OPTICAL DIMMING DEVICES WITH CHIRAL FERROELECTRIC NEMATIC LIQUID CRYSTAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094584 titled 'OPTICAL DIMMING DEVICES WITH CHIRAL FERROELECTRIC NEMATIC LIQUID CRYSTAL

Simplified Explanation

The optical device described in the abstract is a device that includes a medium with ferroelectric liquid crystals and chiral dopants, located adjacent to a first electrode. It may also have a second electrode separate from the first electrode, and can be used as an optical dimming device to control the amount of light passing through based on a voltage gradient.

• The optical device includes a medium with ferroelectric liquid crystals and chiral dopants.
• The medium is located adjacent to a first electrode.
• The device may have a second electrode distinct and separate from the first electrode.
• It can be used as an optical dimming device to control the amount of light passing through based on a voltage gradient.

Potential Applications

The technology could be used in:

• Smart windows
• Adjustable tint eyeglasses
• Light modulators

Problems Solved

• Inefficient light control
• Limited dimming options
• Lack of flexibility in optical devices

Benefits

• Improved light control
• Enhanced dimming capabilities
