Abstract
This disclosure describes a dimming panel and its driving method, a preparation method and a controlling device, and a controlling system. The dimming panel includes a substrate, a first transparent electrode layer and an insulating layer sequentially disposed on the substrate, and a curled structure disposed on the insulating layer. The curled structure includes a second transparent electrode layer that has a preset inherent force for curling. The second flexible electrode layer is configured to absorb or reflect light. The first transparent electrode layer and the insulating layer have groove structures that are formed corresponding to each other. The curled structure can be disposed within the groove structure.
Claims19
A system, comprising:
- a dimming panel, comprising:
- a substrate;
- a first transparent electrode layer disposed on the substrate;
- an insulating layer disposed on the first transparent electrode layer, the first transparent electrode layer and the insulating layer having corresponding structures with respect to one another that define a groove structure;
- and
- a curled structure connected to the groove structure, wherein:
- the curled structure in a curled state is at least partially located within the groove structure;
- the curled structure has a preset inherent stress for curling to absorb or reflect light in an unfolded state;
- the curled structure comprises a second flexible electrode layer;
- and
- a depth of the groove structure is greater than or equal to a curling height of the curled structure in a curled state.
A preparation method of a dimming panel, comprising:
- providing a substrate;
- forming a first transparent electrode layer and an insulating layer on the substrate in sequence and the first transparent electrode layer and the insulating layer each having a groove structure that is formed corresponding to each other;
- and
- providing a curled structure in the groove structure, wherein:
- the curled structure in the curled state is at least partially located within the groove structure;
- the curled structure has the preset inherent stress of curling for absorbing or reflecting light in the unfolded state;
- the curled structure comprises a second flexible electrode layer;
- and
- a depth of the groove structure is greater than or equal to a curling height of the curled structure in a curled state.
