Bracket Beam Design for Narrow Display Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device structures face challenges in achieving sufficient bonding strength between the outer chassis and the front surface plate, and in securing a bonding surface for the display cover support case, particularly around flexible printed circuits, which limits the reduction of the frame region's area relative to the display device's outer dimensions.
Innovation Solution
The display device incorporates a bracket with a side wall portion fixed to the chassis and a beam portion that extends along the side of the front surface plate, providing an adhesive region between the display panel and the front surface plate, and using double-sided tapes to bond the front surface plate to the chassis, thereby increasing the bonding area and reducing the frame region's width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the outer chassis is widened to increase the bonding area with the front surface plate, then the bonding strength is improved, but the frame region area increases relative to the display device outer dimensions
Solution Approach 1:
The bracket extends in the depth direction (third dimension) rather than only in the planar direction, allowing the bonding area to be increased without widening the frame region's external dimensions. The beam portion protrudes into the space between the display panel and front surface plate, creating additional bonding area in the depth dimension.
Solution Approach 2:
The bracket is divided into distinct functional portions: a side wall portion for fixing to the chassis and a beam portion for bonding to the front surface plate. This segmentation allows each portion to be optimized independently, with the beam portion extending to provide additional bonding area without increasing the overall frame footprint.
2Strength
If the intermediate member is made larger than the display panel to ensure sufficient bonding area, then the bonding strength is improved, but the device complexity increases
Solution Approach 1:
The bracket serves multiple functions simultaneously: it acts as a structural support element, provides a bonding interface between the chassis and front surface plate, and creates the necessary gap for the display panel. This multi-functionality eliminates the need for a separate intermediate member with enlarged dimensions, reducing overall device complexity.
3Ease of manufacture
If the FPCs are drawn to the rear of the display cover support case, then the assembly process is simplified, but the bonding area for fixing the cover glass is reduced
Solution Approach 1:
The bracket's beam portion extends into the depth direction to provide additional bonding area, compensating for the space occupied by the FPCs. This allows the FPCs to be routed to the rear while maintaining sufficient bonding area for fixing the cover glass through the adhesive portion on the beam portion's front surface.

Function Achieved in This Case
This configuration enhances the bonding strength between the chassis and the front surface plate, allows for a narrower frame region, and facilitates easier assembly by maintaining a sufficient adhesive area, while preventing the peeling of the cover glass and ensuring display quality.
Implementation Method 1
a front surface plate that is disposed in front of the display panel, and that holds the display panel in a suspended state via an optical elasticity resin layer
Implementation Method 2
a bracket that is fixed to a side face of the chassis and bonded to a rear surface of the front surface plate by an adhesive portion

AI summary
A display device includes a display panel disposed in front of a chassis, a front surface plate disposed in front of the display panel and holding the display panel in a suspended state via an optical elasticity resin layer, and a bracket fixed to a side face of the chassis and bonded to a rear surface of the front surface plate by an adhesive portion. The bracket includes a side wall portion that is fixed to the side face of the chassis, rises from rear to front, and extends along a side of the front surface plate, and a beam portion in front of the side wall portion. The beam portion extends along the side of the front surface plate, and protrudes along the rear surface of the front surface plate, from the side wall portion to a space between the display panel and the front surface plate.
