Alas, do bosses have such crazy moments? I bought an LED screen that I spent a lot of money and wanted to change the sentence to a promotional advertisement, but the text setting entrance was not found on the screen, so I was so anxious that I slapped my thighs! Today we broke it apart and broke it and said, "You must be more familiar than your own remote control after reading it!"

1. Where is the text setting hidden? (Pre-tested by the three major entrances)

​​Entrance 1: The mysterious key combination of the remote control​​
Don't underestimate the thing that looks like a remote control of the air conditioner! Press and hold ​ ​【Menu + Confirm key】​​ In 3 seconds, 80% of the screen will pop up the hidden text editing interface.

​​Entrance 2: Computer software console​​
When connecting to the screen with supporting software, focus on the one in the upper right corner ​ ​【A】​​ The font icon, click on it to be the font library’s nest. Remember to save the slogan as a .txt document in advance, and drag it in directly to use it!

​​Entrance 3: Remote control of mobile APP​​
New smart screen scan body QR code installation APP, ​ ​"Content Management - Text Template"​​ If you choose the right style, you can change the advertising slogans on the subway. Last year, the manager of a milk tea shop changed the "second cup half price" when he was squatting in the toilet, and sales rose by 40% that month!

2. Three-piece set of text adjustment (the master's meal guy)

1. ​​Font selection guide​​

• Don’t use Song style if you want to kill the outdoor screen! The strokes are too thin and the sun will get blurred. Recommended ​ ​Bold body/Microsoft black and thick​​
• Neon light effect selection ​​Round font​​ , avoid LED lamp beads exposing jagged edges
• Must-have for multilingual display ​​Siyuan Font Library​​ , Chinese, English, Thai and Chinese

​​Lessons of blood and tears​​: A hot pot restaurant used the word "art" and the word "pot" was shown as "光", and the customer laughed for a whole year...

2. ​​How to set the rolling speed? ​ ​

​​Golden Rules​​: Number of text lines × single line reading time = optimal scrolling period, if it exceeds 7 lines, it will be displayed in a grade

3. ​​Color matching metaphysics​​

• The red background is yellow ​​King Blast Combination​​ , the visible distance outside is increased by 50%
• Blue background white characters suitable ​​Medical venue​​ , looks professional and refreshing
• Use the word "gradual rainbow" with caution! Maybe it looks like a KTV light show

​​Cold knowledge​​: The human eye has the highest sensitivity to green, but the full green background will trigger ​​Visual fatigue​​ , it is recommended to use 30% green as embellishment

3. Essential skills for advanced players (let your peers call them expert)

▎Multilingual mixed ordering is not serialized

Don’t go crazy when you encounter Chinese and English mix! Remember these three steps:

1. Check it in the software ​​【Auto Alignment】​​ Function
2. Arial fonts are used in English, and the font size is 20% larger than that in Chinese
3. insert ​​Invisible separator​​ | Prevent line breaking errors

The bilingual screen I made for the international exhibition last year was to win millions of orders with this trick!

▎Emergency situation handling manual

​​Status 1: Incomplete text display​​
→ Check whether the text box size ≥ screen resolution
→ Change the full-width symbol to half-width
→ Delete the invisible format copied from WeChat

​​Situation 2: Text shaking like a storm​​
→ Refresh rate is set to ≥1920Hz
→ Replace the power cord with more than 2.5 square millimeters
→ The grounding resistance must be <4Ω

​​Situation 3: Special characters change to question mark​​
→ Install the extended font library package
→ Switch the encoding format to UTF-8
→ Disable automatic simplified and traditional Chinese conversion of the system

Ten-year-old technicians are silent (after listening to it, they take less detours for three years)

Some screens now come with their own ​​AI layout​​ Function, can automatically adjust the font size line spacing according to the content. But don't rely entirely on machines! The screen display of poetry made for the art museum last week, AI arranged the seven-character quatrains into a rap rhythm, which made the director so angry that he almost smashed the screen...

Let me tell you about the industry secret: ​​The most stable content modification is 2-5 am​​ ! During this period, the power grid is less interference and signal transmission is not prone to errors. That's how we debug the Olympic venues!

Finally, I would like to remind all the bosses: I must do it after modifying the text. ​​Aging test​​ ! Only by rolling continuously for 48 hours without making any mistakes can you be considered qualified. Don’t wait for the screen to become dumb on the day of the event, it will be even more uncomfortable than throwing your wallet!
