Abstract
A display system according to the present invention includes: a dimming device capable of switchably presenting a light reflecting state or a light transmitting state; and a display device for displaying information by modulating light transmitted through the dimming device and/or light reflected by the dimming device. The dimming device has a plurality of regions each being independently capable of switchably presenting a light reflecting state or a light transmitting state, and, when a plurality of types of information are being displayed on the display device, the dimming device is capable of selectively switching between the light reflecting state or the light transmitting state of each of the plurality of regions in accordance with the types of information being displayed.
Claims28
A display system comprising:
- a dimming device capable of switchably presenting a light reflecting state or a light transmitting state;
- and
- a display device for performing display by modulating incident light;
- wherein
- the dimming device is a dimming device having 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;
- 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;
- the element is hydrogen, and the first material is able to transition between a light reflecting state and a light transmitting state in accordance with a hydrogen concentration;
- the second layer contains a hydrogen storage material;
- and
- the display system operates in a region where respective hydrogen equilibrium pressure-composition isotherms (PTC characteristic curves) of the first layer and the second layer are substantially flat.
A display system comprising:
- a dimming device capable of switchably presenting a light reflecting state or a light transmitting state;
- and
- a display device for performing display by modulating incident light;
- wherein
- the dimming device is a dimming device having 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;
- 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;
- and
- the second material releases or absorbs the specific element in response to light irradiation.
A display system comprising:
- a dimming device capable of switchably presenting a light reflecting state or a light transmitting state;
- and
- a display device for performing display by modulating incident light, wherein,
- the dimming device is a dimming device comprising a dimming layer whose light reflectance changes in response to an external stimulation;
- 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;
- and
- a diameter of the particles is equal to or greater than 350 nm and equal to or less than a thickness of the dimming layer.
