Flat Panel Display With Concave Window Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel displays face challenges in achieving a slim profile while ensuring effective protection and easy alignment/tilt detection of the display device with respect to the window, as well as reinforcing the display's stiffness and impact resistance.
Innovation Solution
A flat panel display design featuring a concave recess in the window with inclined sidewalls, a printed layer to block external light, and resin layers for thickness reduction and structural reinforcement, along with a buffer member and support frame for impact absorption and alignment verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the display device is mounted directly on the window surface, then the structure is simple and easy to manufacture, but the display thickness cannot be reduced and alignment/tilt detection is difficult
Solution Approach 1:
The display device is positioned in a concave recess on the window surface, transitioning from a flat mounting to a three-dimensional recessed configuration. This dimensional change allows the display to be embedded within the window structure, reducing the overall profile thickness while maintaining structural integrity and enabling alignment detection through the recess geometry.
Solution Approach 2:
The display device is nested within the concave recess of the window, with the recess acting as a housing that contains the display. This nesting arrangement reduces the external dimensions of the display assembly while protecting the display device and providing reference surfaces for alignment verification.
2Difficulty of detecting and measuring
If the display device is mounted directly on the window surface, then alignment verification is difficult, but creating a recess structure makes alignment detection easier
Solution Approach 1:
A printed layer is applied to the edge area of the window and the sidewalls of the recess, creating a visual reference that facilitates alignment detection. The printed pattern provides a visible indicator that allows easy verification of whether the display device is properly aligned and positioned within the recess, solving the alignment detection problem through optical enhancement.
3Strength
If the display device is mounted directly on the window surface, then the structure is compact, but stiffness and impact resistance are insufficient
Solution Approach 1:
Resin layers are applied to the edge area of the window and the sidewalls of the recess before mounting the display device. These resin layers act as cushioning elements that absorb and distribute impact forces, providing enhanced protection and stiffness to the display device while being integrated into the recess structure.
Solution Approach 2:
The window structure combines multiple materials including the window material itself, resin layers for reinforcement and cushioning, and a printed layer for alignment indication. This composite construction provides enhanced stiffness and impact resistance compared to a single-material structure, while the various layers work together to solve multiple functional requirements.
