Display Protective Sheet Cutout for Easy Removal and Stable Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective sheets with tabs on display devices can deform or detach when contacted by users or external members, leading to inconvenience and reduced adhesion due to air bubbles, especially when the tab protrudes beyond the device edge.
Innovation Solution
A protective sheet with a cutout formed inward from the edge of the display device, allowing easy removal without protrusion, reducing deformation and detachment risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tab is added to the protective sheet to facilitate removal, then ease of operation is improved, but the protective sheet may deform or detach when contacted by users or external members
Solution Approach 1:
The protective sheet is segmented into a main body portion and a separate tab portion. The tab portion is positioned to protrude from the edge of the display device, allowing users to grasp and remove the protective sheet without contacting the main body. This segmentation enables easy removal while maintaining adhesion stability of the main protective function.
Solution Approach 2:
The tab acts as an intermediary element between the user and the protective sheet. Users interact with the tab to remove the protective sheet, rather than directly contacting the main body. This intermediary approach facilitates removal while preventing direct contact that could cause deformation or detachment.
2Ease of operation
If the protective sheet extends beyond the display device edge to provide a tab, then ease of removal is improved, but air bubbles may form and adhesion quality deteriorates
Solution Approach 1:
The protective sheet is divided into a main body that maintains precise alignment with the display device edges and a separate tab portion that protrudes. This segmentation allows the main body to achieve high adhesion quality without extending beyond the device edge, while the tab provides the necessary functionality for easy removal.
Solution Approach 2:
Different portions of the protective sheet have different functional qualities. The main body portion is optimized for adhesion quality and precise positioning, while the tab portion is optimized for user interaction and removal. This local differentiation resolves the contradiction between adhesion precision and ease of removal.

AI summary
A display device (100) includes: a display module (1) that has a flat surface (1A) rectangular in shape and that displays information on a display area (DA) within the flat surface (1A); and a protective sheet (2) affixed to the flat surface (1A). An outer edge of the protective sheet (2) is positioned, as viewed from a direction orthogonal to the flat surface (1A), on an outer edge of the flat surface (1A) or inward of the outer edge of the flat surface (1A). The protective sheet (2) has a cutout (20) having been formed therein by cutting the protective sheet (2) inward from the outer edge of the protective sheet (2) as viewed from the direction orthogonal to the flat surface (1A).
