研制了一用于彩色液晶显示的高分子聚酰亚胺，并对所用染料进行筛选，探索了其涂膜和光刻制备工艺，对其分光特性测试表明，所制备的三基色膜可用于颜色传感器，液晶显示等电子器件。 A high molecular polyimide for color liquid crystal display was developed. The dyes used were screened and their coating films and photolithographic process were explored. The spectroscopic properties of the films showed that the prepared three-color films could be used in color Sensors, LCD and other electronic devices.
