There are also a variety of smart devices that start with smartphones with relatively small touch panels and even large tablets.
최근에는 소위 3D 터치패널로 불리우는 곡면 터치패널에 대한 관심도가 높아지고 있다. 이러한 곡면 터치패널은 심미감은 물론 실질적으로 패널의 터치 면적을 증가시킬 수 있다.Recently, interest in curved touch panels called 3D touch panels has increased. Such a curved touch panel may increase the touch area of the panel as well as the aesthetics.
한편, 이와 같은 곡면 터치패널을 제조하기 위해서는 터치패널에 커버 글라스로 사용되는 유리를 곡면으로 성형하여야 한다.Meanwhile, in order to manufacture such a curved touch panel, the glass used as the cover glass in the touch panel must be molded into a curved surface.
이러한 글라스 곡면 성형방법으로는, 글라인드 등으로 글라스 면을 연마하여 곡면으로 제조하는 방법이 많이 이용되었다. 그러나, 이러한 연마 방법은 글라스의 표면 조도 및 투과율을 맞추기 위한 노력이 필요하고, 연마시 주어지는 큰 저항으로 인해 스크래치나 글라스의 파손율이 높고, 성형 시간이 많이 소요되어 생산성이 떨어지는 문제가 있었다.As the glass curved surface forming method, a method of grinding the glass surface with a blind or the like to produce a curved surface has been frequently used. However, such a polishing method requires efforts to match the surface roughness and transmittance of the glass, and has a problem of high scratch or glass breakage rate due to a large resistance given during polishing, and a large amount of molding time, resulting in low productivity.
