Hey, are you looking for Some great Tips on Content Creation For Outdoor and Indoor LED Displays screens? Learn how to get best results for your next advertising campaign. Here are best practices for Digital Signage Content creation.

Each LED Display screen is different. Prior to creating content, make sure to test it with our template to check the readability and render of images, colours and texts. It will allow you to make sure that you content always looks as intended.

In Content Creation For LED Displays it is important to respect the exact pixel size of the screen. We recommend to avoid software automatic scaling of images and videos. It is best to create content with the exact pixel resolution of the electronic sign, it will offer best quality and viewing experience for target audience. Tests have proven that increasing the image size will not specially improve quality – to the contrary. To help you calculate the Resolution, check out

Make sure you don’t use any bright colors like white or red for full screen background. This can cause many issues. First, if used often, it will reduce the lifespan of the LED digital sign. Furthermore, it will certainly use more electricity. Finally, it will be too bright for your target audience to look at. And that is the main goal, get people to look at your electronic sign. Potentially, it can cause more severe issues, like distracting drivers, and cause accidents. To solve this, we recommend to always use darker and softer colours for your backgrounds.

To get bets readability effect, we recommend the use common fonts like Arial, Helvetica, Verdana, … This is what is generally called “Sans Serif”. In other words, Your text must be BIG and Crisp. Avoid any use of drop shadow, bevel, glow or other text effects. and don’t forget to use the recommended contrasting colours for maximum readability.

One thing that often happens is the mixing of text and images or videos. This is because the medium allows for many creative possibilities. But always make sure you separate text from images. They must never overlap. Mixing them will certainly make your message unreadable for your target audience. To solve this, create a separate slide for text or divide your canvas in zones. Alternatively, you can try to find creative ways to get your text to stand out. By having your text clearly visible, your composition will look more professional and will be readable for your audience.

Outdoor and indoor led sign boards are great marketing tool. They allow for videos, images, animation,… This is why when creating content for digital displays designers will often add a lot of animations to their composition. Of course it looks great on the preview, but unfortunatelyit will often distract your target audience from the key message. They might be watching the display when the animation is only taking place and cannot actually see what is the message. This is why we recommend to avoid text animations especially.

Our final advice to improve your content over time is: go and see the results on location. It is the best and only way to check the quality and impact of your campaign. it will help you address any issues that you may notice on site. If you are a professional, make sure you have at least one person dedicated to creating your content or checking it, because experience is key.

Did you know that, according to a recent study by Global, 85% of brands and agencies plan to increase their advertising investment? This figure illustrates the importance of this aspect in any marketing strategy. And although the Internet is usually the star medium, indoor and outdoor advertising is also gaining ground in shopping malls and big cities. Are you thinking of boosting your sales with this option? If so, and although we have already explained how LED technology works, it is important to also know what the advantages of LED are over LCD displays, two technologies that, at first sight, can be quite similar.

Before explaining the advantages of LED over LCD displays, we should highlight that the demand for this type of product for shop windows is booming for several reasons. One of them is that LED screens fulfil their function much better than their predecessors, LCD screens, because of the excellent image quality they provide and their ability to attract the attention of passers-by on the public highway.

But what is the difference between the two technologies? First of all, the technology of any LED TV is similar to that of the LCD screen, since, technically, they are also an LCD (these are the acronyms of the concept ‘liquid crystal screen’). However, there is a fundamental difference between the two: the generation of light. In the case of LCDs, the light is provided by neon tubes, whereas it is LED bulbs (light-emitting diodes) perform this function in LED displays.

On the other hand, the number of diodes on LEDs are than the number of neon tubes on LCD screens, which means that the lighting is higher quality. In addition, this makes LED displays thinner. The color contrast is also higher, providing a sharper and higher quality image.

Another advantage of LED displays over LCDs is that they will save electricity for your company. For example, the power consumption of the LED display can reduce the power consumption by up to 50% in comparison to similar LCD TV with the same operating hours and.

Another benefit of LED has to do with the conservation of the planet. The reason is that LED, being a mercury-free technology – unlike other monitors – is more environmentally friendly and sustainable. It is also better for people’s health, as exposure to mercury, even in very small quantities, can cause serious problems and harm fetuses when it comes to pregnant women. Mercury is equally toxic to the digestive system, the nervous and immune systems, the skin, the eyes, the lungs, and the kidneys.

Want more advantages of LED over LCD? Here’s another one that will help improve your business numbers: while the life of an LCD is usually no more than 60,000 hours, until its light source burns out, LED displays can run for between 60,000 and 100,000 hours. However, it’s not just about quantity, but also quality: while LED TVs are equipped with technology that always provides an optimal color palette, even when the color starts to fade, the LCD starts to show more and more black dots in the picture, due to continuous use (and corresponding to neon tubes that have stopped working).

And since we are talking about image quality, we should also refer to the behavior of the liquid crystal displays – both LEDs and LCDs – when they are directly affected by sunlight. For example, when we are in front of LED screens in shop windows or giant LED displays that emit during daylight hours (video scoreboards in stadiums would be a case in point). In this context, only LED technology can guarantee optimal viewing conditions at any time of day.

