Engineering Contradiction Analysis
1Measurement precision
If multiple pixel electrodes are coupled with data lines and scan lines to provide data signals according to image information, then display resolution is improved, but parasitic capacitances increase causing pixel-to-pixel crosstalk and voltage sharing
Solution Approach 1:
The pixel structure is divided into multiple independent conductive layers (first conducting layer, second conducting layer, third conducting layer) that are stacked vertically. Each layer serves a specific function: the first conducting layer is coupled to the active switch, the second conducting layer is coupled to the common line, and the third conducting layer forms the L-shaped conductive wire. This segmentation isolates the parasitic capacitances into separate layers, preventing them from causing horizontal crosstalk between adjacent pixels while maintaining high display resolution.
2Reliability
If the pixel structure uses traditional single-layer capacitor design, then device complexity is reduced, but voltage retention is insufficient leading to abnormal coloration
Solution Approach 1:
The invention transitions from a traditional single-layer capacitor design to a multi-layer stacked capacitor structure. The first conducting layer, second conducting layer, and third conducting layer are stacked vertically in the third dimension, with insulating layers between them. This vertical stacking provides multiple capacitance paths for voltage retention without increasing the horizontal footprint of the pixel, thereby improving voltage stability and preventing abnormal coloration while maintaining compact device complexity.
