LVGL on monochrome display

I have a monochrome display with 1bpp fbuffer (without grayscales) , is it possible to run LVGL in truly 1bpp mode without exxessive memory usage for 1 bit per color RGB?

Hi, I think if it’s a monochrome display it might be related to oled and I also saw some oled projects with lvgl, they seem viable, should you take a look at them

edit: may epaper work same like , see epaper
