Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display assemblies have a wide bezel width due to the non-active region being disposed on the front surface, and the ACF bonding is prone to destruction during maintenance.

Innovation Solution

The display assembly features a flexible display body with an extended portion that wraps around a plate, hiding the connecting portion on the rear surface, and uses a folded portion to secure the wire connection on the plate's side, avoiding the front surface and protecting the connection from damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the non-active region is disposed on the front surface of the display assembly, then the display body can be connected to the control board using a flexible board, but the width of the bezel member increases

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The connecting portion is moved from the front surface (2D plane) to the rear surface (another dimension), allowing the non-active region to be utilized without increasing the front bezel width. The flexible board is routed through the end surface of the plate, transitioning the connection path to a different spatial dimension.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The display body is divided into a front surface portion and a rear surface portion (extended portion). The non-active region is segmented and extended to the rear surface, where the connecting portion is disposed, separating the connection function from the front surface appearance.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the ACF bonding is disposed on the front surface of the display, then the flexible board can be connected to the display body, but the ACF bonding is destroyed when the bezel member is peeled off during maintenance

Engineering Contradiction:

Improveease of manufactureVSAvoidconnection reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The connecting portion (ACF bonding) is extracted from the front surface and relocated to the rear surface of the display body. This extraction protects the connection from being damaged during bezel member removal, as the connecting portion is now spatially separated from the front surface assembly process.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The extended portion of the display body acts as an intermediary, providing a rear surface location for the connecting portion. This intermediary structure allows the flexible board to connect to the display body without the connection being exposed on the front surface where it would be damaged during maintenance.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A display assembly includes: a display body that is formed in a flexible sheet shape, and includes an active region and a non-active region; a plate that is disposed on a side of a rear surface of the display body, and supports the display body on a first surface; a control board that performs display control of the display body; and a wire that connects the display body and the control board. The display body has an extended portion that extends a part of the non-active region, and a folded portion that is provided in a middle of the extended portion and folded back so as to wrap around an end surface of the plate.
