Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices, particularly liquid crystal display panels, face challenges in efficiently supporting and aligning components like the display panel, backlight unit, and optical layers, leading to issues with light distribution and overall efficiency.
Innovation Solution
The design incorporates a frame with a depressed portion and guide panels that support the display panel and optical layers, ensuring proper alignment and light distribution through a combination of bent and protruding features, including a light guide plate and reflection sheet, to enhance light efficiency and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a frame with depressed portion and guide panels is used to support the display panel and optical layers, then structural integrity and alignment are improved, but device complexity increases
Solution Approach 1:
The frame integrates multiple functions into a single structure: it provides structural support, guides panel alignment through depressed portions, and positions optical layers. This merging of support, alignment, and positioning functions into one integrated frame structure improves stability while avoiding the need for separate components for each function.
Solution Approach 2:
The frame serves multiple purposes simultaneously: it acts as a structural support element, a alignment guide for the display panel, and a positioning structure for optical layers. This multi-functionality reduces the overall number of components needed while maintaining structural integrity and proper alignment.
2Manufacturing precision
If guide panels with bent portions and flanges are used for alignment, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The guide panels are pre-formed with bent portions and flanges at specific angles and positions before assembly. This preliminary shaping ensures that when components are assembled, the display panel and optical layers are automatically aligned to the correct positions and orientations, achieving high manufacturing precision through pre-positioning rather than complex adjustment during assembly.
3Reliability
If multiple support portions and mounting portions are included in the housing, then reliability is improved, but device complexity increases
Solution Approach 1:
The housing is divided into multiple functional sections: upper end support portions for supporting the display panel, lower end support portions for positioning, and mounting portions for securing components. This segmentation allows each section to perform its specific function optimally, improving overall reliability while organizing complexity into manageable, functionally distinct segments.

AI summary
A display device can include a frame; a reflection sheet disposed on the frame; a housing coupled to at least one side of the frame; a substrate disposed on the housing; a light assembly mounted on the substrate; a light guide plate disposed on the reflection sheet and at a side of the light assembly; a guide panel coupled to another side of the frame; and a display panel disposed on the light guide plate, in which the display panel is disposed on the guide panel and overlaps with the housing.
