Flexible Display Module Recessed Middle Plate Deformation Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flexible displays, external forces cause deformation of the support layer, which can lead to shape distortions and exposure of surface irregularities on the window surface, compromising image quality.
Innovation Solution
The electronic device incorporates a housing with a middle plate featuring a recess and an adhesive layer with an opening, separating the support layer from the display, preventing deformation transfer when the support layer is deformed by external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support layer is attached over the entire area of the display to support the display, then the display structural stability is improved, but the support layer deformation transfers to the window surface causing shape distortion and surface irregularities
Solution Approach 1:
The adhesive layer is divided into a first portion and a second portion, with the first portion positioned over the recess and the second portion positioned away from the recess. This segmentation allows the support layer to be attached to the display in a controlled manner, preventing deformation transfer to the window surface while maintaining structural stability.
Solution Approach 2:
The recess is formed in the middle plate at a specific location corresponding to the first portion of the adhesive layer. This local structural modification creates a region where the support layer can be attached without transferring deformation to the window surface, while other areas maintain normal attachment for structural support.
2Strength
If the support layer is attached to the display, then structural support is provided, but surface irregularities of the middle plate are exposed to the window surface
Solution Approach 1:
The adhesive layer is segmented into first and second portions, with the first portion positioned over the recess. This segmentation allows the support layer to be attached for structural support while the recess configuration prevents middle plate irregularities from being exposed at the window surface.
Solution Approach 2:
The recess in the middle plate acts as an intermediary structure between the support layer and the display. It provides a configuration that allows structural support to be maintained while preventing the transmission of surface irregularities to the window surface.

AI summary
An electronic device is provided. The electronic device includes a housing, a display, a middle plate, an adhesive layer, a support layer, and a coating layer. The housing includes a front plate facing a direction, a rear plate facing an opposite direction, and a lateral member surrounding a space between the front and rear plate. The display is configured to be seen through the front plate, and includes a first and second surface. The middle plate is disposed between the display and the rear plate, and includes a surface facing the display, and a recess. The adhesive layer is attached to the display, and the support layer is disposed between the adhesive layer and the middle plate. The coating layer is disposed between the support layer and the adhesive layer and is disposed in a first portion overlapped with the recess when viewed from the display.
