2. Last time it worked normally, there was no data on the LED screen after power on (VS-C)

It may be due to the button battery on the card running out of power. Just replace it with a new button battery (only VS-C may have this situation).
3. Why is the word displayed in the special effects not the entire word?

Text can be divided into multiple lines with adjustable line spacing, which is used for publishing a large amount of information. Subtitles and text can be input in different font sizes and sizes.
Can Arabic and Vietnamese be displayed?
Using text can display all text and special characters from around the world (provided that it can be displayed on your computer itself).
7. The display screen shakes when running characters
Please reduce the “entry speed” and “exit speed” of the program appropriately.
8. Why does the control card appear with a few seconds of bright lines or “splash screen” when it is first powered on?
After connecting the display controller to the computer and display screen properly, it is necessary to provide+5V power to the controller to ensure its normal operation (at this time, do not directly connect to 220V voltage). At the moment of power on, there will be a few seconds of bright lines or “splash screen” on the display screen, which is a normal test phenomenon, reminding the user that the display screen is about to start working normally. Within 2 seconds, this phenomenon will automatically disappear and the display screen will enter normal working state.
