CAPACITIVE TYPE TOUCH SENSOR WITH OPTICAL FUNCTIONALITY |
摘要 |
A capacitive type touch sensor has optical functionality, low reflection and thin thickness as well as narrow frames. The capacitive type touch sensor includes a cover glass, and a capacitive type film sensor member adhered to a rear surface of the cover glass. The capacitive type touch sensor further includes a polarization plate between the cover glass and the film sensor member. The film sensor member includes a transparent base sheet having a λ/4 phase difference film, transparent conductive films so as to form electrode pattern s on the central windows and fine line routed circuit pattern on the peripheral frames on both sides of the base sheet, and light-blocking conductive films laminated on the fine line routed circuit patterns of the transparent conductive film. |

1. A capacitive type touch sensor with optical functionality, the touch sensor comprising:
a cover glass; and a capacitive type film sensor member adhered to a rear surface of the cover glass, the film sensor member including:
a transparent base sheet including a λ/4 phase difference film;a transparent conductive film formed so as to have an electrode pattern formed on a central window and a fine line routed circuit pattern formed on an peripheral frame, both of the patterns being formed on both sides of the base sheet; anda light-blocking conductive film laminated on each of the fine line routed circuit patterns of the transparent conductive film. |
