Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable blocking device or color changing layer is added to switch between transparent and non-transparent display modes, then the display mode switching function is achieved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the light blocking function from external detachable devices or separate color changing layers and integrates it directly into the display panel structure. The light blocking parts are formed within the display panel itself, eliminating the need for separate blocking devices and simplifying the overall system structure while maintaining the dual-mode display capability
Solution Approach 2:
The patent merges the light blocking function with the existing display panel structure by integrating light blocking parts into the array substrate or color filter substrate. This combination eliminates separate components and reduces device complexity while achieving the same functional result
2Adaptability or versatility
If a detachable blocking device or color changing layer is added to switch between transparent and non-transparent display modes, then the display mode switching function is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the light blocking function with the existing display panel manufacturing process. The light blocking parts are formed using the same thin film deposition and patterning techniques already employed for other display components, eliminating the need for separate manufacturing steps and reducing overall production costs
Solution Approach 2:
The light blocking parts serve multiple functions: they block light in non-transparent mode, define pixel boundaries, and can be integrated with color filter structures. This multi-functionality reduces the need for additional components and lowers manufacturing costs
3Adaptability or versatility
If a detachable blocking device or color changing layer is used for switching display modes, then the transparent and non-transparent states can be achieved, but the switching operation becomes complicated and efficiency decreases
Solution Approach 1:
The patent replaces mechanical blocking devices that require physical attachment/detachment or manual operation with an electrically controlled system. The light blocking parts are controlled through electrical signals applied to the gate lines, enabling simple and rapid switching between transparent and non-transparent modes without mechanical intervention
Solution Approach 2:
The patent creates a dynamically controllable display system where the light blocking function can be rapidly switched on and off through electrical signals. The gate line scanning mechanism allows dynamic control of the light blocking parts, enabling fast mode switching that adapts to user needs in real-time
