If you've purchased a TV in the past ten years, you know that quality is going up, and prices are going down. As the technology improves, displays are getting larger and brighter and are coming with higher contrast ratios.
We have gone from 36" CRTs to 70" LCDs in our homes. Today's displays are astonishing compared to what was available in years past. These trends created standards and demands that caused a shift in the commercial space.
Think of it like this.
If you're used to a bright 70" display in your living room, an old 55" display is going to look out of place in a 15-person conference room.
Display size makes a huge difference
The first round of displays in conference spaces went up to 70". The latest round tops out around 98". These displays look great and have become affordable for this type of application.
But what if you want something larger? Or something that's a custom size or shape?
That's where Direct View LED walls come in.
What are direct view LED displays?
A direct view LED is a display of light-emitting diodes (LEDs) mounted on a panel. Each LED is a tiny bulb that emits colored light.
Direct view LED video walls consist of several displays working together to seamlessly display content like a single screen.
The video walls have several components:
- The digital displays
- Mounting hardware
- Controller
- Video Source
Direct view LED Video walls have several distinct differences from traditional displays and tiled array video walls (2x2, 3x2, etc.).
Technology
Direct view LED display technology is a cutting-edge solution that offers stunning visual experiences in various settings. It utilizes an array of microscopic light-emitting diodes to create a vibrant and seamless display.
The LED display provides exceptional brightness, contrast, and color accuracy, delivering vivid and lifelike imagery. This technology excels in large-scale applications, such as stadiums, arenas, concert halls, and outdoor advertising, as it can achieve high resolutions with impressive pixel pitch and is visible from long viewing distances.
With its flexibility and scalability, direct view LED technology enables the creation of immersive displays of virtually any size and shape. Its energy-efficient design, durability, and low maintenance requirements make it a cost-effective long-term solution for captivating visual installations.
Sizing
Video walls are purchased and configured by linking smaller panels of LEDs together. Since the panels have no bezels, they can be tiled together for a seamless look at custom sizes or aspect ratios. They have different pixel pitches to choose from, so they can scale to any size. If bigger is your goal, direct view LED is a great option.
Brightness
LEDs are BRIGHT! The average flat panel display in your home or conference room will be 300 to 700 nits in brightness. Direct view LED products can range from to nits. The bright and crisp displays make them ideal for high ambient light environments, like building entrances and feature spaces.

Life Expectancy
The life LED is much longer than your average display. Average consumer displays can range from 10,000-20,000 hours. Commercial displays can stretch out to about 50,000 hours. Many direct view LEDs have an 80,000-hour life expectancy.
The lifetime of these displays is critical as the walls are typically custom sized. This makes replacing a single panel difficult, so you want a product that will last for years.
Energy Efficient
Depending on the content and brightness settings, direct view LEDs can be up to 75% more energy-efficient than LCD panels. This is good for the planet and your wallet.

Questions to Ask
What does LED quality depend on?
LED display pixel pitch refers to the distance between the center of two adjacent pixels on an LED screen. It is measured in millimeters and determines the density of pixels on the display with an integrated matrix device for an even better video signal. Depending on the type, it may have a surface mount diode (SMD pixels) and SMD technology. Using a printed circuit board makes LED viable for many functions, not just as a video wall.
A smaller pixel pitch and fine pitch LED indicates a higher pixel density, resulting in a sharper and more detailed image with greater visible light, which makes it ideal for digital signage. With more detail and fine pitch, the video appears on one seamless display with no visible seams.
The diodes in an LED display are the individual light-emitting components that make up each pixel. These diodes emit light when an electric current passes through them. In an LED display, each diode represents a single pixel and can be controlled independently to create different colors and brightness. The arrangement of these diodes forms the display's pixel matrix, with each diode contributing to the overall image displayed on the screen.
The quality and performance of an LED display depend on factors such as the size and consistency of the diodes used. Higher-quality diodes generally offer better color reproduction and longevity. The arrangement of diodes and their integration within the display structure is crucial in achieving optimal image and uniformity across the entire screen.
What&#;s the distance to the closest viewer?
Direct view LEDs have a specification known as pixel pitch. The larger the pitch, the farther apart the LEDs in the panels are. The smaller the pitch, the closer they are. This will determine how close a viewer can be and see a seamless image without the space between the LEDs. Pixel pitch has a considerable effect on the price of the wall, so you need to know this before shopping around.
What size do you want the display to be?
Direct view LED displays are a good option if you want something 110" or larger. If you need to do a feature wall with an unconventional shape, size, or aspect ratio, then direct view LED displays can accommodate those demands.
Are LED screens a good investment?
LED technology provides an extended lifespan, reducing maintenance and replacement expenses. Their solid-state nature enhances reliability and minimizes the risk of downtime and repair costs. LED walls offer customization and scalability options for things like dvled displays, eliminating the need for significant structural modifications and providing cost savings in installation and future upgrades.
The display's high visual impact with a clearer image attracts attention and potential revenue. An LED video wall provides long-term cost savings through energy efficiency and superior optical performance, making them a wise investment for businesses and organizations. This is why they have skyrocketed in popularity in the past few years.
LCD Video Wall versus LED Solutions - which is better?
When comparing LCD (Liquid Crystal Display) and LED (Light-Emitting Diode) technologies, it is crucial to understand their differences and consider their specific applications.
LCDs use a backlighting system and liquid crystal cells to produce images. On the other hand, LED displays utilize an array of light-emitting diodes as individual pixels to generate light and color, creating an impressive fine pixel pitch for optimal viewing.
In terms of image quality, an LED wall generally offers higher contrast ratios, deeper blacks, and better color accuracy due to its pixel control to provide more immersive experiences. They also offer wider viewing angles and better performance in high ambient light conditions with lovely full-color pixel and brightness levels.
LEDs are more energy-efficient and eco-friendly, consuming less power compared to LCDs. However, LCDs are typically more affordable and readily available in various sizes.
Ultimately LEDs win in almost every respect besides cost. But you may break even in the long run due to their longer lifespan.
What&#;s a baseline budget for your project?
As the technology improves and demand increases, direct view LEDs continue to decrease in price, and the total cost becomes more affordable. However, they still aren't the "cheap" option. Right now, they can be used in smaller spaces like conference rooms. Still, price vs. value can make the traditional flat panel displays a more cost-effective display option. This is why the application is so important to consider.

