WHAT IS AN LED SCREEN?
An LED screen is a display device that uses light-emitting diodes (LEDs) as pixels. LEDs are much more efficient than traditional incandescent bulbs and can produce much brighter light while using less energy. LED screens are often used in outdoor advertising and as public information displays, but they are also finding their way into homes as televisions and computer monitors.
The benefits of LED screens over traditional LCD or plasma screens include:
Brighter image: An LED screen can be up to three times as bright as an LCD screen of the same size, making it easier to see in sunlight or other bright conditions.
More energy efficient: LEDs use less electricity than either LCD or plasma screens, so they can save you money on your energy bill.
Longer lifespan: An LED screen can last for up to 100,000 hours before needing to be replaced, which is about 10 times longer than an LCD screen.
SHORT HISTORY OF THE EVOLUTION OF LED SCREEN
LED screen technology has revolutionized the way we watch television. The first LED screens were used in the early 1970s and they were very expensive. In the 1980s, LED screens became more affordable and they were widely used in electronic devices such as calculators and watches. In the 1990s, LED screens were used in mobile phones and PDAs. Today, LED screens are used in a variety of electronic devices including televisions, computers, laptops, and tablets.
The first LED screens were made of large arrays of light-emitting diodes (LEDs). The LEDs were mounted on circuit boards and powered by batteries. These early LED screens were very bright but they consumed a lot of power. In the 1980s, thin-film-transistor (TFT) technology was developed. TFT-based LEDs use less power than traditional LEDs and they can be manufactured on thinner glass substrates. This made TFT-based LEDs more suitable for use in portable electronic devices.
In the 1990s, organic light-emitting diode (OLED) technology was developed. OLEDs are made of organic materials that emit light when an electric current is applied to them. They are thinner and lighter than traditional LEDs and they can be manufactured on flexible substrates. This makes OLEDs well-suited for use in portable electronic devices such as mobile phones and PDAs.
Today, there are two main types of LEDs: organic LEDs (OLEDs)
HOW DO LED DISPLAYS WORK?
LED screens work by using an array of light-emitting diodes (LEDs) to create an image. LEDs are small, energy-efficient light sources that can be used to create a wide range of colours and brightness levels. When used in an LED screen, the LEDs are arranged in a grid formation and controlled by an electronic signal. This signal tells the LEDs when to turn on and off, and what colour to display. By carefully controlling the timing and intensity of the LED signals, a high-quality image can be displayed on the screen.
IMPORTANT TECHNICAL TERMS TO KNOW
-Pixel: A pixel is the smallest element of an image that can be individually processed in a video display system.
-LED: LED is an acronym for “light emitting diode.” LEDs are semiconductor devices that emit light when an electric current is passed through them.
-Luminous Efficiency: Luminous efficiency is a measure of how well a light source produces visible light. It is usually expressed as a percentage of the light output from the source compared to the input power consumed by the source.
-Lumens per Watt: Lumens per watt (LPW) is a measure of how efficiently a light source produces visible light. It is calculated by dividing the number of lumens produced by the source by the power consumed by the source in watts.
-Color Temperature: Color temperature is a measure of the colour of light emitted by a light source. It is usually expressed in Kelvin (K), with lower temperatures being warmer (more orange/red) and higher temperatures being cooler (more blue).
WHAT ARE THE DIFFERENT TYPES OF LED SCREENS?
There are a few different types of LED screens available on the market. Here is a quick run-down of the most popular types:
- Indoor LED screens: These are typically used for indoor events such as trade shows, conferences, and concerts. They are often rentals and can be assembled quickly.
- Outdoor LED screens: These are larger in size and used for outdoor advertising, sporting events, and live concerts. They are weather-resistant and have a longer lifespan than indoor screens.
- Flexible LED screens: These are made with a flexible material that can be curved or shaped to fit any space. They are often used for temporary installations or in hard-to-reach places.
- Transparent LED screens: These see-through screens can be used for store windows, product displays, or art installations. They create an interactive experience that engages passersby.
