Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display range is increased, then the visual effect is improved, but the area occupied by the bezel is reduced
Solution Approach 1:
The patent merges the timing controller and data driver into a single integrated device. The timing controller generates timing signals that are directly used by the data driver without requiring external synchronization signals, eliminating the need for additional synchronization wiring in the bezel area. This integration reduces the bezel area while maintaining the display range.
Solution Approach 2:
The integrated device performs multiple functions: it generates timing signals, processes display data, and drives the display panel all within a single unit. The timing controller and data driver share common functional resources, allowing the system to maintain full functionality with reduced hardware footprint and smaller bezel area.
2Area of moving object
If the display range is increased, then the visual effect is improved, but the area for configuring hardware elements and circuit wirings is reduced
Solution Approach 1:
The patent combines the timing controller and data driver into one integrated device, reducing the number of separate hardware elements that need to be configured. This merger decreases the area required for hardware configuration and simplifies the circuit wiring, as the integrated device internally manages timing signal distribution without requiring extensive external wiring.
3Productivity
If multiple data drivers are used to drive the display, then the pixel driving capability is improved, but additional synchronization signals are required
Solution Approach 1:
The integrated timing controller and data driver device can drive multiple display panels simultaneously using a single device. The timing controller generates timing signals that are distributed internally to multiple data driver outputs, enabling multi-panel driving without requiring additional synchronization signals between separate data drivers, thus maintaining high pixel driving capability while reducing system complexity.
