Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical electronic devices are disposed on the front surface of the display panel, then they can be easily accessed and function normally, but the display area is reduced and image quality deteriorates
Solution Approach 1:
The patent moves the optical electronic device from the front surface (2D plane) to the back surface of the display panel, utilizing the third dimension (depth/layer) to resolve the conflict between device functionality and display area. This dimensional transition allows the optical device to be positioned in the non-display area without reducing the front display surface.
Solution Approach 2:
The optical electronic device is nested within the display panel structure itself, specifically in the non-display area on the back surface. This nesting approach integrates the optical device into the existing panel architecture, allowing it to function without occupying additional space that would reduce the display area.
2Reliability
If optical electronic devices are disposed on the front surface of the display panel, then they can be easily accessed, but image quality deteriorates due to obstruction and light interference
Solution Approach 1:
By relocating the optical electronic device to the back surface of the display panel, the patent eliminates the physical obstruction and light interference that occur when devices are placed on the front surface. This dimensional change ensures that the optical device does not block light paths or interfere with the display optics, thereby maintaining image quality.
3Area of stationary object
If the non-display area is reduced to maximize display area, then the display area increases, but optical electronic devices cannot be properly positioned or function
Solution Approach 1:
The patent resolves this contradiction by utilizing the back surface of the display panel as the positioning location for optical electronic devices. This dimensional transition allows the devices to be placed in the non-display area without requiring additional front surface space, thereby maintaining maximum display area while ensuring proper device positioning and functionality.
4Reliability
If optical electronic devices are positioned under the display area with light transmission structure, then they can function normally and remain hidden, but the structure becomes more complex
Solution Approach 1:
The patent integrates the optical electronic device within the existing display panel structure on the back surface, nesting it into the non-display area. This approach utilizes the existing structural layers and components of the display panel, minimizing the need for additional complex structures while enabling the optical device to function and remain hidden from the front surface.
