Solution Overview

Problem

Flexible display panels with support components suffer from severe creases, particularly in bending zones, which affect the display effect and user experience.

Innovation Solution

A display module with a bending zone and a non-bending zone, featuring a flexible screen and a support component with a first groove located near the bending zone. The groove reduces the rigidity of the support component, allowing easier bending and reducing stress, thereby alleviating creases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a support component is added to the display panel, then the support and structural integrity is improved, but the crease severity in the bending zone increases

Engineering Contradiction:
Improvesupport component strengthVSAvoidcrease severity
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

The support component is designed with non-uniform thickness, featuring a first groove that creates a thinner region in the bending zone and a thicker region in the non-bending zone. This local variation in thickness allows the support component to have different mechanical properties in different areas, enabling it to provide sufficient support while reducing crease severity in the bending zone.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The thickness parameter of the support component is changed spatially by introducing the first groove. The thickness transitions from a first thickness in the bending zone to a second thickness in the non-bending zone, where the second thickness is greater than the first thickness. This parameter change optimizes the balance between support function and crease mitigation.

Inventive Principle:
Principle #35Parameter changes

2Strength

If the support component rigidity is increased, then the support function is improved, but the bending flexibility and stress distribution deteriorate

Engineering Contradiction:
Improvesupport component rigidityVSAvoidbending flexibility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The support component exhibits local quality variations through the first groove design, creating a thinner, more flexible region in the bending zone and a thicker, more rigid region in the non-bending zone. This allows the component to be rigid where support is needed and flexible where bending occurs.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The support component's mechanical properties are made dynamic through the thickness variation, allowing it to adapt its rigidity based on the operational requirements of different zones - flexible during bending operations and rigid during display operations.

Inventive Principle:
Principle #15Dynamics

AI summary

The present application provides a display module and a display device, the display module includes a bending zone and a non-bending zone which are adjacently arranged; the display module includes a flexible screen and a support component which are laminated, and the support component is located on a backlight side of the flexible screen; the support component is provided with a first groove, and the first groove is located on a side of the bending zone close to the non-bending zone. The first groove may reduce the rigidity of the support component on the side of the bending zone close to the non-bending zone and alleviate the crease in the support component, preventing the crease of this part of the support component from being too sharp and thus alleviating the crease of the display module.
