Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If liquid crystal response time is shortened, then display speed is improved, but transmittance is reduced
Solution Approach 1:
The first electrode is divided into multiple independent segments (first main portions, girder portion, connection portions) that can generate distributed electric fields. This segmentation allows the voltage to be applied more efficiently across the liquid crystal layer, achieving faster response times without sacrificing transmittance, as each segment contributes to the overall switching action independently.
Solution Approach 2:
The electrode patterns extend in both first and second directions, creating a two-dimensional electrode structure rather than simple parallel plates. The first electrode has portions extending in the first direction with connection portions in the second direction, while the second electrode has main portions, branch portions, and extension portions creating a complex 2D pattern. This dimensional complexity optimizes the electric field distribution to improve both response time and transmittance.
2Illumination intensity
If transmittance is maintained at high level, then brightness is improved, but response time increases
Solution Approach 1:
Different portions of the electrodes have different configurations optimized for their local function. The first main portions and second main portions are essentially parallel to the data line direction for optimal voltage application, while connection portions and branch portions extend in the scan line direction for proper electrical connection. The girder portion and extension portions create additional electric field regions. This local optimization allows high transmittance in the display area while maintaining fast response through strategic electrode placement.
3Speed
If electrode configuration is optimized for response time, then display speed is improved, but transmittance is reduced
Solution Approach 1:
The first electrode and second electrode patterns are designed to work together as an integrated system. The connection portions of the first electrode connect to the branch portions and extension portions of the second electrode, creating a unified electric field network. This merging of electrode functions allows the system to achieve fast response times through coordinated switching while maintaining high transmittance through optimized overall pattern design that minimizes light blocking.

AI summary
A pixel structure includes a switching element, a first electrode, and a second electrode. The first electrode includes two first main portions parallel to an extension direction of the data line, a girder portion coupled between the two first main portions, and two connection portions coupled between the two first main portions. The girder portion and the two connection portions are parallel to an extension direction of the scan line, and the girder portion is disposed between the two connection portions. The second electrode includes a second main portion parallel to the extension direction of the data line, multiple branch portions symmetrically coupled with the second main portion, and two extension portions parallel to the extension direction of the data line. Each of the two extension portions is coupled with two of the multiple branch portions.
