know that "nit" is just a hose for "candela per square meter", you also know that a nit measures two things: Light intensity (candela) and area (square meter).

If you may have guessed, "candela" is Latin for "light". So a candela is equal to the brightness of a single average light. Two chandeliers are equal to the brightness of two lights, and so on.

When adding in square meters, you now measure the brightness spread across a surface. So a candela per square meter (or a rivet) is the brightness of a light that shines on a surface measuring one meter above and one meter down.

Put it in simpler terms, imagine that you are holding a piece of poster board that measures one meter by one meter – which is about the size of a regular billboard. Then light a candle and hold it up in front of your billboard. The amount of light that hits your billboard from the candle is equal to a rivet (or a candela per square meter).

If the brightness measurement in the light seems a little weird, remember that we still use the word "horsepower

What is the difference between nits and lumens?

You may think that we already have a unit of measurement for measuring light intensity lumen. After all, it is what we use to measure the light intensity of light bulbs, flashlights, projectors And much more, however, nits and lumen measure different things.

A big difference is that the lumen does not indicate light over a specific area that nits do. Lumens rather indicate the light intensity coming from the source, however large or small. projectors are all measured in the lumens.

Another way of expressing this is that the lumen indicates the amount of light a projector itself emits, while the nits measure the amount of light emanating from the projector's screen. [19659005] Why should you care about nits?

So now that you know all the technical mumbo jumbo about nits, you might ask yourself the most important question: Why should you even bother? [19659004] RELATED: Are you going to get an "Ultra HD" 4K TV?

The core is that the higher the number of networks a TV has, the brighter the screen is. This may not be a big factor for you when shopping for a new TV, but for the worth, the brighter a TV can get, the better the picture will look in a bright room.

Nits are even more important when it comes to smartphones, which you are more likely to use outdoors in the strong sunlight. A screen with many nits will look bright and clear even on the most sunny days.

However, I would argue that when it comes to TV shopping, you don't have to pay much attention to how many nits a TV has, and most will not even be able to tell the difference.
