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.
Claims14
A mask plate, comprising:
- a first transparent substrate;
- first transparent electrode, an electrochromic layer and a second transparent electrode arranged sequentially on the first transparent substrate;
- and
- thin film transistor (TFT) array arranged between the first transparent substrate and the first transparent electrode and configured to selectively supply power to the first transparent electrode,
- herein the first transparent electrode is configured to be selectively powered to form energized regions with different shapes,
- the first transparent electrode is of a grid-like structure consisting of horizontal electrode lines and longitudinal electrode lines crossing each other.
A method for manufacturing a mask plate, comprising:
- providing a first transparent substrate;
- providing a thin film transistor (TFT) array on the first transparent substrate;
- providing a first transparent electrode on the TFT array;
- forming an electrochromic layer on the first transparent electrode;
- and
- providing a second transparent electrode on the electrochromic layer,
- wherein the first transparent electrode is selectively powered by the TFT array to form energized regions with different shapes,
- the first transparent electrode is of a grid-like structure consisting of horizontal electrode lines and longitudinal electrode lines crossing each other and each electrode line is connected to a drain electrode of a TFT unit of the TFT array adjacent to the electrode line.
