Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single emission signal is used to control light emitting elements, then the device structure is simple, but the viewing angle cannot be dynamically adjusted according to different modes
Solution Approach 1:
The gate driving circuit is segmented into multiple mode controllers (first mode controller, second mode controller) that can independently control different emission signals. Each mode controller is responsible for specific viewing angle modes, allowing the circuit to provide different emission patterns without requiring a complete redesign of the entire system.
Solution Approach 2:
The gate driving circuit is designed with multi-functional mode controllers that can operate in different modes (first mode, second mode) to provide various emission signals. The same circuit structure can adapt to different viewing angle requirements by switching between modes, making the circuit universally applicable for multiple display scenarios.
2Adaptability or versatility
If multiple emission signals are used to control different viewing angles, then the viewing angle can be dynamically adjusted, but the circuit complexity increases
Solution Approach 1:
Multiple mode controllers are merged into a single gate driving circuit system that shares common components such as voltage lines, signal lines, and control logic. The first mode controller and second mode controller are integrated within the same circuit framework, reducing the overall complexity compared to having completely separate control systems.
Solution Approach 2:
The circuit employs dynamic mode switching capability where the gate driving circuit can transition between different operating modes (first mode, second mode) based on display requirements. This dynamic adaptability allows the system to adjust emission characteristics without requiring multiple static circuit configurations.
3Adaptability or versatility
If the gate driving circuit is designed for high adaptability with multiple modes, then viewing conditions can be optimized, but the manufacturing complexity increases
Solution Approach 1:
Different regions of the gate driving circuit are designed with specific local characteristics optimized for their functions. The first mode controller and second mode controller have differentiated local structures that handle specific emission control tasks, while sharing common infrastructure. This local quality approach allows specialized functionality without requiring complete circuit redesign.
Solution Approach 2:
The circuit design incorporates preliminary configuration of mode controllers and their associated transistors and capacitors during the manufacturing process. The gate driving circuit is pre-configured with the necessary components for multiple modes, enabling flexible operation after manufacturing without requiring additional assembly steps or post-processing.
