Just bought an LED display, but I couldn't find the text setting button and was sweating in a hurry? Don’t panic! It's like a newly bought smartphone, the function keys are hidden deep but finding the right method is simple. Let’s talk about this today - after all, even Uncle Zhang, who runs a supermarket next door, can get started for three days, so you must be fine! I heard that many newbies are searching for "LED screen text setting tutorial" recently, and it seems that this is indeed a necessity.

The first step is to find your command center"

All LED screens have a core component called​​Control card​​, it is equivalent to the operating system of a mobile phone. There are two mainstream ways to play now:

1. ​​Local operation​​: Use matching physical buttons or remote control (suitable for small screens)
2. ​​Remote control​​: Through computer software/mobile phone APP (recommended to large-screen users)

For example, three-story advertising screens like those in shopping malls must be controlled by computers to facilitate. Here is a tip: first find out the model of your screen. Usually, the cover of the manual contains codes such as NS-P4 and NS-Q6. Remember to find the corresponding software.

The three secrets for text arrangement in the second step

​​Scene 1: Static text display​​

• Font size recommendation: every 1 meter increase in viewing distance, font size is enlarged by 10cm
• Color scheme: The most eye-catching white characters on red background (contrast ≥500:1)
• Special effects selection: Use the flashing effect with caution! It is easy to cause photosensitive epilepsy

​​Scene 2: Scroll subtitles settings​​

• Scrolling speed = screen width ÷ residence time (for example, if a 3-meter-wide screen wants to keep text for 5 seconds, the speed is set to 0.6 meters/second)
• The line break spacing should not be less than 1/3 of the height of the word
• Say important things three times: Remember to test the visibility of different perspectives!

​​Scene 3: Smart content switching​​

• Time segment display: breakfast shops promote soy milk set meals in the morning and buy lunch boxes at noon
• Weather linkage: umbrella promotion information will automatically pop up on rainy days
• Human flu: When the camera detects a gathering crowd, switch the activity preview immediately

High-frequency problem self-diagnosis room

​​Q: Why is the text always blurry? ​ ​
→ Check three places:

1. Does the physical resolution of the screen match the content size (don't cast the mobile wallpaper directly to the 8K screen)
2. Is the grayscale level ≥16bit (below this one, there will be color blocks)
3. Have the refresh rate been adjusted to above 1920Hz (this parameter determines the stability of the screen)

​​Q: The text set suddenly garbled? ​ ​
→ Three-step first aid:

1. Check if the heat dissipation port of the control card is blocked (overheating will cause a crash)
2. Confirm that the power supply voltage is stable at 220V±5% (voltage fluctuations are the enemy)
3. Alternative solution: Save USB flash drive backup files in advance, which can save lives at critical moments

​​Q: How to display different content in different areas? ​ ​
→ Two solutions:

• Partition controller solution (suitable for fixed area division)
• Point-by-point addressing technology (can play with any shape combination)

The golden rule of parameter setting

Here is a comparison table to help you make quick decisions:

Pay attention to the brightness unit is cd/m². The larger the number, the less you are afraid of sunlight. But don't blindly chase highs - too high brightness will not only cost electricity, but will also cause light pollution to be complained about.

The guide to avoid pits: Five common mistakes that novices make

1. ​​Map the computer resolution directly to the LED screen​​
   → Correct way: Use the adaptive zoom function of the control software

2. ​​Save text content in JPG format​​
   → Lessons from blood and tears: The edge jagged makes you cry! Be sure to save PNG transparent bottom map

3. ​​Ignore pixel spacing parameters​​
   → Formula: Minimum viewing distance (meters) = pixel spacing (mm) × 2
   For example, the viewing distance of P6 screen should not be less than 12 meters

4. ​​24 hours full brightness operation​​
   → Intelligent adjustment is the king: 100% brightness at 8 am, and 10 pm will automatically reduce 30%

5. ​​Forgot to set up security protection​​
   → Three things you must do:

   • Set the operation password
   • Turn on abnormal power outage protection
   • Regularly backup configuration files

​​Editor's opinion time:​​
Setting up text is like adding salt to stir-frying dishes - at the beginning, I can't get the quantity accurately, and I'll try it a few more times and find the feel. Three key points should be identified:​ ​Don't check the equipment parameters, test the display effect frequently, and don't be lazy in maintenance.​​. I have seen too many people spend a lot of money to buy good screens, but because of improper settings, I really feel like I'm so frustrated! It is recommended that novices find a reliable manufacturer, which one can provide full-process technical support, and one-stop service from installation to debug can save worry. Remember, good screens are re-loaded, not just pretend!
