Taiwanese scientists have created a LCD display that senses where its viewer is and automatically adjusts itself to provide better images:
Their technique prevents users from seeing a blurred or distorted image when viewing a liquid crystal display (LCD) from an angle instead of straight on.
The Taiwanese researchers have developed a prototype display connected to a miniature camera that tracks the location of a viewer. Software then calculates how to adjust the liquid crystals within the display to produce the clearest possible image.
"Viewing angle is an inherent, fundamental problem for the LCD because of its working principle," says Wayne Cheng, who developed the screen with colleague Chih-Nan Wu at the Photonics and Display Institute, National Chiao Tung University in Taiwan.
