Solution Overview

Problem

Existing flat display panels, such as liquid crystal display devices, face challenges in enhancing mechanical strength while maintaining lightweight and low power consumption, leading to potential breakage under external stress due to contact with supporting frames.

Innovation Solution

A display device design featuring a plate-like display panel with extending portions supported by a face panel and a frame, where the display panel is spaced apart from the frame using adhesives and elastic elements, preventing direct contact and allowing curvature to absorb stress without breakage, while maintaining a gap for 3D display functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the display panel is directly supported by the frame, then the structural support is improved, but the mechanical strength deteriorates due to stress concentration at contact points

Engineering Contradiction:
Improvestructural supportVSAvoidmechanical strength
Core Design Contradiction:
Stability of the object's compositionVSStrength

Solution Approach 1:

The patent introduces a frame as an intermediary element that does not directly contact the display panel. Instead, the frame supports the face panel, which in turn supports the display panel through extending portions. This intermediary arrangement distributes stress across larger areas and prevents stress concentration at direct contact points, thereby maintaining mechanical strength while providing structural support.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the display panel is made thinner and lighter, then the power consumption is reduced, but the mechanical strength deteriorates leading to potential breakage

Engineering Contradiction:
Improvepower consumptionVSAvoidmechanical strength
Core Design Contradiction:
Use of energy by moving objectVSStrength

Solution Approach 1:

The patent moves the support structure from a two-dimensional direct contact arrangement to a three-dimensional configuration where the frame supports the face panel, which extends to support the display panel. This spatial redistribution creates a more efficient load-bearing structure that can support thinner, lighter display panels without requiring direct contact, thus maintaining strength while enabling reduced power consumption.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Strength

If the display panel is spaced apart from the frame, then the mechanical strength is improved by preventing stress concentration, but the device complexity increases due to additional supporting structures

Engineering Contradiction:
Improvemechanical strengthVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The face panel serves multiple functions: it provides the front surface of the display device, supports the display panel through its extending portions, and acts as a structural element connected to the frame. By making the face panel multi-functional, the patent avoids adding separate support structures that would increase complexity, while still achieving the goal of spacing the display panel from the frame to prevent stress concentration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Stability of the object's composition

If the face panel extends to the outside from the display panel, then the support structure is improved, but the manufacturing precision requirements increase for proper alignment

Engineering Contradiction:
Improvesupport structureVSAvoidalignment precision
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The face panel is designed with extending portions that protrude beyond the display panel boundaries before final assembly. This preliminary extension allows for easier alignment and positioning during manufacturing, as the extending portions can be used as guides or reference features. The extending portions are then integrated with the frame structure, ensuring proper alignment without requiring high-precision direct bonding between the display panel and frame.

Inventive Principle:
Principle #10Preliminary action

AI summary

A display panel includes a first end portion and a second end portion facing each other. A face panel is arranged above the front side of the display panel including a first extending portion and a second extending portion extending to the outside from the first and second end portions of the display panel. An adhesive element is provided on the display panel along its end portions to adhere the display panel to the face panel. A frame is arranged so as to being spaced apart from the display panel having a first supporting portion and a second supporting portion to support the first and second extending portions of the face panel. The first and the second extending portions of the face panel are sandwiched between the bezel and the first and second supporting portions of the frame so that the display panel does not contact with the frame.
