Solution Overview

Problem

The existing display module designs are hindered by a middle frame that occupies space on the front side, preventing full-screen optimization of the display panel.

Innovation Solution

A bonding member, comprising multiple bonding members, is used to bind the display panel, optical film layer, light guide plate, and backplane together, eliminating the need for a middle frame and allowing for a full-screen display by filling recessed regions and providing a buffering and decorative effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a middle frame is used to mount the display panel, optical component, and backplane together, then the structural stability is improved, but the display area is reduced due to the frame occupying space on the front side

Engineering Contradiction:
Improvestructural stabilityVSAvoiddisplay area
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The patent removes the middle frame component from the display module structure. Instead of using a separate frame to mount components, the display panel itself serves as the mounting substrate, with its peripheral area used for structural support and component attachment. This extraction of the frame eliminates the obstruction to the display area while maintaining structural integrity through alternative mounting arrangements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The display panel is assigned multiple functions: it serves both as the light-emitting display surface and as the structural mounting substrate for the optical component and backplane. The peripheral area of the display panel performs dual roles of providing structural support and enabling component attachment, eliminating the need for a separate middle frame and maximizing the display area.

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

2Strength

If a middle frame is used for mounting components, then the structural support is improved, but the device complexity increases due to additional components

Engineering Contradiction:
Improvestructural supportVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent merges the mounting function into the display panel itself, combining the display function and structural support function into a single component. The display panel's peripheral area is utilized for mounting the optical component and backplane, eliminating the need for a separate middle frame and reducing the overall number of components in the display module.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display panel serves as both the display surface and the structural mounting substrate. By making the display panel multi-functional, the patent eliminates additional components like the middle frame, thereby reducing device complexity while maintaining adequate structural support through the panel's inherent strength and the distribution of mounting points across its peripheral area.

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

3Area of stationary object

If the peripheral area of the display panel is used for mounting, then the full-screen display is achieved, but the mounting strength may be compromised

Engineering Contradiction:
Improvedisplay areaVSAvoidmounting strength
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

The patent divides the mounting function across multiple locations on the display panel's peripheral area. Instead of relying on a single frame structure, separate mounting members are distributed around the periphery to attach different components (optical component, backplane). This segmentation of mounting points distributes the mechanical stress and maintains mounting strength while allowing the display area to extend to the edges of the panel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different mounting characteristics to different regions of the display panel's peripheral area. Specific local regions are reinforced or equipped with mounting members tailored to the requirements of each component being attached. This localized approach to mounting ensures adequate strength at each mounting point while preserving the overall full-screen display area.

Inventive Principle:
Principle #3Local quality

AI summary

A display module includes a display panel, an optical film layer arranged on a side of the display panel, a light guide plate arranged on a side of the optical film layer away from the display panel, a backplane arranged on a side of the light guide plate away from the display panel, and a bonding member. The bonding member bonds together the display panel, the optical film layer, the light guide plate, and the backplane.
