Flat Panel Display Module Non-Overlapping Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional flat panel display modules do not effectively reduce their exterior size due to overlapping bezels and frames, which contribute to increased thickness.
Innovation Solution
A flat panel display module design featuring a frame with tenons and fixing plates, where the upper and lower bezels engage with the frame through tenons and holes, allowing the bezels to be non-overlapping, and a fixing plate is exposed outside to protect the display panel, reducing the overall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the upper and lower bezels are overlapped to cover the planar display panel and frame, then the structural stability is improved, but the thickness of the flat panel display module increases
Solution Approach 1:
The patent applies nesting by placing the frame inside the overlapping region of the upper and lower bezels. The side wall of the frame is positioned within the space between the upper bezel and lower bezel, allowing the frame to be nested within the bezel assembly rather than requiring additional overlapping thickness. This resolves the contradiction by maintaining structural stability through the nested frame-bezel configuration while reducing the overall thickness of the display module.
2Reliability
If the fixing plate is covered by the bezel to protect the planar display panel, then the protection of the display panel is improved, but the thickness of the flat panel display module increases
Solution Approach 1:
The patent extracts the fixing plate from the region that would be covered by the bezel and positions it to extend beyond the bezel's outer surface. The fixing plate is connected to the side wall of the frame and protrudes outward, allowing it to provide protection for the display panel while being exposed outside the bezel assembly. This eliminates the need for additional bezel overlap thickness, thereby reducing the overall module thickness while maintaining protective functionality.
3Strength
If the side wall of the frame and side walls of the bezels are overlapped, then the structural integrity is improved, but the overall size of the flat panel display module increases
Solution Approach 1:
The patent applies nesting by positioning the side wall of the frame within the overlapping region of the upper and lower bezel side walls. The frame's side wall is nested between the upper and lower bezel side walls, allowing all three components to share the same spatial envelope rather than requiring additional overlapping thickness. This maintains structural integrity through the nested configuration while minimizing the overall volume and external dimensions of the display module.

AI summary
A display module includes a planar display panel being a liquid crystal display panel, a frame disposed under the planar display panel, a lower bezel disposed outside the frame, an upper bezel disposed outside the planar display panel, and a back light module disposed inside the frame. The frame includes at least one side wall. The outer surface of the side wall includes a plurality of tenons and a fixing plate is coupled to the side wall. The fixing plate is contacted with a side of the planar display panel. The side wall of the lower bezel includes a first hole corresponding to a first tenon so that the first tenon can be engaged with the first hole. The side wall of the upper bezel includes at least one second hole corresponding to a second tenon so that the second tenon can be engaged with the second hole.
