Abstract
A head-up display (HUD) compatible with polarized sunglasses is disclosed. The HUD includes a thin-film transistor liquid crystal display (TFT-LCD), an active polarization modulator, and a wavelength filter. The active polarization modulator and the wavelength filter are optically bonded to the TFT-LCD. The active polarization modulator is configured to modulate a polarization from the TFT-LCD. The wavelength filter is configured to increase a sunlight resistance of the TFT-LCD.
Claims20
A head-up display (HUD), comprising:
- a thin-film transistor liquid crystal display (TFT-LCD);
- an active polarization modulator;
- and
- a wavelength filter;
- wherein the active polarization modulator and the wavelength filter are optically bonded to the TFT-LCD.
A system for a HUD, comprising:
- an active polarization modulator front plate;
- a coating adjacent to the active polarization modulator front plate;
- an active polarization modulator rear plate adjacent to the active polarization modulator front plate;
- a first reflective polarizer adjacent to the active polarization modulator rear plate;
- an LCD front plate adjacent to the first reflective polarizer;
- an LCD rear plate adjacent to the LCD front plate;
- and
- a second reflective polarizer adjacent to the LCD rear plate.
A display device compatible with polarized sunglasses, comprising:
- a display for displaying information, the display includes components arranged to reduce internal surfaces;
- and
- a half-wave plate coupled to the display and arranged to receive S-polarized light from the display, wherein the half-wave plate outputs the P-polarized light;
- and
- wherein the components reduce a ghost image on the display.
