摘要:
A display system includes a display panel configured to emit a polarized image light having a first polarization state and at least one emission spectrum having a full width at half maxima (FWHM). The display system includes a reflective polarizer configured to receive and reflect the polarized image light as a first reflected polarized image light. For a first light incident at a first predetermined angle, the reflective polarizer has an average reflectance of greater than about 60% across the at least one emission spectrum for the first polarization state, a transmittance of at least about 50% for at least wavelength outside the FWHM of the at least one emission spectrum for the first polarization state, and an average total transmittance of greater than about 70% across a visible wavelength range including the FWHM of the at least one emission spectrum for an orthogonal second polarization state.
