Front Plate Step Structure to Hide Display Bezel Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to achieve a harmonious design when the display screen is off, with visible components like adhesive members and bezels detracting from a seamless appearance.
Innovation Solution
The display device incorporates a front plate with a flat portion and an end portion, where the end portion overlaps the bezel and has a shorter distance from the viewer's side face to a reference plane, and an adhesive member is placed to overlap this end portion, ensuring minimal visibility of the adhesive member and bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the front plate is designed with an end portion overlapping the bezel and a shorter distance to the reference plane, then the visibility of adhesive members and bezel is minimized, but the manufacturing complexity increases
Solution Approach 1:
The front plate is segmented into a flat portion and an end portion with different thicknesses. The end portion has a shorter distance to the reference plane compared to the flat portion, creating a stepped structure that hides the adhesive member while maintaining manufacturing feasibility through separate molding or assembly steps
Solution Approach 2:
The solution transitions from a two-dimensional planar front plate to a three-dimensional stepped structure by varying the thickness in the vertical dimension. This dimensional change allows the end portion to overlap the bezel and conceal the adhesive member, resolving the contradiction between appearance and manufacturing complexity
2Shape
If the adhesive member is placed to overlap the end portion, then the appearance is improved by minimizing visibility, but the manufacturing precision requirements increase
Solution Approach 1:
The end portion is pre-formed with a specific shape and position during front plate manufacturing, creating a built-in guide structure. The adhesive member is then placed to overlap this pre-formed end portion, which serves as a reference feature that simplifies positioning and reduces the actual placement precision requirements
Solution Approach 2:
The end portion acts as an intermediary element between the adhesive member and the bezel. By providing this intermediate structure with a shorter distance to the reference plane, the system achieves better appearance while the end portion itself serves as the positioning reference, reducing the precision burden on the adhesive placement process
3Shape
If the front plate includes a flat portion not overlapping the bezel and an end portion overlapping the bezel, then the harmonious appearance is achieved, but the device complexity increases
Solution Approach 1:
Different regions of the front plate are given different local qualities: the flat portion maintains a standard thickness for structural integrity and display alignment, while the end portion has a reduced thickness to overlap the bezel and hide the adhesive. This localized differentiation achieves appearance harmony without requiring complete redesign of the entire front plate structure
Solution Approach 2:
The front plate is divided into functionally distinct segments: a flat portion for primary structural support and display alignment, and an end portion for aesthetic integration with the bezel. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural coherence and manufacturing feasibility

AI summary
A display device includes a display panel, a housing that stores the display panel and includes a bezel placed around the display panel in a plan view, a front plate placed on a viewer's side of the display panel, at least part of the front plate overlapping the bezel, and an adhesive member bonded to the front plate, in which the front plate includes a flat portion that does not overlap the bezel and an end portion that overlaps the bezel, when a plane obtained by virtually expanding a viewer-side face of the display panel is defined as a reference plane, a distance between a viewer-side face of the end portion and the reference plane is shorter than a distance between a viewer-side face of the flat portion and the reference plane, and at least part of the adhesive member overlaps the end portion.
