== Notes and version constraints ==
* The source contains no explicit warnings; the following points require human confirmation:
* The FPC and glass panel of the large screen are fragile – handle with care when developing; reinforce the FPC with tape if needed.
* Connect all cables before powering on; hot-plugging is not supported.
* In low-temperature environments, color deviation may occur; recommended to stabilize at 25 °C for 6 hours.
* Screens without a backlight continue displaying the last content after power failure; avoid direct sunlight.
* Recommended update interval: at least every 24 hours to prevent burn-in.
* Prolonged high-voltage operation can burn out the screen; switch to sleep mode or power off after each refresh.
* After deep sleep mode, the screen must be re-initialized via software.
