Abstract:
1. A display apparatus, comprising: a display module having a plurality of pixel regions arranged in an array, a liquid crystal display panel and a backlight module, wherein the liquid crystal display panel is disposed on a surface of the backlight module and includes a first substrate, a second substrate and a liquid crystal layer sandwiched by the first substrate and the second substrate, wherein each of the pixel regions has a first sub-pixel region, a second sub-pixel region and a third sub-pixel region, and light emitted from the backlight module passes through the first sub-pixel regions, the second sub-pixel regions and the third sub-pixel regions, respectively, so as to provide a first light with a first wavelength, a second light with a second wavelength and a third light with a third wavelength; a polarization controller configured on a display surface of the display module and having a plurality of control regions, wherein each of the control regions corresponds to one of the first sub-pixel regions, the second sub-pixel regions and the third sub-pixel regions, the control regions control polarizations of the first light, the second light and the third light passing though the control regions, and each of the first light, the second light and the third light exhibits two polarization components along two orthogonal directions after passing through the control regions; and a compensator configured on a side of the polarization controller away form the display surface and having a plurality of first compensating regions corresponding to the first sub-pixel regions, a plurality of second compensating regions corresponding to the second sub-pixel regions and a plurality of third compensating regions corresponding to the third sub-pixel regions, wherein the polarization components of the first light, the second light and the third light pass through the compensator, compensations of phase retardation respectively generated by the first compensating regions, the second compensating regions and the third compensating regions are different from one another so that different phase retardation due to lights with different wavelengths passing through the polarization controller can be eliminated.
