New Front Surface Film for Improving the Viewing-Angle Properties of TN-Mode TFT-LCDs

摘要

We have succeeded in the development of a new front surface film, it has the function of improving the viewing-angle properties (especially, improvement of gray scale inversion in downside direction) of TN-mode TFT-LCDs, in addition to the conventional function of the protection of polarizer and the glare prevention under bright room surrounding . The excellent viewing-angle properties have been realized in combing this new front surface film with the optical compensation film for TN-mode (Wide-View Film, for short WV Film). According to the proposal of this method, it has been expected to apply TN-mode to large-size LCD monitors and LCD TVs hereafter.
