Solution Overview
Problem
The complexity of wiring in Micro-LED display panels due to multiple line channels increases design costs and reduces available area, making it challenging for the development of these panels.
Innovation Solution
A delay component is added between the line pipe control component and micron-level light-emitting components, allowing a single line channel to control multiple light-emitting components, reducing the number of line channels and simplifying the wiring without affecting the panel's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple line channels are extended from each line pipe control component to connect to corresponding micron-level light-emitting components, then each light-emitting component can receive enable signals and collect column data signals, but the wiring becomes complex, increasing design cost and reducing available area
Solution Approach 1:
The patent merges multiple line channels into a single shared line channel that connects the line pipe control component to multiple delay components. Each delay component then independently controls corresponding micron-level light-emitting components, eliminating the need for separate line channels for each component while maintaining reliable signal transmission.
Solution Approach 2:
The patent introduces delay components as intermediary elements between the shared line channel and the micron-level light-emitting components. These delay components receive the enable signal through the shared line channel, process it with appropriate timing delays, and then control the light-emitting components, thereby simplifying the wiring structure while ensuring proper signal timing for each component.
2Reliability
If multiple line channels are extended from each line pipe control component, then complete control signals can be provided to each light-emitting component, but the available area of the display panel is reduced
Solution Approach 1:
The patent combines multiple separate line channels into a single shared line channel that serves multiple delay components and their corresponding light-emitting components. This merging reduces the total wiring area required on the display panel while maintaining complete control signal delivery through the delay components' timing functionality.
Solution Approach 2:
The patent resolves the area constraint by transitioning from a direct one-to-one connection architecture to a hierarchical architecture with intermediate delay components. This dimensional change in the control architecture allows signals to be distributed to multiple components through a shared channel, effectively reducing the wiring area while preserving control completeness.
3Adaptability or versatility
If multiple line channels are extended from each line pipe control component, then each light-emitting component can be independently controlled, but the design cost increases
Solution Approach 1:
The patent makes the shared line channel universal by enabling it to serve multiple delay components and their corresponding light-emitting components simultaneously. The delay components provide multi-functionality by handling both signal distribution and timing control, thereby maintaining independent control capability while reducing the overall system complexity and design cost.
Solution Approach 2:
The delay components act as universal intermediaries that can interface between the shared line channel and multiple different micron-level light-emitting components. This intermediary approach allows a single line channel design to control multiple components independently, reducing design cost while preserving adaptability.
