Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If each pixel unit is driven by a dedicated pixel driving chip, then the display control precision is improved, but the device complexity and fabrication difficulty increase
Solution Approach 1:
The display panel is segmented into multiple pixel units, each with its own pixel driving chip. This segmentation allows independent control of each pixel unit, improving display control precision while enabling modular fabrication processes that can reduce overall complexity through standardized repeating units.
Solution Approach 2:
Each pixel driving chip is designed as a universal module that can drive multiple sub-pixels (including different color sub-pixels) within a pixel unit. This multi-functionality reduces the need for different specialized chips for different pixel types, simplifying the fabrication process while maintaining precise control.
2Manufacturing precision
If multiple pixel driving chips are used to drive pixel units, then the display control precision is improved, but the transmission bandwidth requirement increases
Solution Approach 1:
Multiple data lines are merged into a single data line that sequentially serves multiple pixel driving chips. The pixel driving chips are controlled to operate in a time-division manner, allowing one data line to provide data to multiple chips at different time intervals. This merging reduces the total number of data lines required, decreasing transmission bandwidth requirements while maintaining precise control through coordinated timing.
Solution Approach 2:
The system employs periodic action by sequentially activating different pixel driving chips in a time-division multiplexing scheme. Each pixel driving chip receives data during its designated time slot and holds the data until needed, creating a periodic pattern of data transmission that reduces instantaneous bandwidth requirements while maintaining continuous display control.
3Device complexity
If pixel driving chips are divided into portions with shared gate lines, then the device complexity is reduced, but the control precision may be compromised
Solution Approach 1:
The system uses dynamic control where pixel driving chips within the same gate line group are activated in a specific sequence rather than simultaneously. The control component dynamically manages the timing and order of activation for each pixel driving chip, ensuring that even though they share gate lines, each chip receives precise control signals at the appropriate time, maintaining control precision while reducing structural complexity.
