Mask Layer Escape Ditch Bubble Discharge Touch Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panels face issues with bubble entrapment at the boundaries between the sensing and peripheral areas due to the thickness of the mask layer, affecting the appearance and light transmittance of the product.
Innovation Solution
Incorporating escape ditches in the mask layers allows for the discharge of bubbles produced during the adhesive coating process, improving the appearance and light transmittance by enabling their removal from the visible area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mask layer is made thicker to improve appearance and shading, then the shading effect is improved, but bubbles are blocked and cannot be discharged from the sensing area
Solution Approach 1:
The mask layer is segmented by forming escape ditches that divide the continuous mask layer into sections, creating pathways for bubble discharge while maintaining the overall mask structure for shading and appearance
Solution Approach 2:
Escape ditches are extracted from the mask layer structure, removing material to form channels that allow bubbles to be taken out from the sensing area without compromising the mask layer's shading function
2Ease of manufacture
If the mask layer thickness is increased to enhance shading, then non-transparent wire shielding is improved, but light transmittance in the visible area is reduced due to bubble entrapment
Solution Approach 1:
The mask layer is segmented via escape ditches to allow bubble discharge, preventing bubble-related light transmittance issues while maintaining adequate thickness for shading in the non-visible area
Solution Approach 2:
The mask layer has different properties in different areas: it is thick in the non-visible area for shading, and contains escape ditches in specific locations to enable bubble discharge, creating local quality variations that satisfy different functional requirements

AI summary
An embodiment of the present disclosure provides an electronic panel. The electronic panel comprises a protection cover having a visible area and a non-visible area, and a plurality of mask layers sequentially disposed on the non-visible area of the protection cover, wherein at least one of the mask layers has at least an escape ditch. Bubbles produced during the coating process can be discharged from the escape ditch, thereby improving the product's appearance and light transmittance. In addition, the present disclosure further provides a method of manufacturing the electronic panel and an electronic device.
