本发明描述制造电致变色窗之方法。制造一电致变色器件以实质上覆盖一玻璃薄片(举例而言，浮法玻璃)，且基于该器件中之一或多个低缺陷区域界定一切割图案，自该区域切割一或多个电致变色窗板。可在切割该等窗板之前或之后加上激光刻划及/或汇流条。亦可在自该玻璃薄片切割该等电致变色窗板之前或之后运行边缘删除。绝缘玻璃单元(IGU)由该等电致变色窗板制造且视情况强化该IGU之该等窗板之一或多者。

Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.
