Abstract

An interactive soft toy with a light emitting diode device mounted within the soft toy. The light emitting diode device has a translucent front cover and translucent sheet to which a graphic pattern is applied. The light emitting diode device is operative to display a pattern. When the pattern of the light emitting diode panel is illuminated, the graphic pattern is overshadowed thereby. The on/off status of the light emitting diode units can be controlled by a manual input device, an infrared signal, or an audio signal. The light emitting diode device further has a speaker for generating a sound effect corresponding to the pattern displayed by the light emitting diode device.
