ETCHING MASK FOR TEMPERED GLASS AND METHOD OF PROCESSING A TEMPERED GLASS SUBSTRATE FOR TOUCH SCREENS USING THE SAME

摘要

PURPOSE: An etching mask for tempered glass is provided to discharge static electricity generated in a sand blast processing due to the collision of abrasive particles to outside by including a conductive mask pattern and a ground wire. CONSTITUTION: An etching mask for tempered glass (100) comprises a conductive mask pattern (110) and a ground wiring (120). The conductive mask pattern is formed on a tempered glass disk (10) and selectively exposes the etching region of the tempered glass disk. Conductive constructs forming a touch screen are arranged in the tempered glass disk. The ground wiring is connected electrically with the conductive mask pattern. The ground wiring discharges static electricity generated in a sand blast processing to outside by spraying abrasive particles with superhigh speed. A processing method of a reinforced glass substrate for a touch screen comprises following steps. A tempered glass disk is prepared (S110). An etching mask for tempered glass is arranged on the tempered glass disk (S120). Static electricity generated in a sand blast processing due to the collision of abrasive particles is discharged to outside while the tempered glass disk is etched through the sand blast processing (S130).
