All plain black screen Issue on Display Running LVGL

Hi Everyone,

All plain black screen appears on my display after initializing LVGL. The setup includes an STM32F429 microcontroller with an ILI9341 display driver, and Iam using LVGL version 8.3.
The screen remains blank, and no UI elements are rendered, though the backlight is functioning.

I have double-checked my display driver setup and ensured LVGL is initialized correctly, but the issue persists.

Has anyone faced a full black black screen problem? Any tips on debugging this or identifying if it’s a driver or LVGL configuration issue? please gave me suggestion , Thank you.
