Nits vs Lumens vs Luminance
No matter what display screen it is, when we first see it, the most directly eye-catching thing is the displayed content. But even if the display content is the same, the display effect may vary due to different brightness. Some are dim, some are bright, and of course, the required brightness varies depending on the application location. At this point, we often encounter words that represent brightness, such as Nits, Lumens vs Luminance .
So when we make a decision on which display screen to use, we need to understand the meanings of these words?
About Nits
Do you know what Nits are? In fact, Nits (or Nits) are both measures of brightness. The word nit comes from the Latin word nitere, which means “luminous”. However, it does not belong to the International Unit of Units or any measurement system.
1 nit = 1 candela per square meter.
In simpler terms, nit is just a different name for candela.
If it is an ordinary application scenario, indoor equipment, 500nits is basically sufficient, but if it needs to be used outdoors, 500nits is far from enough. It is best to use 800nits for outdoor display. Due to outdoor equipment, you need to consider whether the image can be clearly seen, and if normal display is required under sunlight, higher brightness will be needed
About Lumens
Regarding lumen (lm), it is a unit of measurement for luminous flux in the International System of Units (SI). Luminous flux is usually measured in lumens to measure the brightness emitted by a light source. And it is often used in light bulbs to describe the brightness of light. Other than light bulbs, projectors also use lumens as a unit of measurement .
About Luminance
Luminance (Lv) refers to the measurement of the amount of light emitted, reflected, or passed through an object. Its unit is (cd/m ²), Measure the amount of light in candela per square meter.
Although there are various units of measurement such as nits (nt) and foot lamberts (fl), only candela per square meter (cd/m ²) is designated as the International System of Units (SI) for Luminance
FAQ
What is the unit of measurement for luminance ?
Candela per square meter (cd/m ²).
What is the difference between luminous flux and luminous intensity?
Luminous flux refers to the total amount of light emitted by a light source throughout its entire angular spectrum. But luminous intensity refers to measuring the light emitted by a light source in a given direction.
Is there any difference between brightness and luminance ?
Brightness does not have a quantitative measure. But luminance has .
How to choose a suitable lcd display for the project ?
If your project application for the outdoor device ,you must choose a high brightness LCD display , over 800nits brightness . But if you only need use this LCD display indoor , you don’t need such high brightness . Normal brightness just enough , Such as 200~500nits .
Summary
Understanding the lumens, nits, and luminance meaning . That is an important factor when choosing LCD display for your project. But in addition to brightness, other parameters need to be considered when choosing a display screen, such as size, pixels, contrast, and refresh rate. These are all factors that need to be taken into account when selecting a display screen. If you have any question or need any support , please contract us in anytime .
