LED stands for light emitting diode, and they are flat screens that use tiny lights called diodes to show images, videos, and text.
They are extremely common. Even the screen you’re reading this text on is an LED screen.
These screens typically include lights, circuit boards, power supplies, and protective casings. Businesses use LED screens for everything from digital signage to billboards and video walls. Stadiums even use them for scoreboards.
But there’s more to LED displays than just bright colors and sharp images. The technology has evolved so much over the past decade that there are now many types of LED screens, and they perform far better than older traditional screens.
In this guide, we’ll cover what LED displays are and how the technology works. We’ll even show you how to pick the right screen for your business.
Let’s get to it.
What Is an LED Display?
An LED display uses light-emitting diodes to display images and videos. Each tiny diode acts as a pixel that lights up on its own.
These LED diodes emit red, green, and blue light and mix them to create every color you see on the screen.
When you combine thousands or millions of these diodes, you get a full picture.
Now that you know what this technology is, it’s time to go through the components that make up an LED screen.
What Are The Components of an LED Screen?
The components of an LED display include a power supply, modules, panels, cabinets, and pixels. Each part has its own job, and when they all work together, you get those high-quality visuals we all love so much.
Here are more details about each component and how they work:
- Power supply: A power supply converts electrical current to the right voltage for the diodes. If the voltage isn’t stable, screens can flicker or wear out faster.
- LED modules: This is a small, self-contained unit that holds one or more diodes. They fit together like puzzle pieces to build the full screen.
- Panels: When you join multiple modules to create a larger board, that’s what we know as panels. You can arrange them in different ways to fit the screen size you want. It’s pretty flexible, so you can design something that suits your space or business use case.
- Cabinet: The cabinet is like the body that holds everything together. It protects the electronics from rain, dust, and bumps. Outdoor cabinets use strong, weatherproof materials, while indoor ones stay light and easy to move.
- Pixels and pixel pitch: As you already know, each LED pixel uses red, green, and blue light to create color, and the space between them is called the pixel pitch. A smaller pitch gives you a sharper and clearer picture, but screens with higher pixel density show finer details and smoother images, especially at close range.
Did you know? According to the United States Department of Energy, LEDs use up to 75% less energy than older technology. So you get lower power consumption and better performance for a fraction of the cost.
How Does LED Display Technology Work?
Light emitting diode displays use a process called electroluminescence. When an electric current flows through a diode, the diode emits light.
Think of each diode as a little semiconductor device with two layers. One layer has extra electrons, and the other has spaces where electrons can fit. The moment electricity starts flowing through them, electrons move from one layer to the other.
And when electrons jump across the gap, they release light.
Still with us?
The material inside each diode decides the color it gives off. Some materials glow red, while others glow green or blue. When all of them glow together, they create images you see on the screen.
Now, you might be thinking, “Does the screen just choose colors at random?” Not exactly.
There’s a small controller inside the screen that acts like the brain of the display. It tells those little diodes when to turn on, how bright to shine, and when to rest. And it happens thousands of times every second, which is pretty amazing when you think about it.
One last thing…
Every display has a refresh rate, which shows how many times per second the screen updates. Most LED displays have a refresh rate between 60 Hz and 120 Hz, but some high-end screens can even go up to 700 Hz (that’s pretty rare, though).
Higher refresh rates are important because they help reduce motion blur during fast scenes or quick camera movements.
So next time you watch a video or play a game, just remember what’s working behind the scenes (quite literally!).
What Are The Different Types of LED Technologies?
There are many types of LED monitors, including edge LED, full-color RGB, OLED, AMOLED, mini-LED, micro-lED, and quantum dot LED displays.
Let’s take a closer look at how they work and where you’ll see them.
Edge LED
Edge LED displays work in a simple but clever way by using LED backlighting along the edges of the display. A diffusion panel then spreads the light evenly across the screen, which keeps it bright while reducing thickness and weight.
Many modern TVs and monitors use this setup because it maintains a balance of performance, design, and cost.
Here are some benefits of Edge LED screens:
- They’re thin and lightweight, so they fit easily on walls or compact desks.
- Edge LEDs are more affordable than other LED or LCD displays, which makes them ideal if you’re looking for something within a reasonable budget.
- The diffusion panel provides a bright and clear image, which is usually enough for everyday use.
- They work well in homes and offices where you need to ensure both style and practicality.
You should also consider these drawbacks of Edge LED displays:
- Brightness may appear uneven, especially around the corners of the screen.
- Contrast and black levels in Edge LEDs are not as deep as those on full-array LED or OLED displays.
- Not ideal for high-end gaming or movie buffs who want perfect color depth and accuracy.
Edge LED screens give you a nice mix of good looks and a fair price. They may not hit the same level of picture quality as high-end models, but they still get the job done for everyday use.
In our experience, if you want something slim, bright, and easy on the wallet, Edge LED is a solid pick.
