Abstract
A dimming device is provided by using a material which is capable of transitioning between a metallic reflection state and a transmitting state. The dimming device has a layered structure including a first layer and a second layer, such that the light reflectance of the first layer changes in response to an external stimulation. The first layer contains a first material whose optical characteristics change in accordance with a concentration of a specific element. The second layer contains a second material capable of containing the specific element, the second material releasing or absorbing the specific element in accordance with the external stimulation.
Claims44
A dimming device comprising a layered structure including a first layer and a second layer, such that a light reflectance of the first layer changes in response to an external stimulation, wherein,
- the first layer contains a first material whose optical characteristics change in accordance with a concentration of a specific element, and
- the second layer contains a second material capable of containing the specific element, the second material releasing or absorbing the specific element in accordance with the external stimulation.
A dimming device comprising a dimming layer whose light reflectance changes in response to an external stimulation, wherein,
- the dimming layer contains a first material whose optical characteristics change in accordance with a concentration of a specific element, the first material being particles.
A dimming device comprising a dimming layer whose light reflectance changes in response to an external stimulation, wherein the dimming layer
- contains a first material whose optical characteristics change in accordance with a concentration of a specific element, and
- contains a second material capable of containing the specific element, the second material releasing or absorbing the specific element in accordance with the external stimulation, wherein
- the first material is particles.
A display device including a plurality of pixels, each of the plurality of pixels having:
- a first layer containing a first material whose optical characteristics change in accordance with a concentration of a specific element;
- a second layer containing a second material capable of containing the specific element, the second material releasing or absorbing the specific element upon application of a voltage;
- and
- a pair of electrodes for applying the voltage to the second layer,
- wherein a light reflectance of the first layer changes in response to the voltage.
