Slim Border Display Module Using Plastic Frame Baffles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display designs with metallic bezels result in overlapping frames, preventing the reduction of display border thickness and aesthetics.
Innovation Solution
A display module design featuring a front frame with position-limiting openings, a back frame with corresponding openings, and a plastic frame with baffle-wall portions and retracted portions, allowing the baffle-wall portions to be exposed and reducing frame thickness by creating an accommodation space for the back-side plates and display unit corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metallic bezel is used to clad the plastic frame and display panel, then the display is protected and firmly assembled, but the border thickness increases and the slim border effect is lost
Solution Approach 1:
The patent removes the metallic bezel component entirely from the display structure. Instead of using a separate metallic cladding layer, the plastic frame itself is designed with integrated positioning structures (baffle portions and retracted portions) that directly secure the display panel, eliminating the need for the metallic bezel and its associated thickness.
Solution Approach 2:
The patent merges the functions of the metallic bezel (protection and assembly firmness) into the plastic frame structure itself. The plastic frame is designed with integrated baffle portions that provide both structural support and positioning functionality, combining multiple roles into a single component rather than requiring separate metallic cladding.
2Stability of the object's composition
If the plastic frame, back frame and front frame overlap and cover each other, then the components are securely assembled, but the border cannot be made slim
Solution Approach 1:
The patent implements a nested arrangement where the display panel is positioned within the plastic frame's baffle portions, which are themselves integrated into the overall frame structure. The baffle portions create nested spaces that hold the display panel corners without requiring overlapping layers of frames, achieving secure assembly through nesting rather than layering.
Solution Approach 2:
The patent transitions from a traditional multi-layer overlapping frame structure to a design where the baffle portions extend in a different spatial dimension (perpendicularly from the frame surface) to secure the display panel. This dimensional change allows the display panel to be firmly positioned without increasing the border thickness in the conventional direction.
3Reliability
If the display panel is firmly assembled to the plastic frame, then the display is stable, but the border thickness increases
Solution Approach 1:
The patent applies local quality by designing baffle portions with specific geometric features (retreated portions) only at the critical locations where display panel corners need to be positioned and secured. Rather than uniformly thickening the entire frame border, the additional structural elements are localized to specific areas, providing firm assembly stability only where needed while maintaining slim borders elsewhere.

AI summary
A display module and a front frame, a back frame and a plastic frame used in the display module are disclosed by the invention. The display module includes a front frame, a back frame, a plastic frame and a display unit. The front frame has a top-plate, a plurality of front-side-plates connecting the top-plate and at least two first position-limiting openings. The back frame has a bottom-plate, a plurality of back-side-plates connecting the bottom-plate and at least two second position-limiting openings. The plastic frame is disposed between the front frame and the back frame and includes a body, at least one side-wall, at least two baffle-wall portions and at least two retracted portions. The first position-limiting openings and the second position-limiting openings expose the baffle-wall portions.
