Abstract
Various displays may benefit from suitable lenses. For example, certain vehicle displays may benefit from a curved, segmented, active-dimmable lens. According to certain embodiments, a system may include a segmented indium-tin-oxide layer. The system may also include a rigid lens disposed over the segmented indium-tin-oxide layer. The rigid lens may be curved.
Claims20
A display system comprising:
- a control circuit;
- a display in communication with the control circuit operable to generate an optical signal;
- and
- an active dimmable lens cooperating with the display to receive the optical signal from the display and vary a transmission of the optical signal through the lens, wherein the active dimmable lens includes:
- a curved cover layer having a first surface and an opposing second surface,
- an active cell disposed adjacent the second surface of the cover layer operable to vary the optical signal transmitted from the display through the active cell in response to a signal from the control circuit, wherein the active cell includes:
- an indium-tin-oxide (ITO) common plane layer disposed on the second surface of the cover layer,
- one or more segmented ITO layers adjacent the ITO common plane layer,
- a dye-doped liquid crystal disposed between the ITO common plane layer and the one or more segmented ITO layers, and
- an encapsulation layer, wherein the encapsulation layer cooperates with the ITO common plane layer to retain the dye-doped liquid crystal and one or more ITO segmented layers, and
- a linear polarizer operable to polarize the optical signal disposed adjacent the encapsulation layer of the active cell and positioned between the encapsulation layer and the display.
