    • In accordance with the invention, display systems have a view switch panel placed in front of displaying surface of a display to manipulate lights outputted thereby or incidence ambient lights. The view switch panel comprises a layer of reflective polarizer and a polarization steering layer comprising a layer of liquid crystal and two electrode layers sandwiching the layer of liquid crystal in between, and may further comprise a layer of second polarizer placed on the other side of the polarization steering layer than the layer of reflective polarizer. The view switch panel uses the polarization steering layer to steer polarization of pass-through lights, then direct the lights by reflection or transmission by the layer of reflective polarizer. Two display systems, dual view convertible display making displayed images selectively viewable from either side and mirror view display making selectively front surface either reflective or non-reflective, are described.
    • 根据本发明,显示系统具有放置在显示器的显示表面前面的视图开关面板,以操纵由此输出的光或入射环境光。 视图开关面板包括反射型偏振器层和包括一层液晶的两极电极层和夹在其间的液晶层的两个电极层的偏振转向层,并且还可包括位于第二偏振器的另一侧上的第二偏振器层 偏振转向层比反射偏振器层。 视图开关面板使用偏振转向层来引导通过光的偏振,然后通过反射偏振器层的反射或透射引导光。 描述了两个显示系统,双视图可转换显示器,其使从任一侧选择性地观看的显示图像和使得选择性地反射或不反射的前表面的镜视图显示器。
