Abstract
In one example, a liquid crystal (LC) assembly includes a first curved glass layer and a second curved glass layer. The LC assembly further includes a film-based, flexible LC stack structure between the first curved glass layer and the second curved glass layer. The film-based, flexible LC stack structure includes Guest-Host (GH) liquid crystals. The film-based, flexible LC stack structure is configured to provide both a display operation for displaying content to one or more user and a dimming operation for reducing a transmittance level of light passing through the LC assembly.
Claims12
A liquid crystal (LC) assembly comprising:
- a first curved glass layer;
- a second curved glass layer;
- and
- a film-based, flexible LC stack structure between the first curved glass layer and the second curved glass layer, the film-based, flexible LC stack structure comprising Guest-Host (GH) liquid crystals,
- wherein the film-based, flexible LC stack structure is configured to provide both a display operation for displaying content to one or more user and a dimming operation for reducing a transmittance level of light passing through the LC assembly,
- wherein the film-based, flexible LC stack structure comprises a plurality of controllable segments, wherein a dimming state of each of the plurality of controllable segments is individually controllable, and
- wherein the plurality of controllable segments comprises:
- a background segment configured to provide the dimming operation;
- and
- a plurality of pixel segments configured to provide the display operation by operating a first subset of the plurality of pixel segments in a different dimming state than the background segment.
A liquid crystal (LC) assembly comprising:
- a first curved glass layer;
- a second curved glass layer;
- and a film-based, flexible LC stack structure between the first curved glass layer and the second curved glass layer, the film-based, flexible LC stack structure comprising twisted nematic (TN) liquid crystals, wherein the film-based, flexible LC stack structure is configured to provide both a display operation for displaying content to one or more user and a dimming operation for reducing a transmittance level of light passing through the LC assembly,
- wherein the film-based, flexible LC stack structure comprises a plurality of controllable segments, wherein a dimming state of each controllable segment is individually controllable, and
- wherein the plurality of controllable segments comprises:
- a background segment configured to provide the dimming operation;
- and
- a plurality of pixel segments configured to provide the display operation by operating a first subset of the plurality of pixel segments in a different dimming state than the background segment.
