Abstract:
This disclosure provides systems, methods and apparatus for reducing ambient light reflections from a surface of a display device in a power efficient manner. The display device includes a reflecting circular polarizer (RCP) and an absorbing circular polarizer (ACP) having the same polarity. The RCP provides light recycling functionality, while the ACP provides ambient light reflection suppression. In some implementations, the light generated by the display device is polarized by the RCP before it is incident on the ACP, which is located at the front of the display device. Because the polarities of the RCP and the ACP are the same, the ACP substantially passes all of the incident polarized light towards the front of the display device.
