Advantages and Disadvantages of LED Displays: A Comprehensive Analysis
LED display screen is a kind of large-screen display product that is widely used at present. However, the advantages and disadvantages of LED display screen are quite obvious. For example, its applicable environment is very wide, that is, it can be used both indoors and outdoors, but it also has the problem of dead light and light falling. Therefore, when we use LED display screen, we must understand its advantages and disadvantages, and then choose it according to our usage and display needs.
Advantages of LED display
1. No splicing obstacles
Although LED display is also spliced by pieces of unit boards, its lamp beads are encapsulated on the unit boards, so it can be seamlessly spliced when spliced together, with good flatness, and no borders like LCD screens, so its brightness is very high and supports adjustment. In a well-lit environment, we can increase the brightness of the LED display to avoid reflections, and in some indoor places with average lighting, we can lower its brightness to reduce stimulation to the eyes, making its application very flexible, which is also a unique advantage of LED display.
2. Waterproof, sun-proof and moisture-proof
LED display screens have the advantages of being waterproof, sun-proof and moisture-proof, so they can be installed outdoors and have stronger environmental adaptability, which is an advantage that other electronic display screens do not have. At present, outdoor advertising screens, traffic light screens, etc. all use LED screens of different specifications.
3. Various specifications and wide range of options
The main parameter of the LED display is the dot pitch, ranging from 20mm outdoor dot pitch to P0.9mm indoor dot pitch. There are many specifications and models. Users can choose the corresponding specifications according to their own applications. The price range is also very large, ranging from a few hundred yuan per square meter to tens of thousands of yuan per square meter.
Disadvantages of LED Displays
1. General clarity
The clarity of LED display is determined by resolution, which is determined by the density of lamp beads. The smaller the lamp beads and the more lamp beads there are in the same area, the higher the resolution, and the clearer the image is. Therefore, some LED displays with large pitch are not as clear as those with small pitch. However, even the LED display with the smallest pitch still cannot reach the clarity of LCD screens, especially when viewed at close range, there will be mosaic phenomenon, so it is not suitable for viewing too close. If you want to achieve better clarity, you can only choose products with small pitch as much as possible.
2. Low contrast
Relatively speaking, the color contrast of LED display is average, so when displaying bright images, the effect it shows is not very bright, especially when reducing its brightness, the whole screen will be gray, not as colorful as LCD screen.
3. The lamp is prone to die, and the after-sales rate is high
The lamp beads of LED display screens often fall off during transportation, installation and use, causing individual pixels to not light up, which will affect the overall image display effect. If you want to repair it, you can only ask professional technicians to come to the door to weld or replace it, which increases the after-sales and later costs.
Therefore, the advantages and disadvantages of LED display screens are quite obvious. We should also know this when choosing. What we want is to give full play to its advantages and minimize its disadvantages.
