ELECTROCHROMIC FILTER AND FABRICATING METHOD THEREOF, AND AN APPARATUS FOR FORMING AN OPTICAL IMAGE BY USING THE SAME, PARTICULARLY FOR ENABLING IMAGE CAPTURE PROCESS OF WIDER DENSITY RANGE

摘要

PURPOSE: An electrochromic filter and fabricating method thereof, and an apparatus for forming an optical image by using the same are provided to control an electrochromic filter based on pixel unit by dividing transparent electrodes into plural pixels.;CONSTITUTION: An electrochomic filter(100) includes a first transparent electrode(120), an inorganic electrochromic thin film(130) and a second transparent electrode(160). The first transparent electrode is formed on a lower substrate, and the inorganic electrochromic thin film grows on the first transparent electrode. The second transparent electrode grows on the inorganic electrochromic thin film. The first and second transparent electrodes are divided into plural pixels.;COPYRIGHT KIPO 2010
