    • A method for forming a vehicle window assembly includes applying a band of an opaque ceramic enamel material to a predetermined peripheral portion of a sheet of relatively flat glass, and heating the glass to a prefire temperature to fuse the opaque material to the glass. An electrically conductive material is applied to the band in a predetermined pattern to form a pair of bus bars typically along the top and bottom edges of the sheet of glass. The glass is again heated to fire the bus bar material and soften the glass for bending into a desired window shape. A mask is applied to the bus bars for later connection of electrical leads and the sheet of glass is washed prior to the next operation. An electrically conductive film is applied to the second surface of the sheet of glass and electrically connected to the bus bars. The sheet of glass is laminated to a sheet of plastic material which covers the electrically conductive film and, typically, the plastic sheet is laminated to a second sheet of glass which has been preformed, i.e., bent, to conform to the first sheet. Electrical leads are attached to the bus bars to complete the window assembly. The electrically conducting film and glass sheet composition and thickness are chosen to maximize for the window assembly the desired performance characteristics of resistance, transmission, reflection and color-all of which are mutually interactive.
    • 一种用于形成车窗组件的方法包括将不透明陶瓷搪瓷材料的带施加到相对平坦的玻璃板的预定周边部分,并将玻璃加热到预热温度以将不透明材料熔合到玻璃。 以预定图案将导电材料施加到带上以形成通常沿着玻璃板的顶部和底部边缘的一对汇流条。 玻璃再次被加热以对母线材料起火并使玻璃软化以弯曲成所需的窗口形状。 将母板施加到汇流条上以便以后连接电线,并且在下一次操作之前冲洗玻璃片。 将导电膜施加到玻璃板的第二表面并电连接到汇流条。 玻璃片被层压到覆盖导电膜的塑料材料片上,并且通常将塑料片层压到已经预成型,即弯曲的第二片玻璃上,以符合第一片。 电气引线连接到母线上以完成窗组件。 选择导电膜和玻璃板组合物和厚度以使窗组件最大化电阻,透射,反射和颜色的所需性能特征 - 所有这些性质特征是相互交互的。
