ABSTRACT:
A liquid crystal display for use in applications where direct exposure to sunlight creates a thermal gradient from the front of the display to the back of the display uses a high efficiency iodine-type input polarizer and a high temperature type output polarizer. The output polarizer has a higher temperature rating than the input polarizer, so that the thermal gradient does not degrade display performance.
