Of course there are apps that can measure the screen brightness usually phones come with the highest of upto 400 nits ( Nits are used to describe the brightness of computer displays, such as LCD and CRT monitors and also mobile displays). When you add square meters, you now measure the light intensity spread over a surface. For writing and searching the Web, 200 nits may be enough. ... You use lumens to measure reflected light, when nit is used to measure direct light." The nit is a unit of measurement for brightness. I'm curious how some reviewers get their numbers of screen brightness . "Brightness is measured in candelas per meter squared (cd/m2) or nits. One last thing that McGowan finds interesting about nit guns and the role of measuring and maintaining brightness levels for signs is that organizations that used to be at odds with each other over sign brightness have now come together in agreement. Low peak brightness (189.3 cd/m2) Samsung J6200. What are nits, and why are they important for your next TV?

The term nit is believed to come from the Latin word nitere, to shine.. As a measure of light emitted per unit area, this unit is frequently used to … You can easily measure the brightness of any light source in the visible with a silicon (Si) or indium gallium arsenide (InGaAs) photodiode.Both can be picked up at relatively low cost especially if buying in bulk. The term nit is actually slang for the standard measurement for luminance, the candela per square meter. Because this is a per-square-meter measure, screen size and nits aren’t related. With so many different types of measurements and contributing factors to overall LED sign brightness, the topic can quickly become confusing. A nit is a unit of measurement of luminance, or the intensity of visible light, where one nit is equal to one candela per square meter (CD/M2). They are simply a measure of how many candles of brightness a display is equivalent to. "Typical brightness ratings range from 250 to 350 cd/m2 for monitors that perform general-purpose tasks. ... We use this new test to measure the maximum peak brightness a TV can obtain while displaying some more traditional video content, instead of displaying our peak brightness patterns. … Although Brightness is not the same as actual quantified Luminance (light output), both TV and video projector makers, as well as product reviewers, have a habit of using the term Brightness as a catch-all for more technical terms that describe light output, which include Nits and Lumens. On average, typical televisions range from 500 to 1,000 nits. M. Mrbobb macrumors 601. Nit is a unit of luminance, or brightness, emitted from a luminous surface equal to one candle per square meter, measured perpendicular to the rays of the source. An outdoor display’s brightness is the one thing that truly sets it apart from an indoor display.
