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.
Claims18
A liquid crystal display comprising:
- a luminaire;
- an iodine-type input polarizer for polarizing light from the luminaire;
- a liquid crystal module for receiving polarized light from the iodine-type input polarizer;
- and
- a high temperature type output polarizer for receiving light from the liquid crystal module.
