The History of LED Screen

Early Developments of LED technology

You will hardly go somewhere these days without seeing an LED screen being used for anything. The technology that has made this feasible, however, has an interesting and lengthy backstory.

The invention of the LED

Light-emitting diode (LED) technology represented a major advancement in electronics. Inefficient and only lasting for a few thousand hours, incandescent light bulbs were the standard until this development.

Incandescent bulb

The first light-emitting diode (LED) was created by Nick Holonyak, a scientist at General Electric, in 1962. The semiconductor material gallium arsenide was used to create Holonyak’s LED, which emitted a red light when an electric current was sent through it. Energy efficiency, longevity, and dependability were all much enhanced by the LED in comparison to traditional incandescent lamps.

Because of its low power consumption and long lifespan, the LED was first put to use as an indicator light in electronic equipment. This was especially helpful for portable devices that relied on batteries. Yet, as LED technology progressed, novel uses for innovation emerged.

When the first blue LEDs were created in the 1990s, it was a big step forward for LED technology. True color displays required the creation of full-color LEDs, but blue LEDs were far more challenging to manufacture than red or green LEDs. Blue LEDs allowed for the development of high-resolution screens capable of rendering a wide color gamut.

They are a great alternative to incandescent bulbs for both home and business lighting since they save money and energy over time.

First applications of LED

You might find it interesting to know that LEDs were first put to use as indicator lights and numerical displays in various pieces of electronic equipment. Initially, LEDs could only produce a red light, but as semiconductor technology improved, more colors were added. There were now many more places where LEDs could be useful.

Vacuum fluorescent display watch

Digital watches were one of the first consumer products that use LEDs. Because of their compact size and greater accuracy, LED screens were a natural fit for usage in wristwatches. In the mid-1970s, the first LED timepieces hit the market and immediately became a hit.

One of the earliest uses of light-emitting diode technology was in the screens of calculators. When compared to the vacuum fluorescent displays used in early calculators, LED displays were a clear improvement in both efficiency and durability, and their adoption spread rapidly in the late 1970s and early 1980s.


The first outdoor advertising displays using LED technology appeared in the 1980s. To show text and basic images, these displays affixed strips of LEDs on circuit boards. Although they were not as advanced as later advertising displays, their restricted resolution and lack of color rendering did not diminish their usefulness.

Outdoor LED screen

By the late 1980s, surface-mount technology (SMT) had been developed for mounting LEDs on circuit boards, paving the way for the creation of full-color LED screens. This made it possible to create LED arrays with a considerably higher density, leading to displays with a larger pixel count. As early as the early 1990s, full-color LED screens were being used for indoor advertising displays and stadium scoreboards.

The History of LED Screen

Rise of LED screens in the 21st century

You would agree that LED screens have seen a meteoric surge in popularity and application in the twenty-first century, thanks to technological and manufacturing developments that have reduced their costs and increased their availability.

Introduction of SMD technology

The term “surface-mount device” (SMD) refers to a method of building electrical circuits in which components are placed directly onto the surface of a printed circuit board (PCB) as opposed to being inserted through holes in the board. Since its introduction in the 1980s, SMD technology has brought many benefits to the electronics industry that were previously unavailable from using only through-hole components.

Because of the demand for portable, lightweight, and energy-efficient electronics, SMD technology was developed. The amount of functionality that could be crammed into a given area was constrained by the fact that through-hole components were bulkier and required more room on a circuit board. They were also more costly to produce and took longer to make, making them impractical for mass production.

By allowing components to be placed directly onto the Board using automated pick-and-place machines, surface-mount technology solved these problems. Hence, the production process was sped up and costs were cut because holes didn’t have to be bored in the board. Since SMD components are lower in size, higher-density circuit designs became possible, allowing more functionality to be packed into a given space.

Surface mount technology

Compared to through-hole components, SMDs performed better while taking up less space. SMD designs have better high-frequency responsiveness and less noise because the inductance and capacitance of the circuit are reduced due to the shorter distances between components. The thermal performance of SMD components was also enhanced because their flat surface promoted more efficient heat transfer to the Board.

The use of surface-mount devices (SMDs) is now standard practice in the electronics industry, and can be found in almost every piece of cutting-edge consumer technology. SMD technology has allowed manufacturers of anything from smartphones and tablets to automotive electronics and home appliances to fit more features into smaller, lighter, higher performing, and cheaper gadgets.