In relation to outdoor displays, we should also bear in mind that they require special protection, both against rain and vandalism. When this happens, only professional LED displays can offer this advantage.

Now that you are clear about the advantages of LED displays over LCD, you are probably considering purchasing an LED monitor for your business. This is where we get to the million-dollar question: how much does an LED display cost? The question is not simple, since the final bill will depend on several factors, such as its equipment or its dimensions. In Visual Led, in addition, we design LED screens to fit your needs and investment capacity.

Do you want to know how much an LED display would cost you? If so, we encourage you to calculate the price of an LED display online. You only have to introduce the requested variables, and you will instantly receive an estimated budget without any commitment of purchase on your part.

Of course, we must not lose sight of the fact that the marketing of outdoor LED displays is relatively recent and is part of a marking regulated by the laws of each country. Therefore, in some territories, certain formats must be adapted to the current legislation.

One of these choices is deciding between an LCD display or an LED video wall. Continue reading to find out more about the basics, as well as the advantages and disadvantages of each solution.

Most people are familiar with LCD technology, which stands for Liquid Crystal Display. These types of displays have a massive presence in this world, used in living rooms to watch movies, fast-food restaurants to showcase menus, airports to show flight schedules, and everything in between. LCD technology was developed in the 1960s and has been used worldwide as a standard for roughly 20 years. It is a tried-and-true technology that has stood the test of time and will be around for the foreseeable future.

On an LCD screen, the panel is illuminated by a light source and works through reflection or transmission of light. Overall, LCD displays have better viewing angles and less glare than LED screens. This technology was designed to be energy efficient and tends to be lighter in weight.

An LCD video wall is made up of multiple LCD panel monitors mounted on a surface to create a digital canvas, which then work together to create a unified experience. They operate 24/7 at a high brightness and have thin bezels that help create a seamless look when the displays are placed next to one another.

Bezel thickness and the brightness rating are among key attributes to consider for an LCD video wall display. Here is what each of these means and why.

Bezel:Bezel thicknesses for video wall displays are measured in “bezel-to-bezel” thickness.This is the thickness of the bezel when two displays are placed next to one another. Displays can be either large bezel or thin bezel.

Nits:Brightness is measured in Nits. A higher Nit value means the display will be brighter. A brighter display is necessary in a room that sees plenty of direct sunlight, or if the intent is to draw in visitors from far away. With LCD video walls, the price of the hardware goes up as the display size and brightness increase, and the bezel width decreases.

The next item to consider is the type of content that will be displayed on your video wall. LCD displays have high resolution screens — modern 4K displays have over 8 million pixels! This means that the content being displayed is highly detailed and crystal-clear. A viewer could stand less than 1 foot away from the screen and be able to see exactly what is being shown on the screen.

Like previously mentioned with LCD video walls, an important consideration in the decision-making process is the type of content that will be displayed on the video wall. LED video walls suffer from image degradation and pixilation from up close, so fine details will be lost, and text will be illegible. If detail from up close is important, LCD displays are much better suited for that situation.Content examples that are well-suited for an LCD video wall:

Video walls are relatively new. But LCD technology has had decades of mainstream adoption, and with that comes both familiarity and lower costs. If those are important to you, then an LCD video wall is likely the right choice.

LED video walls are similar to LCD video walls, but the digital canvas is built using LED panels. Individual LED panels can be anywhere from 12”x12” to 36”x18”, which is much smaller than LCD displays. LED panels have a larger presence in this world than most might think—they are found indoors and outdoors at stadiums, arenas, concert venues, airports, and in use as large digital advertisements in iconic places such as Times Square.

The module is a small rectangular board that contains all the individual LEDs (light-emitting diodes).Unlike LCD, there is no glass or color filter on the LED video wall panels. The individual diodes that are placed on the modules produce both color and light.

One of the most impressive features of LED panels is that they can be combined to create almost any shape, without a bezel interrupting the digital canvas. LED video wall panels can be placed on curved surfaces, 90-degree edges, and other non-standard surfaces. The smaller size of the panels in relation to LCD video wall displays means they can fill more space on a surface—they aren’t limited to standard 46” and 55” sizes as are LCD video wall displays.

The most important factor to consider when scoping LED panels for a video wall is what is referred to as “pixel pitch.” The pixel pitch is effectively the distance between each pixel on the LED panel—a pixel pitch of 6mm means each pixel is spaced 6 millimeters away from the adjacent pixel. The smaller the pixel pitch, the smaller the distance is between each pixel, which means there are more pixels per square inch on the digital canvas.

Pixel pitch factors into viewing distance. When the pixels are close together, the image is more detailed and can be viewed comfortably by others from a close distance. But when the pixels are spaced further apart, a viewer needs to stand further away to view the image clearly.

Lastly, pixel pitch impacts the price of the LED video wall more than any other factor. For example, a 2mm pixel pitch LED video wall costs significantly more than its 10mm pixel pitch counterpart.

