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 it 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.
Brightness is a decisive factor in screens and displays in the technological and digital fields. Insufficient or too high luminance affects all other color functions, such as contrast, gamma, etc. That’s why it is essential to set it right to maintain the LED screen’s tremendous brightness level.
Meanwhile, this article will discuss resolving your devices’ brightness problems.
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 indescribable, but here’s a scenario: Have you ever sat outside and turned on your phone to watch 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 to turn up the luminance to keep things more visible to your eyes.
However, your device’s luminance factor can be different, such as a higher brightness outdoor LED screen than an indoor one. We’ll tackle this later.
Brightness is how the eyes perceive the luminance of a visual target. It is measured in lumens or symbols, such as lm. Like typical numbers, the higher the lumen, the higher the luminance; a low number means lower brightness capacity. In the LED display field, we measure LED screen luminance in nits or cd/m².
Brightness is a particular factor you must check upon purchasing an LED screen. Somehow, this factor signals whether a device is more reliable and functional. But, on a side note, it is not the only parameter you must check. There are materials, sizes, and designs that an LED screen is comprised of.
LED Screen Brightness And LCD Screen Brightness
Brightness and luminance capacity vary from one device to another. That means your television can be more bright than your tablet or phone. It is not typically based on the device’s size but mostly depends on its usage, viewer size, etc.
We commonly hear comparisons between LED and LCD when it comes to luminance. 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 compare them in luminance alone, the LED screen wins the game. A bright LED screen, such as an 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 luminance capacity than LCD devices. Why? LED screens are more frequently used in outdoor applications. We know how bright the outdoor environment is, so the brightness of the LED screen should be higher to make it visible in the daytime. Also, a high-brightness LED screen provides a better view, a more accurate content display, and a more visually appealing and catchy display.
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 an accident.
Regarding brightness troubles, LED screen brightness is not a new addition 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
Brightness problems most likely occur when the device is not properly maintained. This happens when the brightness is left too high when the device is turned off or not adjusted periodically. 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?
- Check the device’s brightness periodically. Ensure there are no defective diodes on the module or the whole screen. If there are any, contact your provider right away.
- Adjust brightness according to the environmental requirements. It should not be too high or too low.
- Do not leave the brightness too high when you turn off the device. This method works best on televisions and tablets and is effective on LED screens. Before turning off the machine, ensure the brightness is low to avoid disturbing the device’s internal processing once it is turned on.
Accident/Natural Cause
Some natural disasters happen without our knowledge. High brightness LED screen, especially those installed outdoors, are often bound to experience these natural disasters.
As a high bright LED screen owner, how will you respond to such problems? Here are tips.
- LED screens often encounter accidents, especially those installed near highways and streets. These accidents usually leave the device broken or, if still working, deteriorate its performance. In this case, it is best to contact your provider for help and consultation.
- LED screens damaged by a disaster can still be used. However, check their function, luminance level, and other parameters to ensure they are not defective and still working.
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 end of the lifespan of a high brightness LED display screen. You’ll see the device dimming or its maximum brightness being too low compared to its typical highest brightness level. When this happens, it is best to contact your provider to determine whether it needs replacement.
Good LED Screen Brightness And Product Quality
High brightness LED screen often signals that the device is reliable and cost-effective. However, it is inefficient to say that luminance 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 the screen is applied outdoors, the device typically has a higher luminance than LEDs. Outdoor LED displays have a higher luminance requirement to match the environment, especially during the daytime.
When LED screens are manufactured, when do we check their luminance? Brightness settings and inspections are performed during the display test, a type of test LED screens undergo after the ageing test. In the display test, our skilled team and experts check the parameters and intangible properties of the LED screen.
It primarily includes luminance, refresh rate, contrast ratio, gamma, and other color specifications. In this process, we also check for defective diodes and software installations.
