What does LED stand for?
LED stands for Light-Emitting Diode. This acronym refers to a technology that allows screens to produce lots of light, with little electricity. Along with the technology of a light-emitting diode comes the specific requirements like power adapters, or drivers that assist in regulating voltage. The technology is extremely durable. In the early 90s, it was advanced to include red, green, and blue colored lights, which were developed into what we now use in LED screens.
What are LED displays?
LED displays are flat-panel displays that use individual light-emitting diodes (LEDs) as pixels to create images on a screen. The diodes (thats the D in LED) are electricity conductors that, when a voltage is run to them, light up. When varying voltage is applied to each individual LED, they shine at various levels of brightness, creating images. There are multiple types of LED display panel types with differences that make them better for different usages. These types include lightbar, dot matrix, 7-segment, 14-segment and 16-segment.
When were LED displays invented?
The first LED display was invented in by an engineer at General Electric. Due to technical limitations of the time, it could only produce monochrome red images. Despite continuous development over the decades, full-color LED screens werent available until the late s. You might remember from early science lessons that incandescent light, you know Edison, is a result of a heated filament. Well, the light produced by an LED is actually considered cold light because it is generated within the diode itself. This is a much more effective and efficient way to produce light.
Are LED displays good?
LED is the best choice for a variety of screens for multiple reasons. First, LED is extremely energy-efficient. Its low energy consumption makes it ideal for rechargeable handheld devices like phones, tablets, and laptops. Second, LEDs can be arranged in very dense arrays (thousands of cells very close together), which means they allow for incredibly detailed, crisp static and moving imagery. Third, LED screens produce very bright images, which makes them fantastic for outdoor use and for viewing at a distance. They can be illuminated brightly enough for viewing at night or in bright sunlight.
Is LED better than LCD?
LED is a type of LCD! LCD stands for liquid crystal display. The crystals are what determine how much illumination is displayed in each pixel (or diode, in the case of LED) at any given time. As a broad category, most LCDs have made way for LEDs. Instead of using CCFLs (cold cathode fluorescent lamps) to illuminate each pixel, most modern LCDs use LED.
Is an LED screen worth it?
Yes, an LED display is worth the investment. When youre trying to capture the attention of a large crowd, theres no other display on the market today thats as bright and captivating. LED displays can be used in almost any weather condition, at any time of day. They dont consume a lot of electricity to power their high refresh rate and dazzling color. Plus, depending on how often youre using your LED screen, they can last a very long time.
How do I know which LED display is right for me?
Internet research can only get you so far. When youre serious about an LED display screen purchase, reach out to the experts at Insane Impact. With an understanding of your goals and use cases, we can ensure you make the perfect choice of LED display.
Screens are one of those things we all use, but few of us actually understand how they work.
At Insane Impact, LED screens are what we do. We build custom solutions to create unforgettable experiences and it all starts with a little light.
UNDERSTANDING COLOR
Red, green, and blue (RGB) are the three basic light colors that make up every visible color. LED screens have many red, green, and blue LEDs expertly placed to create the picture you see. Mixing hue (level of color) and saturation (lightness or darkness) those three colors of LEDs make any color and image.

THE VIEWING EXPERIENCE
Resolution is a combination of the number of pixels and how close they are together. Heres how it works. LEDs are grouped in RGB groups. The grouping is called a pixel. The distance between pixels is called pixel pitch.
Still with me? An average high-definition television will have a resolution of p x p with anywhere between 3mm to 6mm pixel pitch. That means there are 2,073,600 pixels and they are roughly 3-6mm from one another.
However, the further away you are from a screen the fewer pixels and higher pixel pitch you need. Thats the way our eyes work. Looking at a MAX , our 23 ft by13 ft screen, is a lot different for our eyes to take in than 72 in television. You view a television anywhere from 10 ft to 30 ft away, but youd view a 23 ft screen across a football field. It makes a higher resolution unnecessary because your eyes wont really be able to tell the difference at a distance.
The next functional component of a screen is called NITS. Nits measure the brightness of the screen. You can have all the pixels as close together as possible, but if you dont have the proper brightness you wont be able to see them. When it comes to brightness, the brighter the space you are viewing the greater NITS needed. We recommend a minimum of NITS for viewing in direct sunlight.
DIGITAL CONTENT
All of the functional components of your screen are only of value if your content is designed for it. For example, you wouldnt try to view a 4k blu-ray on a high-definition screen. The resolution of the content is too much for the screen. The best viewing experience is when the content is designed to be compatible with the way it is being displayed.
Did you know graphic designers and photographers use different color types depending on how it will be viewed? They actually design in RGB for digital content so that it will appear properly on an LED screen.

LED Screens 101: Your Comprehensive Guide
LED screens and walls are a fantastic way to captivate viewers and add excitement to a variety of applications. Their high flexibility allows for creative incorporation into any space, event, or occasion, connecting viewers to your brand or message in a memorable way. Understanding LED screens is crucial to making the most meaningful impact, whether enhancing your business environment, hosting an event, or designing a unique installation. This blog will guide you through everything you need to know about LED screens, from how they work to their numerous applications and advantages.
What is an LED screen?
An LED screen is a type of display technology renowned for its bright, vibrant visuals and versatility. It consists of numerous small diodes emitting light to create images, making it ideal for indoor and outdoor applications. LED screens are widely used in various settings, including retail stores, stadiums, airports, and corporate events, thanks to their ability to deliver precise and dynamic content. They are known for their durability, energy, efficiency, and ability to operate in diverse environmental conditions. Additionally, LED screens can be customized in size and shape, providing flexible solutions for creative and impactful visual presentations.
What does LED stand for?
LED stands for Light-Emitting Diode. Each diode is a semiconductor device that produces light when an electric current flows through it. Unlike traditional light sources that use filaments or gas, LEDs are known for their energy efficiency and long lifespan. Their ability to emit bright, clear light while consuming less power makes them an ideal choice for modern electronic displays.
How do LED screens work?
LED screens work by using an array of light-emitting diodes arranged in a grid formation. Each diode acts as a tiny light source that can emit specific colors when an electrical current passes through it. These diodes are controlled individually to produce various colors and brightness levels, creating detailed images and videos. Unlike older display technologies that use a single backlight, LED screens generate light directly from the diodes, allowing for higher contrast ratios, better energy efficiency, and improved overall image quality. The diodes can be combined to form pixels, which are then organized to display the desired visual content with precision and clarity.
The History Behind LED Screens
The development of LED technology dates back to the mid-20th century, with the first practical visible spectrum (red) LED created in by Nick Holonyak Jr. Over the decades, advancements in semiconductor materials and manufacturing processes have culminated in the development of LEDs that emit various colors and higher intensities of light. Today, LED screens are integral to many industries, providing bright, efficient, and versatile display solutions.
