A photoelectric modulation stack comprises a substrate, multiple touch sensing units, at least one first anti-interference patch and a nano-structure layer, wherein the touch sensing units are arranged on the substrate in a coplanar manner, and a first gap zone is formed between every two adjacent touch sensing units; each first anti-interference patch is arranged in the corresponding first gap zone, and the width of each first anti-interference patch is much smaller than that of the substrate or each touch sensing unit; the nano-structure layer is arranged below each first anti-interference patch and has multiple nano-structures. When light rays pass through the nano-structures and the at least one first anti-interference patch, the optical characteristics of the light rays are changed.
