Abstract
An accurate description of spectral and angular optical transmission is needed to characterize and optimize a liquid crystal display. Actual FLC display prototypes have been modelled from their director profiles. When broad spectrum backlights, color filters, and real polarizers are used, and several hundreds of oblique incidences are calculated, the running time may reach unpractical limits. A complete calculation process with reasonable running time is described. The results are compared to experimental measurements.
