Display Device Bezel Joining Member Backside Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing their size while maintaining the size of the display area, as the bezel's width cannot be sufficiently minimized when viewed from the front, limiting the ratio of display area to device size.
Innovation Solution
The display device incorporates a bezel with elongated bezel portions and joining members that overlap the display module on its backside, allowing for a reduced width when viewed from the front by overlapping the bezel portions and metal brackets, enabling a smaller device size without compromising the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bezel width is reduced to decrease device size, then the device footprint is reduced, but the structural strength and stability of the bezel deteriorate
Solution Approach 1:
The patent moves the joining members from the front view plane to the backside of the display module, utilizing the third dimension (depth) to resolve the contradiction. By positioning joining members at the backside, the bezel width at the front can be minimized while maintaining structural integrity through the distributed joining members at the back, effectively separating the aesthetic/front-facing dimension from the structural/back-facing dimension.
Solution Approach 2:
The bezel is divided into multiple separate bezel portions (first, second, third, and fourth bezel portions) that are joined by multiple joining members distributed at the backside. This segmentation allows each bezel portion to be independently positioned and joined, providing flexible structural support without requiring a wide continuous bezel at the front.
2Area of moving object
If the bezel width is reduced to increase display area ratio, then the display area to device size ratio is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The bezel is segmented into multiple independent bezel portions that can be manufactured separately and then assembled using joining members at the backside. This segmentation enables flexible manufacturing where each portion can be produced independently and assembled in a modular fashion, simplifying the overall manufacturing process despite the reduced bezel width.

AI summary
Provided is a display device that is easily reduced in size, while maintaining a size of a display area. The display device includes a display module including a display panel that displays an image in a display area provided at a front, and a bezel surrounding an outer edge of the display module. The display area has a rectangular shape. The bezel includes a plurality of bezel portions having an elongated shape and disposed to correspond to respective four sides of the display area, and a joining member joining together two adjacent bezel portions of the plurality of bezel portions. The joining member is disposed in a position where the joining member overlaps the display module on a back side of the display module.
