Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional dielectric materials are used in the passivation layer of GOA circuits, then the structural integrity and protection function are maintained, but the capacitance value remains high leading to excessive circuit load and high power consumption
Solution Approach 1:
The patent changes the dielectric constant parameter of the passivation layer material from conventional high dielectric constant materials to low dielectric constant materials (such as organic materials with dielectric constant less than 3.9), thereby reducing the capacitance value of the GOA circuit and lowering power consumption while maintaining circuit reliability
Solution Approach 2:
The patent employs composite material structures in the passivation layer, combining organic low dielectric constant materials with inorganic materials to achieve both low capacitance and high structural reliability, resolving the contradiction between energy efficiency and circuit load capacity
2Reliability
If the passivation layer thickness is increased to improve protection, then the protective function is enhanced, but the capacitance value increases further exacerbating the circuit load
Solution Approach 1:
The patent changes the material parameter (dielectric constant) rather than relying solely on thickness adjustment, using low dielectric constant materials that provide adequate protection at reduced thickness levels, thereby simultaneously improving protection function while reducing capacitance value and circuit load
