Thin-Profile Television Backplane and Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin-profile television devices occupy excessive space due to the combined thickness of the rear cover and backlight module, which limits their mounting options when attached to a supporting surface.
Innovation Solution
The design incorporates a backplane, display unit, frame, driving printed circuit board, heat dissipation element, and optical printed circuit board within a shared receiving space, with a convex second front frame portion to accommodate these components, reducing overall thickness and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the rear cover and backlight module are mounted separately on the television, then the functional components are properly supported, but the overall thickness of the television increases
Solution Approach 1:
The patent combines the rear cover and backlight module into a single integrated assembly where the backlight module is mounted directly onto the rear cover, forming a unified structure that reduces the number of separate mounting operations and minimizes overall thickness while maintaining functional integrity
Solution Approach 2:
The backlight module is nested within the depth of the rear cover structure, with the light guide plate and diffuser layer positioned within the available space of the rear cover assembly, effectively utilizing the vertical space to reduce overall television thickness
2Adaptability or versatility
If the rear cover and backlight module occupy large space, then the components are properly housed, but the mounting options on supporting surfaces are limited
Solution Approach 1:
The patent transitions from a traditional deep mounting approach to a thin-profile design by redistributing component arrangements across different spatial dimensions, utilizing the surface area of the rear cover more effectively to accommodate the backlight module in a flattened configuration that enables versatile mounting options including wall mounting and TV stand placement
3Length of moving object
If the television is designed with thin profile, then the space efficiency is improved, but the structural support for components becomes more challenging
Solution Approach 1:
The rear cover is constructed using composite material structure combining rigid support layers with lightweight filling materials, providing sufficient structural strength to support the backlight module and other components while maintaining a thin overall profile that improves space efficiency

AI summary
A thin-profile television includes a backplane, a display unit, a frame, and a driving printed circuit board. The backplane includes a flat first surface. The backplane and the frame, defining a first receiving space, receive the display unit and the driving printed circuit board. The frame includes a first front frame portion and a second front frame portion, the first front frame portion and the second front frame portion faces away from the backplane. The second front frame portion is convex relative to the first front frame portion. The driving printed circuit board is positioned between the backplane and the side frame portion and adjacent to the side frame portion.
