Kent is a world leader in research and development of technology for the manufacturing of liquid crystal displays, LCDs, bistables, and cholesterics. These devices are used in industrial, consumer, medical, user information, and allow their use in higher operational temeperature ranges than other bistable technologies. These displays are manufactured in reflective mode, but given their high contrast, they are easily readable in low light environments. In addition, they offer excellent viewing angles (178º horizontal and vertical), and their very low power consumption may keep the image up to 10 years.
