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.
