Flat Panel Display Monolithic Frame With Concave Circuit Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel displays require additional frame size at the light source side to accommodate the control circuit board, limiting further reduction in frame width and increasing material and transportation costs.
Innovation Solution
A monolithic frame structure with a concave section to house the control circuit board, using flexible connecting wiring to reroute the board to the underside of the frame, and a cushion between the backlight unit and cell, allowing for a thinner frame design and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the control circuit board is configured outside the light source side of the bottom cover, then the control circuit board can be accommodated, but the frame width at the light source side increases
Solution Approach 1:
The control circuit board is nested within the bottom cover's housing space, specifically utilizing the internal volume of the bottom cover rather than external space. This nesting approach allows the control circuit board to be accommodated without increasing the overall frame width, as the board is housed within the existing structural envelope of the bottom cover.
Solution Approach 2:
The control circuit board is repositioned from a traditional external configuration to an internal configuration within the bottom cover's housing. This dimensional reorganization utilizes the Z-axis (depth) of the bottom cover rather than expanding the X-Y plane (frame width), thereby reducing the frame width while maintaining functionality.
2Area of stationary object
If additional space is required to accommodate the control circuit board, then the control circuit board can be installed, but the frame width at the light source side increases
Solution Approach 1:
The bottom cover is designed to integrate multiple functions: it serves as both the protective housing and the mounting structure for the control circuit board. By merging the housing function and the circuit board mounting function into a single component, the design eliminates the need for separate mounting structures that would increase frame width, while the integrated design simplifies the assembly process.
3Reliability
If the frame structure is used to protect the backlight module and components, then the components are protected, but the frame width increases
Solution Approach 1:
The bottom cover is designed as a multi-functional component that simultaneously provides protective housing for the panel module and serves as the mounting structure for the control circuit board. This universal design eliminates the need for separate protective frames and mounting structures, thereby reducing the overall frame width while maintaining component protection and circuit board installation capabilities.

AI summary
In a flat panel display having integral frame structure, features of a metal frame and a plastic support, which support, position, and fix each component, are incorporated as an integral frame structure, such that no additional structure component is needed for the flat panel display to assemble the backlight module and the panel module. The frame structure is assembled to the bottom cover via screw that can reduce defectiveness of repetitive processing. A concave section at the bottom of the frame structure can contain a control circuit board for the panel cell such that the control circuit board can be rerouted downward to the bottom of the frame structure. The space required at the light source side of the flat panel display can be reduced, hence leading to the flat panel display with thin frame at the light source side.
