Abstract

A patterned light-dimming glass and a preparation method therefor. The light-dimming glass comprises two oppositely disposed transmitting conductive substrates that are packaged to form a regulating area (6); each of the two transmitting conductive substrates comprises a substrate (1) and an electrode layer (2) installed on a surface opposite to the substrate (1); and at least one of the two electrode layers (2) is an electrode layer (2) having a pattern. When voltage is not applied to the transmitting conductive substrates, the light-dimming glass is transparent, and the pattern of the electrode layer (2) is displayed. The method for preparing the electrode layer (2) having a pattern comprises the steps of: preparing a whole electrode layer (2′) on the substrate (1); coating a photoetching glue layer (3′) on the whole electrode layer (2′); preparing a photoetching plate (4) which has a pattern, and covering the the photoetching plate (4) over photoetching glue layer (3′); exposing; developing; postbaking; and corroding the electrode layer (2′) which is not covered by the photoetching glue layer (3′), thus obtaining the electrode layer (2) having a pattern. By using said method to prepare the electrode layer (2), a pattern having an accuracy which achieves micron level may be prepared.
