A Double-Layered Super-Twisted Nematic (D-STN) LCD was developed for application in an automotive information display requiring the presentation of both character and symbolic information.Cell parameters were optimized to minimize the background transmission and to widen the operating temperature range.A contrast ratio exceeding 50:1 was achieved for temperature range of -30°C to 80°C. The viewing angle was found to be comparable to a conventional Twisted Nematic (TN) LCD multiplexed with a 1/2 duty cycle. Electro-optical properties, such as temperature dependence of the driving voltage and the response time have also been described.
