What are the Advantages of LED Display?

LED (Light-Emitting Diode) displays have changed how we consume media since it gained popularity in the early 2000s. Before ultra-thin LEDs, the clunky Cathode Ray Tube (CRT) displays were all the rave throughout the 90s. From computers to TV sets, the introduction of LED displays gave way to a more refined viewing experience.

In the early days of its commercialization, one of the widely believed advantages of LED displays was its friendliness to the vision. Some people believe that CRT monitors produce high levels of radiation that affect the eyes. However, no conclusive study has ever been able to prove this.

Unlike this long-running myth, we’ll discuss all the advantages of LED displays based on facts in this blog!

LED display technology

Unlike traditional displays such as the Liquid Crystal Display (LCD) which use fluorescent light to illuminate the liquid crystal solution, LED displays use light-emitting diodes as a backlight. These tiny semiconductors function individually, allowing the console to regulate the brightness and color contrast of the display. The independence of LEDs from one another can be regarded as its greatest advantage over other types of digital displays.

Brightness and Visibility

One of the most noticeable advantages of LED displays is the higher brightness level and visibility. Because LEDs can emit the colors red, blue, and white, LED displays can produce just about every color possible, allowing for a brighter, clearer, and more detailed image reproduction.

Comparison with traditional display technologies

Since fluorescent light can only produce white light, LCDs have limited color accuracy, contrast, and brightness levels. This decreases the quality of the images they reproduce.

Enhanced visibility in various lighting conditions

Through a control system, the brightness level of LEDs can be optimized according to the lighting conditions. Whether it is indoors or out in the sun, LED screens can still display images clearly and legibly.

Suitable for outdoor and indoor environments

Because of their ability to adjust in any lighting condition, LED displays are a popular choice for indoor and outdoor installation. Whether used as a stage backdrop in a concert hall or as an electronic billboard on a building’s facade, you can count on LED screens to still display crisp images.

Energy Efficiency

Backlighting has a significant effect on the energy efficiency of an electronic display. The more efficient the light source is, the less energy the display consumes. Such is the case with LED screens.

Comparison with traditional display technologies

Because the LEDs inside an LED display can be controlled individually, the console can optimize the brightness level, and therefore, regulate energy consumption in each semiconductor. In comparison, the fluorescent lights inside an LCD screen have a fixed brightness brightness level throughout the period the display is on. This means the display cannot regulate the amount of energy it spends.

Longevity and Durability

Gone are the days when fixing an electronic screen meant scrapping the whole thing because of costly repairs. While both LED and LCD screens are repairable, LED gets the upper hand when it comes to the amount of work needed.

Lifespan of LED displays

Studies have shown that LED displays can last up to 100,000 working hours or approximately 10 years. This is significantly longer than the 6.6-year average age that a TV is replaced in the US.

In comparison, fluorescent-backlit displays are only estimated to last 3,000 hours, while neon tubes have a lifespan of 30,000 hours.

Resistance to environmental factors (e.g., temperature, humidity)

While LEDs promise an extended lifespan, several factors can significantly affect them in the long run.

  1. Temperature – LED displays are sensitive to sudden changes in temperature. Excessive heat can hasten the deterioration of internal components, affecting the color accuracy and brightness and even leading to failure to function. Extremely low temperatures can also affect its performance, sometimes causing dimming and flickering.
  2. Humidity – When the LED display is in a high-humidity area, there is a high chance of moisture accumulation inside, leading to possible corrosion and electrical shorts. This can eventually damage the pixels, reduce brightness, and cause the display to malfunction.
  3. Weather Exposure – While there are LED screens built to withstand the outdoors, exposure to environmental factors such as rain, sunlight, and wind can accelerate the wear and tear on their components. For instance, the UV radiation from the sun can damage the protective coating on the LED panel, which may lead to inaccurate color reproduction.

Low Maintenance

Since LED screens are composed of individual LEDs, a damaged LED can be replaced without compromising the whole panel, making maintenance easier and more cost-effective. In comparison, an LCD panel may have 2 or more fluorescent lights. One damaged fluorescent bulb will have a greater effect on the whole display.

Flexibility

LED displays come in various shapes and sizes. This allows them to be used in various applications and locations.

Size and Shape

Unlike traditional displays that are limited to specific dimensions, LED displays can be tailor-fitted to the location or environment where they will be installed. Whether it’s in front of a grocery store or on top of a skyscraper, LED displays can be customized as  needed. This flexibility gets rid of the constraints of space and/or location.

Early LED displays were flat panels limited to flat surface installations. Manufacturers have come up with bendable LED displays that can be used in any layout. From Samsung’s curved LED monitors that changed office setups for the better to LED walls that wrap around posts, these flexible LED displays have made the impossible possible.

Specific Applications

Without any location and space limitations, LED displays can be tailored to your specific preferences. Their high brightness level and consistent color reproduction make them suitable for any application, in any location. Whether it’s for art installations in museums or electronic billboards along a busy street, you can count on LED displays to deliver high-quality images.

Better Color and Image Quality

Color accuracy and image quality are important when it comes to digital displays. LEDs produce bright colors and deep blacks, allowing LED displays to show detailed reproductions of images.

Color Gamut

Since LEDs can emit red, green, and white, LED displays can mix them and produce every color possible. This wide color gamut allows LED displays to have higher brightness levels and show even the smallest details.

Contrast Ratio

Contrast ratio gives images depth. The greater the contrast ratio, the more defined the image is. LED displays offer a high contrast ratio that makes images “come alive”.

Consistency Color and Brightness

The wide color gamut and high contrast ratio allow LED displays to show consistent colors and details from corner to corner. This consistency is crucial for certain applications, as even the slightest difference in details can change the whole meaning of the image.

High Refresh Rate

Response time and refresh rates are crucial for smooth playback. The quicker the refresh rate and the response time, the smoother the display will be. No lags and no blurs.

Refresh rate is the rate your screen updates the images displayed. LED displays have a minimum refresh rate of 60Hz, resulting in clearer images. Meanwhile, response time measures how fast the pixels change colors. LED screens typically have 5ms or less response time. This prevents your content from lagging and having blurry spots.

The quick refresh rates and response time make LED displays the top choice for action-packed content, such as sports. Smooth playback and HD images are crucial in displaying dynamic contents. Whether you’re using it to watch the NFL broadcast or to play dynamic advertisements, you can expect LED displays to deliver outstanding, lossless, images.

Cost-Effectiveness

With energy-efficient LEDs as light source, LED displays consume less power than traditional displays that use other light sources while producing brighter and crisper images. Despite their higher upfront costs, the lower power consumption of LED screens will save you money in the long run. Additionally, their longevity and easier maintenance contribute to the overall savings.

Conclusion

LED displays have changed the media industry for the better. Not only has its invention dramatically improved image quality, it’s also led to innovations within several industries such as in advertising and the arts. As LED technology advances, we can only expect better, bigger, brighter, and cheaper displays in the future.
