Abstract

A method for manufacturing a display device and a cover plate thereof is provided. The method for manufacturing the cover plate includes the following steps: providing a glass substrate having a first surface and a second surface opposite to the first surface; performing a laser half-cutting process on the glass substrate to form a cutting path on the glass substrate; forming an ink layer on the first surface of the glass substrate; forming a functional layer on the first surface of the glass substrate and the ink layer; and after forming the functional layer, cleaving the glass substrate to obtain the cover plate.

Claims

1. A method for manufacturing a cover plate, comprising: A glass substrate is provided, the glass substrate having a first surface and a second surface opposite to the first surface; A laser half-cutting process is performed on the glass substrate to form a cutting path on the glass substrate; An ink layer is formed on the first surface of the glass substrate; a functional layer is formed on the first surface of the glass substrate and the ink layer; And after forming the functional layer, the glass substrate is cleaved to obtain the cover plate.

2. The method of manufacturing the cover plate as described in claim 1, further comprising: Before the glass substrate is cleaved, a touch sensing layer is formed on the second surface of the glass substrate.

3. A method for manufacturing a cover plate as claimed in claim 1, wherein the laser half-cutting process includes: Laser light is used to form multiple openings in the glass substrate along a predetermined path.

4. The method of manufacturing the cover plate as described in claim 3 further includes: Before the ink layer is formed, the glass substrate is subjected to a strengthening process to strengthen the first surface, the second surface, and the sidewalls of the plurality of openings of the glass substrate.

5. A method for manufacturing a cover plate as claimed in claim 1, wherein cleaving the glass substrate comprises: Stress is applied to the glass substrate to separate it along the cutting path.

6. A method for manufacturing a cover plate as claimed in claim 2, wherein after the glass substrate is cleaved, the sidewalls of the touch sensing layer, the ink layer, and the functional layer are substantially flush with the sidewalls of the glass substrate.

7. A display device, comprising: Display panel; A light guide plate is disposed on the display panel; The cover plate is disposed on the light guide plate, wherein the cover plate includes: a glass substrate having a first surface and a second surface opposite to the first surface; an ink layer disposed on the first surface of the glass substrate; a functional layer disposed on the first surface of the glass substrate and the ink layer; and a touch sensing layer disposed on the second surface of the glass substrate, wherein the touch sensing layer is directly formed on the second surface of the glass substrate and in direct contact with the glass substrate, and no adhesive layer is disposed between the touch sensing layer and the glass substrate, the touch sensing layer and the glass substrate constitute a touch panel, such that the cover plate includes the touch panel.

8. The display device as claimed in claim 7, wherein the sidewall of the touch sensing layer is substantially flush with the sidewall of the glass substrate.

9. The display device as claimed in claim 7, wherein the sidewall of the touch sensing layer is substantially flush with the sidewall of the ink layer.
