Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IPS mode LCDs use transverse electric field to increase viewing angle to 170°, then viewing angle is improved, but transmissivity and contrast ratio deteriorate
Solution Approach 1:
The invention divides the single electrode layer into two separate electrode layers (first electrode layer on first substrate, second electrode layer on second substrate). Each layer contains slit electrodes that generate electric fields, creating a combined multi-dimensional electric field configuration that improves both viewing angle and transmissivity
Solution Approach 2:
The invention transitions from a two-dimensional electric field (single layer) to a three-dimensional multi-dimensional electric field by adding depth through separate electrode layers on both substrates. This spatial dimensionality enhancement allows simultaneous achievement of wide viewing angle and high transmissivity
2Illumination intensity
If ADS mode LCDs form multi-dimensional electric field with slit electrodes, then transmissivity and viewing angle are improved, but driving voltage increases
Solution Approach 1:
The invention segments the electric field generation into two independent electrode layers, allowing each layer to contribute partially to the total electric field. This distribution reduces the voltage burden on each individual layer while maintaining the multi-dimensional field effect for high transmissivity
Solution Approach 2:
The invention combines the electric field effects from two separate electrode layers to achieve the desired multi-dimensional field configuration. The synergistic combination of both layers produces the required field strength with reduced individual layer voltage requirements
3Illumination intensity
If stronger transverse E-field is applied to increase transmissivity, then transmissivity is improved, but driving voltage increases
Solution Approach 1:
The invention creates a multi-dimensional electric field configuration with electrode layers on both substrates, allowing the electric field to act on liquid crystal molecules from multiple spatial directions. This dimensional enhancement achieves high transmissivity with reduced voltage by utilizing spatial field distribution rather than relying solely on increased field strength
