  • Publication number: 20180186690
    Abstract: The present invention relates to a manufacturing method for a camera window and a camera window manufactured thereby. A conventional camera window is configured such that an etching pattern is provided on a back surface of a glass sheet, and a deposition layer is provided on the etching pattern, thereby improving reflectivity, whereby indirect external recognition of the etching pattern is performed, but in the present invention, a distinctive pattern is provided on a front surface of a glass sheet such that direct external recognition of the pattern is possible, whereby it is possible to recognize a distinctive pattern line.
