Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high manufacturing cost of driving structures for LEDs, mini LEDs, and micro LEDs is attributed to the complexity of circuits with densely distributed switch elements.
Innovation Solution
A method of generating a composite signal with one-to-one correspondence between sub-messages and pixel groups, allowing direct loading of data messages to corresponding sub-pixels without the need for a gate driving circuit, gate line, or transistors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple switch elements are used in each sub-pixel with gate driving circuits and gate lines, then the luminescent function can be realized, but the circuit becomes complicated and element density increases, leading to high manufacturing cost
Solution Approach 1:
The patent extracts and removes the gate driving circuit, gate line, and transistor from the traditional driving structure. Instead of using multiple switch elements controlled by gate signals, the invention uses a single switch element per sub-pixel that is directly controlled by data signals, thereby eliminating the complicated gate driving circuitry while maintaining the luminescent function
Solution Approach 2:
The data signal serves multiple functions: it directly controls the switch element and simultaneously provides the drive signal for luminescence. This multi-functionality eliminates the need for separate gate control signals and gate driving circuits, simplifying the overall structure while achieving the same luminescent effect
2Reliability
If multiple switch elements and gate driving circuits are densely distributed, then the luminescent function is achieved, but the element density increases, leading to high manufacturing cost
Solution Approach 1:
The patent removes the gate line and transistor components from the dense circuit structure, reducing the quantity of elements that need to be manufactured and assembled. Each sub-pixel retains only the essential switch element and luminescent component, significantly reducing element density while preserving luminescent functionality
Solution Approach 2:
The patent segments the driving function into individual sub-pixel units, where each sub-pixel operates independently with its own switch element controlled by dedicated data signals. This segmentation eliminates the need for shared gate lines and transistors, reducing overall element density
