Curved Display Cover Glass Binding with Flat Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved displays face issues with uneven binding forces and inaccurate alignment between curved surfaces of the frame body and cover glass, leading to glue leakage and alignment problems during assembly.
Innovation Solution
The method involves using a frame body with flat surfaces and a cover glass with alignment marks, where an image capturing apparatus is used to align the marks, allowing for precise positioning and adherence with double-sided tapes, followed by filling an optical adhesive between the components.

Engineering Contradiction Analysis
1Shape
If two curved surfaces are bound to each other to combine the frame body and cover glass, then the binding matches the curved shape, but uneven binding force occurs causing glue leakage
Solution Approach 1:
The curved binding surface is divided into multiple flat binding areas through binding ribs protruding from the frame body. Each flat binding area provides a separate, uniform binding interface that avoids the uneven contact problems of a continuous curved surface, while collectively forming the desired curved display shape.
Solution Approach 2:
The flat binding areas are nested within the curved frame body structure. The binding ribs create localized flat planes that are embedded in the curved surface, allowing the cover glass to bond uniformly on these flat areas while the overall assembly maintains the curved configuration.
2Shape
If two curved surfaces are bound to each other, then the curved shape is maintained, but alignment between the surfaces becomes difficult
Solution Approach 1:
The curved surface is segmented into discrete flat binding areas marked with alignment marks. These segmented flat areas serve as precise alignment targets that are easier to measure and position accurately compared to continuous curved surfaces, improving alignment precision during assembly.
Solution Approach 2:
Alignment marks are provided on the flat binding areas to facilitate visual alignment during the bonding process. These marks enable precise positioning and alignment between the frame body and cover glass by providing clear visual references on the otherwise difficult-to-align curved surfaces.
3Ease of operation
If alignment marks are provided on curved surfaces, then alignment can be facilitated, but the marks are difficult to position accurately
Solution Approach 1:
Alignment marks are positioned on flat binding areas rather than on curved surfaces. This segmentation of the marking location to flat planes enables much more accurate and consistent positioning of the alignment marks, as flat surfaces provide stable, measurable reference planes that are easier to manufacture with high precision.

AI summary
A curved display and a method for binding a cover glass of the curved display are provided. The curved display includes a display module, a frame body and a cover glass. The frame body has a first flat surface and a second flat surface opposite to the first flat surface, in which the first flat surface is adhered to the display module. The cover glass has a binding flat surface and an application surface opposite to the binding flat surface, in which the binding flat surface is adhered to the second flat surface of the frame body, and the application surface is a surface with curvature. The second flat surface of the frame body is set with a first alignment mark, and the binding flat surface of the cover glass is set with a second alignment mark, and the first alignment mark corresponds to the second alignment mark.
