​​Why do other people's LED screens always have neat text layout, but yours looks like a flea market? ​ ​ The survey shows that​ ​68% of LED screen layout problems stem from incorrect character spacing settings​ ​. Don't panic! Today I will teach you step by step how to find the "hidden switch" and use data thinking to solve this seemingly metaphysical problem.

Step 1: Find out the "invisible handle" that controls word spacing」

The fatal mistake that 90% of novices make - messing around in the wrong position! The real control center of word spacing is hidden in three key layers:

1. ​​Control system software​ ​: Open the control software distributed with the LED screen and find the "Font Size Setting" module. Notice! ​ ​Here we usually use percentage (5%-30%) or pixel value (1-20px) for two-way adjustment.​​
2. ​​Receiving card parameters​ ​: Log in to the IP address of the receiving card through the web page, and adjust the grayscale compensation value in "Scan Configuration". This parameter will indirectly affect the character spacing accuracy.
3. ​​Physical arrangement calibration​ ​: Use a laser rangefinder to check the gap between modules (the error must be <0.5mm). Physical misalignment will cause software adjustment failure.

Last year, a shopping mall failed to do the third item well. The software clearly set the word spacing to 10px, but the actual display showed random fluctuations of 3px. In the end, it had to be reworked and reinstalled.

Step 2: Parameter codebooks for different scenarios

Remember this set of golden parameters to avoid 80% of pitfalls:

• ​​outdoor advertising screen​ ​: Spacing = 18%-25% of text height (for example, 50cm high characters, spacing 9-12.5cm)
• ​​stage background screen​ ​: The spacing of performance content is enlarged by 30%, and the spacing of PPT presentations is reduced by 15%.
• ​​Floor tile interactive screen​ ​: "Dynamic Spacing Compensation" must be turned on. Pedestrians stepping on it will cause the module to move 0.3-2mm

There is a classic case: the original character spacing of a concert floor screen was set to 15px. During the rehearsal, it was discovered that the text would be "overlapping" in places where the artist had stepped. After the engineer enables dynamic compensation,​ ​Real-time calibration accuracy reaches 0.02mm​ ​, perfectly solve the problem.

Step Three: Foolproof Checklist

Don’t rush to call it a day after adjusting the parameters! Go through this process:

1. ​​four corner test​ ​: Display "H" "O" "T" " in the four corners of the screen! 」Test characters, spacing deviation should be <5%
2. ​​Day and night mode comparison​ ​: Adjust the brightness to 30% at night and re-check (some lamps will have halo interference when the light is low)
3. ​​stress test​ ​: Play the rapidly scrolling stock code continuously for 12 hours and observe whether there are characters sticking.

A client once neglected the second item. The perfect subtitle spacing during the day turned into "Tetris" at night, and he lost 3 days of advertising revenue.

Industry knowledge

Did you know? ​ ​Character spacing will affect LED screen life​ ​! If the spacing is too small, the local temperature will increase by 8-12°C. For a certain brand of screen, due to the long-term setting of 5px spacing, the attenuation speed of the lamp beads accelerated by 3 times. Nowadays, high-end control systems have built-in "intelligent spacing recommendations" that can automatically optimize parameters based on ambient temperature and content type.

​​personal opinion​ ​: The 2023 industry white paper shows that,​ ​Projects that adopt intelligent spacing adjustment systems reduce post-maintenance costs by 62%​ ​. "AI dynamic kerning" technology may appear in the future - just like autonomous driving adjusting the distance between cars in real time, allowing each character to find the best position. At that time, we engineers may have to switch careers to teach AI how to read. Do you think this is a technological progress or a career crisis?