As is the case with an LCD video wall, an LED video wall will add exciting drama and premium value to showcase spaces. LED panel displays don’t enjoy the benefit of decades of mainstream adoption as do their LCD counterparts. However, the technology curve is increasing their availability and lowering their costs. At this time, an LED video wall will have higher upfront costs compared to an LCD video wall. If cost is the main concern, then an LED video wall system will not likely fit into your budget

An LED video wall would be well-suited and cost-justified if the intent of the video wall is to provide an immersive viewing experience from a further distance. This could be content with lots of movement, animation, imagery, and bright colors to draw viewers into your space or provide a unique experience.

Aside from LED video wall cost, there are other factors to consider which could make an LED video wall system the frontrunner for your project. Here are the advantages and disadvantages to consider:

Limitless shapes and sizes:the smaller size of LED panels allows them to be combined to create unique canvases, including curved, 90-degree edge, and other combinations not possible with LCD displays

Easy maintenance and service; high reliability:LED module replacement takes seconds with little effort; LED panels are rated with a lifetime of 80,000-100,000 hours, depending on the product

The LED light display screen has indoor and outdoor application. Beside the waterproof IP grade, the brightness required for Indoor and Outdoor application are different.

So for the LED components used, according to the brightness level are divided into for regular brightness (800-1000 nits) indoor LEDs and high brightness (4000 - 6000 nits) outdoor LEDs.

The smallest indoor LED 0808 allow to make the smallest pixel pitch P1.0 Indoor LED display screen， while there are P1.25, P1.56, P1.667, P1.875, P1.923, P2, P2.5, P3, P4, P5, P6.

Indoor LED Display Modules made with regular brightness LED,there are P1.0, P1.25, P1.56, P1.667, P1.875, P1.923, P2, P2.5, P3, P4, P5, P6 LED Display Screen Modules.

You need to consider and well-known for the sizes of the LED display screen modules, to calculate the QTY. of LED display screen modules need for LED display screen / wall in different sizes.

2) Iron Sheet Standard Cabinet: Simple made, and can custom-make to any sizes. Note: customized size need to match with the LED display screen modules. Features: Light Weight, Independent disassembly box, High Brightness, High Grey Scale, Cabinet Size and Shape can be Customized Freely.

Each model of the controller/card has its max loading pixel pitch quantity (LED quantity).  We learn before that the different pixel pitch LED display modules vary a lot.

LED video wall vs LCD video wall comparison takeaways will be relevant for several forms of display technology and will help you make the right choice when exploring video wall options. Getting your message across to dozens if not hundreds of people daily is an important endeavor, and you want to make sure the display helps you connect with your audience, team, or community more easily.

Over the past few years, video walls have become ever more ubiquitous; today, you won’t only find them in public places but also in workplaces, schools, art galleries, exhibition centers, research institutions, social and sports events, and even houses of worship. Of course, you want the images to be bright, sharp, and immersive. The beauty isn’t only outside, though, as it’s the underlying technology that impacts the video wall’s quality.

In the past, the most common display technology for video walls was LCD, but today’s large-format all-in-oneLED displays have many advantages that have helped them become the new industry standard very quickly. In this post, we’ll discuss the differences between LED and LCD large format displays in more detail, give a general overview of each technology, and delve into the reasons why a high-quality all-in-one LED displayis invariably the best option for large-format display requirements.

Historically, LCD video wall display technology has been the most popular and it’s a good place to start with technical insights. LCD stands forliquid crystal display. Liquid crystals are sandwiched between the polarizing filters and electrodes and topped withthe display surface (something we casually refer to as a screen). The bottom part of the video wall is made of fluorescent lighting which backlights the liquid crystals. The light passes through the crystals and those – powered by varying electric current – produce the desired color.

LCD video wall displays are usually constructed by linking together four or more LCD screens. That’s because individual panels are not big enough and have size limits. The downside is, the bigger number of panels will be assembled, the heavier the display will become. That makes delivery and installation more difficult.

A major benefit of LCD displays is the sharp, crystal-clear image quality, which is especially apparent when you come up close to the display. Besides, its long-standing status as the most popular technology for video walls has helped to ensure the product’s relatively low price.

LCD technology remains a perfectly viable display option, but, aside from challenging delivery and setup, it is no longer regarded as the go-to video wall solution. Keep reading to find out more reasons.

Although LED technology for video walls is nothing new, it’s quickly gaining in popularity thanks to all its improvements. It has, consequently, become more accessible.

While LCD is a multi-layered thick device, the LED is much thinner and more effective. In contrast to LCD technology, LED video walls are typically constructed from modules of light-emitting diodes (LEDs) making the whole display slimmer and with higher brightness capability (discussed later in the post). Each diode works as the actual display pixel — emitting Red, Green or Blue (RGB) values to create any desired color. Since the LEDs produce the image for the display themselves, they don’t need any backlighting or filtering which considerably reduces the number of layers.

