Abstract

A light-emitting display device (1) has visible light emitters (2) that display alarm, information, etc., based on display signals. The display signals are modulated (3) by data signals related to the alarm and information and emitted in the form of multiplex-modulated data light from the visible light emitters (2). The modulated data light is received by a light receiver (6), demodulated (9), and is displayed (10, 11). The light receiver (6) is carried by a pedestrian or is mounted on a car. This constitution supplements insufficient transfer of information such as the one that may happen when one fails to look at the information displayed by the visible light emitter (2), and makes it possible to reliably transfer the information. This constitution further supplements the amount of information displayed by the visible light emitter (2), and makes it possible to transfer information in sufficient amounts.

Many are arranged in a box shape. A display signal is supplied to each element 2 via the modulation section 3 and the light emission drive section 4, and as a result, characters and symbols for alarms, information, and the like are displayed by visible light emission. Information on this display can be read by surrounding pedestrians, car drivers, and the like. If necessary. The characters and symbols displayed on the light-emitting display tower 1 are scrolled (forward) in the circumferential or vertical direction.

The data signal connected to the display information is supplied to the modulator 3 that multiplexes the above-mentioned display signal and this data signal. The display signal is modulated with this data signal by, for example, a 5 MHz carrier FM method. Therefore, since the light emission of the display element 2 is multiplex-modulated at 5 MHz FM, the data signal is transmitted from the element 2 as an optical signal. This data signal causes the intensity of light in the display signal that is not recognized as visible information due to the afterimage characteristics of the eye. If necessary, the light emitting elements 2 may be divided into those used for display and those used for data transmission. In this case, the light emitting element 2 used exclusively for data transmission may be an infrared light emitting element.
