Commercial LED screens are “magic LED screens” that people can see everywhere.

It has not only stunning visual effects but also displays unlimited creativity and stimulates people’s consumption impulse.

But people know very little about it.

How did commercial LED screens come into being and have been developed step by step?

How does it gradually sweep the market and become an important advertising medium that is popular all over the world?

Why is it popular with people?

It is so mysterious and full of energy that it will last forever; let’s talk about its story.

To trace the source of commercial LED screens, we must start with the birth of LED (light-emitting diode).

01, From Grassroots to Explosion: LED Counterattack

(1) Birth of a light-emitting diode

Do you believe it? 

LEDs all over the world were not even like an incandescent lamp?

This is not a rumor; it is the case.

Although the LED screen is now in the field of vision, its development has not been smooth.

LED was born in the name of nobility, but it didn’t get much attention. 

Instead, it fell into silence.

In 1962, the famous American General Electric Company developed the first batch of light-emitting diodes.

But they have limited brightness, which is 150 times lower than white incandescent.

Such products do not seem to be worthy of further research and, therefore, are not valued.

However, the value of LEDs has not been sunk. 

Instead, it was discovered by Monsanto and HP. 

In 1968, a new reddish-color LED was produced.

Later, it was discovered by other scholars and got continuous research.

Since then, continuous and uninterrupted scientific research results have led LED to fast-track car development.

Its luminous efficiency has been increased by ten times every ten years, and it has increased by more than 1,000 times in just 30 years.

In the beginning, the efficiency of LED was not even less than one percent of that of ordinary incandescent lamps, but after a few decades, it had a surprising increase.

This is a good example of a counterattack from grassroots to explosive models.

Although the devoloping is fast, this LED can only emit red ochre light.

In the ’70s, improved red and green LEDs and newly emerged green LEDs entered the market.

Slowly, orange-red and yellow-yellow LEDs appeared one after another and were used for commercial purposes.

With the introduction of Japan’s Toshiba Corporation and some Taiwanese companies, LEDs are continually being updated.

In the 1990s, the luminous efficiency of LEDs finally surpassed the incandescent lamps that were once 150 times their own, and the light intensity even reached a candle level.

In addition to the brightness, its color has also covered from the simple red and blue to the entire visible spectral range.

This also laid the foundation for the emergence of LED screens.

(2) The advent of LED screens: from the small components to the unlimited possibilities.

Even though LED has achieved rapid development, the period of its real explosive growth has not come yet.

People don’t know; such a simple light fixture will develop into a super screen that attracts the world’s attention in the United States Times Square in the future:

Nasdaq full-color LED screen.

This screen has an area of more than 1,000 square meters and is made of 19 million ultra-bright blue, green, and red LEDs.

Because it is located in the heart of the global commercial nuclear industry, this screen has been hailed as the “first LED screen in the world.”

Many companies are proud to be on this LED screen.

So, when did the glorious LED display screen appear?

The LED screen is composed of a light-emitting diode dot matrix module or a pixel unit.

In popular terms:

A plurality of LED elements are arranged regularly, and after being packaged, various anti-water treatments such as anti-water treatment are performed, and then LED modules are formed.

It became the LED screen we saw.

From single color LED screen to colorful LED screen

From LED fixtures to LED screens, this “jump of the century” was born in the mid-1980s.

First, single-color and multi-color displays came out, but this is just a simple application, such as a text screen and an animation screen.

Because the brightness is normal, the size is limited, the display content is single, and because the display effect is limited, it was only used indoors at first.

From picture to text screen to video screen, from indoor to outdoor.

By the early 1990s, the development of electronic computer technology and integrated circuit technology had brought “runners” to LED displays in the early stages of development.

The video technology of LED display is finally realized, and the TV image can be directly displayed on the screen, realizing a huge leap forward.

Since then, LED screens have been truly optimized in all walks of life, industry, and industry chain.

In this process, the LED display screen is gradually going outdoor.

The segmented market promotes a specialized LED display.

With the development of craftsmanship, different pitches began to divide.

Driven by industry segmentation, LED display products used in various specific scenarios appear.

Various LED screens, including Wumei stage screens, traffic information screens, and stock market information LED screens, have come out one after another.

