Solution Overview

Problem

Existing display devices face challenges in confirming the authenticity and engraved patterns of components such as windows, touch screens, and displays that are freely attached and detached from different channels, leading to potential authenticity issues and manufacturing complexities.

Innovation Solution

A display device with an adhesion reduction layer featuring a micro protrusion pattern is introduced, allowing for the confirmation of authenticity and engraved patterns by forming a pattern of micro protrusions on the adhesion reduction layer, facilitating easy attachment and detachment while maintaining clarity and transparency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If components (window, touch screen, display) are freely attached and detached from different channels, then ease of repair and adaptability are improved, but authenticity confirmation becomes difficult

Engineering Contradiction:
Improveease of replacementVSAvoidauthenticity confirmation
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The patent applies visual pattern recognition through micro protrusions on the adhesion reduction layer. These patterns create specific light reflection and refraction characteristics that serve as authenticity markers. When viewed under appropriate lighting conditions, the micro protrusion patterns produce distinctive visual effects that confirm the genuine identity of components, thereby maintaining reliability while allowing free attachment and detachment from different channels.

2Ease of operation

If adhesion reduction layer is applied to facilitate detachment, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveease of detachmentVSAvoidpattern formation precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent modifies the physical parameters of the adhesion reduction layer by introducing micro protrusions with specific geometric characteristics. These micro structures change the surface topology and adhesion properties, enabling easy detachment while the patterns serve as authenticity markers. The micro protrusion dimensions and arrangements are controlled within specific parameter ranges to achieve both operational ease and manufacturing feasibility.

AI summary

Suggested is a display device including an adhesion reduction layer having a micro protrusion pattern capable of identification of the authenticity of at least one product from among a window, a touch screen and a display, which are freely detachable and are obtained via different channels, and a pattern engraved thereon. The display device consists of a window, a display, and optionally a touch screen, and comprises an adhesion reduction layer having a micro protrusion pattern, wherein the device and method comprise: a detachable layer which is positioned on at least one from among the window, the touch screen and the display and has an adhesive force of 0.1gf/25mm to 500gf/25mm; and a pattern made by a micro protrusion formed on a part of the adhesion reduction layer which is positioned on any one from among the window, the touch screen and the display so as to face the detachable layer and reduces the adhesive force of the detachable layer.