Within the broader category of LED video walls, there are also different packaging technologies. For more context, those include surface mount diode (SMD), integrated matrix device, and dots in place, but the real breakthrough happens elsewhere. It’s the chip-on-board orCOB technology, that has emerged as the LED game-changer of recent times. The most revolutionary aspect of this invention was the tightest pixel pitch that allows the direct mounting of the diodes onto the print circuit, placing them evenly along its surface.

The emergence of all-in-one LED displayshas also helped to improve the technology’s popularity. A Direct View LED display eliminates the LCD panel, resulting in a brighter picture and greater color clarity. Most importantly, it eliminates the grid issue and image uniformity when combining multiple LCDpanelstogether, so there are no lines breaking up the displayed content. This is whyDirect ViewLED technology can now create much larger video walls. The very latest all-in-onesolutions also integrate power, display,image stitching,and control systems for the ultimate user experience.

At the heart of the LED display vs LCD display comparison, it’s all about the use, impact, and price. In the sections below, let’s explore some of the various elements that make up the user’s experience and the cost-effectiveness of a video wall. That includes some of the plus points and drawbacks of these two competing technologies.

Let’s tackle the overall viewing experience. This is an area whereDirect ViewLED technology excels. Rather than serving as a backlight, the LED display adopts red, green, and blue LEDs for each pixel, and adjusts the values of each of those colors to create billions of possible colors for use on the display itself. Coloring the image directly from the light emitted from the diodes helps to provide a truer depiction of color, which can work magic in terms of heightening the audience’s sensory receptiveness.

Calibrating and synchronizing all the LCD screens require specific software that will add, both in costs and complexity, to the overall system. Each LCD panel operates, and therefore degrades, on an individual basis, which means they require calibration at different times. Panel degradation definitely adds up to the total cost of ownership.

Finally, it should be noted that added thickness of LCD displays — imagine over 110 mm — can also look cumbersome or unwieldy in an indoor space. This can detract attention away from the content being shown on the screen. By contrast, a high-end,All-in-One LED displaywill have a thickness of 25 mm – 35 mm with a 5 mm frameless edge. This is substantially less thick than LCD video walls and positively influences ideal viewing distance and immersion.

Even if LCD video walls are made of high-end screens, still their lack of brightness invariably results in poor visibility as soon as they’re viewed from a distance or under strong ambient light. This means that there are clear limitations when it comes to using an LCD video wall to display content.

Prior to the emergence of Direct View LED video walls, these limitations may have been more acceptable to the average user, but that has started to change. The high-end LED displays provide higher brightness while also making it possible to adjust brightness levels on the device itself. This often may be essential for optimizing the specific settings of the video wall (as low brightness images won’t be clear even if you can adjust the display for the strong ambient light).

Resolution-wise, most LCD displays come with 1080p but 4K UHD is available, which is the same as LED’s. However, the Direct View LED’s fine pixel pitch means that the LEDs are ultra-close to each other, so even when you’re closer to the display than usual, you’d still be able to clearly see the visuals. This can have an extra impact when showing vivid landscapes, detailed product images, design sketches or mechanical drawings in spaces of various sizes.The real-to-life color depiction is made possible thanks to the light being directly seen by human eyes without going through different materials which is the case for LCD. LED also delivers a wider color gamut, and the very best options on the market offer 120% coverage of the Rec.709 color space.

ViewSonic All-in-One LED video walls address the challenges of the past with finesse thanks to the Direct View technology and, for the most advanced models, Chip on Board (COB) packaging. For example, the multi-award-winningAll-in-One LED Displayprovides up to 4,440Hz ultra-fast refresh rates and 600-nit adjustable high brightness, offering an unparalleled viewing experience in any space.

Another important thing to remember when comparing LED display vs LCD display is the difference in shipping, installation, and all-around maintenance of a video wall. This is one of the areas where all-in-one LED video walls really outperform LCD video walls in almost every way imaginable, resulting in a far better experience for end users and greatly reducing the amount of time and effort needed to set the video wall up.

LCD large-format displays will have significantly higher shipping and installation costs. This is partly because an LCD video wall installation will require at least three people, often taking more than 4 hours. Furthermore, on top of free-standing models, LCD video walls can only be installed on a wall.

By contrast, an All-in-One LED Display can be installed in around two hours, thanks to the all-in-one modular design. Individual modules will automatically configure and calibrate to their location relative to the rest during installation.

One of the challenges associated with LCD video walls is the fact that each panel operates independently, so there is a realistic chance that one panel will wear out before the others. The core issue here is that if one panel wears out, the cost of tearing down the display to replace it and then deliver it will be high.Besides, the repair process takes around a month and during this time the LCD cannot be in use. After fixing, the display will need to be calibrated again. In the long term, this translates to high maintenance costs.

This is not true for LED video walls, thanks to the modular approach. In such cases, you would need to replace the single LED module without removing the whole screen. Besides, the LED modules can be swapped out while the display is powered on and in continuous use. This means anyone can replace a defective piece for quick and easy maintenance. The industry term for it would be “full front maintenance with no downtime”.

