SINCE THE MID-1990S, CATHODE RAY TUBES HAVE BEEN REPLACED BY LC DISPLAYS
These displays have become not only thinner but also larger, with faster switching times, sharper images and brighter colors.
Mobile electronic devices, elegant televisions and computers would not be possible without liquid crystals. They can modulate a backlight with such precision that the colors and pictures presented on the screen have a truly impressive effect. “In developing and producing these displays,” says Chung-Kuang Wei, “the most important goal is to create the perfect balance between performance and cost.”
Dr. Wei, a physicist, is Associate Vice President of the technology center of Innolux, which is located in the southern Taiwanese city of Tainan. Innolux is the third-largest manufacturer of LC displays.
The company’s approximately 93,000 employees provide today’s electronics with a face, one that is based on liquid crystal technology. The fact that materials could have a liquid crystal state was discovered more than 100 years ago. In this state, materials function as optical switches when an electric field is applied: light on, light off. A standard ultra high definition television — UHDTV — has around eight million of these switches. Due to its more than 4,000 columns and over 2,000 rows, UHDTV is also known as 4K2K.
