Touch Display Apparatus Using Protective Layer as Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional touch electrophoretic display apparatuses are limited by the thickness and weight of the glass substrates used in the touch sensing modules, which hinder the miniaturization of these devices.
Innovation Solution
The touch sensing layer is disposed on a protective layer instead of a glass substrate, reducing the overall thickness and weight by omitting the traditional glass substrate, and using materials like PMMA, PC, or PET for the protective layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a glass substrate is used as the carrier for the touch sensing layer, then the structural strength and stability are improved, but the thickness and weight of the display apparatus increase
Solution Approach 1:
The patent replaces the traditional glass substrate with a flexible thin film substrate that serves as the carrier for the touch sensing layer. This thin film substrate maintains the necessary structural strength while significantly reducing the thickness and weight of the overall display apparatus, enabling miniaturization without compromising the functionality of the touch sensing module
Solution Approach 2:
The patent extracts and removes the glass substrate component from the traditional display structure. By eliminating this thick and heavy component while retaining the essential carrier function through an alternative thin film substrate, the invention achieves thickness reduction and weight loss without sacrificing the structural support needed for the touch sensing layer
2Stability of the object's composition
If a glass substrate is used as the carrier for the touch sensing layer, then the structural stability is improved, but the weight of the display apparatus increases
Solution Approach 1:
The patent employs a flexible thin film substrate instead of glass, which dramatically reduces the weight of the display apparatus. The thin film material is engineered to provide sufficient structural stability to support the touch sensing layer and maintain the integrity of the display structure during operation and handling
Solution Approach 2:
By extracting and removing the heavy glass substrate from the display structure, the patent eliminates the primary source of weight. The alternative thin film substrate provides the necessary structural stability at a fraction of the weight, enabling portable and lightweight display devices
