In this article, we discuss five advantages and disadvantages of LED displays that you should know.
LED displays have a long lifespan that outlives traditional light bulbs, which makes it one of the most popular advantages of LED displays. Some LEDs can reach 50,000, while other manufacturers claim that it can even go as high as 100,000 hours. With this long useful life, the need for frequent replacements is reduced. It saves you thousands of maintenance costs and minimizes disruptions to operations, making LEDs an attractive choice for commercial, industrial, and residential applications.
LED displays also feature a unique form factor compared to traditional light sources. Generating light doesn&#;t require filaments or tubes. LEDs only generate light when interacting with electricity. Hence, LEDs are durable because they are not fragile and have a stronger form factor. Even in harsh environments, manufacturers can tailor-fit LED screens to withstand harsh conditions.
Aside from its long useful life, LED displays are also more viable for external use. It can withstand harsh environmental conditions without affecting its performance. It can still generate high lumen output while exposed to these conditions. LEDs can also resist water and dust particles with the proper IP rating. That&#;s why it&#;s more suitable for outdoor settings, such as street lighting, signage, and architectural illumination.
Another one of the advantages of LED display is that it is for gaming. Gamers nowadays are craving for a high refresh rate and excellent picture quality. Monitors are often conflicting with refresh rate and quality. LEDs provide excellent brightness and color accuracy for clear and vivid picture quality for gaming. Whether playing first-person shooter (FPS) games or role-playing games (RPGs), LED can generate high contrast ratios and provide fast response times.
Higher refresh rates are beneficial for FPS gamers since it enables them to react quickly to in-game movement. If coupled with the right GPU, there will be minimal ghosting and delays. Moreover, high contrast ratios and excellent picture quality are beneficial for RPG and story-type games because they give gamers outstanding video output.
Aside from monitor quality, LEDs also improve your gaming setup. Vibrant and customizable lighting effects installed in your gaming room, mancave, or home office enhance not only the gaming experience but also the overall vibe of the place. LEDs can create immersive environments through ambient lighting, lighting patterns, and reactive lighting that synchronizes with in-game events. LED monitors also consume less power than traditional LCDs. If you have a well-invested home office and gaming setup, LEDs have minimal electricity consumption and require minimal cooling.
With LEDs, manufacturers can create different designs and forms. Through surface-mount technology and chip-on-board structures, manufacturers can create different kinds of LED products without worrying about the size. Have you wondered why LED strip lights were possible? It&#;s because COB LEDs can be compressed into small form factors without affecting their light outputs. Aside from that, you can bend and twist these strips without breaking the chips.
Because of this flexible feature, LED products can be ultra-thin and lightweight, which makes them suitable for portable devices such as flashlights and smartphones. That&#;s why flexibility is one of the advantages of LED displays. Overall, there are countless possibilities with LEDs. Before its popularity, these lighting products weren&#;t possible even with LCDs. In fact, LCDs are very sensitive to pressure, making them less suitable for purposes where LEDs excel greatly.
Additionally, LED displays are modular. They can fitted and customized to different shapes and sizes. Whether it is a vertical, horizontal, or spherical wall, LED can be customized for that use. It offers unparalleled flexibility in terms of design and configuration, allowing users to tailor their visual experiences to suit specific requirements and environments.
Many people like LEDs because of their color accuracy and picture quality, making picture quality one of the advantages of LED displays. It is suitable for video and photo editing, especially if appropriately calibrated to produce realistic and accurate colors. The brightness capabilities of LED also contribute to its overall picture quality because it can produce vibrant and eye-catching output that can withstand outdoor lighting conditions. Even if you place an outdoor LED in broad daylight, you can still produce crisp, clear, visible picture quality.
With COB and SMD LED technology, users have better viewing angles because of compact LED form factors. The wide viewing angles that LEDs can provide are one of the great advantages of LED displays. When LED chips are compact, they produce denser light and widen the viewing angles further. Compact LEDs ensure that light is emitted evenly and that there are no dim areas in some parts of the screen.
The unique designs of COB and SMD LED enable better picture quality, minimize color and brightness distortions, and ensure bright images in all parts of the screen. Even if you&#;re off-center, you&#;ll still have a good view of what&#;s on the screen without discolorations or distortions. Unlike traditional displays, LEDs emit light directly from individual diodes. It doesn&#;t require polarizing filters to show images on the screen. This method allows LEDs to maintain consistent brightness and color accuracy across a wide range of viewing angles.
Of all the disadvantages of LED display, price is the leading one. It is common for LED products to be pricier than their LCD counterparts. Because of its energy-saving capabilities, LEDs require a manufacturing process different from that of other screens. It requires the use of gallium, indium, and other rare earth elements that can be expensive. With its high raw material cost, LEDs are expected to have a higher price tag.
