Display Device Planar Back Housing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in reducing overall thickness and production costs due to the separation of the device housing and module back panel, which limits the placement of components like the circuit board.
Innovation Solution
The integration of a planar back housing that serves as both the display module's back housing and the device's outer housing, combined with a frame structure featuring protrusions and a positioning elastic sheet, allows for a direct-type backlight and internal component arrangement that reduces thickness and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the device housing and module back panel are separated, then the structural integrity and support are improved, but the overall thickness and production cost cannot be reduced
Solution Approach 1:
The patent integrates the device housing and module back panel into a unified structure. The housing body serves dual functions as both the outer housing and the module back panel, eliminating the need for separate components. This merging approach reduces the overall thickness while maintaining structural integrity and support functions.
2Length of moving object
If the back housing is integrated with the outer housing, then the thickness and cost are reduced, but the placement of internal components like circuit board becomes more constrained
Solution Approach 1:
The housing is divided into functional zones with protrusions creating distinct placement areas. The first protrusion provides a dedicated mounting region for the circuit board, while the second protrusion accommodates the display module. This segmentation allows efficient component placement within the integrated housing structure without compromising thickness reduction.
Solution Approach 2:
The patent utilizes the thickness dimension to create stepped portions on the protrusions, forming multi-level placement surfaces. This dimensional approach allows multiple components to be arranged at different heights within the integrated housing, providing component placement flexibility while maintaining a thin overall profile.
3Ease of manufacture
If conventional separate housing and back panel structure is used, then component placement is flexible, but production cost and thickness reduction are limited
Solution Approach 1:
By merging the housing and back panel into a single integrated component, the patent reduces the number of parts that need to be manufactured and assembled. This consolidation simplifies the manufacturing process, reduces production costs, and simultaneously achieves thickness reduction by eliminating the interface and spacing between separate components.

AI summary
A display device includes: a frame, including a frame body, a first protrusion disposed on the frame body, and a second protrusion disposed on the frame body, the second protrusion including at least one stepped portion; a display panel, located on a side of one stepped portion of the at least one stepped portion close to a light emitting surface of the display device and located on an inner side of the frame body; and a planar back housing, fixed on the inner side of the frame body and a side of the first protrusion away from the light emitting surface.
