    摘要： The present disclosure relates to curved cover glass used for a curved display, and a manufacturing method thereof. The present disclosure provides tempered glass comprising: glass including a curved area; and a low-reflection coating layer, coated on a surface of the glass, composed of a mixture of a binder and a hollow material, wherein the glass comprises potassium ions which penetrate up to a predetermined depth therein. According to the present disclosure, a low-reflection coating layer is formed prior to curved surface processing, and thus, the low-reflection coating layer can be uniformly formed even on areas having different curvatures. Thus, the present disclosure can minimize the color difference generated in curved glass due to low-reflection coating layers.

    摘要： A mold apparatus for bending a glass sheet includes a main frame structure and a first mold arrangement having a first mold and a guide frame connected to the first mold. A first guide member of the guide frame is guidable by the frame structure such that it is inhibited from moving laterally in any direction, and a second guide member of the guide frame is guidable by the frame structure such that it is movable laterally away from the first guide member due to thermal expansion. The apparatus further includes a second mold arrangement including a second mold and a frame that supports the second mold such that the second mold is movable laterally relative to the frame. A sensor is also included for sensing position of one of the molds to determine whether the one mold is in a suitable position for mating with the other mold.