Full-Color (RGB) Displays
Full-color RGB LED displays use tiny red, green, and blue lights in every pixel. When these colors mix, they create the colors you see on the screen. This setup makes them popular for large outdoor advertising and indoor video walls because the images look wonderful.
Here are some good reasons to choose a full-color LED display:
- The colors look rich and accurate, so photos and videos look excellent.
- Full-color LEDs’ wide color range works well for ads, events, or any display that needs detail.
- The screens seem bright and clear even under strong indoor lights or sunlight.
- Colors maintain consistency across the whole screen without any dull spots.
However, there are a few downsides to keep in mind:
- Full-color LEDs cost more than basic single-color screens.
- They use more power since all three color lights work together.
- You’ll need to maintain it frequently to keep colors balanced and sharp.
Overall, full-color LED displays make your content look lively by keeping images sharp and clear. Their balance of brightness and color improves the overall image quality.
Do you want your pictures or videos to look colorful and professional? Simply go for full-color LED displays. You won’t regret it a bit.
OLED
OLED stands for Organic Light-Emitting Diode. In an OLED display, each individual pixel can produce light on its own, which gives the screen remarkable control over brightness and color. That control helps the screen create the desired image with incredible accuracy.
Businesses love OLED displays for their superior contrast ratios, accurate colors, thin profiles, and wide viewing angles that deliver stunning picture quality. However, the higher upfront costs, potential color degradation over time, and risk of screen burn-in make them less practical for companies on a budget or applications that require constant static imagery.
AMOLED
AMOLED is a step up from regular OLED screens. It adds a control system called an active matrix, which tells each pixel when to light up. This produces a faster, sharper, and more efficient screen.
You’ll usually find AMOLEDs in smartphones. The display you’re reading this on? It’s probably an AMOLED screen.
Let’s go through some positives and negatives of AMOLEDs.
Pros of AMOLED displays:
- Fast response time for smoother motion and quick touch feedback.
- They use less power by updating only the pixels that need to change.
- AMOLED displays show bright, vivid colors with excellent clarity.
- These screens work well with dark themes and save more battery in the process.
Cons of AMOLED displays:
- Higher production cost compared to traditional LED displays and a standard LCD (Liquid Crystal Display) screen.
- Shorter lifespan due to organic materials wearing out over time.
- Screen burn-in can happen if one image stays too long on display.
So, if you want to experience rich colors and smooth visuals, AMOLEDs are the right choice. A small warning: just be ready to spend a bit more for that extra sparkle. You’ll love it.
Mini-LED
If you’re someone who doesn’t want to spend OLED-level money but still wants amazing picture quality, we recommend mini-LEDs. These screens use thousands of tiny lights behind the display.
Each light is smaller than a grain of sand (less than 0.2 mm across), which gives the screen more control over brightness and contrast.
Mini-LED displays give you excellent contrast, impressive brightness, and longer lifespan than OLED without the burn-in worries, all at a lower price point that still delivers premium visuals. The trade-offs are occasional blooming around bright objects on dark screens, narrower viewing angles than OLED, and a higher price tag than standard LED displays.
Fun fact: Some of the latest mini-LED TVs pack over 20,000 tiny lights behind the screen. That’s like having a sky full of stars working together to light up your favorite shows.
Micro-LED
Micro-LED takes things a step further by using lights that are even smaller than mini-LED. Every pixel is less than 50 micrometers wide (about the size of a living human cell!). And it gives off its own light, so the screen does not need a backlight.
This technology mixes the best parts of OLED and LED. You get deep blacks like OLED, along with the strong brightness and long life of LEDs.
Here are some advantages of Micro-LED displays:
- Excellent contrast with true blacks and bright highlights.
- Micro-LED technology reaches higher contrast ratios than older LED designs.
- Long lifespan that can reach around 100,000 hours.
- High brightness levels that stay clear even in bright rooms.
- Great energy efficiency compared to older screen types.
But the downsides include:
- Very expensive due to the complex production.
- Limited availability, mostly found in luxury or commercial products.
- Smaller screens are harder to make, so most models are really large.
Unless you’re planning to go all in for the best picture quality out there, Micro-LED might be more screen than you really need right now. It’s amazing to look at, but your wallet might need a moment to recover.
What Are The Different Types of LED Displays?
LED displays come in many types, like small, medium, and large screens, as well as video walls, indoor LEDs, and outdoor LEDs. The right one for you depends on where you plan to use it and how close people will be when they watch.
To make things easier, let’s walk through the main types so you can figure out which one you need.
Small
Small LED displays are less than 10 square meters, which makes them a good choice for smaller spaces. If you’re looking for something that shows menus, product details, or directions clearly, these screens work well in shops, restaurants, or office areas.
Since people stand close to these screens, small LED displays usually need a tighter pixel pitch between 1.5mm and 3mm to keep the image clear. They’re also easier to set up and maintain, and they use less power than bigger models.
