Systematic Back Plate with Bending Part for Display Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, such as laptop computers, face challenges in minimizing material cost and thickness due to the use of clamping devices for securing the backlight module, which increases the number of parts and thickness.
Innovation Solution
A display device design featuring a systematic back plate with a bending part that forms a clamping space to securely hold the backlight module, reducing the need for additional clamping devices and materials, and utilizing a second plate made of a different material to enhance support and reduce thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping devices are used to fix the backlight module, then the backlight module is securely fixed, but the number of parts increases and the thickness of the display device increases
Solution Approach 1:
The patent merges the clamping function into the frame structure itself. The frame includes bending parts that extend toward the center to form clamping spaces, eliminating the need for separate clamping devices. This integration reduces the number of parts while maintaining secure fixation of the backlight module.
Solution Approach 2:
The frame serves multiple functions: it provides structural support, forms clamping spaces to secure the backlight module, and eliminates the need for separate clamping devices. This multi-functionality reduces overall device complexity while maintaining reliability.
2Reliability
If clamping devices and frames are used to secure the backlight module, then the backlight module is fixed, but the thickness of the display device increases
Solution Approach 1:
The clamping function is merged into the frame structure through bending parts that form clamping spaces. This eliminates the need for additional clamping devices and their associated frames, thereby reducing the overall thickness of the display device while maintaining secure fixation.
Solution Approach 2:
The frame utilizes bending parts that extend in a curved manner to form clamping spaces, effectively using the vertical dimension to create clamping action without increasing the horizontal thickness of the device.
3Reliability
If clamping devices are used to fix the backlight module, then the backlight module is securely held, but the material cost increases
Solution Approach 1:
The frame structure is designed to include integrated bending parts that form clamping spaces, merging the support and clamping functions into a single component. This eliminates the need for separate clamping devices, reducing material usage and overall cost while maintaining secure fixation.
Solution Approach 2:
The frame serves as both the structural support and the clamping mechanism, eliminating the need for additional clamping devices. This multi-functionality reduces the total amount of material required and lowers manufacturing costs.

AI summary
A display device includes a systematic back plate, a backlight module, and a display panel. The systematic back plate includes a first plate and a second plate. The first plate includes a supporting face and a first side, wherein the first side extends to form a bending part. The bending part bends back with respect to the supporting face and extends toward the center of the supporting face, wherein the bending part forms a clamping space with the supporting face. The first plate and the second plate are made of different materials. The second plate includes a connecting end connecting to the boundary of the first side and the bending part. The backlight module is disposed on the supporting face and supported by the supporting face. At least a portion of the backlight module is received in the clamping space. The display panel is disposed above the backlight module.
