ELECTROLYTIC DISPLAY DEVICE EMPLOYING METAL ION CATALYSIS |
摘要 |
An electrolytic display device, specifically an electrochromic display based on viologen, employs metal ions in solution to catalyse the reduction of display material at the display electrodes. The metal ions are deposited faster than the display material and subsequently chemically reduce this material. Thallium (I) as the metal catalyst in combination with an oxy-anion of phosphorus accelerates the display reaction without causing undesired precipitation from the solution. Cadmium (II) in combination with sulphate anions is also an effective catalyst. Either a greater amount of display material may be deposited than without the catalyst or the same amount deposited in a shorter time. |
