How does the refresh rate affect the visual effects of LED displays?
What is the best refresh rate for an led screen
Do you know how to increase the refresh rate?
What driver IC should we use to get a high refresh rate led screen?
The refresh rate is one of the important data in the شاشة عرض LED specification sheet; why do people pay so much attention to the refresh rate? What does this have to do with the LED display?
1. What is the معدل التحديث?
Regarding the refresh rate of LED displays, you may be curious about what this refresh rate is. In fact, the refresh rate is a very important technical indicator, which is used to measure the number of times the image is redrawn on the LED display per second.
The refresh rate directly affects our visual experience when watching the display. When we look at the LED display, the clear, stable, and colorful image on the screen is not static.
In fact, it is formed by each LED lamp bead being continuously updated and refreshed hundreds or even thousands of times in a very short period of time. This update speed is so fast that the human eye cannot perceive each individual change, so the image we see appears smooth and flicker-free.
1). So, how to measure this refresh speed?
This requires the unit of refresh rate, namely nuclear magnetic, which has a clear definition in the international measurement system. In daily use, for the sake of simplicity, we often abbreviate nuclear magnetic field as “Hz”.
So, when we say that the refresh rate of a certain LED display is XX Hz, it means that the display can redraw the image XX times per second, thus bringing us a more realistic and delicate visual enjoyment.
2. What is the impact of refresh rate on the visual effect of LED display?
The refresh rate has a vital impact on the visual effect of LED displays. If your LED screen specification clearly states that the refresh rate is 1920Hz, it means that the image of this display can be refreshed 1920 times in one second.
When the refresh rate is higher than this value, such as reaching or exceeding 1920Hz, we usually call it a high refresh rate, and this refresh rate level is enough for most LED display scenes.
The refresh rate directly determines the number of images that the LED display can play per second. The higher the refresh rate, the more images the display can present per second, and the better the smoothness and stability of the picture.
1). So, what is the difference between a high refresh rate and a low refresh rate in the actual application?
If the refresh rate is too low, the human eye may experience screen jitter when watching the LED display screen, which not only affects the viewing experience but also makes people feel uncomfortable.
At the same time, when shooting a low refresh rate display screen with a video camera or camera, scan lines are likely to appear on the screen, affecting the shooting effect.
Generally speaking, the human eye requires a refresh rate of at least 300Hz so that the picture of the LED display screen will not show obvious jitter.
If you shoot with a camera, depending on the settings and performance of different cameras, a refresh rate of at least 600Hz is generally required to ensure that there are no scan lines in the picture.
In contrast, a high refresh rate LED display screen can significantly improve the سطوع and color fidelity of the picture. When we use a digital camera to shoot a high refresh rate display screen, we will find that the picture taken is very clear, without snowflakes and scan lines, and the color reproduction is also higher.
This indicator is widely used in rental screens and TVs because high refresh rate displays can provide a better viewing experience and shooting effects.
If a low refresh rate LED display screen is used, many problems may be encountered in actual applications.
For example, when shooting with a mobile phone or camera, the picture may flicker repeatedly, or even black bars may appear, resulting in inconsistent picture quality.
Such problems not only fail to capture the real scene and display it but also seriously affect the effect of activities or advertisements. Therefore, when choosing an LED display, the refresh rate is a very important consideration.
A high refresh rate display will undoubtedly bring us a better visual experience and shooting effect.
3. What is the best refresh rate for the led screen?
The best refresh rate for an LED screen is not a fixed number, but depends on how you use the screen. Let’s talk about high and low refresh rates, and why 1920-3840Hz is a suitable range.
- Advantages and disadvantages of high refresh rate
The first advantage is that it is comfortable to watch. With a high refresh rate, such as 3840Hz, the picture moves very smoothly, just like watching the real thing, and the eyes are not tired at all.
Especially when watching fast-moving things or playing games with very fast picture changes, a high refresh rate is simply a magic weapon.
Also, if you plan to use a camera to shoot the screen, a high refresh rate is also essential. Otherwise, the photos or videos you take may have annoying things like water ripples and scan lines, which look unprofessional.
But high refresh rates also have disadvantages. First of all, it consumes electricity. If the screen keeps refreshing at such a high frequency, it will definitely consume a lot of electricity.
In addition, the life of the screen may be affected. After all, what if you are tired after working so “hard” all the time?
- The problem of low refresh rate
On the other hand, low refresh rate is a bit of a headache. The picture may shake and flicker, which is uncomfortable to watch. Especially when playing fast-motion or high-speed changing pictures, it is like watching a slide show.
