1. Advantages of COB LED display screens in display effects
COB LED display screens perform very well in contrast and colour reproduction. It is like a well-designed “small black room” that hides the LED chip inside.
It is difficult for outside light to come in and interfere with it, so the black looks purer, the light and dark contrast of the picture is stronger, and the details are clearer.
Moreover, the chips used in this display screen are of good quality and can present rich colours, whether bright red, bright yellow or deep blue.
They can be restored very realistically, just like the natural scenery you see with your own eyes, and the colours will not be distorted.
Le angle de vue of the COB LED display screen is particularly wide, almost reaching more than 160°.
This means that no matter where you stand, you can see a clear, consistent colour picture.
Unlike some screens, the colour will not be distorted or dimmed if it is slightly off.
For example, in the stadium of a large des sports event, no matter where the audience sits, they can clearly see the game picture and will not miss the wonderful moments.
Moreover, the surface of this display is very flat, and the spacing between pixels is very small, so the picture looks very delicate and has no obvious graininess.
Even if you look very closely, it is difficult to see the existence of pixels. Just like watching HDTV, the picture is smooth and natural, and it looks comfortable.
The structure of the COB LED display is very solid, like a sturdy “small house”, which can well resist external shocks and vibrations.
The circuit connection inside is also very stable, and it is not easy to have problems such as cold soldering and short circuits.
This means that in the long-term use process, it rarely fails and can always present high-quality pictures stably.
It does not need to be repaired or replaced frequently, which saves worry and effort. Moreover, it is also highly resistant to external electromagnetic interference in some complex electromagnetic environments.
For example, in industrial control centres or large shopping malls, it can normally work without flickering or jumping off the screen due to interference from electromagnetic signals.
The brightness distribution of the COB LED display is very uniform because its packaging method can keep the electrical connection and heat dissipation conditions of each LED chip consistent.
This means that the luminosité of the entire screen is very uniform, and there will be no bright spots or dark spots, and the picture looks more coordinated and beautiful.
For example, on large billboards, no matter from which angle you look at it, the brightness of the picture is the same, which can attract the audience’s attention very well.
In addition, this display has a high refresh rate, which can quickly update the picture content and reduce smear and blur.
Displaying high-speed moving pictures, such as sports events or e-sports, can clearly capture every detail of the action, allowing the audience to see smooth and clear pictures and enhance the viewing experience.
2. Why is the display effect of COB LED display clearer?
1). No graininess
Imagine that you are looking at a painting. If the paint dots of the painting are dense, the picture will look very delicate.
COB LED display is like this: it integrates many small lamp beads (LED chips) tightly together, just like painting dots of paint evenly on a canvas.
Moreover, its surface is very flat, without small particles protruding like other screens.
So, when you look closely, you won’t see those dots one by one; the picture is like a smooth painting; it looks very clear, without that kind of “graininess”.
2). High contrast
Have you ever tried to look at the screen of your mobile phone in the sun, and the black part of the screen looks a little grey, and the details are not clear? COB LED display will not be like this.
It is like a “small black room”, blocking all the light outside, and the black inside looks particularly pure.
In this way, the light and dark contrast of the picture is particularly obvious, just like looking at a layered photo. Every detail can be seen clearly, and the picture is naturally clearer.
3). Large angle de vue
Imagine you are watching a large concert, and the screen on the stage is very large; if you sit in the corner, will the picture on the screen look distorted, or the colour is wrong? COB LED display will not be like this.
Its viewing angle is particularly wide, and no matter where you sit, you can see a clear and colour-consistent picture.
It’s like watching a great show. No matter where you sit, you can clearly see every action on the stage, and the picture looks very clear without distortion due to angle problems.
4). High fréquence de rafraîchissement
Have you ever tried to watch a fast-moving picture, such as a car race, and the picture is a little blurry, and you can’t see the details clearly?
The refresh rate of the COB LED display is very high, just like a super fast camera that can quickly capture every moment.
So, even if there are fast-moving objects in the picture, there will be no blur or ghosting.It’s like watching a high-speed car race.
Every turn and every acceleration can be seen clearly, and the picture looks very clear, so you won’t miss any wonderful moments.
5). Good brightness uniformity
Imagine you are reading a book with poor printing; some places are very light, and some places are very thick, which makes it look uncomfortable.
The brightness of the COB LED display is very uniform, just like a beautifully printed book, and the brightness of each page is the same.
In this way, the picture looks very coordinated, and the visual effect will not be affected by uneven brightness.
Moreover, this uniform brightness distribution can also make you watch for a long time without feeling eye fatigue, and the picture looks very clear and comfortable.
6). Strong anti-interference ability
Imagine that you are listening to music in a noisy environment, and it is easy to be disturbed by the surrounding noise.
The COB LED display is like a headset with a super shielding function, which can shield the electromagnetic interference from the outside world.
Therefore, even in complex environments, such as shopping malls or factories, it can work stably without flickering or jumping.
It is like in a noisy environment, the display can still work stably, and there will be no picture problems due to external interference, so the audience can watch with peace of mind, and the picture looks very clear.
3. Compared with other LED displays, how is the display effect of COB LED display?
1). Rich color performance
The COB LED display can present very rich colours. It uses high-quality LED chips, which can emit very pure light in the three basic colours of red, green and blue.
By precisely controlling the intensity of these three colours of light, COB LED displays can mix almost any colour with very high colour saturation and accuracy.
This means that whether it is showing bright flowers, a blue sky or a deep ocean, the picture can present a very realistic colour effect.
In contrast, some other types of LED displays may be slightly inferior in colour richness and accuracy, resulting in the picture not looking vivid enough.
2). High brightness and no glare
COB LED displays can provide very high brightness, and the picture can still be clearly seen even in bright environments, such as direct sunlight outdoors or strong light indoors.
This is very important for some scenes that need to be used under various lighting conditions, such as outdoor advertising screens, stage background screens, etc.
At the same time, the brightness adjustment function of the COB LED display is also very good.
It can automatically adjust the brightness according to different ambient light, which can ensure the clarity of the picture without being dazzling due to excessive brightness.
This intelligent brightness adjustment function not only improves the viewing experience but also reduces eye fatigue.
3). Low consommation d'énergie
COB LED display screens have low power consumption while providing high-quality display effects.
This is because COB packaging technology can use electrical energy more efficiently and reduce energy loss.
Low power consumption not only means lower operating costs but also means more environmental protection for some display screens that need to run for a long time.
For example, 24-hour store advertising screens or information display screens in large public places make the advantage of low power consumption even more obvious.
It can help users save a lot of electricity bills and also reduce the impact on the environment.
4). Long life
COB LED display screens have a long service life. Due to the robustness of its packaging structure and good heat dissipation performance, LED chips can work in a stable environment, reducing damage caused by overheating or other environmental factors.
This means that COB LED display screens can maintain stable display effects during long-term use without problems such as brightness reduction and colour deviation.
In contrast, some other types of LED display screens may experience a decline in display effects after a period of use due to poor heat dissipation or other packaging problems.
Long-life display screens not only reduce replacement costs but also ensure the continuous stability of display effects.
4. In which application is the COB LED display screen suitable for use?
1). Large stades
