Supporting Frame Guide Bar Bonding for Narrow Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The narrow bezel structure in display apparatuses leads to a deterioration of bonding strength between the receiving container, supporting frame, and cover member, compromising the structural integrity of the display apparatus.
Innovation Solution
Incorporating first and second fixing portions on the supporting frame that are stably fixed to the receiving container using guide bars, reducing movement and enhancing the bonding strength between the supporting frame and the receiving container, especially in the light incident area of the backlight unit.

Engineering Contradiction Analysis
1Volume of moving object
If a narrow bezel structure is employed to reduce the overall outer size of the display apparatus, then the compactness and aesthetic appearance are improved, but the bonding strength between the receiving container, supporting frame, and cover member deteriorates
Solution Approach 1:
The supporting frame is divided into multiple segments including a first supporting frame portion, a second supporting frame portion, and a bridge portion connecting them. This segmentation allows the frame to maintain structural integrity while adapting to the narrow bezel configuration, distributing mechanical stresses across multiple connection points rather than relying on a single large bonding area that would require more space.
Solution Approach 2:
The bridge portion of the supporting frame is specifically designed with enhanced bonding structures including protrusions and recesses that interlock with the receiving container. This local quality enhancement concentrates bonding strength at critical locations where the narrow bezel would otherwise compromise overall bonding, allowing the structure to maintain strength despite reduced overall dimensions.
2Length of stationary object
If the bezel width is reduced to achieve a narrower profile, then the display apparatus becomes more compact and modern, but the structural stability and bonding strength in the light incident area deteriorate
Solution Approach 1:
The bridge portion extends in multiple dimensions with vertical protrusions and horizontal recesses creating a three-dimensional interlocking structure. This dimensional complexity allows the bonding interface to maintain stability despite reduced bezel width, as the multi-dimensional engagement distributes mechanical loads across different spatial planes rather than relying solely on lateral bonding area.
Solution Approach 2:
The supporting frame and receiving container utilize complementary geometric features (protrusions and recesses) that create a composite bonding structure. This composite approach combines mechanical interlocking with adhesive bonding, creating a hybrid connection that maintains structural stability in the narrow bezel configuration where traditional single-method bonding would fail.

AI summary
A display apparatus includes a display unit which displays an image, a backlight unit which provides the display unit with a light, a receiving container which accommodates the backlight unit, and a supporting frame which is coupled to the receiving container and supports the display unit. The backlight unit includes a light incident area from which the light is emitted. The receiving container includes a guide bar which is adjacent to the light incident area of the backlight unit and coupled to the supporting frame.
