Engineering Contradiction Analysis
1Measurement precision
If the number of pixels is increased to improve resolution, then the resolution is improved, but the space available for each pixel is reduced and power consumption increases
Solution Approach 1:
The display is segmented into multiple display regions (first display region and second display region) with different pixel configurations. The first display region uses a conventional pixel arrangement, while the second display region uses a different pixel arrangement with shared data lines. This segmentation allows different areas to have different power consumption characteristics, enabling the system to achieve high resolution overall while controlling total power consumption by activating only necessary regions at different times.
Solution Approach 2:
The display device implements periodic switching between different display modes. In the first display mode, the first display region is activated with its dedicated data lines. In the second display mode, the second display region is activated with shared data lines. This periodic action allows the system to achieve high resolution by alternating between regions while reducing power consumption by keeping only one region active at a time rather than all pixels continuously powered.
2Measurement precision
If more data lines are added to support higher resolution, then the resolution is improved, but the device complexity increases
Solution Approach 1:
The data lines in the second display region are designed to serve multiple functions. The same data lines are used to drive pixels in different display regions at different times (first display mode and second display mode). This multi-functionality reduces the total number of data lines required compared to a conventional design where each pixel would have dedicated lines, thereby reducing device complexity while maintaining high resolution capability.
Solution Approach 2:
The data line configuration is made dynamic through the switching between display modes. The system dynamically assigns data lines to different pixel groups depending on which display region is currently active. This dynamic allocation allows the same physical data lines to serve different logical purposes at different times, reducing the overall complexity of the data line network while supporting high resolution display.
3Measurement precision
If pixels are arranged densely to improve resolution, then the resolution is improved, but the viewing angle control becomes difficult
Solution Approach 1:
Different display regions are given different local qualities in terms of pixel arrangement and data line configuration. The first display region has a conventional pixel arrangement optimized for certain viewing characteristics, while the second display region has a different arrangement with shared data lines that provides different viewing angle characteristics. This local quality differentiation allows the overall display to achieve high resolution while providing controlled viewing angles through the specific configuration of each region.
