Display Panel UV Curing for Adjacent and Bending Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes for display apparatuses with bendable or foldable display panels are inefficient, as they do not effectively manage the application and curing of materials in the adjacent and bending areas, leading to prolonged manufacturing times.
Innovation Solution
A method and apparatus that applies materials to the adjacent and bending areas of a display panel and simultaneously cures them using specific wavelength bands of light (365 nm to 405 nm) to achieve a curing rate of at least 80% in both areas, utilizing separate curing devices for each area to ensure efficient material application and curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If materials in the adjacent area and bending area are cured sequentially, then each material can be cured thoroughly, but the manufacturing time increases and logistics movement becomes more complex
Solution Approach 1:
The patent combines two separate curing operations into a single simultaneous curing process. The curing device is designed to irradiate both the adjacent area and bending area with UV light at the same time, eliminating the need for sequential curing and reducing manufacturing time while maintaining curing quality through optimized light intensity distribution.
Solution Approach 2:
The patent employs dynamic adjustment of light intensity in different regions. The curing device adjusts the UV light intensity to be higher in the bending area (which requires more energy for thorough curing) and lower in the adjacent area, enabling simultaneous curing of both regions with different curing requirements in a single operation.
2Manufacturing precision
If separate curing devices are used for adjacent area and bending area, then each area receives optimized curing, but device complexity increases
Solution Approach 1:
The patent designs a universal curing device that can simultaneously serve multiple curing functions. A single curing device is configured to irradiate both the adjacent area and bending area with adjustable light intensity, eliminating the need for separate curing devices while maintaining optimized curing quality for each region through dynamic light control.
Solution Approach 2:
The patent changes the light intensity parameter spatially across different regions. The curing device adjusts UV light intensity to be higher in the bending area and lower in the adjacent area, allowing a single device to perform differentiated curing functions that would otherwise require multiple specialized devices.
