Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in providing a convenient and reliable solution for integrating terminal regions without obstructing the display area, maintaining light-transmitting properties, and enabling seamless alignment with other display panels while ensuring high-quality display performance.
Innovation Solution
The display panel design includes a terminal region that overlaps with the display region, allowing terminals to be positioned on the rear surface without blocking the display, with signal lines and driver circuits strategically connected to enable efficient signal distribution and image synchronization across multiple panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If terminal regions are positioned on the rear surface overlapping with the display region, then terminals can be hidden from view and light-transmitting properties are maintained, but terminal region integration and alignment with other panels become more complex
Solution Approach 1:
The terminal region is moved from the conventional edge position to the rear surface, utilizing the Z-dimension (depth) to resolve the conflict between terminal accessibility and display area occupancy. This spatial reconfiguration allows terminals to be positioned at coordinates (x, y, -z) where they overlap with the display region in the XY plane but remain accessible from the rear, effectively hiding them from front view while maintaining electrical connectivity.
Solution Approach 2:
The terminal region is nested within the display region's spatial footprint by positioning it on the rear surface. The terminal region acts as a nested structure that occupies the same projected area as the display region but exists in a different depth plane, allowing both functions to coexist without mutual interference.
2Adaptability or versatility
If signal lines are extended to connect first and second terminals through the display region, then signal distribution is enabled, but display quality may be compromised by the presence of signal lines
Solution Approach 1:
The signal line is designed with spatially varying properties: in regions where it traverses the display area, the line width is minimized or the line is routed through transparent/conductive oxide layers that are optically invisible, while in terminal connection regions, the line width is maximized for optimal electrical connectivity. This local differentiation allows the same signal line to satisfy both optical and electrical requirements.
Solution Approach 2:
A transparent conductive oxide layer serves as an intermediary medium that carries signal lines through the display region without compromising visual quality. This intermediate layer acts as a bridge between the electrical signal transmission function and the optical transparency requirement, allowing signals to pass through while maintaining display clarity.
