A display device is provided, including a first flexible substrate, a second flexible substrate, an electrode layer, and a TFT circuit. The second flexible substrate is disposed opposite to the first flexible substrate. The electrode layer is formed on the first flexible substrate. The TFT circuit is formed on the first flexible substrate. The first flexible substrate has a first light transmission chromaticity coordinates (x1, y1), the second flexible substrate has a second light transmission chromaticity coordinates (x2, y2), and x1−x2≥0.002 or y1−y2≥0.002.

A light attenuator that provides transparent light states and absorbing dark states for use in selectively controlling light, especially for smart glass applications. The light attenuator includes abutting areas of attenuation and transparency that form a repeat pattern or a quasi-repeat pattern. The attenuating areas are visible when the light attenuator is in the light state, but the repeat pattern is sufficiently large that a viewer looks through the attenuator and sees no haze.

An optical element which can be utilized in various versions and implementations of switchable light filters having, in addition, polarization filters and/or other means for varying the polarization characteristics of light, for example, liquid crystal layers. A combination of switchable light filter and imaging display device makes possible a private viewing effect that can be switched on and off. The optical element comprises a first layer or a first layer and a plurality of further layers, each layer including a material with a plurality of light-absorbing transition dipole moments. At least in a first state, each transition dipole moment is oriented, with a tolerance of 10° at the maximum, parallel to a selectable preferential direction or fluctuates around it so that light which is incident in the optical element is transmitted or at least partially absorbed depending on its incident direction.

A display system includes: a transmissive liquid crystal display panel; a light control panel having an active area with a light control area; a temperature detector provided in the liquid crystal display panel and having a detection area with a resistive element; a backlight; and a controller. A display area of the liquid crystal display panel, the active area, and the detection area overlap on an optical path of a projection light. The light control panel is disposed at such an angle that, when the light control area is in a light reflection state, the light control panel reflects external light to a position out of the optical path and different from a position of the liquid crystal display panel. The controller causes the light control area to reflect light when an output indicating that the resistive element has a predetermined temperature or higher is obtained.

A trim element having a first aspect layer, a lighting device emitting light to the first aspect layer, and a first obturation layer extending between the lighting device and the first aspect layer. The first obturation layer includes at least two first optical obturation areas, configurable between an open position, in which a first optical obturation area lets light pass through, and a closed position, in which a first optical obturation area prevents the passage of light. The trim element includes a second aspect layer and a second obturation layer having at least two second optical obturation areas that are configurable between an open position and a closed position.

According to one embodiment, a light control device comprises a first liquid crystal cell includes a first liquid crystal layer, a second liquid crystal cell includes a second liquid crystal layer, and a third liquid crystal cell includes a third liquid crystal layer. The first liquid crystal layer and the third liquid crystal layer each have a first region that scatters a first polarization component and that transmits a second polarization component. The second liquid crystal layer has a third region that overlaps the first region and converts the second polarization component into the first polarization component.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

An apparatus can include an electrochromic device configured to be maintained a continuously graded transmission state. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded transmission state and maintained in the continuously graded transmission state. The current during switching can be higher than current during maintaining the continuously graded transmission state. In an embodiment, the grading can be reversed to provide a mirror image of the grading. In another embodiment, at least 27% and up to 100% of the electrochromic device can be in a continuously graded transmission state. The control device can be located within an insulating glass unit, adjacent to the insulating glass unit, or remotely from the insulating glass unit. In a further embodiment, a gap between bus bars can be used to form a portion of the electrochromic device that can be continuously graded.

A system such as a vehicle may have adjustable structures such as adjustable windows. Adjustable windows may have adjustable layers such as adjustable tint layers, adjustable reflectivity layers, and adjustable haze layers. Adjustable window layers may be incorporated into a window with one or more transparent structural layers such as a pair of glass window layers. Adjustable components such as adjustable reflectivity layers, adjustable haze layers, and adjustable tint layers may be interposed between the pair of glass window layers. Fixed partially reflective mirrors, fixed tint layers, and/or fixed haze layers may be used in place of adjustable tint, haze, and reflectivity layers and/or may be incorporated into windows in addition to adjustable tint, haze, and reflectivity layers.

A light transmitting panel assembly includes a first panel, a second panel, a frame, a gap between the first panel and the second panel, and a first active component located between the first panel and the second panel.
