发明名称 ECD DRIVING CIRCUIT
摘要 PURPOSE:To prevent a large current from being conducted transiently, and to improve the life of an ECD by providing a load resistance inserted through in series to an electrode. CONSTITUTION:A resistance 10 is inserted through in series between an anode 2 and a driving power source 5, and by an oscillator 4, the driving power source 5 is driven periodically by a high frequency, and a pulse voltage is applied between the electrodes 2, 3. In this case, at the time t0, when a pulse voltage rises, the drawing of an electron from a polyaniline thin film is generated and color forming is started, therefore, a current is conducted between both the electrodes 2, 3. A current value in this case is a value which is determined by a resistance 13, and it does not become high transiently. Also, since a current is limited by this resistance 13, the current is conducted steadily, and during this time, the electron is drawn out of the polyaniline thin film, and an anion in a solution is taken into the polyaniline thin film so as to compensate drawn out electron, by which the polyaniline thin film forms a color.
