Segmented Back Plate for Display Buffering and Expansion
Solution Overview
Problem
Conventional backlight modules, particularly those with solid mold frames, suffer from limited buffering against external forces and restricted expansion of light guide plates, leading to potential damage and abnormal displays due to their rigid structure, which also incurs high production costs.
Innovation Solution
A back plate design featuring a base plate with connecting and support plates that provide a buffer space, allowing for movement and expansion of the light guide plate, eliminating the need for a solid mold frame and reducing assembly complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a solid mold frame is used to fix components, then structural stability is improved, but the light guide plate expansion is restricted and production costs increase
Solution Approach 1:
The back plate is divided into a base plate and multiple support plates connected by connecting plates, creating a segmented structure that allows the light guide plate to expand while maintaining overall structural stability. The support plates are positioned at different locations to provide distributed support rather than a continuous rigid frame.
Solution Approach 2:
The connecting plates allow the support plates to move relative to the base plate, creating a dynamic structure that can adapt to light guide plate expansion. The connection enables controlled movement and buffering, transforming the rigid static structure into a flexible dynamic system.
2Stability of the object's composition
If a solid mold frame is used to fix components, then structural stability is improved, but device complexity and production costs increase
Solution Approach 1:
The back plate is segmented into modular components (base plate, support plates, connecting plates) that can be manufactured separately and assembled, reducing overall complexity while maintaining stability through distributed support points rather than a single complex frame structure.
Solution Approach 2:
The support plates serve multiple functions: providing structural support, allowing light guide plate expansion, and buffering external forces. This multi-functionality reduces the need for additional specialized components, simplifying the overall device structure.
3Strength
If a solid mold frame is used, then component fixation is improved, but buffering against external forces is limited
Solution Approach 1:
The connecting plates enable the support plates to move dynamically in response to external forces, providing buffering capability while maintaining component fixation. The dynamic connection allows controlled movement to absorb shocks and forces.
Solution Approach 2:
The support plates are positioned and connected to create a buffering structure that anticipates and absorbs external forces before they can cause damage to the display panel or other components.
4Strength
If a solid mold frame is used, then structural rigidity is improved, but light guide plate expansion is restricted leading to abnormal displays
Solution Approach 1:
The segmented back plate structure with discrete support plates allows the light guide plate to expand between the support points without restriction, preventing display abnormalities while maintaining sufficient structural rigidity through the distributed support system.
Solution Approach 2:
The support plates provide localized support at specific positions while leaving other areas free for light guide plate expansion. This local quality approach maintains rigidity where needed while allowing expansion where required for display quality.

AI summary
A back plate includes a base plate, a plurality of connecting plates and a plurality of support plates. The base plate has a first surface. The plurality of connecting plates are fixed to at least two edges of the base plate, and each connecting plate extends along a direction substantially perpendicular to the first surface. Each support plate is fixed to an end of a respective one of the plurality of connecting plates away from the base plate, and is substantially parallel to the first surface.