Let alone using a camera to shoot a screen with a low refresh rate. Scan lines and water ripples are flying all over the sky, and the photos or videos taken are completely unusable.
1). So, what is the appropriate refresh rate?
- Generally speaking, the range of 1920-3840Hz is quite good.
If you are using it indoors, such as in a conference room, exhibition hall, etc., a refresh rate of about 1920Hz is enough. Mainly for watching videos, pictures, and taking photos, there is no need to pursue too high a refresh rate.
But if you are using it outdoors, or have particularly high requirements for picture quality, you have to choose a refresh rate of 3840Hz or higher. The outdoor light is strong, and a high refresh rate can make the picture brighter and clearer.
The same is true for high-quality display. A high refresh rate can make the picture more delicate and smoother.
Of course, if you often need to take pictures of the screen with a camera, a high refresh rate is also essential. Otherwise, the photos or videos taken will not look professional, right?
So, the refresh rate of the LED screen depends on how you use it. Don’t blindly pursue a high refresh rate, and don’t choose a too low refresh rate to save money. In the range of 1920-3840Hz, find a refresh rate that suits you, so that the screen is both beautiful and easy to use!
4. Does the refresh rate make a difference in screen size?
When we talk about the refresh rate of LED displays, it actually has no direct “size relationship” with the size of the screen, just like a person’s height has no direct relationship with his running speed.
Refresh rate, in simple terms, is how many times the screen can refresh per second to make the picture look smoother and more stable, and the unit is Hertz (Hz).
The size of the screen is how long its diagonal is, which determines how far we are best to watch it from.
Now, let’s talk about the impact of refresh rate on LED displays, whether the screen is large or small.
High refresh rates, such as 3840Hz, are like adding an “accelerator” to the picture.
Whether watching fast-moving things or playing games with super fast picture changes, high refresh rates can make the picture move very smoothly, just like watching the real thing and if you use a camera to shoot LED displays, high refresh rates can also help you avoid those annoying water ripples and scan lines, making the photos or videos look more professional.
What about low refresh rates? It’s like watching a movie that is a little bit stuck. The screen may shake or flicker, especially when playing fast-motion or high-speed-changing pictures; you may feel a little tired in your eyes as if you are watching a series of slides.
Moreover, if you use a camera to shoot a low refresh rate LED display, the photos or videos may not be watchable, all of which are scan lines and water ripples.
Speaking of screen size, in fact, whether it is a small screen or a large screen, the refresh rate will bring the above-mentioned effects.
However, when actually using it, we may find that the requirements for refresh rates of large and small screens seem to be a little different.
For example, a small-screen LED display, such as a small indoor display screen, has a short viewing distance, so we have higher requirements for the fineness and smoothness of the picture.
At this time, choosing a screen with a high refresh rate can make the eyes look more comfortable.
For large-screen LED displays, such as outdoor billboards or displays at large events, the viewing distance is far, and our requirements for the fineness of the picture may not be so high.
However, if it is an important event or you need to play high-quality videos, it makes sense to choose a screen with a high refresh rate. After all, no one wants to see a stuck or blurred screen.
Of course, choosing a screen with a high refresh rate is not just a matter of choosing one.
Because high refresh rates usually require more powerful hardware to support, such as graphics cards and processors. Therefore, when choosing a screen, we have to see if our device can support a high refresh rate screen.
In general, the refresh rate is a very important indicator for LED displays, regardless of the size of the screen. When choosing a screen, we have to choose according to our actual needs.
Don’t blindly follow the trend, and don’t choose an inappropriate one just to save money. After all, your eyes are your own, and the most important thing is to look comfortable!
5. Do you know how to increase the refresh rate?
Increasing the refresh rate of the LED display is actually like giving our eyes an “upgrade and transformation” to make everything smoother and more comfortable. So how to do it? Don’t worry, I’ll give you a few tips.
1). Change to a high-end driver IC and turn on the high refresh mode
Do you know that there is a little thing called driver IC in the LED display? It is like a “running coach” that determines the speed of the screen refresh. If you want to increase the refresh rate, you have to find a high-end “coach” to let it “run” faster with the screen.
Moreover, you have to turn on the high refresh mode, which is like adding a “turbocharger” to the screen, and the refresh rate will soar.
2). Choose a powerful display control system software
The software aspect cannot be ignored either, and you have to choose a powerful display control system. For example, Novastar and Brompton are like the “brain” of the screen, processing data quickly and with smart algorithms.
With them, data can be transmitted to the screen quickly, and the refresh rate will naturally be high. Moreover, these software also allow you to adjust the refresh rate at will, as you want.
