摘要：An optical interface using indicator lights is provided for an appliance having a
vacuum fluorescent display (VFD) by mounting the indicator lights behind a VFD. In a VFDhaving a dark background, apertures are formed in the VFD so the indicator lights areenabled for optical communication through the VFD. Preferably, the apertures areformed in the dark layer covering a glass substrate in the VFD so the dark layer helpsabsorb reflected light that may cause optical noise in the light signals being
communicated. Each aperture may be located equidistantly from a group of four pixels inthe VFD.
