Requirements for large‐sized high‐resolution TFT‐LCDs

A 22-in. prototype TFT-LCD with a resolution of 200 pixels per inch and wide-viewing-angle capability has been developed and its requirements in terms of screen quality and technology will be discussed. An in-plane-switching mode with dual-domain structure, post-spacers, and high-resolution process were implemented to achieve superior front-of-screen quality. And, also, in order to improve reliability and productivity, we developed a new injection method for liquid crystals which enabled us to eliminate injection holes.
