Stereoscopic Display Device Thickness Reduction via Optical Panel Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display devices have a thick profile and a degraded aesthetic appearance due to the front set cover and step height between the front surface of the 3D optical panel and the display device, which compromises their slimness and visual appeal.
Innovation Solution
A stereoscopic image display device design where the 3D optical panel is supported by a panel support member with an adhesive, allowing the upper surface of the 3D optical panel to be exposed, thus eliminating the need for a front set cover and reducing the device's thickness, while enhancing its aesthetic appearance by removing the bezel and step height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a front set cover is used to surround the 3D optical panel, then the structural integrity and protection are improved, but the device thickness increases and aesthetic appearance deteriorates
Solution Approach 1:
The patent removes the front set cover from the display device structure, extracting the protective function to the side and rear portions only. This allows the front surface to be thin and aesthetic while maintaining structural integrity through alternative support structures positioned at the edges and back of the device.
Solution Approach 2:
The protective structure is relocated from the front surface (2D plane) to the side and rear dimensions (3D space). The side and rear portions extend laterally to provide protection without adding front surface thickness, changing the spatial arrangement from front-facing to edge-facing protection.
2Strength
If a front set cover is used to surround the 3D optical panel, then the structural integrity is improved, but the aesthetic appearance deteriorates due to step height
Solution Approach 1:
The front set cover is extracted from the structure, removing the source of step height and visual discontinuity. The protective function is retained through side and rear portions that do not create front surface irregularities, preserving the aesthetic appearance while maintaining structural integrity.
3Reliability
If the 3D optical panel is fully enclosed, then protection and structural support are improved, but device thickness and complexity increase
Solution Approach 1:
The enclosure is extracted from a fully enclosed structure to a partially enclosed structure. The front opening removes unnecessary complexity while side and rear portions maintain protective functions. This selective enclosure reduces structural complexity without compromising essential protection.
Solution Approach 2:
Protection is applied locally rather than uniformly across the entire device. The side and rear portions provide protection where structurally necessary, while the front surface remains exposed for aesthetic purposes. This localized approach reduces overall structural complexity while maintaining adequate protection.

Function Achieved in This Case
The design minimizes the thickness of the stereoscopic image display device and improves its aesthetic appeal by exposing the side and top surfaces of the 3D optical panel, resulting in a more streamlined and visually appealing device.

AI summary
Disclosed is a stereoscopic image display device which has a thin thickness and an enhanced aesthetic appearance. The stereoscopic image display device includes an image display panel, a 3D optical panel, and a panel support member. The image display panel temporally or spatially divides and displays a left-eye image and a right-eye image. The 3D optical panel is coupled to the image display panel, and divides the left-eye image and the right-eye image. The panel support member is coupled to the image display panel with an adhesive member to surround the image display panel. The 3D optical panel is supported by the panel support member such that the upper surface and the side surface of the 3D optical panel are exposed to the outside of the stereoscopic image display device.
