Integrated Frame Touch Display Module Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch display modules are heavy and thick due to their structural components, including a backlight module with an iron shell and a cover glass, which complicates assembly and increases weight and thickness.
Innovation Solution
A touch display module design that integrates a backlight module, thin film transistor substrate, color filter, and polarizer within a single mechanical component using an integrated frame, eliminating the need for an iron shell and cover glass, with the polarizer serving as the outer surface and being hardened for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a backlight module with an iron shell and a cover glass are used, then the structural strength and protection are improved, but the overall weight and thickness of the touch display module increase
Solution Approach 1:
The patent removes the iron shell from the backlight module and the cover glass from the display structure, extracting these heavy components that were providing structural strength. The backlight module is redesigned without the iron shell, and the display layer is directly exposed without a separate cover glass, thereby reducing overall weight while maintaining necessary protection through alternative means.
Solution Approach 2:
The patent merges multiple previously separate components into an integrated structure. The backlight module, display layers, and frame are combined into a more unified assembly, eliminating the need for separate protective elements like the iron shell and cover glass, thus reducing weight while maintaining structural integrity.
2Strength
If a backlight module with an iron shell and a cover glass are used, then the structural strength and protection are improved, but the overall thickness of the touch display module increases
Solution Approach 1:
The patent removes the iron shell from the backlight module and the cover glass from the display structure, extracting these thick components that were providing structural strength. This extraction directly reduces the overall thickness of the touch display module while maintaining necessary protection through the integrated frame structure.
Solution Approach 2:
The patent merges the backlight module, display layers, and frame into a more integrated assembly, eliminating the need for separate protective elements like the iron shell and cover glass. This merging reduces the cumulative thickness of multiple separate components while maintaining structural integrity through the unified design.
3Stability of the object's composition
If multiple separate components (backlight module, cover glass, etc.) are used, then the structural integrity is maintained, but the assembly process becomes more complex
Solution Approach 1:
The patent merges the backlight module, display layers (including thin film transistor substrate, color filter, and polarizer), and frame into a more integrated assembly. This reduces the number of separate components that need to be assembled, thereby simplifying the assembly process while maintaining structural integrity through the unified design.
Solution Approach 2:
The integrated frame structure serves multiple functions simultaneously: it provides structural support, houses the backlight module, and supports the display layers. This multi-functionality reduces the need for separate dedicated components, simplifying the overall assembly while maintaining structural integrity.

AI summary
A touch display module has plural sensors and includes an integrated frame, a backlight module, a thin film transistor substrate, a color filter, and a polarizer. The integrated frame has a bottom plate portion and a side plate portion, and the side plate portion stands on the bottom plate portion. The backlight module is disposed on the bottom plate portion. The thin film transistor substrate is disposed on the backlight module. The color filter is disposed on the thin film transistor substrate. The polarizer is disposed on the color filter. One surface of the polarizer is an outer surface of the touch display module. The thin film transistor substrate and/or the color filter is connected to the side plate portion of the integrated frame. Therefore, by using the integrated frame to integrate required components into one mechanical part, the touch display module has thinner thickness and lighter weight.