Each LCD display has different color and brightness, so calibration is needed upon installation. And each display will change over time (the degree of degradation of brightness and color performance also varies by each display), so users will take further time and effort to calibrate for maintenance.

LCD video walls have traditionally required an additional control box and a variety of other accessories and components to provide a smooth display and an acceptable user experience. Until relatively recently, this has also been true for LED displays and resulted in an unsatisfactory user experience, more complex maintenance, and day-to-day management. Often, a specialist technician would be needed to even get a large format display up and running.

Fortunately, the emergence ofAll-in-One Direct View LED displays has helped to change all of this. Such a comprehensive solution will combine everything the user needs in a single package. Imagine a control system, display system, and power supply that are all integrated together along with the image stitching technology. Crucially, such an approach results in a far superior and more user-friendly experience, with no need for specialist knowledge.

As the cherry on top, the all-in-one LED display can be turned on with just one click and is easy to operate with remote control. Additionally — aside from wireless content sharing — the display’s I/O port provides easy connection options.

These latest displays are compatible with AV control systems, includingCrestron, Extron, and AMX, providing excellent control and automation options without complicated setup. These devices also offer many connectivity options for maximum levels of convenience.

While LCD video walls have historically been the most popular option, improvements to LED technology and thus its greater affordability ensured a clear frontrunner of any Direct View LED wall vs LCD video wall debate. A high-quality, Direct View LED video wall will be easier to install, manage, and operate on a day-to-day basis. There are affordability benefits as well, and modern all-in-one solutions deliver excellent user-friendliness from the get-go.

A Direct View LED video wall, otherwise called LED display, will also offer a superior overall viewing experience, with improved brightness, color gamut, contrast, and all-around flexibility. Users will not need to worry about grid issues or irregular aspect ratios, and for these reasons, LED’s cutting-edge technology is widely regarded as the ultimate solution for large displays.

The excellent visual effect, strong multiple functions and high cost-efficiency allow LED display screen to influence more enterprises and industries further and deeper.

By advertising various contents, commercial values of the locations can be expanded. For instance, commercial advertising LED display can display videos, images, text, lantern slides and other media format, while can change the contents frequently and immediately if there is need.

LED commercial advertising display screen can display your advertisements and information 24/7 hours, and the long service life make sure your investment worthwhile and profitable. But for outdoor printed advertisement billboard, you need to change it frequently.

You can also use it togenerate more revenues from sponsorship or other payed ways. It is worth to be highlighted that LED display may be one of the most suitable and ideal tool for you to achieve these as other displaying technologies will have more limitations such as weaker protection ability and lower brightness. We will go into details about this point next.

We have referred some advantages of commercial LED displays in the previous contents, but do you know why should we choose it as the one but not other displaying technologies such as LCD display or projectors?

LED or LCD, which one do I really need? This is a common question that will be asked by some customers. As you may know, one of the most obvious differences lays behind whether there is a backlight.

Just as the name suggests, LCD (Liquid Crystal Display) display contains a liquid crystal which will change state when current is applied to it. If you want it to light up, there should be a light behind it because it emits no light of its own. The light is what we call “backlight”. While for LED (Light-emitting- diode) display, it can emit light by itself.

The brightness of LED display is higher than LCD display. Even under direct sunlight, it can display the images and videos clearly, while LCD display is more susceptible to ambient light.

LED display has a wider viewing angle which can up to 160°to ensure people can see the images clearly from different angles. However, for LCD display, viewing angle is more limited and narrower.

The contrast ratio is much higher than LCD display, and the high contrast will increase the visibility under different conditions. For example, no matter in indoor or outdoor with strong daytime sunlight, commercial LED screen can show picture details greatly.

The ratio is about 10:1 when comes to power consumption of LCD and LED screen. The lower power consumption can save money for users and prolong service life.

For instance, LED cabinets can be installed as LED video wall (refer to display with huge size), and theoretically, the size can be unlimited. This feature allows LED screens seamless, no bezels appearance, whereas LCD display screens inevitably have bezels on the surface, and can not achieve large display.

The working life of commercial LED signage is much longer than that of LCD. Basically, the lifespan of an commercial LED advertising display can reach 50,000 hours while that of LCD screen can only reach 30,000 hours. That means, if you use them 10 hours a day, the working life will be 15 years and 8 years respectively.

Indoor LED screens usually havesmaller pixel pitchthan outdoor ones as the closer viewing distance. The common pixel pitch includes P1.25, P1.86, P2.5, P2.604, P3.91 and so on.

Moreover, the protection ability will be lower than that of outdoor LED display such as IP43. And the brightness is not as high as outdoor screen as the ambient light is weaker than daylight.

There are different types of ICs used in LED displays, and Drive IC accounts for about 90%, so here we mainly discuss the impact of Drive IC on prices.

Different raw materials have different features like different weight and heat-dissipation ability. Therefore, you can not just choose LED cabinets depending on price.

