1. A method for coating a curved substrate, comprising:
providing a coating device comprising: a chamber, a carrying platform, a sputtering device, and a position-adjusting device, wherein the carrying platform is disposed in the chamber and has a first surface, the sputtering device comprises a sputtering target, the sputtering device is disposed in the chamber and is disposed corresponding to the carrying platform, and the position-adjusting device is disposed in the chamber and connected to at least one of the sputtering device and the carrying platform;
providing a curved substrate, wherein the curved substrate is disposed on the first surface of the carrying platform and the curved substrate has a second surface;
collecting data, wherein the data comprises a distance between a first part of the second surface of the curved substrate and the first surface of the carrying platform, and a distance between a second part of the second surface of the curved substrate and the first surface of the carrying platform;
storing the data in a processor;
adjusting the sputtering device to a first position and a second position in a first direction by the position-adjusting device according to the data stored in the processor, wherein the first direction is parallel to a normal direction of the first surface of the carrying platform; and
sputtering a coating material to the first part and the second part of the second surface of the curved substrate by the sputtering device, wherein when the sputtering device is at the first position in the first direction, the coating material is sputtered on the first part of the second surface of the curved substrate, and when the sputtering device is at the second position in the first direction, the coating material is sputtered on the second part of the second surface of the curved substrate.
