Having the ideal brightness and colors of the LED screen is vital. Without this, your LED display screen will not function properly. And to make matters worse, the luminance and colors can get abnormal. So you will need to correct these from time to time.
LED screen calibration is the technique that helps us here. In this post, I will discuss this technique and how it functions. So, let’s get started.
What does it mean by LED screen calibration?
The process ensures that all LED modules’ color and brightness are consistent. Due to this consistency, a uniformly high-quality image appears. In addition, all the colors are at a stable temperature. As a result, a white-balanced color shows up.
It is a necessity for every display screen. Without it, the display will be of low quality. It will appear distorted. Thus, calibration is critical. In addition, it is vital to provide an appealing visual experience to viewers.
Almost all of us have LED displays at our homes, offices, or schools. Some of you may have noted that the colors appear dull on the screen after some time. There is no precision in the colors. You might think that your display screen has completed its age. Don’t worry. Try calibrating your LED screen first.
It is a time-saving and cost-effective process. And it will probably help you bring color consistency to your display screen. It is a simple process. It will save you from the screen’s unbalanced light and color pattern.
How can you test the image calibration of your LED display?
Even if you have calibrated it, your screen may not have the exact brightness or color. Due to this, it is crucial to test the calibration of your display screen. Then, if you have any problems with colors or brightness, you will be able to fix them.
But how will you test the calibration? Don’t you worry? I will describe a simple way to do it in steps:
- You need to open the image viewing program that supports color management.
- After this, access to a grayscale gradient of a large size.
- A poorly calibrated screen will have jumps in tone, and bands of color appear on it.
- If you see this, it indicates that you will need to calibrate the screen.
- It is best to test the calibration monthly to ensure everything is smooth.
Why does the LED screen have issues of consistency of color and brightness?
We have discussed that the screen may lack the consistency of colors and brightness. But what are the reasons behind this? Why does it happen? Here, I have written some of these reasons:
- The difference in production time
- Different LED display module production cycles
- The mask color of the LED module
- LED module driver IC
- Flatness between the LED modules
- Flatness before the LED screen cabinet
- Aging of the LED display screen
Due to problems relating to these, we can have a poorly calibrated screen.
What is the brightness calibration of an LED display?
If all the LEDs are at a matched brightness, the display screen will have a calibrated brightness. It means that for calibration, you should match every LED’s brightness. Then, you can turn the brightness down until they are all matched.
Let me explain this process to you by an example. For instance, one section of the display screen has a brightness of 1200 nits. But, simultaneously, the other section of the display screen has a brightness of 1100 nits. Thus, you will need to lower the 1200 nits to 1100 nits. In this way, the brightness will be identical and calibrated.
It also shows one more thing. The weakest LED of the screen becomes the maximum calibrated brightness.
Initially, when the display screens are new, they may have a 10-20% variance in brightness. But you don’t need to fix it. Instead, as the manufacturer, we would calibrate the screen for you for the first time. Unfortunately, the variance also increases when your display screen gets old. It is probably due to heat production.
Indoor screens work on low brightness. It reduces LED depreciation. As a result, it extends the age of the display screen. Rotating the display panels can also help develop the screen’s life.
How to calibrate your LED display?
Here, we will discuss how you can perform the led screen calibration. People use both Windows and Mac. Both of these have different procedures of calibration.
First, let us discuss calibration if you are using Windows:
- You will need to find and open the desktop settings.
- Once you have accessed it, you should go to advanced display settings.
- After this, click on the color calibration.
- Adjust the brightness and color balance.
- Also, optimize the gamma settings and contrast.
- After this, click on the finish option.
Second, if you use the Mac, you need to follow this process:
- You see the apple icon on the top of your screen.
- Please open it and select the system preference option.
- After this, you will go to the display and then color.
- As a result, an option of calibrating will appear. And then go to screen calibration assistant.
- With the help of the assistant, optimize the white point. You will adjust it based on the example displayed on the screen.
- Then, name your color profile. And click on the finish option.
Besides, you can also invest in a colorimeter. It is a device that measures the absorbance of wavelengths. So the colorimeter provides the ideal color profile. And we can have a well-calibrated and well-balanced screen.
This device examines the colors on the display screen. It automatically optimizes the color and brightness of the display. This device helps us to calibrate the screen more precisely.
What are the benefits of calibrating an LED display?
There are many benefits of adequately calibrating the display screen. It is a fact. It ensures that you enjoy the best visual experience. Besides, some of the other benefits of calibration are as follows:
- LED screen calibration ensures the quality of the image. It allows us to have a more consistent image quality. It is critical if the colors of the image are essential for your work.
- If the backlights work standard, the lifespan of the display screen increases. For this, the backlights should operate at balanced and correct levels. It can only happen if you have calibrated the display screen. When the screen colors are accurate and balanced, the backlights function correctly. Thus, LED screen calibration also increases the lifespan of the screen.
- By calibrating the screen, the screen’s brightness will be average. It further reduces the usage of power.
- When the colors and brightness are correct, the image quality on the screen is also high. You get to experience high-quality visuals.
- The pictures will be more accurate and have more detail and resolution.
Conclusion:
I hope that after reading this, you can get some idea of how important it is. Why should you calibrate your led screen? An unbalanced brightness and colors can trouble you.
Thus, I recommend you calibrate your display screens regularly. In this way, your LED display works fine.
