Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external sensor units are used for sensing in display apparatuses, then sensing coverage can be achieved, but sensing precision is compromised and device complexity increases
Solution Approach 1:
The patent merges the display function and sensing function into a single integrated device. The display apparatus includes a display unit with a sensing unit disposed on its front surface, allowing the display screen itself to perform sensing operations. This integration eliminates the need for separate external sensor units while improving sensing precision through direct contact with the display surface.
2Adaptability or versatility
If multiple light sensors are integrated within the display apparatus, then sensing variety and precision are improved, but device complexity increases
Solution Approach 1:
The sensing unit is designed with multiple light sensors that can perform various sensing functions including touch sensing, ambient light sensing, and 3D image sensing. This multi-functional design allows a single sensing unit to replace multiple separate sensing devices, achieving sensing variety while actually reducing overall device complexity through functional integration.
Solution Approach 2:
The patent introduces a light-transmissible electrode unit with multiple electrode lines that work together with the light sensors to enable sensing in different dimensions and modes. This allows the system to detect various types of light (ambient and emitted) and perform different sensing operations without adding proportional complexity.
3Measurement precision
If light sensors are added to the display apparatus, then sensing capabilities are enhanced, but the display image quality may be affected
Solution Approach 1:
The sensing unit is disposed on the front surface of the display unit in a localized manner, with light sensors and electrode lines positioned to perform sensing functions without covering the entire display area. This allows the display image to maintain its quality in non-sensing regions while enabling precise sensing in specific areas where the sensing unit is integrated.
Solution Approach 2:
The patent introduces a light-transmissible electrode unit as an intermediary component between the light sensors and the display image. This electrode unit allows light to pass through while providing electrical connections for the sensors, ensuring that the sensing components do not directly interfere with the display image quality.
