An organic EL display device includes a first substrate, a plurality of organic EL devices arranged on the first substrate, a second substrate arranged above the first substrate, and a filling layer arranged between the first substrate and the second substrate, and displays an image on the second-substrate side. The low pass filter provides a low impedance path for only voice band signals, while blocking signals that fall within the high frequency range of digital data that may be present on the telephone line. The models can be constructed from training text selected to reflect a particular kind of text entity. An edge flange is disposed on each panel edge encompassing an entire panel outer periphery. Period and duty cycle counters provide duty cycle ratios from the delta-sigma modulator for comparison of changes in capacitance values of a capacitive sensor when an object is in proximity thereto.
