Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional display apparatuses have increased thickness due to the need for a frame and front bezel to fix the display panel, which does not align with the trend of thinning display technology.

Innovation Solution

A panel fixing device with a first limiting unit covering the front surface and a second limiting unit clamping the display panel from the rear, eliminating the need for a frame and front bezel, while using light-transmitting and light-shading materials to reduce light leakage and enhance fixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a frame and front bezel are used to fix the display panel, then the display panel is securely fixed, but the thickness of the display apparatus increases

Engineering Contradiction:

Improvefixing reliabilityVSAvoidthickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent removes the frame and front bezel from the conventional structure, extracting only the essential fixing function. The display panel is directly fixed to the back plate using a simplified fixing structure that eliminates unnecessary components, thereby reducing thickness while maintaining fixing reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a thin film or flexible fixing structure instead of rigid frame and bezel components. This allows the fixing mechanism to maintain structural integrity while minimizing thickness, as the thin film structure provides sufficient support without the bulk of traditional framing.

Inventive Principle:

Principle #30Flexible shells and thin films

2Strength

If the front bezel covers the outer side of the peripheral wall, then the display panel is protected, but the overall thickness increases

Engineering Contradiction:

ImproveprotectionVSAvoidthickness

Core Design Contradiction:

StrengthVSLength of stationary object

Solution Approach 1:

The patent extracts the protective function from the front bezel and integrates it into the back plate structure or eliminates the need for separate protective components. The back plate itself is designed to provide protection, removing the thickness contribution of the front bezel while maintaining protective strength.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the protective function with the back plate structure, combining multiple functions into a single component. The back plate simultaneously provides structural support, protection, and mounting functions, eliminating the need for separate front bezel components and reducing overall thickness.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A display apparatus includes a back plate having a rear wall and a peripheral wall that cooperatively define an accommodation space, a light guide plate disposed in the accommodation space, a display panel disposed in the accommodation space forwardly of the light guide plate, a plurality of stacked optical films disposed between the light guide plate and the display panel, and a panel fixing device including a first limiting unit and a second limiting unit that cooperate with each other to clamp and fix a peripheral edge portion of the display panel therebetween.
