Abstract
Provided are a light control film whereby flickering is hard to recognize when observing external light via the light control film, a light control member comprising same, a vehicle, and an electricity supply method for the light control film. In the vehicle 130, the light control film 1 having a vertically-aligned liquid crystal layer is attached to a sunroof 132. The light control film 1 is attached to the sunroof 132 of the vehicle 130 such that the liquid crystal molecules fall to the rear of the vehicle 130 when an electric field is applied to the liquid crystal layer. As a result, passengers in the vehicle do not sense any flickering inside the car and have no discomfort.
Claims15
A vehicle comprising:
- a sunroof;
- and
- a light control film having a vertically-aligned liquid crystal layer attached to the sunroof,
- wherein the light control film is attached to the sunroof of the vehicle such that liquid crystal molecules fall to a rear of the vehicle when an electric field is applied to the liquid crystal layer.
A light control film, comprising:
- a planar transparent electrode which is arranged on a base material and provided with an electricity supply point connected to a driving power source;
- and
- an electrical wire electrically connected to the transparent electrode, wherein
- the electricity supply point is provided in an outer edge portion of the transparent electrode, and
- the electrical wire extends along the outer edge portion of the base material from the electricity supply point and is electrically connected to the transparent electrode at a connection point provided at a position different from the electricity supply point.
A method for supplying electricity to a light control film including a planar transparent electrode for which an electricity supply point connected to a driving power source is provided and an electrical wire electrically connected to the transparent electrode, the method comprising:
- supplying electricity to the transparent electrode from the electricity supply point and a connection point provided in a position different from the electricity supply point, both of which are provided in an outer edge portion of the transparent electrode.
