LIQUID CRYSTAL LENS, DISPLAY DEVICE AND DRIVING METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18032226 titled 'LIQUID CRYSTAL LENS, DISPLAY DEVICE AND DRIVING METHOD THEREFOR
Simplified Explanation
The abstract describes a liquid crystal lens that includes two substrates, a liquid crystal layer with multiple lens units, and electrodes to drive the rotation of liquid crystal molecules and adjust the curvature of the lens units. It also includes a planar layer to smooth the electric field and a light-shielding layer.
- The liquid crystal lens has a first and second substrate.
- It includes a liquid crystal layer with multiple lens units.
- The lens units are driven by an electric field created by a first and second electrode.
- The first electrode has independent sub-electrodes at adjacent positions of adjacent lens units.
- The second electrode is a planar electrode.
- A first planar layer is present to smooth the electric field intensity variation curve.
- A light-shielding layer is located between the substrates.
Potential Applications
- Camera lenses
- Microscopes
- Telescopes
- Virtual reality headsets
- Augmented reality displays
Problems Solved
- Allows for adjustable curvature of the lens units.
- Provides a smooth electric field for improved performance.
- Offers light-shielding to prevent unwanted light transmission.
Benefits
- Improved image quality and focus control.
- Versatile and adaptable lens curvature.
- Enhanced user experience in various optical devices.
- Reduction in unwanted light interference.
Original Abstract Submitted
A liquid crystal lens liquid crystal lens includes: a first substrate and a second substrate; a liquid crystal layer including a plurality of liquid crystal lens units; a first electrode including a plurality of independent sub-electrodes, and there are sub-electrodes at adjacent positions of adjacent liquid crystal lens units; a second electrode being a planar electrode, the first electrode and the second electrode are configured to form an electric field to drive liquid crystal molecules of the liquid crystal layer to rotate, and adjust the curvature of the liquid crystal lens units; a first planar layer located on the side of the first electrode facing the liquid crystal layer, the first planar layer being configured to smooth an intensity variation curve of the electric field of the liquid crystal lens units; and a light-shielding layer located between the first substrate and the second substrate.