3). PCB design also requires effort
Don’t forget PCB design, it is like the “blood vessels” of the screen, responsible for transmitting data.
If it is well designed, data can flow smoothly, and the refresh rate will be stable. How to design it? You can put more driver ICs, just like hiring more “running coaches” to make the screen “run” faster.
You can also increase the data buffer processing capacity, just like adding a “boost pump” to the “blood vessels” so that the data can be transmitted faster and more stably.
4). Grayscale parameters must also be considered
Finally, we have to talk about grayscale parameters. It is like the “color palette” of the screen, which determines whether the picture is delicate and the color is good. However, if the refresh rate is too high, the LED may get “tired” faster.
Therefore, you have to choose a high-quality LED display, which is like a “strong” athlete who can withstand the “torture” of high refresh and use it longer.
In general, it is not difficult to increase the refresh rate of the LED display. As long as we work hard on the driver IC, display control system software, PCB design and grayscale parameters, we can make the screen “brand new”.
Of course, when choosing a screen, you have to open your eyes and choose a high-quality one. In this way, our eyes can enjoy a smoother and more comfortable visual feast!
6. What driver IC should be used to get a high refresh rate screen?
When choosing an LED display driver IC that supports a high refresh rate (such as 3840Hz), we have to talk in depth about several key points: refresh rate, grayscale brightness, and those small details that can make the display effect even better.
Now, let me tell you in detail about the actual situation of several driver ICs, and my recommendations.
1). ICN2153, MBI5252
- معدل التحديث:
Hey, the refresh rate of these driver ICs is really not covered; 3840hz is a piece of cake for them. Use them to drive LED displays, and things look smooth, like silk sliding across the skin, which is a great pleasure for the eyes.
- Grayscale brightness:
However, when the refresh rate is high, sometimes the grayscale brightness will be affected. Think about it, if the color of the picture changes, or the display is uneven, it will look so awkward. Just like when you are watching a movie, suddenly the color of the picture is wrong, do you feel that it is very out of the play?
- Other performance:
Of course, these driver ICs have other performance, such as power consumption, stability and so on. But whether it is good or not depends on the specific needs, after all, different scenarios have different requirements for driver ICs.
2). MBI5153
- معدل التحديث:
The refresh rate of MBI5153 is also high, ensuring that your eyes will not feel tired when you look at things, and even fast-moving pictures can be easily captured.
- Grayscale performance:
Speaking of grayscale performance, this is a highlight of MBI5153! When adjusting the brightness, the grayscale will not change at all, and the color is still so bright and real.
Just like when you look at a painting, no matter how the light changes, the color of the painting is still so accurate and natural.
- استقرار:
MBI5153 also uses PWM technology, which is like installing a “cruise control” for the LED display. In this way, the display effect is stable, and there will be no flickering or unstable picture.
- استهلاك الطاقة:
Moreover, MBI5153 is quite power-saving. You know, electricity bills are not cheap now, so it’s better to save a little. Use it to drive LED display screens, and you don’t have to worry about rising electricity bills.
3). MBI5124
- معدل التحديث:
MBI5124 has a high refresh rate, and fast-moving images will not be blurred. Just like when you watch a car race, the car is speeding by, and you can clearly see every detail of the car.
- Grayscale performance:
MBI5124 uses PrecisionDrive™ technology, data transmission is extremely fast, and grayscale performance is super accurate. The colors look natural and the transitions are smooth, just like watching a high-definition movie, every picture is so perfect.
Other functions: MBI5124 also has a constant current drive function, which makes the LED brightness more consistent and more stable. The low-voltage startup function is also very practical, power-saving, and convenient.
There is also a blanking circuit function, which can eliminate ghosting in the picture, making the picture clearer and more realistic.
- Stability and compatibility:
MBI5124’s performance is also very stable and adaptable to various environments. Whether it is indoors or outdoors, high temperature or low temperature, it can work normally. Moreover, it can be matched with other brands of LED display screens and control systems, and it is very convenient to use.
Taking all factors into consideration, I think MBI5153 and MBI5124 are really good choices. They have high refresh rates, good grayscale performance, and the colors look very comfortable and real.
Moreover, they have stable performance and low power consumption, which saves worry and money.
If you want to buy an LED display screen and pursue high refresh rates and good grayscale performance, then MBI5153 and MBI5124 are definitely worth your consideration.
Of course, when choosing a display screen, you must also choose a good quality one so that the entire display system can be more stable and durable. Don’t buy a poor-quality display screen just to save a little money.
Otherwise, it will be more troublesome than it is worth! I hope these suggestions can help you and let you choose the LED display screen you like!