Aside from its expensive raw materials, the sophisticated manufacturing process of LEDs also affects the price. It requires semiconductor fabrication facilities. These facilities have a lot of overhead, which prompts manufacturers to raise the price. Besides, the upfront investment can be hefty as well.
On top of that, LEDs offer a lot of flexibility, features, and capabilities. It has dimming capabilities, color-changing options, and compatibility with smart home systems. Smart LED devices have circuit boards that can be programmed and controlled using software or mobile apps. That&#;s an added cost for the manufacturers just to offer that functionality.
And finally, manufacturers leverage their patented technology for LED&#;s long lifespan. While not all LEDs are the same, manufacturers invest in different technologies to prolong the lifespan of LED products.
LEDs emit denser lights than LCDs, incandescent lights, and fluorescent lights. However, because of its outstanding light density, it can contribute to light pollution. Light pollution occurs when there are too many man-made light sources, which block and disrupt natural light from the environment. Too much artificial light can also affect sleep cycles and eye health.
Stargazing will not be possible when there is too much man-made lighting present. It blocks the view of stars and creates a hazy night sky. While brighter surroundings aren&#;t inherently bad, they can have a long-term effect on the people and animals living in such areas. Hence, brighter light outputs can be one of the disadvantages of LED displays.
Another one of the disadvantages of LED displays is their cost. Manufacturers say that you can save money from LED lighting. Well, that&#;s true in all aspects. However, many consumers forget that LEDs also have high maintenance costs, specifically in repairing and replacing LEDs. One factor contributing to potential maintenance expenses is the complexity of LED displays, particularly in large-scale installations or specialized applications. In LED systems, when one pixel dies in a chipboard, sometimes the only remedy is to replace the whole chipboard, even if only one or two LED chips are busted.
Moreover, improper use of LED can lead to higher maintenance costs. If you buy an indoor LED, do not put it outside or expose it to the elements. Without the required IP rating, LEDs are prone to damage caused by environmental factors like moisture, dust, and temperature fluctuations.
Aside from that, suppose you want to reposition a fixed LED structure. The cost of LED retrofitting can be significant, potentially impacting the overall cost of ownership and lifecycle maintenance expenses. Hence, it&#;s best to decide where you&#;ll place the LED structure to avoid reinstallation costs.
Eye health is a concern in this day and age. As displays get better and brighter, the human eye may have trouble adapting and coping with extreme light sources. The high intensity and brightness of LED light are harsh and glaring to the naked eye, especially during extended periods without adequate breaks and eye protection.
The blue light from most LED lights can also cause eye strain and interrupt sleep patterns. Without appropriate light-adjusting software or protective lenses, the naked eye will be at risk of eye fatigue. Aside from that, flickers, glares, and strobing effects can lead to discomfort, headaches, and difficulty. People with epilepsy will be at a higher risk of epileptic seizures if there are strobing effects.
While we&#;ve discussed earlier that LED displays are durable, take note that they&#;re not indestructible. If not correctly used, it is still susceptible to damage. That&#;s why getting an LED product with the appropriate IP rating is important to ensure that it can withstand harsh environmental conditions such as high temperatures, moisture, UV radiation, and dust particles.
Without the proper fixtures and protections, LED displays are at risk of physical damage, corrosion, and electrical failure, which will entail higher repair costs if it&#;s still repairable. Otherwise, you&#;ll have to buy a new unit if it&#;s beyond repair. An IP65 LED screen is ideal for outdoor use because it can withstand wind, light rain, and debris. Adequate housing surrounding the LED&#;s body is also needed to add an extra layer of protection, even if the manufacturer guarantees its durability.
In conclusion, LEDs are excellent for their many uses and applications. The quality that it gives is unrivaled because of the value it gives to consumers. Though we have a lot of good things to say about LEDs, it still has its disadvantages. We recommend weighing the factors before deciding so that you can fully maximize your resources and get the best screen for your needs. We hope this article about the advantages and disadvantages of LED displays helped you understand each in great detail.

Advantages of LED display
1. No seams
The unit of the LED display is the unit board, which is distributed with different sizes, different spacing, different number of lamp beads, this lamp bead is packaged by three color chips, and the light is controlled by the chip behind the unit board. If you want to assemble into a large screen, you only need to splice multiple unit boards together, and it has no splicing obstacles, and there is no seamless seam between the boards and boards, and there is no border like the LCD splicing screen, and naturally there is no seam trouble.
2. Waterproof and sunscreen
The special composition architecture ensures that the LED display can reach the level of waterproof and sunscreen, so we see that some outdoor displays are LED.
3. High brightness and adjustable
The brightness of the LED display can be freely adjusted to meet the display needs of different lights, such as outdoor facing the sun and facing away from the sun, its brightness is completely different, in order to ensure that the screen is clearly visible, it is necessary to adjust its brightness.
