Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional GOA circuit configuration is used, then the scanning driving function is achieved, but the circuit complexity becomes too high and it cannot adapt to ultra-narrow bezel requirements
Solution Approach 1:
The driving circuit is divided into multiple driving units arranged in an array, where each driving unit independently generates scanning signals for its corresponding column. This segmentation allows the circuit to adapt to narrow bezel designs while maintaining manageable complexity through modular architecture.
Solution Approach 2:
Each driving unit is designed as a universal module that can generate both forward scanning signals and reverse scanning signals, and can drive multiple pixel columns. This multi-functionality reduces overall circuit complexity while enabling adaptation to various display panel configurations including ultra-narrow bezel designs.
2Adaptability or versatility
If the driving circuit is simplified to meet ultra-narrow bezel requirements, then adaptability is improved, but signal stability and reliability may be compromised
Solution Approach 1:
The driving circuit incorporates preliminary signal preparation stages including signal generation, inversion, and buffering before the actual scanning signal is applied to the pixel columns. This preliminary action ensures signal stability is maintained even in the simplified circuit configuration required for ultra-narrow bezel displays.
Solution Approach 2:
Buffer units and signal inversion units are introduced as intermediary components between the driving units and the pixel array. These intermediaries ensure reliable signal transmission and maintain signal integrity, preventing reliability degradation despite circuit simplification.
