Abstract
A mask plate is provided. The mask plate includes a first transparent substrate. A first transparent electrode, an electrochromic layer and a second transparent electrode are arranged sequentially on the first transparent substrate. The first transparent electrode is configured to be selectively powered so as to form energized regions with different shapes. A method for manufacturing the mask plate, a device including the mask plate, and a method for using the mask plate are further provided.
