Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple non-planar display devices are coupled together to achieve three-dimensional structure variation, then design flexibility is improved, but device complexity increases
Solution Approach 1:
The display device is divided into multiple independent display modules, each capable of being controlled separately. This segmentation allows the device to achieve three-dimensional structure variation without coupling multiple complete display devices, thereby reducing overall device complexity while maintaining design flexibility.
Solution Approach 2:
The patent introduces a new dimension of control by adding a third scan line set that operates independently from the traditional row and column scan lines. This enables the display device to achieve three-dimensional structure variation within a single integrated device, avoiding the need to couple multiple devices together.
2Adaptability or versatility
If non-planar substrates are used to achieve diverse shapes, then adaptability is improved, but image uniformity deteriorates
Solution Approach 1:
The patent implements dynamic control of pixel units through independent scan line sets, allowing real-time adjustment of display parameters across different regions. This dynamic control compensates for the non-planar substrate's irregularities, maintaining image uniformity while supporting diverse shapes.
Solution Approach 2:
Different regions of the display device can be controlled independently through the third scan line set, allowing local adjustment of display characteristics. This enables each region to be optimized for its specific position on the non-planar substrate, maintaining overall image uniformity across the entire display area.
3Adaptability or versatility
If pixel units are distributed on non-planar substrates, then shape versatility is improved, but uniformity of pixel distribution deteriorates
Solution Approach 1:
The independent control of pixel units through multiple scan line sets enables dynamic adjustment of pixel activation and timing. This dynamic control compensates for non-uniform pixel distribution on non-planar substrates, ensuring uniform visual output despite variations in physical pixel spacing.
Data Source
AI summary
A display device is provided. A data line includes a main line section, a first line section and a second line section spaced apart from one another. The first and second line sections respectively cross over a first scan line set to form first and second crossing regions. The main line section crosses over a second scan line set to form third crossing regions. The first line section is electrically connected to the main line section and one scan line of a third scan line set via a first switch element. The second line section is electrically connected to the main line section and another scan line of the third scan line set via a second switch element. First pixel units, second pixel units and third pixel units correspond respectively to the first crossing regions, the second crossing regions and the third crossing regions.
