TN (twisted nematic) film based LCD displays are the most common screen technology used in laptops and monitors today, as they are cheaper to make. But, these displays suffer from limited viewing angles and inferior color reproduction. The reason behind these poor qualities of TN based displays is retardation of light inside the LCD display.
Toray Industry claims that they have solved this problem and have developed a new coating material that is designed to optimize and cut down the process of retarder inside an LCD panel. The new material reduce stress variations caused by film expansion and contraction on components attached to a glass substrate in LCD. The reduction in variations results in better viewing angle and color reproduction.
 The new coating material forms an alignment film few microns thick and it achieves viewing properties equal or higher than VA (vertical alignment) film based LCD screen. Toray Industry will start commercial production of the coating material in 2010. Though this technology won’t bring the TN film based LCDs anywhere near the color reproduction and viewing angles offered by IPS (in-plane switching) based LCDs, but it will definitely improve the image quality on TN film based LCD displays.
