Is there a big but slow e-ink display?

Question

Iron

Colleagues, such a question.
Maybe someone can point me in the right direction for information. Are there E-ink displays somewhere in nature that refresh slowly, but have a large physical size? Let at least an hour for one update, but the size is from a meter to a meter.
So far, the largest that I have found is 13.5 inches , but it is not enough and a little expensive. Maybe there is something on some other technology. In principle, a prototype is enough for me to test the idea, it is not at all necessary that it be the final product.
Thanks in advance for your replies and have a great day everyone!
