Abstract

표시장치는 직선 형광펌프와 도광판을 지니고 있다. 도광판은 뒤에 램프 부근에 V자 모양의 노치와 정면에 만곡면을 지닌다. V자 모양의노치는 램프로부터 광을 수용하고 이를 만곡면에 전달하는 정사면을 지닌다. 램프로부터의 광이 문자판을 효율적으로 조사시키기 위해 만곡면에 의해 전반사된다.The display device has a linear fluorescent pump and a light guide plate. The light guide plate has a V-shaped notch behind the lamp and a curved surface on the front. The V-shaped notch has an orthogonal plane that receives light from the lamp and transmits it to the curved surface. Light from the lamp is totally reflected by the curved surface in order to irradiate the dial efficiently.
