Integrated Frame Design for Thin Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display devices with backlight modules require additional components like plastic frames and electronic control boards, increasing thickness and border width, which hinders the achievement of a thin, light, and narrow-frame design.
Innovation Solution
A display device design featuring a frame with supporting portions for both the display panel and backlight module, eliminating the need for additional plastic and side frames, and utilizing a flexible printed circuit to connect the control element without extending it from the panel, thereby reducing border width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional plastic frame and side frame are used to assemble backlight module and display panel, then structural stability is improved, but overall thickness and border width increase
Solution Approach 1:
The frame integrates multiple functions: it serves as both the structural support for assembling the backlight module and display panel, and simultaneously acts as the side frame for exterior support. This merging of functions eliminates the need for separate plastic frame and side frame components, reducing border width while maintaining structural stability.
Solution Approach 2:
The frame is designed as a multi-functional component that provides structural support, acts as an exterior side frame, and enables component assembly without requiring additional dedicated parts. This universal design reduces the overall number of components and minimizes border width.
2Adaptability or versatility
If electronic control board extends from display panel towards side of display, then control functionality is achieved, but plastic frame must extend to support it, increasing border width
Solution Approach 1:
The frame serves dual purposes: it provides structural support and simultaneously acts as the mounting structure for the electronic control board. By integrating the control board support function into the frame itself, the design eliminates the need for the frame to extend additional lengths to support separate control board mounting structures.
3Ease of manufacture
If multiple separate components (back plate, plastic frame, side frame) are used, then assembly flexibility is improved, but number of components increases, hindering thin and light design
Solution Approach 1:
The design merges the back plate, plastic frame, and side frame into an integrated frame structure that provides all necessary support functions. This reduces the component count while maintaining assembly flexibility through the frame's integrated design features.
Solution Approach 2:
The frame is designed as a universal component that performs multiple functions previously requiring separate parts: structural support, side frame function, and component mounting. This multi-functionality reduces device complexity while maintaining ease of manufacture.
