Description

Glass Plate Strengthening Device and Glass Plate Strengthening Method Using the Same The present invention relates to a glass plate strengthening device and a glass plate strengthening method using the same, and more specifically, to a glass plate strengthening device that reduces product defects and a glass plate strengthening method using the same. A display device is a device that provides images to a user and is used in various multimedia devices such as televisions, mobile phones, tablet computers, and game consoles. A display device includes various modules to display images. Additionally, a display device includes a cover glass to protect the modules of the display device. Recently, to reduce the weight of display devices and improve user convenience, display devices are being designed to have a thin thickness.
