Summary

A new retarder film was developed which shows a reversible retardation change with temperature to reduce the loss of contrast of film-compensated STN-mode LCDs with increasing temperature. The film consists of polycarbonate blended with a liquid-crystalline silicone. The improvement of the LCD's contrast over a wide temperature range and the stability of the film satisfy the requirements for car equipment and other mobile applications.
