Touch Substrate Cutting for Special Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of developing masks for touch products with special sizes and aspect ratios lead to inefficiencies in meeting small batch demands, making it difficult to produce touch screen products with both display and touch interaction functions efficiently.
Innovation Solution
A touch substrate manufacturing method that involves cutting a touch substrate of a conventional size to create a target substrate of a specific size without the need for a new mask, by adjusting the connection manner of the flexible printed circuit and touch IC, and potentially adjusting the film thickness of conductive materials to meet the required resistance values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mask plate is developed separately for each special size and aspect ratio touch product, then the display region requirements can be met, but the development cost increases significantly and profitability cannot be guaranteed for small batch demands
Solution Approach 1:
The patent applies universality by using a single standardized mask plate design that can accommodate multiple different touch substrate sizes and aspect ratios. The mask plate is designed with a universal structure that allows it to serve various product configurations without requiring separate mask developments for each size, thereby reducing development costs while maintaining adaptability to different display region requirements.
Solution Approach 2:
The patent segments the touch substrate manufacturing process by separating the mask plate development from the substrate size customization. The standardized mask plate handles the common patterning functions while the substrate size and aspect ratio variations are managed through other means such as substrate selection and positioning, thereby reducing the complexity of mask development.
2Manufacturing precision
If a new mask plate is developed for each special size touch product, then the specific size requirements can be satisfied, but the production cycle increases and market responsiveness decreases
Solution Approach 1:
The patent applies preliminary action by pre-developing and standardized mask plates that can be immediately used for production. Instead of developing new masks for each custom size requirement, the standardized masks are prepared in advance and can be quickly applied to different substrate sizes, thereby reducing the production cycle time while maintaining manufacturing precision through the standardized design.
Solution Approach 2:
The universal mask plate design allows the same mask to serve multiple product configurations, eliminating the need for time-consuming mask developments for each size variation. This multi-functional approach enables faster production cycle while maintaining the required precision for different touch substrate sizes.
3Ease of operation
If touch and display functions are integrated in the same device, then user experience is improved, but the demand for such integrated products remains insufficient compared to separate display products
Solution Approach 1:
The patent applies universality by developing a standardized mask plate system that can serve both display and touch functionality. The same standardized mask can be used for producing touch substrates with different sizes and aspect ratios, enabling the manufacturing of integrated touch-display products without requiring separate specialized masks, thereby supporting the production of multi-functional devices.
