Spirit & Success, Together, Enbon led display screen
Language
Defined as one of the epitomes of human successes and advancements, there is no doubt that technology has played a huge role in improving our daily lives. Fifty years ago, there was no possible way you could
connect with a friend or family living on a different continent. For sure, the telephone was already invented, but it was very expensive to call someone else in your hometown, leave alone in a different country or continent. Having access to the telephone was considered a luxury few could afford.
Now, I can quickly pull out my phone or laptop and virtually connect with friends and loved ones, wherever they are. Talk about the world becoming one, a small village
Connectivity brings us together. We find it important always to entertain ourselves and stay updated with the latest events. The invention of the television has precisely facilitated these desires. Luckily, there have been several advancements in manufacturing a television to ensure customer satisfaction. The images have become brighter in recent years, and the sound quality is more concise.
We shall look closely at LED screens, a major advancement in the TV industry. We shall also take a closer look at how its made, how it works, and how much power it uses
What is LED?
LED is a term that stands for the light emitting diode. An LED screen is a giant screen made up of little light emitting diodes placed closely together. The diodes are used as pixels for a video display and are relatively bright, so they can also be used outdoors.
Compared to other screens previously made, LED screens are much more energy efficient. The diode emits light when flowing through two precisely coated semiconductors. The semiconductors are silicon, which helps the diode emit light efficiently.
LEDs were first invented in 1962. For the first decade, they were majorly red. Blue LEDs only arrived commercially around 1980. As years went on, more and more developments were made to the LED screen to make it more efficient and energy-saving.
LED is also energy efficient because it emits almost zero heat. Therefore, LED screens can cool more efficiently. An LED is made up of solid materials with immobile parts. It is often molded into transparent plastic, which guarantees high durability.
LED converts electric energy to light, while traditional incandescent lighting converts heat energy to produce light. Therefore, LED is referred to as "cold light technology" because of how efficiently it saves energy. On the other hand, traditional incandescent lighting would produce a substantial waste of energy because of heat loss.
How an LED display works
An LED display comprises red, blue, and green LEDs. The diodes are close spaced and are mounted in a fixed pattern. Furthermore, the colors combine to form a large pixel. Billions of colors can be formed by changing the intensity of the diodes. The array of colored pixels forms an image, which can be viewed from a distance.
How much power does an LED display use?
LED is generally known to be an energy-saving type of technology. However, three major factors would determine the amount of power consumed by the diodes in an LED display:
Brightness – the images must be easily visible and brighter. However, the light from the display must not deprive you of sight, even though it is bright
Type of display – there are various types of displays. For example, the power consumption of an indoor display would be different compared to the power consumption of an outdoor display. If the display is outdoor, it must be brighter during the day compared to nighttime
Usage – LED displays images by turning on and adjusting the brightness of the colored diodes. If the display is entirely white while the text is black, the display would require more illuminated diodes. Additionally, the display would require less power than when white text is displayed on a black background.
How LED screens are made
Conducting a technical study
A unique professional department conducts a thorough study. The department is highly versed with LED screens and has years of experience. The study aims to look at the technical concepts required to perform a fresh order
Structural design
The frames are designed from scratch. This is done to adapt to the features and sizes required by the customer
Assembling of structural components
The pieces inside are placed precisely according to a certain pattern. A laser is then used to align the inside pieces perfectly. The structure is assembled in a very accurate manner to ensure that there is no separation in the entire unit
Electronic components
This is the most important part of the entire process. The LED and electronic equipment are assembled and programmed to ensure that only parts corresponding to a certain order are used.
Assembly of electronic components
The manufactured circuits are then assembled to create complete panels. These panels are fully functional and able to reproduce a full-color image
Adjustment and tuning
The LED panels are adjusted to the light. This is done to ensure that color and sharpness are the same on the whole LED advertising screen. Photoelectric sensors are used to measure the chromocyte patterns and adjust and memorize every LED component.
General assembly
Structural frames and parts are assembled. The assembling process is carried out to form complete units, which can reproduce videos
Assembly test
The screen is activated, and a thorough testing process is carried out to determine possible flaws and necessary adjustments
Image test
Here, several test videos are reproduced. Eventually, everything is tuned to make slight changes to the entire unit.
How long does an LED display last?
Determining the precise life of an LED display is difficult because several factors are involved. However, proper maintenance does the trick for almost everything, LED displays included. With the right maintenance, LED displays can last the past 10 years.
Electronics depreciate over time. This can be attributed to environmental factors such as heat and light. Other environmental factors such as humidity and salt content can also affect its longevity.
Additionally, the daily use of LED displays also affects their longevity. Higher brightness and light images reduce longevity compared to darker and lower brightness levels.
Pixel pitch and display resolution
Pixel pitch refers to the distance to the center of the neighboring diodes. This distance is measured from the center of each group of red, green, and blue diodes.
Resolution refers to the distance between an LED's display diodes. The resolution of a display is normally given as a pair of numbers. The pair indicates the height and width in pixels. On the other hand, the pixel pitch is measured in centimeters (cm). Therefore, if you have a 4x6 meter screen with a 1cm pixel pitch, your resolution is 400x600 pixels.
Advantages of LED technology
The flexibility of application and brighter images
LED screens can be used in outdoor parks, town squares, or shopping spaces. This is because the screens are not washed out by bright surrounding light. Furthermore, excess light which filters through windows and doors does not affect the functionality of LED screens
Improved tech, reduced prices
LED screens are worth your money, especially considering the display's scale. Large spaces like shopping malls require LED screens because of their overall resolution and pixels per inch. Therefore, the display comes at an affordable price while maintaining high quality
The bottom line
The manufacturing of LED screens is a huge step in technological advancements. LED displays are known to be energy efficient and cost-effective, making them adaptable to be used indoors and outdoors
While choosing a resolution, always consider the viewing distance. If the display is at floor level in the middle of a mall, a high-resolution display works efficiently because the audience will get close to it
The longevity of an LED display depends on several external factors, such as humidity, salt air content, heat, and light. It is important to maintain the LED displays carefully.
LED displays are known to be highly energy efficient. The technology is improved, and thus the prices are affordable, especially on a larger-scale LED display
