Engineering Contradiction Analysis
1Adaptability or versatility
If more signal transmission lines are added to handle increased circuit complexity, then signal transmission capability is improved, but layout space consumption increases
Solution Approach 1:
The patent divides the pixel circuit into multiple sub-circuits (first pixel circuit and second pixel circuit), each with its own driving circuit. This segmentation allows independent operation of each sub-circuit, enabling the sharing of common signal lines while maintaining full functionality, thus reducing the total number of signal lines required and optimizing layout space utilization.
2Area of stationary object
If circuit spacing is reduced to increase circuit density, then layout space utilization is improved, but signal interference and circuit complexity increase
Solution Approach 1:
The patent merges the data lines of the first and second pixel circuits into a single common data line. Additionally, scanning lines are shared between adjacent pixel circuits. This merging approach reduces the total number of signal lines, simplifies the circuit structure, and enables tighter spacing between circuits while maintaining signal integrity and reducing interference.
