Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If uniform heating electrodes are used across the entire first substrate, then the heating structure is simple, but the temperature distribution becomes non-uniform due to faster heat dissipation at peripheral portions
Solution Approach 1:
The heating electrode layer is divided into different regions with different heating powers: a first region closer to the side edge with higher heating power, and a second region farther from the side edge with lower heating power. This local differentiation compensates for the faster heat dissipation at peripheral portions, achieving uniform temperature distribution across the liquid crystal display panel.
Solution Approach 2:
The heating electrode layer is segmented into multiple heating electrodes arranged in different regions. Each heating electrode or group of heating electrodes can be independently controlled with different heating powers, allowing precise local temperature control to address the non-uniform heat dissipation characteristics of different panel regions.
2Loss of time
If heating power is increased to improve heating efficiency, then response time is reduced, but energy consumption increases
Solution Approach 1:
The heating power of different heating electrodes is optimized based on their respective regions. The first heating electrodes in regions closer to side edges operate at higher power to compensate for heat loss, while heating electrodes in central regions operate at lower power. This parameter optimization achieves fast response time while minimizing overall power consumption.
