Alas, why are billboards and concert screens all over the streets now replaced by LEDs? Don’t the old-fashioned LCD screens and neon lights taste good? Let’s talk about it today, where is this LED screen awesome! (Catch the thermos and drink a sip of water)

PK in the first round: Who knows better under the sun?

Let's talk about the real thing first——​​The truth is to see clearly outdoors​​! The traditional LCD screen is like a layer of yarn at noon, and the reflection is so severe that it can be seen as a mirror. The LED screen is smart.​ ​Outdoor models directly reach brightness of 4000cd/m²​​, it still looks really good at noon.

For example, a music festival last year used an old-fashioned projection screen, but in the afternoon the audience became "blind" together. I changed my LED screen this year, guess what? Even the back row audience can see the sweat beads on the lead singer's face! This gap is not a small part.

The second round of competition: Who saves more electricity bills?

Let me tell you a heart-wrenching data: a 100㎡ advertising screen in an ordinary shopping mall.​​LED's monthly electricity bill can save more than 20,000 yuan compared to traditional neon lights​​! The secret lies in the LED's luminous principle - they precisely control each small lamp bead, unlike the traditional screen's entire backlighting board that is lit up desperately.

What's even more amazing is​​Intelligent dimming technology​​, automatically fill up the brightness in broad daylight, and dim when there are fewer people in the middle of the night. This is like turning on the energy-saving mode of the air conditioner at home, and the speed of the meter will drop immediately. I know a convenience store owner. After changing to the LED menu screen, the electricity bill was cut by one-third in a year, and he was so happy that he was proud of him when he saw people.

The third round of showdown: How many years can it be used to not be scrapped?

Here is a comparison of hardcore data:

Why are so much different? Traditional screen backlight tubes are like light bulbs, and they will inevitably become dimmed after being used for a long time. Each pixel of the LED emits light independently, and the number of broken lamp beads will not affect the overall situation. Last time I went to the repair shop, I saw an LED station screen that had been used for 7 years. Although the corners were a little dark, the main information was still clearly displayed.

Round 4: Who has more ways to play?

This is the time for LEDs to be successful! Traditional screens are basically square in shape, and LED screens can be played with:

• The whole wall becomes​​Transparent window​​, product and ad overlay display
• The ground is covered​​Interactive floor tiles screen​​, it can produce special effects of flowers when stepped on
• Wrap the column into​​Cylindrical display​​, 360° without blind spots

I saw the shopping mall atrium with my own eyes last year on New Year's Eve​​Wavy LED Dome​​The picture flows ups and downs with the music, and the effect is amazing! If a traditional screen wants to have this shape, it is afraid that the screen will have to be cut into eight pieces.

Ultimate showdown: Can't you lose the chain at critical moments?

Let me tell you the truth - a traditional screen originally used by a certain airport, snowflakes appeared eight times when it rained heavily. After changing the LED,​ ​IP65 waterproof level directly withstands typhoon days​​, the flight information is clear. What's even more amazing is​ ​1920Hz ultra high refresh rate​​, no longer afraid of disgusting scanning lines when shooting videos.

Maintenance master Lao Zhang told me that it is much easier to maintain LED screens now. In the past, when I repaired a traditional screen, I had to replace the entire module. Now, which lamp bead is broken and which one is replaced. The replacement lamp beads that are always available in the toolbox are about the same size as buttons.

If I want to say, this LED screen is like a smartphone replacing the big brother. It is not a simple technological upgrade, but a revolution in the entire display method. Now even rural theaters have started to use LED background screens. Think about this trend! But then again, if you only watch a TV at home, a traditional LCD screen is enough. But when it comes to commercial displays and large-scale events, it still has to be the LED screen carrying the banner.

I heard recently that some manufacturers are doing it​​Flexible LED reel screen​​, it looks like a scroll when put away. Maybe in two years, we can really take the display screen rolling Basketball bag away! Technology is really becoming more and more magical... (I took a look at the time) I'll end up talking about it today. Next time I have time, I'll talk about some inside information about the industry!