For instance, when you want to choose a celling LED display, then aluminum LED cabinet can be your wise choice for its light weight and high heat-dissipation.

You may know LED lamp beads decide large part of the price. Generally, we have three brands: Nationstar, Kinglight and San’an.The inital price of Nationstar LED lamp beads will be typically higher than that of San’sn and Kinglight.

Stage LED display, also known as stage rental LED display or background LED screen, can create different vibe for stages, and can achieve seamless splicing and gigantic size.

With a set of virtual production LED wall, people can interact with the creatures and nature there when filming in the workplace, and see the changes of light and shadow during the sunrise and sunset of the entire day by advanced move-capturing technology, and indoor full color LED display.

Commercial LED displays can be installed on the top or facades of buildings, major highways, bus stations or other places where have huge human traffic so that the screen can support advertising campaign to get profits.

Unlike advertising objective, commercial LED displays sometimes will be used as tools to promote brand image in amusement park, showroom, exhibition and so on. They can show corporate videos, products or programs or presentations to promote services and brand images.

Through high-quality displaying and immediate management and control, commercial LED screens can achieve real-time data feedback as information display window. As a result, we can often see them at stock exchange, hotel, train station, airport and other places where need immediate information communication.

Not like other displays like LCD screen or projector with fixed sizes and shapes, advertising LED screen can be designed as different shapes and sizes due to the modular feature.

As to modular design of LED displays and dual-service feature of many LED display modules, it requires for less maintenance even can be completed within severial seconds.

Moreover, the quick installation is also simple and straightforward. For some small-size LED screen, the installation can be achieved very quickly just with one person.

Sometimes we will prefer to smaller pixel pitch, as it determines the clarity and resolution of your LED screen modules and the minimum viewing distances. However, you need to consider it based on the actual using scenarios.

For example, if you are going to install the displays near a highroad, then small pixel pitch LED display may not be a cost-effective choice as the smaller the pixel pitch, the more expansive the screen.

For outdoor LED display, brightness should be high enough to avoid unclarity under comparative strong ambient light. At the same time, it should not be too bright to cause damages to eyes and dizziness. Generally, the brightness level will be between 4500-5000 nits.

Display performance determines the final effect of the whole LED display screen. You can judge it from several aspects including grayscale, pixel density, refresh rate, brightness uniformity, viewing angle, driving chip, LED lamp beads, and so on.

LED screens are not consumer electronic, so the technical support of LED screen suppliers is vital. It is worth noting that even some companies claim they have offices outside their own countries, these offices are sales offices but not technical support offices that staffed by technical experts.

Before purchasing LED display screens, power consumption is another considerable factor, too. Buyers can calculate electricity consumption from power consumption of each pixel, and the total amount of pixel.

Now, you may have already realized there should be a investigation before making the decisions. We can consider it from many aspects such as display performances (just ask the sellers for detailed specification and on-site pictures), power consumption, customer support, viewing distance and so on.

There are two ways of control methods, one is synchronous control method, and the other is asynchronous control method. There are two concepts that a LED display user and owner must know.

This control method is used to display real-time content without any latency.You can display almost any contents on the screen through management of the controlling computer, and the computer should turned on, and work properly, otherwise the LED display can not work normally, too.

Of course, if you need both of the two control methods, you can choose dual-mode LED players which support both of them. That means, you can switch each of them when needed, all based on your specific requirements.

The basic LED control system includes controlling PC, sending controller, LED screen wall, and sometimes, LED video processor. Here we have a special article for you to understandLED display control system, just click to jump if you are interested in!

Shopping for a new TV is like wading through a never-ending pool of tech jargon, display terminology, and head-spinning acronyms. It was one thing when 4K resolution landed in the homes of consumers, with TV brands touting the new UHD viewing spec as a major marketing grab. But over the last several years, the plot has only continued to thicken when it comes to three- and four-letter acronyms with the introduction of state-of-the-art lighting and screen technology. But between OLEDs, QLEDs, mini-LEDs, and now QD-OLEDs, there’s one battle of words that rests at the core of TV vocabulary: LED versus LCD.

Despite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. Think of it as a shutter, either allowing light to pass through or blocking it out.

Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section.

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different from one another in important ways. Let’s dig into each.

CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Since CCFLs are larger than LED arrays, CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming. TVs using full-array LED backlighting to make up a healthy chunk of the high-end LED TV market, and with good reason — with more precise and even illumination, they can create better picture quality than CCFL LCD TVs were ever able to achieve, with better energy efficiency to boot.

Another form of LCD screen illumination is LED edge lighting. As the name implies, edge-lit TVs have LEDs along the edges of a screen. There are a few different configurations, including LEDs along just the bottom, LEDs on the top and bottom, LEDs left and right, and LEDs along all four edges. These different configurations result in picture quality differences, but the overall brightness capabilities still exceed what CCFL LCD TVs could achieve. While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. Sony’s technology is known as “Slim Backlight Master Drive,” while Samsung has “Infinite Array” employed in its line of QLED TVs. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

Local dimming is a feature of LED LCD TVs wherein the LED light source behind the LCD is dimmed and illuminated to match what the picture demands. LCDs can’t completely prevent light from passing through, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture. This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark.

