Abstract: This disclosure provides devices, apparatuses and methods of providing an optical filter with quantum dot films for converting a first wavelength of light to a second wavelength of light. The optical filter includes a plurality of high refractive index layers and a plurality of low refractive index layers alternatingly disposed between the high refractive index layers. Quantum dots are dispersed in either the high refractive index layers or the low refractive index layers. In some implementations, the quantum dots are capable of absorbing blue light and emitting green light. Thus, the optical filter can be part of a red-green-blue lighting device that includes a first blue LED optically coupled with the optical filter to produce green light, a red LED and a second blue LED.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for enhancing display viewability in high ambient conditions without excessive increase in power consumption. In one aspect, a controller associated with the display device can be configured to obtain an indication of ambient light conditions from an ambient light sensor or from a host device hosting the display device. Upon receiving an image frame, the controller can derive a set of color subfields and determine a bit-depth value for each color subfield based on the obtained indication of current ambient light conditions and mapping data which maps ranges of ambient light to respective bit-depth values on a color subfield by color subfield basis. The controller can then generate a number of subframes for each color subfield based on the respective determined bit-depth value and cause the generated subframes to be displayed.

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.
