Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current single-layer touch screens experience performance degradation and visual effect issues due to high temperature baking processes, which affect the outer frame layer made of white photoresist and ink materials.
Innovation Solution
A touch screen design featuring an inner frame layer made of ink material positioned between the sensing component and the outer frame layer, which acts as a heat insulator, preventing heat transfer and maintaining the stability of the outer frame layer during high temperature processes, while the outer frame layer is formed using stacked ink layers for improved visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high temperature baking process is performed during manufacture of ITO touch-control electrode, then the touch-control effect is achieved, but the outer frame layer made of white photoresist and white ink experiences performance degradation and visual effect deterioration
Solution Approach 1:
The patent introduces an inner frame layer as an intermediary component positioned between the sensing component and the outer frame layer. This inner frame layer acts as a thermal barrier that mediates the heat transfer from the high-temperature baking process, preventing direct thermal exposure to the outer frame layer made of white photoresist and white ink, thereby protecting it from performance degradation while still allowing the baking process to proceed for achieving the touch-control effect
Solution Approach 2:
The patent divides the frame structure into two separate layers: an inner frame layer and an outer frame layer. This segmentation allows each layer to serve distinct functions - the inner frame layer handles thermal protection while the outer frame layer maintains visual appearance and structural integrity, resolving the contradiction between achieving high-temperature processing requirements and protecting temperature-sensitive materials
2Reliability
If high temperature baking process is performed during manufacture of ITO touch-control electrode, then the touch-control effect is achieved, but visual effects of the touch screen are affected due to color changes in ink materials
Solution Approach 1:
The inner frame layer serves as a thermal intermediary that blocks heat from reaching the outer frame layer containing white photoresist and white ink. This protection prevents thermal-induced color changes in the ink materials, thereby maintaining the visual effects and appearance quality of the touch screen while still enabling the high-temperature baking process necessary for achieving the touch-control effect
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inner frame layer effectively insulates the outer frame layer from high temperatures, preventing performance degradation and maintaining visual quality by avoiding color changes in the ink materials, thus enhancing the overall performance and appearance of the touch screen.
Implementation Method 1
the inner frame layer acts as a heat insulator, preventing heat transfer and maintaining the stability of the outer frame layer during high temperature processes

AI summary
The present disclosure discloses a touch screen and a manufacturing method thereof, as well as a touch display apparatus comprising such a touch screen. The touch screen comprises: a substrate; a sensing component arranged on the substrate; an inner frame layer arranged to surround the sensing component; and an outer frame layer formed around an outer periphery of the inner frame layer, for encapsulating the sensing component and the inner frame layer. During the sensing component made of metal material is manufactured, since the inner frame layer is arranged at the inner side of the outer frame layer, the inner frame layer plays a role of heat insulation from a high temperature generated by the inner side of the outer frame layer, and thus prevents heat from being transferred to the outer frame layer. Therefore, even if a high temperature baking process is used, performance degradation of the outer frame layer caused by the high temperature may also be avoided.
