Engineering Contradiction Analysis
1Manufacturing precision
If a liquid crystal lens is formed using conventional electrode patterns with uniform voltage application, then the device structure is simple, but the three-dimensional image quality deteriorates due to distortion on vertical and horizontal views
Solution Approach 1:
The electrode pattern is segmented into multiple regions: a first electrode with a first pattern, a second electrode with a second pattern, and a third electrode with a third pattern. Each electrode applies a different voltage to the liquid crystal layer, enabling precise control of the liquid crystal orientation to reduce distortion and improve three-dimensional image quality without excessive overall complexity.
Solution Approach 2:
Different voltage levels are applied to different regions of the liquid crystal layer through the segmented electrode patterns. The first electrode applies a first voltage, the second electrode applies a second voltage, and the third electrode applies a third voltage, creating local variations in liquid crystal orientation that correct distortion in specific viewing areas while maintaining overall image quality.
2Manufacturing precision
If different voltages are applied to control liquid crystal orientation for high-quality 3D images, then the image quality improves, but the control system complexity increases
Solution Approach 1:
The voltage control system is segmented into three independent voltage sources, each connected to a specific electrode pattern. This segmentation allows precise control of liquid crystal orientation in different regions while keeping each control circuit relatively simple, avoiding the need for a single complex control system.
Solution Approach 2:
Instead of applying a single voltage to control the entire liquid crystal layer, the invention applies multiple different voltages simultaneously to different regions. This inverted approach of using voltage differentiation rather than uniform voltage enables precise local control of liquid crystal orientation, improving three-dimensional image quality while distributing control complexity across multiple simple voltage sources.

AI summary
A liquid crystal display device is configured to form a three dimensional image on the vertical view by applying a first voltage between a narrow electrode on the first substrate and a wide electrode on the second substrate, and a second voltage lower than the first voltage between the wide electrode on the first substrate and the wide electrode on the second substrate, and to form a three dimensional image on the horizontal view by applying the first voltage between the wide electrode on the first substrate and a narrow electrode on the second substrate, and the second voltage between the wide electrode on the first substrate and the wide electrode on the second substrate so as to reduce generation of domain in the horizontal electric field.
