The bin’s format is raw true color.

lv_img_set_src(ui->Home_Background_img, "F:bg.bin");

Hi, it is possible that your display’s flush function is not working correctly. Have you ever been able to display an image correctly in the past?

Can you post your (display model)_flush() function, found in your drivers folder? The file containing this function should be named something like (displaymodel).c, where displaymodel is the model number of the physical display you are using.

Also, provide some more info, are you using an RTOS? How are you initializing LVGL? can you post your gui_task() function from your main.c or whatever function that you are initializing LVGL from?

I’ve been a little busy lately,forget to end this topic.
This problem has been soloved.
The source of this problem is the wrong bin file.This bin file was dameged when i transfer it to flash.
