Abstract: 본 발명은 휴대폰의 기능표시와 번호표시를 하는 키 판(Key board)에 대한 것으로, 보다 상세하한 설명으로는 지금까지 시판되고 있는 대부분의 앞면 키 판을 플라스틱재질로 제작해 왔으나 손때 등으로 변색되어 장기간 사용하면 낡은 표시가 생겨 오랫동안 사용할 때 거부감을 갖는 등 외부적인 디자인의 유지가 어려웠다. 
     이러한 점을 개선하기 위해 연구와 연구 및 고심 속에서 색상을 오랜 기간 유지시킬 수 있는 도색방법을 개발하고 실시하여 성공하므로 이를 상품화하고자 출시하기 전에 고유성을 갖기 위해 출원하는 발명내용인데 이러한 에칭(Echting)은 얇은 구리판에 실시한 방법을 알루미늄 판에 실시하여 같은 효과를 얻은 것이다. 
     도색방법은 양극산화처리(anodizing) 공정에서 미세한 구멍을 만들도록 하여 그 속에 염료를 채우는 방식인데 이에 의한 도색은 변색은 물론 탈색의 염려도 없어서 아주 훌륭한 도색방법이고 이 도색처리 후 그 위에 특수 세라믹 투명 코팅을 하면 지문 등의 오염도 안 되는 장점까지 지니고 있어서 플라스틱보다 가벼우면서 변색되지 않고 중금속 등의 오염이 없는 방식으로 다양한 색상도 발현시킬 수 있어서 내수시장은 물론 해외시장에 이르기까지 큰 시장 확보가 가능하게 되었다.
