How Does the LED Screen Work?
How Does the LED Screen Work? LED screens are everywhere nowadays, and that is because their working principle is much more efficient that those of other technologies.
Let’s examine exactly what these working principles are.
Main Points:
- Display components.
- How Does the LED Screen Work?
- LED Display Function.
- Types of LED screen.
1- Display components:
Display screens contain a number of LED called “Module” cells, which are the same panels used in LED and are known as “pixels”.
They are distributed within LED screens evenly and with the same accuracy, and this makes them provide the best possible quality in displaying content and give the best colors and the best possible viewing angle.
The term LED refers to “Light Emitting Diode”, which means the light-emitting diode, and the electric current passes through this LED, to provide the best possible quality.
One of the important advantages offered by the display screens is energy saving, as it is less energy consuming than the previous generations of screens, while maintaining the best possible quality, and works with high efficiency.
And therefore it is the most widespread and most used, especially in the means of advertising, as it presents your content with the best possible quality as it works to attract target customers to serve you through its glow, brightness of colors and unique quality.
Display screens depend in their work on the passage of electric current passing through them, because they contain light emitting diodes, and these valves are composed of an anode and a cathode, and they are “anode – cathode” and both are separated at two different ends from each other.
With the connection of the electric current, then the atoms are quickly excited from the anode, as it is the highest in energy, and go to the cathode, which is the lowest in energy.
Thus, fusion of the crystal occurs in one direction, and electricity is connected to it as a whole in the form of a photon, and thus one of the light rays that has a specific frequency and accordingly has a wavelength as well as a specific color emitted by the LED, which explains the multi-color ability of the LED.

2- How Does the LED Screen Work?
How Does the LED Screen Work?
Solid-state devices called (LEDs) produce light through the electroluminescence of semiconductors, In a nutshell, this is the process by which a substance emits light after being exposed to an electric current.
Contrary to traditional incandescent lighting, which produces light by using heat energy, LEDs essentially transform electric energy directly into light, reducing the amount of energy wasted through heat loss.
Due to the decreased heat output of LEDs and the fact that they don’t waste energy in the form of heat that doesn’t produce light, LED technology is frequently referred to as “cool light technology” in contrast.
- Understand the size and resolution of LED display:
When selecting the LED display screen, it is necessary to select the appropriate size and resolution according to the use situation and needs, Generally speaking, the size of indoor LED display screen is relatively small, while the size of outdoor LED display screen is large.
When selecting the size, it needs to be determined according to the actual situation on site. Resolution is also a very important parameter, The higher the resolution, the better the display effect, but the higher the cost. Therefore, we need to find a balance between effect and cost.
- Understand the brightness and color adjustment of LED display:
When choose the right LED Screen, you need to understand the brightness and color adjustment of LED display screen, Generally speaking, the brightness of indoor LED display is lower than that of outdoor LED display.
The higher the brightness, the higher the cost In addition, it is necessary to understand the color adjustment function of LED display in order to adjust the color during use to achieve the best display effect.

3- LED Display Function:
How Does the LED Screen Work? The LED screens work on the principle that the output changes when the input is varied but what does this mean?
For understanding this better you need to consider a pixel which is a combination of three different LEDs i.e. RGB.
This means that when only one out of the Red, Green and Blue LEDs, is turned on, the color is different but when more than one of these LEDs is turned on, the combination of these two or three colors generates other colors. Using this method, any color can be obtained on the output.
When the backlight is turned on, white color is produced and when it is turned off, the color turns black.
For producing different colors using this arrangement, the intensity of light for each color filter has to be separately controlled.
For example, when the light from the blue filter is blocked in this RGB combination, the output is yellow, and when the light from the red filter is blocked, the output is cyan.
It is possible to create billions of different colors by varying the diode intensity, The LED screen’s matrix of colored pixels appears as an image when seen from a specific distance.

Transparent LED screen display is a display technology that uses (LED) to produce an image, The light emitted by the LED is projected onto a transparent surface. This transparency allows viewing from both sides of the screen.
Transparent LED screens are ideal for interactive displays and they really make a lasting impression on any audience, Besides, these screens are also energy efficient.
And they are an attractive solution for companies you can use them on billboards, showrooms and other public places for advertisement/display.
- Flexible LED display:
Flexible led screen – (How Does the LED Screen Work?)
LED flexible screen is also called soft module LED display, It is made of a special flexible material, which has strong flexibility and a wide range of applications.
With the development of display technology, more and more application places need to install LED displays for advertising or knowledge dissemination, while ordinary LED displays are limited by many specific places and cannot meet more special application scenarios For example, cylindrical screens used in shopping malls, LED displays of various special shapes, etc.
The development of flexible LED screens has made up for this shortcoming, allowing more special application places to install LED displays.

- Naked eye 3D LED display:
Naked eye 3D LED display – (How Does the LED Screen Work?)
Naked-eye 3D LED display is a display device specially designed for viewing 3D effects with naked eyes.
Compared with the traditional 3D display technology that needs to be matched with 3D glasses to see the 3D effect, the glasses-free 3D technology can directly display the 3D picture, so that the audience can enjoy a more natural, real and comfortable picture without wearing any auxiliary devices.
The screen adopts the angled design, combined with 3D video materials, allowing viewers to appreciate real 3D images with naked eyes.
It is installed outdoors, and like traditional LED displays, it is usually installed on building facades, attracting passing potential customers to stop and watch 3D brand stories or product details, leaving a deep impression on them.

Why choose The High Refresh Rate FOR LED Display?
The LED display is divided into two types: high refresh rate and normal refresh rate, The refresh rate of the high refresh rate display can reach 3840Hz/s, and the normal refresh rate is 1920Hz/s.
When playing videos and pictures, the high refresh rate and normal refresh rate screens are almost indistinguishable with the naked eye, but they can be distinguished through mobile phones and high-definition cameras.
If the requirements are not high or there is no shooting requirement, you can use the general refresh rate, you can choose the, and the price is also affordable.
The price of high refresh rate and general refresh rate is quite different, and the specific choice depends on customer needs and capital budget.
The LED screen with regular refresh rate will have obvious water ripples when taking pictures with the mobile phone, and the screen looks flickering, while the screen with high refresh rate will not have water ripples.
