Abstract
An identification card includes a ceramic substrate with opposite surfaces, and an accommodating part. A marking joint part is arranged in the accommodating part, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate. The marking joint part includes a bearing layer and a marking part arranged on the bearing layer. The bearing layer and the marking part are of an integrated structure. The ceramic substrate is provided with an accommodating part for setting a marking joint part to ensure the flatness of the identification card, and the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate.
Claims15
An identification card, comprising:
- a ceramic substrate with opposite surfaces, wherein the substrate is provided with an accommodating part extending from at least one of the surfaces;
- and
- a marking joint part arranged in the accommodating part,
- wherein the orthogonal projection of the accommodating part on the ceramic substrate covers the orthogonal projection of the marking joint part on the ceramic substrate, and the marking joint part comprises a bearing layer and a marking part arranged on the bearing layer,
- wherein a length, width and other measurements of the marking joint part are configured to fill a length, width and other measurements of the accommodating part;
- wherein the bearing layer and the marking part are of an integrated structure;
- wherein the orthogonal projection of the bearing layer on the accommodating part covers the orthogonal projection of the marking part on the accommodating part;
- wherein an adhesive is arranged between the integrated structure and the ceramic substrate.
