Visibility of transmissive liquid crystal displays under dynamic lighting conditions

摘要: Liquid crystal displays maintain superior contrast under bright sunlight conditions compared with cathode-ray tube displays. This attribute, along reduced weight, volume, and power requirements, make liquid especially desirable for use in vehicular applications. The present experiment was designed to determine the luminance requirements transmissive viewed a wide range of lighting typical many environments. Both ambient illumination incident on display surface forward-field-of-view adaptation were parametrically manipulated. visual task involved speeded spatial discrimination responses detection gap modified Landolt-C acuity target. results indicate that worst tested, approximately 180 cd/m2 yielded asymptotic performance. have been incorporated into predictive performance model tasks, which describes data well represents first step toward device-independent visibility.
