Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mini-LEDs and micro-LEDs are combined with touch function in active light emission form, then display capabilities and functionality are improved, but device complexity increases
Solution Approach 1:
The patent combines mini-LEDs/micro-LEDs with touch electrode structures and thin film transistors on a single substrate, integrating display, lighting, and touch sensing functions into one unified device structure, thereby improving versatility while managing complexity through functional integration
Solution Approach 2:
The touch electrode structures serve dual purposes: as touch sensing elements and as electrode connections for the LED components. The alternating arrangement of first and second electrodes enables both capacitive touch sensing and electrical connection to the LEDs, achieving multi-functionality with shared components
2Productivity
If touch electrode structures and thin film transistor structures are integrated in the same layer, then manufacturing efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent forms touch electrode structures and thin film transistor structures in the same manufacturing layer, allowing simultaneous fabrication of both components through unified processing steps, which improves manufacturing efficiency by reducing the number of separate fabrication processes
Solution Approach 2:
The manufacturing process is divided into distinct regions: a display area with alternating first and second electrodes for touch sensing and LED connection, and a non-display area with thin film transistors for signal processing, allowing specialized optimization of each region while maintaining integrated manufacturing
