Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional functions are integrated within the display area, then functionality is improved, but light transmittance and image quality deteriorate
Solution Approach 1:
The display panel is divided into a display area and a peripheral area, with sub-pixel circuits segregated to the peripheral area. This segmentation allows the display area to be dedicated to light emission and transmission, while the peripheral area houses the circuitry, thus maintaining high light transmittance in the display area while integrating additional functions in the peripheral area.
Solution Approach 2:
The patent utilizes the peripheral area as an additional spatial dimension to integrate sub-pixel circuits and other components. By moving circuits from the display area to the peripheral area, the display area remains optimized for light transmission, while the peripheral area provides space for additional functionalities without compromising image quality.
2Reliability
If sub-pixel circuits are arranged in the display area, then electrical connection is improved, but light transmittance and display area coverage deteriorate
Solution Approach 1:
The patent segments the panel into display area and peripheral area, placing sub-pixel circuits in the peripheral area. This segmentation ensures that the display area is fully dedicated to light emission and transmission, maximizing display area coverage, while the peripheral area provides sufficient space for electrical connections and circuitry.
Solution Approach 2:
Conductive bus lines are introduced as intermediaries to connect sub-pixel circuits in the peripheral area with light-emitting elements in the display area. These bus lines efficiently transmit electrical signals across the bending area, ensuring reliable electrical connection without occupying display area space.
3Adaptability or versatility
If the display panel is made flexible with a bending area, then adaptability is improved, but structural stability and manufacturing complexity worsen
Solution Approach 1:
The patent applies local quality by creating a bending area with specific structural characteristics in the peripheral area, while maintaining a rigid structure in the display area. The bending area is designed with appropriate thickness and material properties to allow flexibility, while the display area maintains structural stability for high-quality light transmission and image display.
Solution Approach 2:
The display panel is segmented into a rigid display area and a flexible peripheral area with a bending area. This segmentation allows the panel to achieve flexibility where needed while maintaining structural stability in the display area, thereby reducing overall manufacturing complexity compared to making the entire panel flexible.
4Weight of moving object
If thickness and weight are reduced, then portability is improved, but structural strength and component integration capability worsen
Solution Approach 1:
The patent employs composite materials with appropriate mechanical properties to achieve reduced thickness and weight while maintaining structural strength. The substrate and various layers are selected and designed to provide sufficient strength for component integration and handling, despite the reduced overall thickness of the display panel.
Solution Approach 2:
By segmenting the panel into display area and peripheral area, the patent can optimize thickness distribution - making the display area thinner for weight reduction while maintaining adequate thickness in the peripheral area for structural support and component housing, thus achieving weight reduction without compromising structural strength.
