Film-Wrapped Display for Glass Fragment Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In aircraft displays with flat front surfaces, glass fragments can scatter during impacts due to the lack of effective protection against breakage, posing a safety risk.
Innovation Solution
A film wrapping display design where a protective film is adhered to cover the touch surface and extend around the edges of the glass, preventing glass pieces from scattering parallel to the touch surface by anchoring the film to the housing or support frame, thereby containing the fragments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat front surface design is adopted for the display, then the aesthetic appearance and modern design are improved, but the glass may scatter during impact load
Solution Approach 1:
A film is adhered to the front surface of the display panel and extended to wrap around the side surfaces of the display housing. This film structure contains glass fragments when the glass breaks, preventing scattering while preserving the flat front surface aesthetic design.
2Object-affected harmful factors
If the film is extended to wrap around the side surfaces, then glass scattering is prevented, but the device complexity increases
Solution Approach 1:
The film serves multiple functions: it protects the front surface, wraps around side surfaces to contain glass fragments, and integrates with the display housing structure. This multi-functionality reduces the need for separate protective components, thereby limiting the increase in device complexity.
3Object-affected harmful factors
If the film is adhered to cover the touch surface and extend around edges, then glass fragments are contained, but the manufacturing process becomes more difficult
Solution Approach 1:
The film is pre-cut and pre-formed to match the display panel and housing geometry before assembly. This preliminary preparation simplifies the manufacturing process by reducing complex on-site adjustments and ensuring proper fit during final assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The film wrapping display effectively contains glass fragments, enhancing safety by preventing scattering and maintaining a clean, aesthetically pleasing appearance.
Implementation Method 1
an adhesive member extending from the first surface along the edge of the touch panel to a rear surface of the touch panel, and covering the edge of the touch panel and portions of the front surface, the rear surface, and the side surfaces of the housing

AI summary
A film wrapping display includes a panel that is transparent to light and is configured to display information on one surface of the panel, and a film adhered to cover the one surface of the panel on which the information is displayed. The film is adhered to the other surface of the panel opposite to the one surface in addition to the one surface of the panel. An edge of the film is positioned at the other surface while the film covers an outermost periphery of the panel and extends around to the other surface.
