摘要：
Jones matrix method was used to optimize the twisted nematic liquid crystal cell parameters for reflective direct-view and projection displays. Twist angles ranging from 0 to 90 degrees were investigated. From these analyses, two operation modes are found to have particularly important applications. The mixed-mode 90 degrees twisted nematic cell exhibits an excellent contrast ratio for normally white direct-view and projection displays whereas the improved 45 degrees twisted nematic cell shows an impressive light efficiency for normally black projection display.
