Curved Electro-Optical Device Circuit Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-optical devices face challenges in miniaturization due to the large size of the outside area of the pixel area, caused by the straight-line disposition of scanning line driving circuits, leading to uneven voltage distribution and image quality issues.
Innovation Solution
The electro-optical device incorporates a signal output circuit that can be disposed along irregular outer peripheral edges of the pixel area, including curved or bent portions, allowing for a more compact design without increasing the width of the outside area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the scanning line driving circuit is disposed in a straight line in the direction of the data lines, then the circuit layout is simple, but the outside area of the pixel area must be formed to have a large width, causing the device size to become large
Solution Approach 1:
The pixel area outer peripheral edge is formed with a curved shape instead of a straight line, allowing the scanning line driving circuit to be disposed along the curved edge. This curvature enables the circuit to follow the boundary of the pixel area, reducing the required width of the outside area while maintaining circuit functionality and simplifying the overall layout.
2Device complexity
If the scanning line driving circuit is disposed in a straight line, then the circuit structure is simple, but uneven voltage distribution occurs leading to image quality issues
Solution Approach 1:
The curved shape of the pixel area outer peripheral edge allows the scanning line driving circuit to be positioned at a more uniform distance from the pixel area. This curved arrangement equalizes the electrical path lengths and reduces voltage distribution variations across the circuit, thereby improving image quality without increasing structural complexity.
