August 07, 2024

We have written many articles about LED display in our Blog to help you better understand about it. Some of you may be new to LED display, so we have specially written "What is LED display and what are the parameters we need to know before choosing an LED display? "We hope it can help you understand more about LED display.

So what exactly is an LED display? Think of it as a giant screen made up of many little lights called LEDs. These LEDs can display text, pictures, and video content. They consume less power, have a long life, are bright, and you can see them from a great angle or a great distance.

Each little light or LED is like a building block. When you put them together, they form the screen. the LEDs are like little light bulbs that show you the image you see.

Types of LED Displays

Over the years, LED displays have become commonplace. From Micro Led Display to DOOH LED Display Screen, they are everywhere. Whether it's a High Integration All in One LED TV for your living room or a Sport Stadium Perimeter LED Display, LED displays have something for every need.

What Goes Into an LED Display?

The Screen: This is the part with all the LEDs.

Mounting Stuff: Keeps the screen steady and in place.

Brains of the Operation: Controls what shows up on the screen.

Data Pipeline: Sends info from the brains to the screen.

Multimedia Wizardry: Handles the sound and video.

Power Hub: Makes sure the screen gets its juice.

Status Check: Monitors how the screen is doing.

Cooling System: Keeps everything from overheating.

Important Words and Stuff

1. Pixels

Think of pixels as the smallest dots on a screen. Each pixel is made up of the colors red, green, and blue. These colors are mixed together to form the colors you see.

2. Brightness

If you're outside in the sun, you need a brighter screen so you can see clearly. Indoors, on the other hand, you don't need a high brightness because of the low light in the room. Here's a quick guide:

Direct Sun (Facing North): Super bright, over 8,000 nits.

Direct Sun (Facing South): Still bright, 5,000 to 8,000 nits.

Indirect Sun: 3,000 to 5,000 nits.

Shaded Outdoor: 1,000 to 3,000 nits.

Indoor with Sun: 1,000 to 2,000 nits.

Bright Indoor: 500 to 1,000 nits.

Dim Indoor: 300 to 500 nits.

3. Viewing Angle

The viewing angle is how well you can see the screen from the sides. If you can see it clearly from the side, it has a good viewing angle. For indoor screens, you want something around 140 degrees. For outdoor screens, 100 degrees is good enough.

4. Gray Scale Levels

This is how many shades of gray the screen can show. More shades mean more detail and better colors. Most screens have 256 shades or more, which is plenty for most people.

5. Refresh Rate

The refresh rate is how often the screen updates the picture. The faster it updates, the smoother the picture looks. For most screens, you want at least 100 times per second (100Hz).

6. Pixel Failure Rate

This is the percentage of pixels that aren’t working right. There are standards for how many bad pixels are okay. For outdoor screens, it’s less than 0.2%. For indoor screens, it’s less than 0.03%.

7. Screen Lifespan

How long the screen lasts depends on a few things, but mostly on how long the LEDs last. LEDs usually keep going until they’re only half as bright as when they were new.

How to Take Care of Your Screen

To maintain stable operation of the LED display, follow the tips below:

Keep It Dry: Make sure the area isn’t too humid, or the screen could rust.

Be Gentle: Keep sharp objects away from the screen and clean it softly.

Regular Cleaning: Dust it off regularly so it stays clear.

Steady Power: Use a good power source and make sure it’s grounded.

No Water: Don’t let water get inside the screen.

Switch On and Off Right: Turn the screen on after you power it up and turn it off before you shut it down.

Don’t Go Full White: Avoid turning on the screen with a full white screen to prevent too much current.

Manage Heat: Don’t run the screen in super hot conditions or without good air flow.

Daily Break: Give the screen a rest for at least two hours a day.

Cleaning Tips: Use alcohol, a soft brush, or a vacuum cleaner to clean. Some screens shouldn’t be cleaned with water.

Check Regularly: Look over the screen every once in a while to make sure everything’s working and fix anything that’s broken.

Picking an Indoor Led Display

When you’re looking for an indoor LED display, think about:

Viewing Position: Choose an LED display based on your location; for example, if you choose a P1.25 display, you'll get better brightness and color without noticeable graininess from 1.5 meters away.

That’s the lowdown on LED displays! With this knowledge, you should be able to choose the right display for whatever you need.
