Side-Surface Display Adhesive Structure for Minimal Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bezel of a display in electronic devices limits the user's sense of immersion due to its non-display area, hindering the maximization of the screen area without increasing the device size.
Innovation Solution
A display is fixed to a housing using an adhesive material positioned at the side surface, eliminating the need for a separate mounting portion at the edge, and incorporating conduits for the adhesive to adhere the window layer to the frame, reducing the bezel area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive material is positioned at the outer edge of the display, then the display can be fixed to the housing, but the bezel area increases and display area is reduced
Solution Approach 1:
The adhesive material is repositioned from the outer edge (2D plane at the display perimeter) to the side surface (vertical dimension), effectively moving the adhesive application from a horizontal boundary to a vertical mounting surface. This dimensional shift allows the adhesive to secure the display without occupying display area or increasing bezel size.
2Reliability
If a separate mounting portion is formed in the housing edge, then the adhesive material can be positioned for display fixation, but the bezel area increases
Solution Approach 1:
The mounting portion functionality is merged with the side surface of the housing itself, eliminating the need for a separate, distinct mounting structure. The adhesive material is applied directly to the side surface, combining the structural support function with the mounting function, thereby simplifying the overall housing structure while maintaining fixation reliability.
3Reliability
If adhesive material is disposed under the edge of the display, then the display can be adhered to the housing, but the bezel area increases covering the adhesive
Solution Approach 1:
The adhesive material is extracted from the display edge area and repositioned to the side surface of the housing. This extraction removes the adhesive from the visual display area and bezel region, allowing the adhesive to perform its bonding function without requiring any bezel area to cover it, thereby maximizing the display area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration increases the display area by minimizing the bezel, enhancing user immersion without enlarging the device size.
Implementation Method 1
an adhesive material introduced into the first conduit to adhere the side surface of the window layer to the housing and the frame

AI summary
An electronic device according to the present disclosure may comprise: a window layer of which at least a part is transparent; a display disposed under the window layer; a housing including a front surface on which the display is disposed, a rear surface opposite to the front surface, and a side surface surrounding a space between the front and the rear surface; a frame surrounding the side surface of the housing and the side surface of the window layer; a first conduit formed on at least one of a surface of the frame facing the housing and the side surface of the housing facing the frame, the first conduit extending from the rear surface of the electronic device to the front surface; and an adhesive material which is introduced into the first conduit to bond the side surface of the window layer to the housing and the frame.
