Display Frame Assembly With Mounting-Ear Avoidance Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The appearance of electronic devices with displays, such as televisions, is not delicate enough due to the wide width of the ground facing-side frame, which affects user experience.
Innovation Solution
The implementation of an avoidance structure that accommodates mounting ears of an optical film, reducing the spacing between the optical film and the frame, and incorporating support structures to minimize the frame's width and ensure proper lapping with the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the ground facing-side frame is made wide to ensure structural support and assembly space, then the frame can accommodate components like the optical film and support members, but the appearance delicacy of the electronic device deteriorates
Solution Approach 1:
The patent utilizes the thickness dimension (Z-direction) to create avoidance spaces that accommodate mounting ears, allowing the frame width (X-direction) to be reduced while maintaining assembly functionality. The folded edge portion of the backplane extends in the thickness direction to provide mounting surfaces without increasing frame width.
Solution Approach 2:
The mounting ears of the optical film are nested within avoidance spaces created by the folded edge portion of the backplane. This nesting arrangement allows the optical film to be mounted within the frame structure without requiring additional frame width, thereby improving appearance delicacy while maintaining assembly capability.
2Shape
If the spacing between the optical film and the frame is reduced to improve appearance, then the frame width decreases and appearance delicacy improves, but the mounting and assembly of the optical film becomes more difficult
Solution Approach 1:
The backplane is pre-formed with a folded edge portion that creates avoidance spaces before the optical film is mounted. This preliminary structuring of the backplane provides pre-defined mounting locations and spaces, making it easier to assemble the optical film with minimal spacing to the frame while maintaining manufacturing ease.
3Shape
If the frame width is reduced to improve appearance delicacy, then the spacing between components is minimized, but the structural support and component accommodation capability deteriorates
Solution Approach 1:
The patent compensates for reduced frame width by utilizing the thickness dimension. The folded edge portion of the backplane extends in the Z-direction to provide structural support surfaces and accommodation spaces, maintaining structural capability without requiring increased frame width in the X-direction.
Solution Approach 2:
The backplane is segmented into a folded edge portion that provides localized support structures. This segmentation allows the backplane to provide adequate structural support within a compact width by distributing support functions across different spatial zones created by the folded structure.

AI summary
This application provides an electronic device. The electronic device includes an optical film, a support member, a backplane, a frame, and at least one avoidance structure. The backplane includes a folded edge portion, the support member includes a first portion, and the optical film includes at least one mounting ear. Along a first direction, the first portion is disposed between the folded edge portion and the frame. Each avoidance structure corresponds to one mounting ear, at least a part of each avoidance structure is disposed on the folded edge portion, and each avoidance structure defines an avoidance space used to accommodate at least a part of the corresponding mounting ear. With the electronic device provided in this application, a width of the frame can be reduced, to improve delicacy of an appearance of the electronic device.
