Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light emitting diodes are used to achieve faster lighting speed and superior light emitting efficiency, then light emission performance is improved, but light loss inside the display panel increases
Solution Approach 1:
The patent converts the harmful effect of light being trapped inside the panel by introducing a mirror wall structure. The mirror wall reflects downward-directed light back upward through the display panel, transforming light that would otherwise be lost into useful emitted light, thereby improving overall light emission efficiency
Solution Approach 2:
The patent introduces a vertical dimension solution by placing a mirror wall at the bottom of the display panel. This allows light management in the vertical direction (reflecting light upward) to complement the horizontal light extraction, creating a three-dimensional light management system that improves overall light emission
2Adaptability or versatility
If multiple drivers are used to control light emitting devices, then driving capability is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent merges the functions of multiple drivers into a single driver by implementing a matrix wiring structure where row lines and column lines intersect to form pixel elements. This allows one driver to control multiple row lines and another to control multiple column lines, with their intersections providing the multiplexed control capability that previously required multiple separate drivers
Solution Approach 2:
The row lines and column lines serve multiple functions simultaneously: they provide electrical connection to light emitting devices, enable multiplexed scanning control, and facilitate simple driver architecture. This multi-functionality reduces the need for dedicated drivers for each light emitting device while maintaining full control capability
3Adaptability or versatility
If multiple drivers are used to control light emitting devices, then driving capability is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent merges multiple driver functions into a unified matrix wiring structure that can be manufactured as an integrated circuit. This integration reduces the number of discrete components and assembly steps required, simplifying the manufacturing process while maintaining the capability to control multiple light emitting devices through row and column scanning