Many businesses start with a small display to see how customers respond before investing in a larger one. It is a simple and cost-effective way to learn what works best.
Medium
Medium LED displays range from 10 to 20 square meters. Conference rooms, retail windows, and mid-sized venues commonly use this size.
The pixel pitch can range from 2mm to 4mm depending on viewing distance. So, you get enough screen space to show detailed content without breaking your budget.
We also recommend them for hybrid events where both in-person and remote viewers need to see the same information.
Large LED Displays
Large LED displays can reach 100 square meters or more. Stadiums, concert venues, and major intersections use these massive screens.
Most large outdoor displays use 6mm to 10mm pitch. You sacrifice some close-up clarity, but the image looks crisp from far away (because not everything needs a zoom-in).
These large displays are also built to handle weather, temperature swings, and constant use. Based on our experience, these screens need professional installation and regular maintenance to perform well over time.
LED Video Walls
LED video walls are modular displays built from multiple panels. You can customize the shape and size to fit any space.
Video walls are popular in control rooms, corporate lobbies, and broadcast studios. They let you connect multiple screens to build one borderless LED video wall. You can also show just one large image across the entire display.
Indoor LED
Indoor LED displays are designed for controlled environments. They prioritize high screen resolution to produce visually stunning images.
These screens typically use a smaller pixel pitch, between 1.2mm and 4mm. The tighter spacing gives you sharp images at close viewing distances. Indoor displays work great for shopping malls, airports, and corporate offices.
Outdoor LEDs
Outdoor LED displays are built to resist rain, dust, and extreme temperatures.
And since you’ll be competing with direct sunlight, these outdoor models typically come with much brighter screens than indoor models (typically 5,000 nits or more).
Pixel pitch ranges from 4mm to 10mm since outdoor viewing distances are greater, and you don’t need ultra-sharp images.
One more thing…
Outdoor displays use sealed cabinets with IP65 or IP66 ratings. The protection keeps moisture and debris out of the electronics. You’ll find these screens on highways, building facades, and outdoor events where weather protection is non-negotiable.
How to Choose the Ideal Screen for Your Business?
You choose the ideal screen by assessing your space, setting a budget, and matching the display type to your specific use case. The process becomes straightforward once you know what factors matter most for your situation.
We’ll walk you through the decision process from start to finish. These steps will help you match the right display system to your specific needs and budget.
Step 1: Decide If You Want to Rent or Buy
Renting makes sense for short-term events like conferences, trade shows, or seasonal campaigns. You’ll save money on upfront costs, and you won’t have to pay to maintain it. When you’re done, just give it back!
Typically, our customers who are organizing events rent displays for 3-7 days at a time.
Here’s a good rule of thumb: if you plan to use your LED for more than 30 days, buying is a better option. If it’s for a few weeks or less, rent.
Step 2: Measure Your Space
Next, we need to measure the space where your display will go. Grab yourself a measuring tape and get the height and width in meters or feet.
After you get the size of the space, you need to measure the viewing distance. Stand where most people will watch the screen and measure back to the wall. This will determine what pixel pitch you need for clear images.
Here’s a tip that most people forget: Check for obstructions like columns, doors, or windows that might block part of the screen. If there are any, clear them out immediately!
Write down all your measurements before you talk to suppliers. Exact dimensions save time and prevent you from ordering the wrong size. You should also take photos of the space to share with installers.
Step 3: Set Your Budget
LED displays can cost anywhere from about $1,000 to tens of thousands of dollars, so make sure you have your budget in mind. If your budget is a bit tight, go with a higher pixel pitch or cheaper model.
Large outdoor displays can cost anywhere from $50,000 to $200,000 or more (you’ll want insurance on that thing, trust us).
It’s impossible for us to say how much your screen will cost, because there are so many factors at play. Please contact our team if you’d like guidance on setting a budget. We are available to talk 24/7!
Note: Your budget should include installation, mounting hardware, and control systems. Some suppliers bundle these costs, while others charge separately.
Step 4: Choose the Right Display System for Your Use Case
Here are our recommendations for the right LED display for common use cases:
- Retail Stores: 2mm–3mm pixel pitch, SMD LEDs for sharp close-up viewing
- Outdoor Billboards: 6mm–10mm pitch, DIP LEDs for weather resistance and brightness
- Corporate Lobbies: 3mm–4mm pitch, SMD technology for professional medium-distance presentations
- Sports Venues: 5mm–8mm pitch with high refresh rates for stadium viewing
- Conference Rooms: 2mm–3mm pitch for detailed presentations viewed from 3–6 meters away
- Transportation Hubs: 4mm–6mm pitch with high brightness for busy airports and train stations
- Control Rooms: 1.2mm–2mm fine pitch for monitoring detailed data from close range
- Shopping Malls: 3mm–5mm pitch for atriums and common areas with varied viewing distances
