Light Guide Plate and Optical Diaphragm Engagement for Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face a challenge in maximizing the effective display area due to the occupation of space by the light guide plate and optical diaphragm, which are typically fixed using methods like double-sided adhesive tape or adhesive frames, leading to a reduction in display effectiveness.
Innovation Solution
The proposed display device design includes a backplate with a receiving cavity, a reflector, a light guide plate with body and extension parts, a light source, and an optical diaphragm with body and extension parts. The light guide plate and optical diaphragm extension parts are located in the frame area and engaged with each other, preventing them from occupying the effective display area and ensuring secure fixation without additional structural elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light guide plate and optical diaphragm are fixed using double-sided adhesive tape or adhesive frames, then the components are securely fixed, but the effective display area is reduced due to occupation of the edge area
Solution Approach 1:
The light guide plate and optical diaphragm are divided into body parts and extension parts. The extension parts protrude into the frame area while the body parts remain in the display area, allowing secure engagement in the frame area without occupying display area.
Solution Approach 2:
The fixation mechanism transitions from occupying the same two-dimensional display area to utilizing the third dimension by extending parts into the frame area, thereby resolving the conflict between fixation stability and display area.
2Area of stationary object
If extension parts are used to engage the light guide plate and optical diaphragm in the frame area, then the effective display area is maintained, but the fixation structure becomes more complex
Solution Approach 1:
The extension parts of the light guide plate and optical diaphragm are engaged together in the frame area, merging their fixation functions into a single integrated structure that eliminates the need for separate adhesive tapes or frames.
Solution Approach 2:
The extension parts themselves serve as the fixation mechanism, engaging with each other to secure both components without requiring additional external fixation elements, thereby simplifying the overall structure.
3Reliability
If additional fixation elements like adhesive tapes or frames are used, then the components are securely fixed, but the device becomes heavier and thicker
Solution Approach 1:
The fixation function is extracted from separate adhesive tapes or frames and integrated directly into the light guide plate and optical diaphragm structures themselves through their extension parts, eliminating additional components.
Solution Approach 2:
The extension parts serve multiple functions: they extend the component structure into the frame area, provide engagement surfaces for secure fixation, and maintain the lightweight thin design by avoiding additional materials.
