Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a light transmitting display area is integrated with a transition display area in full-screen mobile devices, then the front visible area is increased and display quality is improved, but the integration seamless is difficult to achieve and display continuity is affected
Solution Approach 1:
The display area is segmented into a light transmitting display area and a transition display area, with the transition display area further divided into multiple sub-regions. This segmentation allows each area to be optimized independently while maintaining overall integration, solving the contradiction by enabling precise control of display parameters in different zones to achieve seamless integration.
Solution Approach 2:
Different display qualities and parameters are applied to different regions: the light transmitting area uses one set of display parameters while the transition area uses another. This local quality approach allows the light transmitting area to maintain high visibility while the transition area provides gradual adaptation, resolving the integration seamless issue.
2Stability of the object's composition
If sub-pixels in the transition area are electrically connected to ensure synchronized display, then display continuity is improved, but the device complexity increases due to specific scan line and data line configuration
Solution Approach 1:
The scan lines and data lines for the light transmitting display area and the transition display area are merged and shared. By using common scan lines and data lines for both areas, the patent reduces the overall number of signal lines required while maintaining synchronized display control, thus improving display continuity without proportionally increasing device complexity.
Solution Approach 2:
The scan lines and data lines are designed to serve multiple functions: they control both the light transmitting display area and the transition display area. This multi-functionality allows a single set of signal lines to manage different display regions with different requirements, reducing overall system complexity while ensuring display continuity.
3Manufacturing precision
If pixel density is maintained across light transmitting and transition areas, then display quality is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent adjusts display parameters such as pixel density, brightness, and refresh rate differently for the light transmitting area and the transition area. By changing these parameters locally rather than uniformly, the system maintains optimal pixel density in each region while accounting for manufacturing variations, thus enhancing display quality without excessively increasing manufacturing precision requirements.
