Abstract
The present disclosure provides an electronic device including a covering layer and a flexible substrate structure. The covering layer includes a first region and a second region. The flexible substrate structure is disposed under the covering layer and includes a first portion corresponding to the first region and a second portion corresponding to the second region. A Gaussian curvature of the first region of the covering layer is different from a Gaussian curvature of the second region of the covering layer, and a Poisson's ratio of the first portion of the flexible substrate structure is different from a Poisson's ratio of the second portion of the flexible substrate structure.
Claims9
An electronic device, comprising:
- a covering layer comprising a first region and a second region;
- and
- a flexible substrate structure disposed under the covering layer and comprising a first portion corresponding to the first region and a second portion corresponding to the second region,
- wherein an absolute value of a Gaussian curvature of the first region of the covering layer is less than an absolute value of a Gaussian curvature of the second region of the covering layer, and a Poisson's ratio of the first portion of the flexible substrate structure is greater than zero and a Poisson's ratio of the second portion of the flexible substrate structure is less than zero.
