TFT-LCD用彩色滤光片

COLOR FILTER FOR TFT-LCD

彩色滤光片作为液晶显示器件的关键组件,其性能直接影响显示器的对比度、亮度、视角乃至画面质量。本文阐述LCD用彩色滤光片的结构、特性和制取方法,着重介绍目前最常用的制取彩色滤光片的颜料分散法。彩色滤光片产业属于技术密集型产业,只有掌握相关的技术知识,打破国外在颜料领域的垄断,拥有自主知识产权,才能带动国内整个行业的发展。

As one of the most important elements, the property of the color filter directly influences on the chromatic quality, and the contrast ratio, brightness and viewing angle. This paper describes color filter for TFT-LCD, and generalizes the structure, property and the manufacturing methods in details, at present pigment-dispersed method is the most common one.The color filter field is a technology-intensive industry, only by mastering the correlative technologies, breaking the oversea monopoly in the field of photoresists and pigments for LCD CF and owning the independent intellectual assets, it can develop TFT-LCD industry in China and to lead the developing of the whole LCD industry.
