Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate panels are used to make the double-sided display, then the display function is achieved, but the number of bindings increases and the structure becomes more complicated
Solution Approach 1:
The patent merges two separate display panels into a single integrated double-sided display panel. The first and second display modules are bonded together with their thin film transistor substrates facing each other, sharing a common driving module and circuit board. This merging reduces the number of bindings from two to one and simplifies the overall structure while maintaining the double-sided display function.
2Adaptability or versatility
If two separate panels are used to make the double-sided display, then the display function is achieved, but two separate circuit boards are required which increases cost
Solution Approach 1:
The patent combines the driving modules of two separate panels into a single shared driving module. The circuit board integrates driving circuits for both the first and second display modules, eliminating the need for two separate circuit boards. This reduces material costs, assembly costs, and overall manufacturing complexity while maintaining full display functionality on both sides.
3Adaptability or versatility
If two separate panels are used to make the double-sided display, then the display function is achieved, but the display performance is affected
Solution Approach 1:
The patent integrates two display modules into a single bonded structure with shared driving circuits and signal transmission paths. This unified structure improves display performance by ensuring consistent signal quality, reducing interference between separate systems, and providing better mechanical stability. The bonded interface between thin film transistor substrates ensures reliable signal transmission while maintaining display quality on both sides.