Disadvantages of LED display
1. Low resolution
The resolution of the LED display is much lower than the resolution of the LCD splicing screen, even if its minimum spacing product its resolution can not be compared with the LCD splicing screen, so the most direct consequence is that the LED will have a mosaic phenomenon when displaying the image, and the text will be composed of small squares when looking closely, and the picture clarity is worse.
2. Low contrast
Low contrast will lead to the light and dark and level of the picture is not rich enough, so the picture presented is not good, which is not as good as the LCD splicing screen.
3. High after-sales rate
The lamp beads of the LED display will fall off, dead lights and other phenomena, and they are relatively frequent, which increases the after-sales rate and costs.
4. Need auxiliary heat dissipation
If installed outdoors, the temperature of the LED display will sometimes be relatively high, and an air conditioner must be installed in order to achieve rapid heat dissipation, which is equivalent to an additional cost.
The main function of LED display
(1) Maximum brightness
In the industry "standard" discussed at the end of last year, there were no clear characteristic requirements for the important performance of "maximum brightness", which was in line with GB/T1.2-. In "Standardization Work Guidelines, Part 2: Methods for Determining the Content of Normative Technical Elements in Standards", "5.4.3 Values determined by suppliers", it is mentioned that "if the diversification of products is allowed, some characteristic values of the product may not be specified (although these characteristics have a significant impact on the performance of the product)".
Because the use environment of LED displays is very different, illuminance (that is, the average person calls ambient brightness) is not the same, so "for most complex products, as long as the standard specifies the corresponding test method, the supplier provides a list of performance data (product information) than the specific performance requirements given in the standard." These are in line with international standards, but this also leads to unrealistic comparisons in competitive bidding, which users do not understand, so that the "maximum brightness" required in many tenders is often much higher than actually needed.
Therefore, it is recommended that in order to guide users to correctly understand the performance index of the "maximum brightness" of the LED display, it is necessary for the industry to give a guide: in some occasions, in the use of different illuminance environments, what value can the brightness of the LED display meet the requirements.
(2) Primary color dominant wavelength error
Changing the primary color main wavelength error index from "primary color wavelength error" to "primary color main wavelength error" can better explain what characteristics this indicator reflects LED display. The dominant wavelength of color is equivalent to the hue of the color observed by the human eye, which is a psychological quantity and an attribute that distinguishes colors from each other. And the performance requirements specified by this industry standard, literally, users are unable to understand that it is an indicator that reflects the color uniformity of the LED display. So, is it to guide the user to understand the term first and then understand the indicator? Or first recognize and understand the LED display from the customer's point of view, and then give the user-understandable performance characteristics? As mentioned earlier, GB/T1.2- (Standardization Work Guidelines Part 2 Methods for Determining the Content of Normative Technical Elements in Standards) one of the principles for product standard development is the "performance principle": "Whenever possible, requirements should be expressed by performance characteristics, not by design and description characteristics, and this method leaves the greatest room for technological development". "Primary color dominant wavelength error" is such a design requirement, if "color uniformity" is used instead, there is no LED that defines what wavelength.
For users, as long as you ensure that the color of the LED display is uniform, without considering what technical means you use to achieve it, leaving as much room for technological development as possible, which is greatly beneficial to the development of the industry.
(3) Duty cycle
As stated above, the "performance principle" "Whenever possible, requirements should be expressed by performance characteristics, rather than by design and description characteristics, an approach that leaves the greatest scope for technological development". We believe that "duty cycle" is purely a design technology requirement and should not be used as a performance indicator of LED display product standards; Everyone knows very well that there are users who care about the drive duty cycle of the display, they care about the effect of the display, not our technical implementation; Why should we create such technical barriers ourselves to limit the technological development of the industry?
(4) Refresh frequency
From the measurement method of the "Standard", it seems to ignore the real concerns of users, and it does not take into account the different driver ICs, driving circuits and methods used by various manufacturers, resulting in difficulties in testing. For example, the full-color screen bidding of Shenzhen Stadium, in the sample test of experts, the test of this indicator has brought many problems. The "refresh rate" frame shows the reciprocal of the time required, and the display is treated as a luminous light source, which is the flickering frequency of the light source. We can use an instrument similar to a "light frequency meter" to directly test the flicker frequency of the light source of the display screen to reflect this indicator. We have done this test, using an oscilloscope to measure the LED drive current waveform of any color to determine the "refresh rate", measuring 200HZ under white field; At the low gray level such as level 3 grayscale, the measured frequency is as high as a dozen KHZ, and measured with PR-650 spectrometer; WHETHER IN WHITE POINT, OR AT GRAYSCALE LEVELS SUCH AS 200, 100, 50, THE FLICKERING FREQUENCY OF THE MEASURED LIGHT SOURCE IS 200HZ.
