    摘要: Disclosed is an optical filter and a method of manufacturing the same, the optical filter including a tempered glass substrate and an optical filter formed on upper and lower surfaces of the tempered glass substrate and the method including: forming a sheet-cutting portion on a base glass substrate on a per-cell basis; tempering the base glass substrate such that upper and lower surfaces of the base glass substrate are tempered and a side portion thereof is tempered through the sheet-cutting portion as well; forming an optical filter layer on each of upper and lower surfaces of the base glass substrate; and dividing the base glass substrate into cells where each cell serves as a cell-based optical filter.

    摘要: Disclosed is a glass-based flexible cover window with improved strength including a planar portion formed so as to correspond to a planar region of a flexible display and a folding portion formed so as to be connected to the planar portion, the folding portion being formed so as to correspond to a folding region of the flexible display, wherein the flexible cover window includes a glass substrate, an adhesive buffer layer formed on the glass substrate, a protective film layer formed on the adhesive buffer layer, and a hard coating layer formed on the protective film layer. The protective film layer is formed on the glass substrate, whereby strength and folding characteristics of the flexible cover window are improved, and inherent texture of glass is maintained while the overall thickness of the flexible cover window is reduced, and therefore aesthetics of the flexible cover window are improved.

    摘要: Proposed is a flexible cover window manufacturing method capable of simultaneously reinforcing a plane part and a folding part by using alkali-based metal ions having an ionic radius smaller than that of alkali-based metal ions contained in a glass. A flexible cover window manufactured using the same method is also proposed. The plane part and the folding part are simultaneously reinforced using alkali-based metal ions having a smaller ionic radius than alkali-based metal ions included in a glass to simplify the process, and the flexible cover window ensures strength and folding characteristics by controlling tensile stress of the entire part of the flexible cover window.

    摘要: A method of manufacturing a flexible cover window is proposed. The flexible cover window includes a planar part and a folded part extending continuously from the planar part, wherein the folded part is thinner than the planar part. The method includes: forming a photoresist layer on a glass substrate, patterning the photoresist layer to form a gradation resist pattern layer for forming the folded part on the glass substrate, forming the folded part having an inclined portion formed between the folded part and the planar part using the gradation resist pattern layer as a mask, removing the gradation resist pattern layer, and reinforcing the glass substrate.
