Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transmissive liquid crystal display device with backlight is used, then high visibility is achieved, but power consumption increases
Solution Approach 1:
The display device is divided into multiple display regions (first, second, third regions) with different display mechanisms. The first display region uses reflective liquid crystal elements for low power consumption, while the second and third display regions use light-emitting elements for high visibility, allowing the system to segment the display function across different technologies
Solution Approach 2:
Different portions of the display device have different optical properties and functions. The first display region has reflective properties optimized for outdoor visibility, while the second and third display regions have light-emitting properties optimized for indoor or dark environment visibility, making each local area suitable for its specific viewing conditions
2Use of energy by moving object
If a reflective liquid crystal display device is used, then power consumption is reduced, but visibility in low light conditions deteriorates
Solution Approach 1:
The display device is divided into multiple display regions (first, second, third regions) with different display mechanisms. The first display region uses reflective liquid crystal elements for low power consumption, while the second and third display regions use light-emitting elements for high visibility, allowing the system to segment the display function across different technologies
Solution Approach 2:
The display device achieves multi-functionality by incorporating both reflective and light-emitting display regions, enabling it to operate effectively in both bright outdoor conditions (using reflective region) and dark indoor conditions (using light-emitting regions), thus serving multiple viewing environments with a single device
3Device complexity
If display is limited to a single surface, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The display device extends from a single-plane configuration to a multi-dimensional configuration by adding side surfaces as display regions. The second display region is provided on a side surface of the housing, and the third display region is provided on another side surface, transforming the display from a two-dimensional single surface to a three-dimensional multi-surface structure
Solution Approach 2:
The display function is segmented across multiple spatial locations and surfaces. The first display region is on the top surface, the second display region is on one side surface, and the third display region is on another side surface, distributing the display functionality across different spatial dimensions and surfaces of the housing

AI summary
A display device includes a first region and a second region adjacent to the first region. A display element included in the first region has a function of reflecting visible light and a function of emitting visible light. A display element included in the second region has a function of emitting visible light. In an electronic device including the display device, the first region is located on a first surface (e.g., top surface) on which a main image is displayed, and the second region is located on a second surface (e.g., side surface) on which an auxiliary image is displayed.
