Display Panel Cutting Rulers for Non-Rectangular Border Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturers face challenges in ensuring the shape of display panels meets design standards and guarantees compatibility with other electronic device elements, particularly in non-rectangular devices, where existing methods lack effective methods to verify border accuracy and adjust cutting operations accordingly.
Innovation Solution
The use of cutting rulers disposed adjacent to the border of display panels, with specific equations determining the number of cutting rulers based on the number of curved and straight edges, inflection points, and angles, to ensure accurate cutting and compliance with design requirements, whether in one-cut or multi-cut operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel uses non-rectangular shapes to adapt to portable electronic devices, then the adaptability of the display panel is improved, but the difficulty of examining shape compliance and guaranteeing compatibility increases
Solution Approach 1:
The patent introduces cutting rulers as intermediary measurement tools that are disposed adjacent to the border of the display panel. These rulers provide reference markings that facilitate the examination of whether the curved and straight edges of the non-rectangular display panel meet design standards, thereby reducing the difficulty of detecting and measuring shape compliance.
2Adaptability or versatility
If the border of the display panel includes multiple curved edges and straight edges to achieve complex shapes, then the adaptability is improved, but the number of cutting rulers required increases
Solution Approach 1:
The patent segments the border of the display panel into distinct curved edges and straight edges, and correspondingly segments the measurement system into multiple cutting rulers. Each cutting ruler is responsible for measuring specific portions of the border, allowing for precise measurement of complex shapes while organizing the measurement process into manageable segments.
Solution Approach 2:
The cutting rulers are disposed adjacent to the border in advance before the cutting operation. This preliminary positioning of measurement tools allows for pre-planning of the cutting path and ensures that all necessary measurement references are in place before the actual cutting begins, facilitating efficient processing of complex shapes.
3Manufacturing precision
If cutting rulers are disposed adjacent to the border for precise measurement, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The cutting rulers serve as simplified copies or representations of the ideal border geometry. By disposing these rulers adjacent to the actual border, the complex measurement task is reduced to comparing the physical border against the simplified reference markings on the rulers, thereby achieving high manufacturing precision without requiring complex measurement equipment.

AI summary
A display panel is provided. The display panel includes a substrate and a plurality of cutting rulers. The substrate includes a non-display area and a border surrounding the non-display area. The border includes at least one curved edge and at least one straight edge. The cutting rulers are disposed adjacent to the border. The numbers of the cutting rulers are determined according to the accuracy requirements and the shape of the display panel to meet various needs and improve productivity and product yield.
