Display Window Blocking Structure for Impact Force Redirection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Display devices are vulnerable to external impacts, which can damage the display panel and other components due to the direct transfer of forces through the window.

Innovation Solution

Incorporating a blocking part with higher hardness than the molding part beneath the window, which redirects external impacts away from the display module, and a molding part to cover the blocking part, enhancing the structural integrity and protection of the display device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a window is attached to the display panel through lamination to protect the display panel, then the display panel is protected from external impact, but the force of external impact is directly transferred through the window to the display panel, causing damage

Engineering Contradiction:

Improveprotection of display panelVSAvoidforce transfer from external impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A blocking part is introduced as an intermediary component between the window and the display panel. This blocking part intercepts and redirects the force from external impacts before the force can be directly transferred to the display panel, thereby resolving the contradiction between providing protection and preventing harmful force transfer

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective structure is segmented into multiple functional components: the window, the blocking part, and the display panel. This segmentation allows each component to perform its specific function - the window provides initial protection, the blocking part redirects impact forces, and the display panel displays images - while reducing direct force transfer between them

Inventive Principle:

Principle #1Segmentation

2Reliability

If a blocking part with higher hardness than the molding part is disposed below the window to redirect external impacts, then the display module is protected from impact damage, but the device complexity increases

Engineering Contradiction:

Improveprotection from impact damageVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The blocking part and molding part are merged into an integrated protective structure. The blocking part is disposed within or alongside the molding part, combining their functions into a unified component assembly that reduces overall device complexity while maintaining impact protection capabilities

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The protective structure uses composite material arrangement with the blocking part having higher hardness than the molding part. This composite structure allows the harder blocking part to redirect impacts while the softer molding part provides cushioning and structural support, achieving protection without excessive complexity

Inventive Principle:

Principle #40Composite materials

AI summary

A display device includes a display module, a window disposed on the display module and including a transmission region and a bezel region disposed proximate to the transmission region, a blocking part disposed below the window and overlapping the bezel region, and a molding part disposed below the window and covering the blocking part. A hardness of the blocking part is greater than a hardness of the molding part.
