Display Back Board Positioning Element for Three-Dimensional Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning elements in backlight modules are not stably fixed on the back board, leading to potential collision damage to optical materials or films, and the manufacturing process is complex and costly.
Innovation Solution
A display device with a back board and positioning element featuring side plates and sidewalls that define an accommodating space, where the positioning element is engaged with openings and protrusions to secure it in three dimensions, eliminating the need for additional processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surface of the positioning element is roughened and double-sided tape is attached to fix it on the back board, then the positioning element can be fixed, but the manufacturing process becomes complicated and costly
Solution Approach 1:
The positioning element is integrated directly into the back board structure, merging two previously separate components (back board and positioning element) into a single unified structure. This eliminates the need for separate fixation processes such as roughening surfaces and attaching double-sided tape, thereby simplifying the manufacturing process while maintaining reliable fixation.
Solution Approach 2:
The positioning element is pre-formed as an integral part of the back board during the back board manufacturing process itself, rather than being attached separately afterward. This preliminary integration ensures stable fixation from the outset and eliminates subsequent fixation steps, reducing both process complexity and cost.
2Reliability
If the positioning element is attached using conventional methods, then it can be fixed on the back board, but it cannot be stably fixed in three dimensions and may fall off
Solution Approach 1:
By merging the positioning element with the back board into a single integrated structure, the positioning element achieves stable three-dimensional fixation. The integration ensures that the positioning element cannot detach or shift relative to the back board, eliminating the risk of falling off while maintaining ease of operation.
3Ease of manufacture
If the positioning element is not stably fixed, then the manufacturing process is simpler, but the risk of collision damage to optical materials or films increases
Solution Approach 1:
The integration of the positioning element into the back board structure provides stable fixation that prevents collision damage to optical materials or films. This merging approach achieves both manufacturing simplicity (by eliminating separate attachment steps) and harm reduction (by ensuring stable positioning that prevents accidental collisions).
Solution Approach 2:
The positioning element is pre-integrated into the back board structure during manufacturing, ensuring stable fixation is established before any optical materials are installed. This preliminary integration eliminates the risk of collision damage while maintaining manufacturing efficiency.

AI summary
A display device includes a back board, a display assembly, and a positioning element. The back board includes a bottom plate, a first side plate, and a second side plate. The bottom plate, the first side plate, and the second side plate jointly define an accommodating space, and an opening is between the first side plate and the second side plate. The display assembly is located in the accommodating space. The positioning element is fixed on the back board and includes a filling block, a first sidewall, and a second sidewall. The filling block is engaged with the opening. The first sidewall is connected to the filling block and faces toward an inner side surface of the first side plate. The second sidewall is connected to the filling block and faces toward an inner side surface of the second side plate.
