Driving method for electrochromic display body

摘要: PURPOSE: To execute display which is stable and does not decrease a decoloration speed even after long coloration time by impressing waveforms of the potentials are alternately changed to body put same into coloring state natural potential that possesses decoloring state. CONSTITUTION: The electrochromic constituted providing composite viologen film formed adding electrically conductive powder high-polymer complex polystyrene sulfonic acid tetramethylene as an material 9 transparent electrode 10. 10 counter 12 respectively provided on glass substrate 11. A spacer 13 interposed between such substrates 11 constitute cell. An electrolyte soln. 14 contg. KCl sealed in writing voltage waveform shown figure impressed cell subjected test. As result, long-time at life executed without affecting response. COPYRIGHT: (C)1986,JPO&Japio
