Bezel Protrusions Prevent Display Ripple in LCD Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display modules in portable electronic devices suffer from display abnormalities like 'ripple' due to torsional forces applied by screws, which deform the bezel and affect display quality, and existing solutions that attempt to mitigate this issue compromise structural strength or fail to completely prevent abnormalities.
Innovation Solution
A housing structure for liquid crystal display modules featuring a bezel with protruding portions on its side sections that minimize deformation by maintaining a distance from the display module's surface, preventing torsional forces from causing pressure on the liquid crystal display panel when screws are engaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten the display module to the jig system, then the display module can be securely fixed, but torsional force is applied to the bezel causing deformation and display abnormalities
Solution Approach 1:
The patent introduces a buffer cleavage as an intermediary element between the screw fastening point and the front-surface portion of the bezel. This buffer zone absorbs and dissipates the torsional force generated by screw engagement, preventing the force from being directly transmitted to the front-surface portion that contacts the display panel, thereby resolving the contradiction between secure fixing and bezel shape stability
Solution Approach 2:
The bezel is segmented into distinct functional zones: a front-surface portion that contacts the display panel, side portions for screw fastening, and buffer cleavages that separate these zones. This segmentation isolates the front-surface portion from torsional forces while maintaining overall structural integrity, allowing secure fastening without deformation
2Stability of the object's composition
If buffer cleavages are formed on the bezel edge to prevent torsional force transfer, then display abnormalities are reduced, but the structural strength of the bezel is weakened
Solution Approach 1:
The buffer cleavages are strategically positioned only at specific locations where torsional force transmission occurs, rather than uniformly across the entire bezel. This localized approach provides force isolation exactly where needed while preserving the structural strength and rigidity of the remaining bezel portions, resolving the contradiction between shape stability and structural strength

AI summary
The present invention relates to a housing structure for a display module. The structure comprises: a frame having a cavity for receiving a display module therein; and a bezel having a front-surface portion and a plurality of side portions connecting the front-surface portion thereto. When the bezel is assembled with the frame, the bezel enfolds part of the frame, and the front-surface portion of the bezel covers part of the surface of the display module. Besides, at least one of the side portions has at least one fastening hole and at least one protruding portion formed on a single side of the fastening hole away from the front-surface portion. Therefore, when the housing structure is fixed to an electronic device, the front-surface portion of the housing structure of the present invention will not press upon the surface of the display module.
