FREQUENTLY ASKED QUESTIONS
Brightness is a hot topic in the digital display world. Variances in light output greatly affect how content is represented on an LED screen. Interestingly, legibility of a display can be significantly reduced by too little brightness and too much brightness, so it’s important to consider a number of factors when determining the right brightness for your LED display. For example, if your screen is battling direct sunlight, you’ll need a high brightness setting so that the light from your display reaches the eyes of your viewers. However, if you leave the same brightness on your display overnight, the light output from your screen will be so bright that viewers may not be able to decipher any of the display’s content.
Brightness in our industry is typically measured in nits. A nit is a unit of measurement of luminance (the intensity of visible light), and a nit is equal to one candela per square meter. Typical indoor brightness levels range from 200 to 1,200 nits. Outdoor displays generally have a much higher range, peaking at 8,000 nits or more. Unfortunately, brightness is a highly variable product specification and one that many manufacturers (and resellers) may use to mislead their customers or the industry at large. Depending on the quality of the diodes, most LED displays can be driven to a very high brightness performance, but this can come at a significant cost to the technology itself. For example, as components within your display are worked harder and harder to reach high brightness levels, the lifetime of the overall display can be substantially reduced. Additionally, as power consumption is increased, so too are costs for power usage.
It’s important for you to consult with an expert or manufacturer who is upfront and honest about LED brightness capabilities as well as optimal use.
Yes. We know well the value of allowing potential clients to not only see our display products in action but to have an opportunity to compare pixel pitches from various distances. So we built our primary product showroom in our New York City headquarters, located at 1500 Broadway in the heart of Times Square. There you’ll find showcases from our BRILLIANT™ and BOLD™ product lines, ranging from 0.9 mm to 5 mm, all interior. We have a ThruMedia® transparent video display in the office as well. If you’d like to compare products, we’d love to schedule an appointment with you (get in touch with our team).
Additionally, we’ll be unveiling a new showroom in our Los Angeles office in 2020, and we have plans to open more product demo rooms in other offices throughout the U.S.
We’re often asked about power consumption and how it relates to energy savings. Our selection of high-end diodes allows our display systems to drive diodes at a certain luminance for the life of the display at a much lower junction temperature. In terms of how heat is released in our system, the combination of our PCB design, LED package design, and power supply selection leads to better energy savings as compared to many other LED manufacturers.
Further, our LED displays can be configured with an ambient light sensor, which not only helps optimize brightness in various conditions but also reduces energy waste that can occur when a screen is too bright for its environment.
We help to educate our clients about how their content schedule can improve efficiency (e.g., during off hours, some displays can be set to “idle” which can reduce power consumption to a minimal amount).
We are a global company with more than 2000 employees placed all over the world. Our U.S.-based operations cover all of North America, Central America, and South America. Contact us today, and we’ll find the right representative for you or refer you to one of our international offices.
We established our channel program to support a select group of best-in-breed audio-visual integrators. This division allows us and our technology experts to connect with industry specialists, commercial A/V integrators, key consultants, value-added solution providers and other strategic relationships.

LED stands for light-emitting diode and is a semiconductor device that emits light when an electrical current passes through it. There are two basic types of LEDs typically referenced: discrete LEDs and surface-mounted (SMD) LEDs. A discrete LED, also known as through-hole or dual in-line package (DIP), is a single conducting component mounted through a hold-punched printed circuit board (PCB) and soldered in place. An SMD LED is soldered to the PCB via six pins and is typically packaged with at least two other LEDs as a pixel. For more information on LED types and packaging, see our Pixel Packaging eBrief.
Pixel pitch is the distance between the center of a pixel and the center of an adjacent pixel. Typically, pixel pitch is measured in millimeters. For example, if an LED display has a pixel pitch of 8.0 mm, that means the center of each pixel, regardless of how many total pixels there are in the display, is eight millimeters from the center of an adjacent pixel. Pixel pitch determines the density of pixels in an LED screen. The lower the pixel pitch number, the closer the pixels are together, and thus the higher the pixel density. Pixel pitch is a very important factor when choosing the right LED display and may be affected by optimal viewing distance, proximity to other LED displays, and other environmental aspects. For more information, see our Understanding Pixel Pitch eBrief.
SMD stands for surface-mount device and is a method of mounting and packaging diodes to create pixels. SMD components are mounted directly onto the surface of a printed circuit board (PCB).
A NIT is a unit of measurement of luminance, or the intensity of visible light. One NIT is equal to one candela per square meter.
Brightness for LED displays is measured in NITs, which is one candela per square meter. Typical indoor brightness levels range from 300 to 1,200 NITs. Outdoor displays generally go much brighter, sometimes as high as 8,000 nits or more. Brightness is a highly variable specification, and unfortunately, many manufacturers and re-sellers mislead on this topic. Most displays can be driven to a higher brightness performance, but this comes at the expense of the components—including LED lifetime—as well as higher power consumption. Ask your manufacturer to provide the average or recommended brightness.
Color is a 3-dimensional space. SNA Displays products typically have a higher number of available total colors. High-quality direct-view LED has color space significantly larger than that of television broadcast standards. If you have a standard in mind, please contact an SNA Displays representative, and we will help you find a solution.
Well, it depends on the overall display size, pixel pitch, complexity of design and many, many other factors. Direct-view LED displays can cost anywhere from the tens of thousands to several million dollars. If you'd like to narrow that range significantly for your project, contact a representative on our sales team.
Bit depth, sometimes referred to as color depth or color capacity, is a reference to the amount of color levels a display is capable of. To understand this important metric, see Bit Depth And Why It Matters.
The typical life for an LED display is 100,000 hours, or about 10 years give or take. However, there are many variables that affect LED life, including diode manufacturer, environment, and how the display is used over time. For example, the life of a display could be significantly reduced is a user operates a display at full brightness and bright/light content for the majority of the content schedule. The brightness for LED displays should be regulated and scheduled according to ambient light. For example, screens that are blinding at night because they are needlessly set at full brightness are losing their LED life over time.
We have more than two million square feet of manufacturing space in Shanghai, where the vast majority of our products are fabricated. All work derived in North America, Central America, and South America – from project award to commissioning to post-installation service – is managed by our talented team at SNA Displays.
The length of an installation will depend on the scope of the project and can vary from a few weeks to several months.
The best way to begin the discussion is to submit a query through our website at https://snadisplays.com/about/contact/. Based on the details you provide, we'll assess your project and connect you with the appropriate SNA Displays representative.
Depending on the project scope, various scheduling factors, and project requirements, we typically produce and deliver display products anywhere between 8 and 14 weeks.
