Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple output lines are used in the data driving circuit, then each data line can be independently controlled, but the manufacturing cost increases
Solution Approach 1:
The data lines are divided into multiple groups, with each group controlled by a separate output line. The data distributor selectively connects output lines to data line groups based on control signals, enabling independent control of multiple data lines through fewer output lines. This segmentation approach reduces the total number of output lines required while maintaining the capability to independently control different data line groups.
Solution Approach 2:
The data distributor dynamically reconfigures the connection between output lines and data lines based on control signals. By selectively connecting different output lines to different data line groups at different times, the system achieves flexible control with fewer permanent connections, thereby reducing manufacturing complexity and cost while preserving adaptability.
2Area of stationary object
If multiple data lines are arranged closely together, then the display area is maximized, but interference between adjacent data lines increases causing image quality degradation
Solution Approach 1:
Data lines are divided into multiple groups that are controlled independently. By selectively activating specific data line groups based on the display content requirements, the system reduces the number of simultaneously active data lines, thereby minimizing interference between adjacent data lines while maintaining maximum display area utilization.
Solution Approach 2:
The data distributor alternately activates different groups of data lines in a periodic manner based on control signals. This time-division multiplexing approach ensures that not all data lines are active simultaneously, reducing electromagnetic interference between adjacent data lines while maintaining efficient use of the display area.
