Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an 8T2C driving circuit is used, then pixel driving requirements are met, but the circuit becomes complex and costly
Solution Approach 1:
The patent extracts and removes unnecessary transistors and capacitors from the traditional 8T2C driving circuit structure, retaining only the essential components needed for pixel driving. This simplification reduces circuit complexity while preserving the core driving functionality, directly resolving the contradiction between meeting pixel driving requirements and reducing circuit complexity.
Solution Approach 2:
The patent applies local quality by optimizing specific portions of the driving circuit rather than redesigning the entire system. By selectively simplifying certain circuit blocks while maintaining critical functions, the patent achieves reduced complexity without compromising overall pixel driving capability.
2Reliability
If an 8T2C driving circuit is used, then pixel driving requirements are met, but manufacturing costs increase
Solution Approach 1:
By extracting and removing redundant transistors and capacitors from the 8T2C structure, the patent reduces the total component count that needs to be manufactured and assembled. This directly lowers manufacturing costs while maintaining the essential pixel driving functionality through the simplified circuit design.
Solution Approach 2:
The patent employs simpler, more cost-effective circuit components and structures that can be manufactured more economically. By replacing complex, expensive components with simpler alternatives that achieve the same functional outcome, the patent reduces manufacturing costs while maintaining pixel driving capability.
3Device complexity
If a simplified driving circuit is used, then costs are reduced and narrow frame is achieved, but circuit functionality must be maintained
Solution Approach 1:
The patent carefully extracts only the non-essential components from the traditional circuit, preserving the core functional elements needed for reliable pixel driving. This selective removal approach ensures that circuit simplification does not compromise driving capability, as the essential functionality is maintained through the retained components.
Solution Approach 2:
The patent employs parameter changes by adjusting circuit configuration, signal timing, or operational parameters to compensate for the reduced component count. These parameter adjustments ensure that the simplified circuit maintains equivalent driving capability and process margin despite having fewer transistors and capacitors.