Local dimming helps LED/LCD TVs more closely match the quality of modern OLED displays, which feature better contrast levels by their nature — something CCFL LCD TVs couldn’t do. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing. Here’s an overview of how effective local dimming is on each type of LCD TV.

TVs with full-array backlighting have the most accurate local dimming and therefore tend to offer the best contrast. Since an array of LEDs spans the entire back of the LCD screen, regions can generally be dimmed with more finesse than on edge-lit TVs, and brightness tends to be uniform across the entire screen. Hisense’s impressive U7G TVs are great examples of relatively affordable models that use multiple-zone, full-array backlighting with local dimming.

“Direct local dimming” is essentially the same thing as full-array dimming, just with fewer LEDs spread further apart in the array. However, it’s worth noting that many manufacturers do not differentiate “direct local dimming” from full-array dimming as two separate forms of local dimming. We still feel it’s important to note the difference, as fewer, further-spaced LEDs will not have the same accuracy and consistency as full-array displays.

Because edge lighting employs LEDs positioned on the edge or edges of the screen to project light across the back of the LCD screen, as opposed to coming from directly behind it, it can result in very subtle blocks or bands of lighter pixels within or around areas that should be dark. The local dimming of edge-lit TVs can sometimes result in some murkiness in dark areas compared with full-array LED TVs. It should also be noted that not all LED edge-lit TVs offer local dimming, which is why it is not uncommon to see glowing strips of light at the edges of a TV and less brightness toward the center of the screen.

Since CCFL backlit TVs do not use LEDs, models with this lighting style do not have dimming abilities. Instead, the LCD panel of CCFL LCDs is constantly and evenly illuminated, making a noticeable difference in picture quality compared to LED LCDs. This is especially noticeable in scenes with high contrast, as the dark portions of the picture may appear too bright or washed out. When watching in a well-lit room, it’s easier to ignore or miss the difference, but in a dark room, it will be, well, glaring.

As if it wasn’t already confusing enough, once you begin exploring the world of modern display technology, new acronyms crop up. The two you’ll most commonly find are OLED and QLED.

An OLED display uses a panel of pixel-sized organic compounds that respond to electricity. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “emissive” displays (meaning they require no backlight). They offer incredibly deep contrast ratios and better per-pixel accuracy than any other display type on the market.

Because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. OLED panels are often found on high-end TVs in place of LED/LCD technology, but that doesn’t mean that LED/LCDs aren’t without their own premium technology.

QLED is a premium tier of LED/LCD TVs from Samsung. Unlike OLED displays, QLED is not a so-called emissive display technology (lights still illuminate QLED pixels from behind). However, QLED TVs feature an updated illumination technology over regular LED LCDs in the form of Quantum Dot material (hence the “Q” in QLED), which raises overall efficiency and brightness. This translates to better, brighter grayscale and color and enhances HDR (High Dynamic Range) abilities.

And now to make things extra confusing, part of Samsung’s 2022 TV lineup is being billed as traditional OLEDs, although a deeper dive will reveal this is actually the company’s first foray into a new panel technology altogether called QD-OLED.

For a further description of QLED and its features, read our list of the best TVs you can buy. The article further compares the qualities of both QLED and OLED TV; however, we also recommend checking outfor a side-by-side look at these two top-notch technologies.

There are more even displays to become familiar with, too, including microLED and Mini-LED, which are lining up to be the latest head-to-head TV technologies. Consider checking out how the two features compare to current tech leaders in

In the world of TV technology, there’s never a dull moment. However, with this detailed research, we hope you feel empowered to make an informed shopping decision and keep your Best Buy salesperson on his or her toes.

LCD displays don’t emit light by themselves. They need a light source, and LED backlights are now dominating the market. In this article, Orient Display’s Bill Cheung provides a complete overview of LED backlight technology, discussing different types, driver technologies, color deviation, brightness options and more.

LCD (liquid crystal display) has long been the dominant technology in the display world. Certainly, there are some emerging competing display technologies—such as OLED (Organic Light Emitting Diode) [1] and micro-LED—that have the potential to threaten LCD’s position in the market. But both are currently only used for niche and high-end markets.

An LCD display can’t emit light by itself. In order to have an LCD display [2] used in a dim environment, a backlight has to be used as the light source. There are a few different technologies that are able to produce backlight ranging from EL (electroluminescent), CCFL (cold cathode fluorescent lamps) and LED (light emitting diode). However, a breakthrough in blue LED technology by Shuji Nakamura [3] led to LED backlights dominating the market.

One of the greatest benefits of LED backlighting is its long lifetime. Normally, LED lifetime can be measured with half-life when the original brightness decreases by 50%. With different LED chip manufacturing materials, technologies and environment used, the LED life can vary from 20,000 hours to well over 100,000 hours.