You may still remember the first TV that came into your home, probably fitted with a cathode ray tube. At the time, the idea of flat screens was almost a science fiction thing, and probably none of the people in the house thought that the appliance had an expiry date. Today, however, we know from experience that this is not the case, and that any gadget is designed to last, at most, as long as the technology on which it is based. So that you don&#;t have to replace your monitor prematurely, we would like to offer these tips to increase your LED display&#;s lifespan.
These recommendations are especially useful for professionals and organizations that decide to include outdoor advertising in their business strategy, either by using giant LED screens, digital sign boards, LED Smart City panels or other similar products. By following some small guidelines, not only will the initial investment be more profitable, but this also helps to improve the technical quality of the campaign and, ultimately, the company&#;s corporate image.
However, before getting into the subject, it is important to point out that we are dealing with a technology that is too recent to talk about complete life cycles. Even so, it is estimated that the average lifespan of an LED display is between 60,000 and 100,000 hours, depending on the use of the screen. Thus, in the best-case scenario, this would be equivalent to using an LED screen for six hours a day for 45 years.
Another aspect that must be made clear is that, when referring to lifespan, we always think of the main component of the screen: the panel, despite the fact that there are other elements that can negatively affect the operation of an LED display. Without going any further, it is much more likely that a circuit will be damaged before the panel is (ignoring, of course, the logical loss of brightness due to the passage of time and the appearance of dead pixels).
Likewise, the replacement of an LED display does not have to occur because it no longer works: its performance may no longer be optimal, which can compromise the achievement of the goals set in any given marketing campaign.
That said, here are our tips to increase an LED display&#;s lifespan.
Avoid places that are too wet or too sunny
We know that the ideal location for an outdoor LED display, at least from an advertisement point of view, will not always coincide with the place that has the best climatic and atmospheric conditions for the conservation of your display. In any case, and although our outdoor LED displays are equipped with rain protection, a rather dry climate with a moderate number of hours of sunshine is more conducive to the conservation of any LED display than one that is rainier and sunnier. As for indoor LED displays, avoid placing them in rooms with humidity or where they tend to accumulate dust. In this way, you can better protect it from environmental conditions.
Make sure that sunlight does not hit the LED display directly
If you are installing indoor LED displays in your store window, make sure that the sunlight does not hit the display directly, as this would force you to adjust the contrast and brightness to very high levels. While Visual LED displays always ensure perfect visibility regardless of environmental brightness, forcing these settings would increase power consumption and therefore could shorten the life of the monitor. Keep this in mind when dealing with window display dressing in your business.
Always place your screen on a flat surface
This recommendation is another of the most important tips to extend the life of your screen. If the screen is not going to be hung on the wall, it should be placed on a surface that is resistant and not tilted. To select the ideal distance for users, multiply the size of the TV by four and place it at the user&#;s eye level, as it can make them lose interest if they have to force their neck to view the screen properly. Otherwise, it could cause discomfort.
Use a surge suppressor and a voltage regulator
Although there are many users who mistake them, the truth is that these are two different elements. Surge suppressors are devices designed to counteract short voltage surges, equivalent to a network cycle. These elements can be accompanied by other protections, such as filters against electromagnetic interference and electrical noise. When the duration of the surge is prolonged, or frequently repeated, the suppressor may be damaged and stop working, so this is not a suitable solution for regulating the voltage.
Voltage regulators, in turn, counteract voltage variations with a duration of more than one network cycle, i.e. over 16.6 milliseconds. In this way, a voltage with great stability and without fluctuations is achieved, even if there are increases and decreases in the voltage on the grid. Thus, in short, the voltage regulator provides a constant level of voltage, essential for the proper functioning of any electrical device.
Therefore, both the surge suppressor and the voltage regulator are complementary and equally necessary, so it is not recommended to use both of them. Currently, there are companies that sell them both integrated in a single regulator technology (or electronic regulator).
Do not use abrasive liquids to clean the screen
To extend your LED display&#;s lifespan, it is essential to always use products with a suitable formulation for the external components of the display. In saying this, we are not just referring to chemical products, but also to other products commonly used at home to polish televisions, such as vinegar. When you buy your screen, Visual Led will tell you which products are best suited to remove dirt from your LED display.
We also recommend using a special cloth or soft chamois, such as that used to clean glasses, slightly moistened with water.
Do not touch the screen with your fingers
It may seem obvious, but this is one of the most common mistakes made by both individuals and companies. In case you need to change the location of your LED displays for shops and shop windows, always hold them at the ends. Obviously, you also have to be careful not to accidentally bang them.
