Display Panel Notch Support for Narrow-Bezel Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have a wide connection surface between the display panel and the middle frame, resulting in a large frame due to the need for a relatively wide connection area, which contradicts the market demand for narrow bezels.
Innovation Solution
A display device design featuring a display panel with a first notch on the cover plate and a supporting member with multiple sections that are snap-fitted into notches, allowing the middle frame to overlap the display substrate, reducing the bezel width by minimizing the connection surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relatively wide connection surface is reserved on the cover plate to connect the display panel with the middle frame, then the connection stability is improved, but the frame size becomes large
Solution Approach 1:
The supporting member is divided into multiple sections (first supporting section, second supporting section, third supporting section) that are connected sequentially. Each section serves a specific function: the first section connects to the middle frame, the second section fits into the first notch to provide support, and the third section connects to the display substrate. This segmentation allows the connection structure to be more compact while maintaining stability.
Solution Approach 2:
The second supporting section of the supporting member is partially arranged in the first notch of the cover plate, creating a nested configuration. The first notch extends along the thickness direction of the cover plate, allowing the supporting member to be embedded within the cover plate structure. This nesting reduces the overall frame size while maintaining connection stability.
2Length of stationary object
If the middle frame is positioned closer to the display substrate to reduce bezel width, then the aesthetic appearance is improved, but the structural integrity may be compromised
Solution Approach 1:
The supporting member acts as an intermediary component between the middle frame and the display substrate. It includes a first supporting section connected to the middle frame, a second supporting section that fits into the first notch of the cover plate, and a third supporting section connected to the display substrate. This intermediary structure allows the middle frame to be positioned closer to the display substrate while maintaining structural integrity through the distributed support provided by the supporting member.
3Productivity
If the connection surface area is minimized to achieve narrow bezel, then the productivity is improved, but the ease of manufacture may be affected
Solution Approach 1:
The first notch and second notch are pre-formed in the cover plate during the manufacturing process. The first notch extends along the thickness direction of the cover plate, and the second notch is arranged at the side surface of the cover plate. These pre-formed notches guide the positioning and assembly of the supporting member, making the assembly process simpler and more efficient despite the reduced connection surface area.

AI summary
The present disclosure is related to a display device. The display device includes a middle frame, a display panel and a supporting member. The middle frame is provided with a first mating surface. The display panel includes a display substrate and a cover plate. A first notch is provided at a side of an edge of the cover plate close to the first mating surface. The first notch extends along a thickness direction of the cover plate. An orthographic projection of the display substrate on the cover plate at least partially overlaps an orthographic projection of the first mating surface on the cover plate. The supporting member includes a first supporting section and a second supporting section, the first supporting section is connected to the first mating surface, and the second supporting section is partially arranged in the first notch.
