Display Module Holding Member with Gap for Frame Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in achieving a thinner and lighter form factor due to deformation of the frame, which can lead to unevenness in the display and light leakage, especially when the frame is warped during manufacturing or assembly.
Innovation Solution
A display module design featuring a frame with an opening over the display surface and a holding member with a gap between its inner and outer regions, connected to the display panel and frame respectively, allowing for deformation absorption and preventing panel deformation, while using a light-blocking film and double-faced tape for bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the display panel is fixedly bonded to the frame with a double-faced tape, then the display panel can be securely attached, but the frame may deform causing the display panel to deform and creating unevenness in display
Solution Approach 1:
The holding member is divided into a first holding portion connected to the display panel and a second holding portion connected to the frame, with a gap between them. This segmentation allows independent movement of each portion, enabling the second holding portion to absorb frame deformation while the first holding portion maintains stable connection to the display panel, preventing display unevenness.
Solution Approach 2:
The holding member acts as an intermediary between the display panel and the frame. By introducing this intermediate component with a gap structure, it decouples the direct rigid connection, allowing the holding member to absorb dimensional changes and deformation from the frame through elastic deformation or gap variation, thereby protecting the display panel from deformation.
2Ease of manufacture
If the frame is warped during manufacturing, then assembly becomes difficult, but a gap is generated between the frame and display panel causing light leakage
Solution Approach 1:
The holding member introduces dynamic adaptability to the assembly structure. The gap between the first and second holding portions allows the holding member to dynamically adjust to frame warpage or dimensional variations during assembly, maintaining contact between the display panel and frame without generating harmful gaps that would cause light leakage.
3Reliability
If a sandwiching structure is used to support the display panel, then the display panel is well supported, but the device thickness increases
Solution Approach 1:
The invention transitions from a three-dimensional sandwiching structure (requiring space on both sides of the display panel) to a two-dimensional planar holding structure. The holding member with its gap is arranged in a plane, allowing the display panel to be supported from one side only, thereby reducing device thickness while maintaining support stability through the distributed holding portions.

Function Achieved in This Case
This configuration prevents display panel deformation and light leakage, enabling a thinner and lighter device without the need for sandwiching the panel on both sides, thus allowing for a more compact and efficient display module.

AI summary
A display module includes a display panel configured to display an image on a display surface, a frame having a shape configured to surround an outer edge of the display panel and having an opening formed in a region overlapping the display surface, and a holding member having an inner region that is a region closer to a center of the display panel and an outer region that is a region farther from the center of the display panel, the inner region being connected to the display panel, the outer region being connected to the frame, and the inner region being separated from the outer region in a view projected from a direction orthogonal to the display surface.
