What Is LED Screen Brightness?


1. Introduction


Brightness is an attribute of visual perception. It affects how we appreciate and see things in our environment. In most cases, we or some people see brightness as an elementary factor for devices. It is often an indescribable parameter that we can only say sufficient or not when we already see it regardless of the number or level.

And when we talk about screens and displays in the technological and digital field, brightness is a decisive factor. It affects all other color functions such as contrast, gamma, and more when it is not enough or too high. That’s why it is essential to set it rightfully to keep the LED screen’s tremendous and just brightness level. 

Meanwhile, this article will discuss how to resolve your devices’ brightness problems. 


2. What Is Brightness?


Brightness is one of the most important aspects of a screen and digital device. It is a parameter on phones, tablets, TVs, computers, and LED screens. 

Brightness is an indescribable thing, but here’s a scenario. Have you ever sat down outside and decided to turn on your phone to watch some videos or chat with friends? Then while scrolling down, you find it hard to read, comment, or see photos because of the insufficient light from the screen. It would be best if you turned up the brightness to keep things more visible to your eyes.

However, the brightness factor of your device can be different such as an outdoor LED screen has higher brightness than indoor ones. We’ll tackle it later.

Brightness is how the eyes perceive the luminance of a visual target. It is measured in a lumen or symbols goes as lm. Like typical numbers, the higher the lumen, the high brightness, and a low number means lower brightness capacity. In the LED display field, we measure LED screen brightness in nits or cd/m².

Brightness is a very particular factor you have to check upon LED screen purchase. Somehow, this factor signals whether a device is more reliable and functional. But, on a side note, it is not the only parameter you have to check. There are materials, sizes, and designs that an LED screen is comprised of.


3. LED Screen Brightness And LCD Screen Brightness


Brightness and brightness capacity varies from one device to another. That means your television can have a higher brightness level than your tablet or phone. It is not typically based on the device’s size but mostly depends on its usage, viewer size, etc.

Brightness Comparison

Commonly, we hear comparisons between LED and LCD when it comes to brightness. It is unjust to say LCD is better than LED or LED is better than LCD. Both devices have features, advantages, and disadvantages, but if we are to compare them in brightness alone, the LED screen wins the game. An LED screen such as LED TV has individual dimming and backlight, making the screen look more refined, authentic, and realistic to natural images.

Also, LED screens have a higher brightness capacity than LCD devices. Why? It is because LED screens are more frequently applied to outdoor applications. We know how bright the outdoor environment is, so the LED screen brightness should be higher to make it visible in the daytime. Also, the high bright LED screen makes a better view, a more accurate content display, and more visually appealing and catchy.


4. What Triggers Brightness Problem And How To Resolve It?


 Undeniably, once in a while, devices also exhibit troubles. These problems can have various roots and reasons, such as poor maintenance, a natural cause, or by accident. 

And when it comes to brightness troubles, LED screens are no new to the list. Brightness problems have a variety of causes, and you can quickly solve some of these problems. Here are a few reasons why brightness often deteriorates on your devices.

  • Poor Maintenance

Most likely, brightness encounter problems when the device is not properly maintained. It happens when the brightness is left too high when turning off the device or not adjusted from time to time. Defective diodes can also affect the screen’s brightness, so it’s essential to perform either front or rear maintenance.

Now, what’s the best thing to do to avoid it?

  1. Check the device’s brightness from time to time. Make sure there are no defective diodes on the module or whole screen. If there’s any, make sure to contact your provider right away.
  2. Adjust brightness according to the environmental requirements. It should not be too high or too low.
  3. Do not leave the brightness too high when you turn off the device. This method works best on televisions and tablets and is also effective on LED screens. Before turning off the machine, ensure the brightness is set to low. It is to avoid disturbance on the internal processing of the device once turned on.
  • Accident/ Natural Cause

Some natural disasters happen without us having any clue. LED screens, especially those installed outdoors, are often bound to experience these natural disasters.

As an LED screen owner, how will you respond to such problems? Here are tips.

  1. LED screens often encounter accidents, especially those installed near highways and streets. And often, these happenings leave the device broken or, if still working, then deteriorate its performance. In this case, contacting your provider for help and consultation is best.
  2. LED screens that are somehow damaged due to disaster can still be used. However, to ensure that it is not defective and working still, check its function, brightness level, and other parameters.

  • Product Lifespan

LED screens last for years. Some stay for decades, depending on how frequently it was used and maintained.

Often, brightness is the first factor that signals the ending lifespan of an LED screen. You’ll see the device dimming, or its maximum brightness is too low than its typical highest brightness level. When this happens, it is best to contact your provider to know whether it needs replacement.


5. Good LED Screen Brightness And Product Quality


High brightness LED screen often signals that the device is reliable and cost-effective. However, it is not efficient to say that brightness alone makes a dependable device. There are still other factors that affect the reliability of a device, such as an LED screen. 

When LED screens are designed, the brightness is also customized. If you apply the screen outdoors, the device typically comes in a higher brightness than LEDs. Outdoor LED displays have a higher brightness requirement to match the environment, especially during the daytime.

When LED screens are manufactured, when do we check the brightness? Brightness setting and inspections happen during the display test. It is a type of test LED screens go through after the aging test. In the display test, our skilled team and experts check the parameters and intangible properties of the LED screen.

It primarily includes the brightness, refresh rate, contrast ratio, gamma, and other color specifications. In this process, we also check if there are any defective diodes and software installations.
