Solution Overview

Problem

Organic light emitting diode (OLED) displays are prone to damage due to direct impact, as there is no structure between the display panel and the bezel to absorb or distribute sudden loads, leading to deformation and damage during drops or similar incidents.

Innovation Solution

Incorporating a reinforcing member made of materials like stainless steel, steel plate cold commercial, aluminum, or aluminum alloy between the pad area of the display panel and the bezel, which is enclosed by cushioning tape and side wall portions, to absorb and distribute impact forces, thereby enhancing the structural integrity and reducing deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If no structure is placed between the display panel and the bezel to maintain simplicity, then device complexity is reduced, but impact resistance deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidimpact resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

A reinforcing member is introduced as an intermediary component between the display panel and the bezel. This member absorbs and distributes impact forces, preventing direct transmission to the display panel while maintaining overall structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The reinforcing member is pre-installed in the bezel structure to provide cushioning and force distribution before impact occurs. This preliminary protective measure ensures the display panel is protected during drop or impact events without adding complex active protection systems.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If a reinforcing member is added between the pad area and the bezel to improve impact resistance, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveimpact resistanceVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The reinforcing member is strategically positioned only in the pad area where the bezel structure is naturally weaker and most vulnerable to impact. This localized reinforcement provides maximum protection where needed while minimizing overall structural complexity and material usage.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The reinforcing member is constructed from composite materials or metal alloys that provide high strength and impact resistance in a thin profile. This allows the component to deliver superior mechanical protection while maintaining a compact design that does not significantly increase overall device complexity.

Inventive Principle:
Principle #40Composite materials

3Strength

If the reinforcing member is made of strong materials like stainless steel or aluminum alloy to enhance strength, then twisting and bending strength are improved, but weight increases

Engineering Contradiction:
Improvetwisting and bending strengthVSAvoidbezel weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The reinforcing member utilizes advanced metal alloys and composite materials that deliver exceptional strength-to-weight ratios. These materials provide the necessary twisting and bending resistance while keeping the added weight minimal compared to traditional solid metal constructions.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The reinforcing member is designed as a thin-walled or lattice-like structure that maintains high structural strength while minimizing material volume and weight. This geometric optimization allows the component to resist impact forces effectively without adding significant mass to the device.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

An organic light emitting diode (OLED) display is disclosed. In one embodiment, the display includes 1) a display panel including i) a display area configured to display an image and ii) a pad area adjacent to the display area and configured not to display an image, 2) a bezel configured to receive the display panel and 3) a reinforcing member positioned between the pad area of the display panel and the bezel. According to at least one embodiment, the deformation of the portion corresponding to the pad area of the display panel among the bezel may be prevented during an external impact, and thereby the twisting strength and the bending strength may be improved.
