Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single electric field is applied to the liquid crystal display medium, then the structure is simple, but the light transmission control is insufficient and color shifts occur under high voltages
Solution Approach 1:
The liquid crystal display medium is divided into multiple regions (first portion and second portion), and different electric fields are applied to each region through separate electrode structures. This segmentation enables independent control of light transmission in different areas, allowing for grayscale display and color shift prevention without requiring complex overall restructuring
Solution Approach 2:
Different electric field intensities are applied to different portions of the liquid crystal display medium based on local requirements. The first electric field component applies a first intensity to the first portion, while the second electric field component applies a second intensity to the second portion, enabling localized optimization of light transmission control for each region
2Ease of operation
If high voltage is applied to control light transmission, then the light control capability is improved, but color shifts occur due to varying properties of liquid crystal materials
Solution Approach 1:
The display medium is segmented into multiple regions with different liquid crystal materials or different optical requirements. By applying different electric field intensities to different segments, the patent achieves uniform color output across the display while maintaining high light control capability in each region
Solution Approach 2:
The patent changes the electric field intensity parameter differently across various portions of the liquid crystal display medium. By adjusting the intensity of electric field components applied to different regions, the patent compensates for material property variations and maintains consistent color transmission under high voltage conditions

AI summary
A display device includes a first substrate, a second substrate, a first liquid crystal display medium, and a first electric field applying component. The first electric field applying component is configured to apply a first electric field to a first portion of the first liquid crystal display medium and apply a second electric field to a second portion of the first liquid crystal display medium. The intensity of the first electrical field is operatively different from that of the second electrical field.
