Solution Overview

Problem

Conventional display devices face limitations in thickness and aesthetics due to the use of multiple frames and complex assembly processes, which hinder the achievement of thin and narrow border designs.

Innovation Solution

A display device with an adhesive layer that fixes the display panel and backlight module in place, allowing for simplified manufacturing processes and thinning while enabling narrow border designs, using a first adhesive layer on the display panel and backlight module, and optionally a second adhesive layer between them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple middle frames and screws are used to fix the display panel and backlight module, then the structural stability is improved, but the device thickness increases and the border design becomes complicated

Engineering Contradiction:

Improvestructural stabilityVSAvoiddevice thickness

Core Design Contradiction:

Stability of the object's compositionVSLength of stationary object

Solution Approach 1:

The patent merges multiple separate fixing components (middle frames and screws) into a single integrated adhesive layer. This adhesive layer simultaneously provides structural support and fixation functionality, eliminating the need for separate mechanical fastening elements and thereby reducing overall device thickness while maintaining stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts and removes the middle frames and screws from the assembly structure, replacing them with an adhesive-based fixation system. This extraction eliminates the thickness contribution of mechanical fastening components and simplifies the border design by removing visible frame structures.

Inventive Principle:

Principle #2Taking out (Extraction)

2Stability of the object's composition

If multiple middle frames and screws are used to fix the display panel and backlight module, then the structural stability is improved, but the device complexity increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidassembly complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines multiple assembly steps and components into a single adhesive application process. Instead of separately installing middle frames, positioning components, and securing with screws, the adhesive layer provides all fixation functions in one step, dramatically simplifying the assembly process and reducing the number of parts.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention removes the complex mechanical fastening system (frames and screws) and replaces it with a simple adhesive bonding process. This extraction eliminates the need for precise mechanical alignment, multiple fastening operations, and assembly of numerous small components, thereby reducing device complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

3Stability of the object's composition

If multiple middle frames and screws are used to fix the display panel and backlight module, then the structural stability is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent consolidates multiple expensive mechanical components (precision-machined middle frames, multiple screws, and associated fastening hardware) into a single, lower-cost adhesive material. This merging reduces the bill of materials cost and eliminates the need for expensive precision machining and assembly operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts and eliminates the costly mechanical fastening system, replacing it with an adhesive bonding solution that requires fewer materials and less complex manufacturing processes. This extraction reduces both material costs and manufacturing overhead, making production more economical.

Inventive Principle:

Principle #2Taking out (Extraction)
