When a TV or video projector is touted as able to output 1,000 Nits or Lumens, that does not mean that the TV or projector outputs that much light all the time. Questions to ask your customer: SUNLIGHT LEGIBILITY OF MOBILE PHONE SCREENS ... E6 also has 1000 nits brightness(i read it in gsmarena's review) and there is no 710, no lumia 900 and no Galaxy SIII. 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. This is especially important for HDR-enabled. The screen area is determined by multiplying screen width and height stated in square meters.Using the 500 nit 65-inch TV which as 1.167 square meter screen area, the lumens equivalent would be 1,833. Of course, many other factors contribute to whether a display is sunlight readable (reflective or transflective polarizers, Blanview technology, etc. If you have a scene with the Sun in the sky, that portion of the image may require the TV or video projector to output the maximum number of Nits or Lumens. © 2021 Emerald X, LLC. Although the term Lumens has been a mainstay of video projector marketing for some years, when shopping for a TV, consumers are now being hit with the term Nits by TV makers and persuasive salespersons. Things like total cost of maintenance, how the VMA manages bandwidth, what cameras are supported, what level of cybersecurity is provided, and what integrations are available to use are important factors IT managers have to think about when assessing a video […], ha ha I remember one panoramic display at the the street that blinds the drivers hahaha. Luminance indicates the amount of light emitted by a light source at a given solid angle per a given unit of area. Brightness may also be expressed as a percentage more bright or a percentage less bright from a subjective reference point (such as the Brightness control of a TV or video projector—see further explanation below). While ruggedized laptops (which are made for service workers such … Our eyes have a tremendous dynamic range because everyday we experience a tremendous range of ambient lighting levels from absolute darkness (0 lux) up through direct sunlight (120,000 lux). Here the amount of light is measured as the power emitted by the light source. Just as with any specification or tech term that is thrown at you by a manufacturer or salesperson, don't obsess. Although a 600 Nit OLED TV and 1,000 Nit LED/LCD TV can both look impressive, the 1,000 Nit LED/LCD TV will still produce a much more dramatic result, especially in a well-lit room. A large format LED display needs to output at least 6,500 Nits to be seen in full sunlight. This is due to projectors having difficulty in displaying high brightness in a very small area in relation to a surrounding dark image. Rugged laptops can generate as much as 1,500 nits, as can modern 4K HDR TVs. Working in IT has enough challenges without adding in the complications of surveillance video. If you’re going to place a screen by a pool, in the middle of a plaza, or facing west, it must be at least 700 nits to appear bright and readable in direct sunlight. If you are shopping for a video projector, as mentioned above, a light output 1,000 ANSI Lumens should be the minimum to consider, but most projectors are capable of outputting 1,500 to 2,000 ANSI lumens, which provides better performance in a room that may not be able to be made completely dark. Brightness is not the same as actual quantified Luminance (light output). Luminance and illuminance are two words that sound very similar in English. Measuring light output with reference to the relationship between Nits and Lumens deals with a lot of math and physics, and boiling it down into a brief explanation isn't easy. For 720p/1080p or Non-HDR 4K Ultra HD TVs, information on Nits is not usually promoted but varies from 200 to 300 Nits, which is bright enough for traditional source content and most room lighting conditions (although 3D will be noticeably dimmer). In outdoor environments under the shade, such a display can provide an excellent image quality. Some cheaper laptop screens are only 200 - 250 nits, and are only suitable for use indoors away from a window. All these variations require different levels of light output. This information applies to TVs from a variety of manufacturers including, but not limited to, those made by LG, Samsung, Panasonic, Sony, and Vizio and video projectors from manufacturers such as Epson, Optoma, BenQ, Sony, and JVC. However, when considering light output, here are some guidelines to keep in mind. As a general rule, anything above 400 to 500 nits will do pretty well on a sunny day, but at 200 nits, you might have to find some shade to … Tell Us About Your IoT/Collaboration Meeting Room Plans for 2021 & You Could Win a 60" Display! The goal of HDR is to support increased light output capability so that displayed images have characteristics that are more like the natural light conditions we experience in the "real world.". Be sure to read the detailed analysis for the lux levels and Tablets below. In outdoor environments under the shade, such a display can provide an excellent image quality. “The dramatic difference is between 400 and 700 nits.”. They may never need more than 300 or 400 nits. Positive mode monochrome and multi-color transflective TFTs. However, remember, the standard applies to the maximum Nits output, not average Nits output. 1000 ANSI Lumens is the minimum that a projector should be able to output for home theater use, but most home theater projectors average from 1,500 to 2,500 ANSI lumens of light output. HDR (High Dynamic Range) is all the rage amongst TV makers, and there is a good reason for consumers to take notice. As mentioned previously, 2,000 Nits is currently the highest light output level that may be found on a TV, but that may result in displayed images that are too intense for some viewers. He is also a systems administrator for an IT firm in Texas serving small businesses. In outdoor environments under the shade, such a display can provide an excellent image quality. Brightness can be referred to as the ability to detect differences in Luminance. Also, different colors that are displayed contribute to different light output levels within a frame or scene. For instance, a fast-food chain might use a screen for its drive-thru while a mining or … Nits and Lumens are only one part of the equation when considering the purchase of a TV or video projector. Get your latest project featured on TechDecisions Project of the Week. Technically, a device starts counting as “sunlight-readable” when it hits at least 1,000 nits, but very few mobile displays go that high. However, I have not yet found a specification that defines sunlight readable. Outdoor flat panel displays go up to 5,000 nits. Outdoors that same device would be barely readable. Thank you. Thank you Chrissy. Luminance is the amount of light reflected from a surface, which is different from the total light in the room, or the light that goes towards the surface (illuminance), or the total light per a given angle (luminous intensity). There’s a not a huge demonstrable difference between 700 nits and 2,000 nits. 2,000 nits is not three times brighter than 700 nits,” says Tom Dixon, vice president of marketing at SunBrite TV. If you want to do the reverse, divide the number of Lumens by 3.426. For TVs and Video Projectors, Nits and ANSI Lumens are both measures of light output (Luminance). Brightness is below 400 nits here, and there is no sunlight brightness mode that gives this a boost above 500 nits, which is something Samsung provides on their AMOLED-laden Galaxy S7 series. What You Need to Know. “It’s a bit of an arms race with specs. There’s a not a huge demonstrable difference between 700 nits and 2,000 nits. They give the display intensity ranging from ~ 700 nits to 2100 nits. You concisely explained everything one would reasonably need to know to start in a quick and easy to read way. Lowering the "brightness" results in making dark portions of the image darker, resulting in decreased detail and "muddy" look in darker areas of the image. Getting more precise, other factors, such as TV screen size also affects the Nits/Lumens relationship. Reaching 1,000 nits for enhanced readability can be accomplished using a hybrid approach with only minimal increases in … ), but at around 500 nits, the backlight can overpower the sunlight to make the display readable. Measuring only 5.5-mm thick and weighing 390 g, the AngleView family of TFT LCDs feature a luminance of 150 nits while consuming only 4.1W of power.
