Engineering Contradiction Analysis
1Reliability
If multiple light-emitting elements are arranged in an array without a common gate electrode, then each element can be controlled independently, but the elements cannot be switched ON/OFF in synchronization
Solution Approach 1:
Multiple gate electrodes are merged into a single common gate electrode that extends beneath multiple light-emitting elements. This allows all elements to be controlled simultaneously by a single control signal, achieving synchronized ON/OFF operation while reducing the number of control electrodes needed.
Solution Approach 2:
The common gate electrode serves multiple functions: it acts as a control electrode for multiple light-emitting elements simultaneously, and also functions as a reference potential electrode for the entire array. This multi-functionality simplifies the overall device structure while maintaining synchronization capability.
2Productivity
If light-emitting elements are operated without synchronized control, then the electrode structure is simpler, but power saving and light extraction efficiency are reduced
Solution Approach 1:
The common gate electrode combines multiple control functions into a single structure, enabling synchronized operation that improves light extraction efficiency and power saving performance without requiring separate control electrodes for each light-emitting element.
