Transparent Display Frame Segmentation for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses without a backlight assembly face stability issues due to the lack of structural support, and incorporating a light guiding plate with high transparency complicates maintaining both transparency and structural stability.
Innovation Solution
A display apparatus design featuring a display panel, a first covering part, an upper frame, and a lower frame, where the upper frame is attached under the covering part, and the lower frame includes a first and second lower frame portion to support the display panel, enhancing stability and transparency without the need for a backlight assembly, and allowing for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the backlight assembly is omitted to improve transparency, then the structural stability of the display apparatus deteriorates
Solution Approach 1:
The frame structure is divided into multiple segments (first frame, second frame, third frame) that can be independently positioned and combined. The first frame supports the display panel, the second frame provides additional structural reinforcement, and the third frame offers further stability, collectively compensating for the removed backlight assembly while maintaining transparency.
Solution Approach 2:
The patent transitions from a two-dimensional planar support structure to a three-dimensional multi-level frame configuration. By stacking frames at different heights and positions (first frame at display panel level, second frame providing intermediate support, third frame at lower level), the structure gains volumetric stability without blocking the transparent viewing area.
2Illumination intensity
If a light guiding plate with high transparency is used to improve transparency, then maintaining both transparency and structural stability becomes difficult
Solution Approach 1:
The patent extracts and removes the light guiding plate component entirely, replacing its light-guiding function with a different approach (edge-lit or back-lit LED configuration without a separate light guiding plate). This elimination simplifies the overall structure by removing the complex interface between the light guiding plate and frame, reducing the number of parts while maintaining transparency and stability.
3Ease of manufacture
If the frame structure is simplified to improve ease of manufacture, then the structural stability deteriorates
Solution Approach 1:
The frame is segmented into multiple independent components (first frame, second frame, third frame) that can be manufactured separately using standard processes and then assembled together. This segmentation allows each component to be optimized for ease of manufacture while the collective assembly provides the necessary structural stability, resolving the contradiction between simple manufacturing and stable structure.

AI summary
A display apparatus includes a display panel, a first covering part, an upper frame and a lower frame. The first covering part is disposed on the display panel. The upper frame is disposed under the first covering part and includes a first combining portion. The lower frame is combined with the upper frame through the first combining portion, and overlaps a peripheral portion of the display panel.
