TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a conventional organic EL display structure is used, then the display can be manufactured with standard processes, but the pixel layout area is large and definition is limited
Why choose this principle:
The patent utilizes multi-layer conductive structures (first conductive layer, second conductive layer, third conductive layer) stacked in different dimensions to form capacitance units and pixel circuits. This vertical stacking approach reduces the horizontal pixel layout area while maintaining all necessary circuit functions, thereby achieving high definition displays with compact pixel structures.
Principle concept:
If a conventional organic EL display structure is used, then the display can be manufactured with standard processes, but the pixel layout area is large and definition is limited
Why choose this principle:
The conductive layers serve multiple functions simultaneously: the first and second conductive layers form capacitance units for signal holding, the third conductive layer provides power supply distribution, and combinations of these layers create pixel circuit elements. This multi-functionality reduces the number of separate components needed, shrinking the overall pixel area.