The development of commercial advertising has also led to new uses for LED screens.

Various well-known brands are seeking to gain more consumers, and the huge market demand has driven LED screens to change.

Gradually, commercial advertising screens came into being.

It is widely installed in streets, alleys, commercial buildings, and used for advertising.

This has also become the most important use of LEDs, which can bring benefits.

This is the main character of today: commercial LED screen.

The Nasdaq full-color LED screen mentioned in the previous article belongs to this category.

(3) Where will the LED display screen go in the future?

People are obviously not satisfied with the existing display effects of LED displays.

In the wave of market competition and innovation, the integration of LED display screens with AR, VR, 3D technology, and sensing technology has become a general trend.

The most typical case is the emergence of “interactive floor tiles.”

The manufacturer combined the related LED display and sensing technology to create this new product, giving everyone a new feeling.

It can be predicted that after the arrival of 5G:

Long-range, intercontinental high-definition real-time broadcast;

Ads that can be interactive through limbs and expressions;

Through sensing and recognition technology, big data push smart advertisements suitable for consumers to see these may become a reality.

The future of commercial and advertising LED screens is possible.

02, What is the difference between LCD and LED?

In the history of LED screen marketization, I have faced many competing products.

However, there is one of them, which is often confused with LED screens due to naming and similar effects.

This is the LCD display.

When it comes to LED displays, people are asking:

What’s the difference between them? Why choose an LED display?

The lower face is explained through several dimensions.

(1) Different operating principles.

The full name of the LCD screen is Liquid Crystal Display.

It has a separate light source, which is refracted layer by layer to form an image. It can be interpreted as a kind of “subtraction.”

The full name of the LED screen is Light Emitting Diode.

After receiving electricity, electrical energy is directly converted into light energy. Each pixel is composed of three color beads, red, green, and blue.

Which color is more bright, Which LED light to increase the brightness.

Therefore, it can be interpreted as a kind of “addition.”

(2) Different display effects.

LED brightness has more advantages:

The response speed of the individual elements of the LED display is 1000 times that of the LCD, so the brightness range is wider.

The light of the LCD display screen is filtered through layers. 

What people see is the weakened light. 

The brightness is not as high as the former.

LED viewing angle is wider:

The LED screen can provide a viewing angle of 160 degrees and can be viewed in a variety of positions.

LCD screens are difficult to reach.

LEDs are more colorful and bright:

The LED display can be self-luminous, and each pixel is three-color light, the display effect is even more full.

The LCD display has a backlight layer, and the light will be refracted, so the color is not as bright as the LED.

The LED screen can be seamlessly spliced and more beautiful.

The LCD screen is spliced, but there are gaps. Visually, there are black lines, which affect the viewing effect.

(2) different life and quality.

LED power consumption is much lower and more power-efficient:

Each pixel of the LED screen works independently, and a certain color is required to light up an LED;

Besides, it uses a low-voltage scan drive, which consumes less power;

The use of high-voltage diodes saves energy, protects the environment, and provides high brightness.

Once the LCD screen is turned on, the entire backlight layer needs to be turned on;

And it also uses cold cathode lamps, which consume more power.

LED life is longer:

The LED display usually supports about 100,000 hours, and it can be used for several decades under normal circumstances.

LCDs are relatively short.

The LED screen is more water-resistant and more durable:

The LED screen has a longer service life, and when the module is done, it is coated with materials such as anti-proof paint, which can effectively prevent water.

Due to the structure and service life of LCD screens, LCD screens have poor water resistance and are not as durable as LEDs.

(4) why buy an LED screen, instead of an LCD screen.

LED screens are more suitable for commercial advertising screens.

The LED screen has higher brightness, a larger viewing angle, and optional large pitch. 

It can still be clearly seen under strong light and long-distance.

Due to better endurance, it is very suitable for outdoor use.

It is installed on the outside of the building and accepts strong wind and rain, and still has excellent performance.

This feature is in line with the intention of more people to see commercial and advertising, and the cost of long-term use.

However, the LCD screen is not as good as the former in terms of brightness and viewing angle, it is more fragile, and the cost is higher.
