Abstract
Aspects of the invention can provide an image display apparatus for displaying an image by modulating light from a light source based on display image data. The apparatus can include a first light modulator device can modulate light from the light source, a second light modulator device that can modulate the light from the first light modulator device, and a polarization compensation system disposed between the first light modulator device and the second light modulator device for compensating a polarization state of light.
Claims11
An image display apparatus that displays an image by modulating light from a light source based on display image data, the apparatus comprising:
- a first light modulator device that modulates light from the light source, the first light modulator device including at least one light-exiting side polarizer;
- a second light modulator device that modulates the light from the first light modulator device;
- and
- a polarization compensation system disposed between the first light modulator device and the second light modulator device, the polarization compensation system changes a polarization state of light to return to nearly the same state as a polarization state of light after exiting the at least one-exiting side polarizer.
A polarization compensation system being an optical system changes a polarization state of light to return to nearly the same state as a polarization state of that after exiting at least one light-exiting side polarizer and that is disposed between two light modulator devices optically and serially arranged.
