Abstract
Twisted nematic (TN) liquid crystal display (LCD) is optimized for transflective liquid crystal displays. This new configuration does not separate the pixel into two sub-pixels of transmissive and reflective mode. Each pixel is partially transmissive and reflective with the help of a semi transparent mirror. The electro-optical characteristics in the transmissive mode and reflective mode match each other, which indicate that the transmissive and reflective functions can be controlled using the same voltage in a transflective LCD. TN LCD configuration exhibits a high contrast ratio, wide viewing angles, fast response time, and suitable for high quality transflective thin film transistor (TFT) LCDs.