LED backlights have low power consumption and produce much less heat than other backlight technologies, which extends the durability and performance of the other display components. Furthermore, this reduces the risk of fire and explosion. LED backlights are also driven with DC (direct current) and low voltage (can be as low as 1.5V), which are good for battery drive and emit no interference to the circuitry. With the development of LED technology, the LED chips become small. So, it is possible to produce very thin backlight (0.5mm thick or thinner).

Although white LED is the most popular color, LED backlight can be made into different single colors, bi-colors and tri-colors [4] (Figure 1) (Figure 2). With RGB LED backlight color mixing, normal 8 color LED backlight can be produced (Figure 3).

LED backlight can be classified as bottom (array) lit and side (edge) lit backlights, and each have their plusses and minuses. The advantages of the bottom lit (array) backlight are that it is uniform and bright. Its disadvantage is high current draw, thickness, heat dissipation and cost. Meanwhile, the advantages of the side lit backlight are its thinness, flexibility in design, low current and lower cost. The main disadvantage of the side lit backlight is its non-uniformity—hot spots can be seen from most of the side lit backlight from certain angle. Figure 4 compares the bottom lit and side (edge) lit backlight LCD types.

Now let’s look at LED backlight structures. An LED backlight can be simplified into layers starting with a LED chip, light guide, diffusor and reflector (Figure 5). This is the lowest cost structure. Except for some very low current efficiency LCD displays—such as utility meters, battery-powered clock, watch, GPS and so on—most LCD displays need backlights to be visible in the dim lighting. Most often the backlight is actually at the back of the LCD. In rare cases, this light can be done as front light. The traditional LCD structure with LED backlight shown in Figure 6.

Direct current driving: This is the simple and low-cost way to drive a LED backlight, however, be mindful of the current limit otherwise the LED life can deteriorate quickly. The solution is simply to add a current limiting resistor in the circuit. Current limitation resistors value calculation formula: R = (V0– Vf)/If.Also be mindful of reverse drive, otherwise, the LED chip can break down easily.

LED driver with constant current: The advantage of constant current LED driver is that it will be the best option to use when building your own fixture or working with high powered LED because they avoid violating the maximum current specified for the LEDs, therefore avoiding burnout/thermal runaway. They are easier for designers to control applications, and help create a more consistent bright light.

LED driver with constant voltage: Using a constant voltage LED driver makes sense when using an LED or array that has been specified to take a certain voltage. This is helpful because constant voltage is a much more familiar technology for design and installation engineers. Moreover, the cost of these systems can be lower, especially in larger scale applications.

There are a variety of ways to connect a backlight and LCD module electrically. It can be done with wires that are soldered on the LCD or LCD module. It can be connected using pins, which can be soldered onto the LCD or LCD module. A third way is to use a FPC (flexible printed circuit), which can be soldered or plugged in a ZIF (zero insertion force) connector. And finally, there is the connector method. With this method you use connectors which can be plugged into mating connectors.

As the LED is manufactured via the semiconductor process, there are some color deviations that can be a quality control issue. One way to solve the issue is through a process of selection and sorting after manufacturing the LEDs. The LEDs are sorted into different categories or bins. How this sorting is done and what each bin actually contains is defined differently by each LED manufacturer. The backlight manufacturer can choose from which bin they take the LEDs for backlight color hue.

Some customers might request very fine binning by the LED manufacturer, which can be very expensive since only a very small percentage of the LEDs manufactured would meet the requirements for a specific bin. Figure 7 shows an example of the bin selection from Nichia, the most renowned LED manufacturer in the world. Figure 8 shows the 1931 CIE chromaticity diagram. And Figure 9 shows the color deviations (bin definition) by Cree for a qualified production lot.

In actual LED backlight production, most customers will accept the LED color for two big categories: white with yellowish (warm) and white with bluish (cold). Of course, the LED brightness will also need to be defined. For general application, most customers will accept a brightness tolerance of 70 percent.

It is extremely hard to estimate the LED backlight lifetime or MTBF (mean time between failures) because there are so many variable factors. However, the most important is the temperature on the LED chip. The factors that can affect the LED chip temperature include: surrounding temperature, humidity, driving current, voltage, backlight design (how many LED chips to be used, how close to each other, heatsink design), backlight manufacturing process (type and thickness of adhesive), quality of the LED chip and so forth.

To test the LED life is also very time consuming, requiring at least 1,000 hours. That’s the reason why no LED manufacturers can guarantee LED backlight life and most backlight manufacturers also are reluctant to provide lifespan data. As for LCD manufacturers, they need to discuss it with the customer to understand the applications and provide suggestions. It is normal that the LCD datasheet lists the typical life time and avoids providing a minimum lifetime. From Figure 10, we can see that over room temperature, the current needs to decrease as the temperature increases. At over 85°C, the LED is not usable.

To estimate LED backlight lifetime, you can use ballpark estimation or theoretical calculation. Let’s first examine the ballpark method. To take white LED as example, the nominal biasing current is 20mA. If we use a safe lifetime estimation, we can estimate using Table 1.

Now let’s use the theoretica
