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 providing stacks of optical films that may be used to provide increased on-axis display brightness. In one aspect, an apparatus or system may be provided that includes a light source, a first optical film having triangular cross-section, prismatic light-turning structures, and a second optical film having trapezoidal cross-section, prismatic light-turning structures. The first optical film may be interposed between the light source and the second optical film. In further aspects, a third optical film, similar to the first optical film, may be interposed between the light source and the first optical film. In yet further aspects, one or more additional optical films, similar to the second optical film, may be positioned in the stack such that the second optical film is between the first optical film and the additional optical film(s).

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 for image displays incorporating color selective reflectors. The display apparatus includes a substantially monochromatic light source capable of outputting a substantially monochromatic light. The display apparatus incorporates a color conversion material capable of converting at least a portion of the substantially monochromatic light output by the substantially monochromatic light source into light associated with at least one subfield color. The display device also includes a plurality of pixels, each pixel including at least two color-selective reflectors, each color-selective reflector being capable of passing light of a respective subfield color and reflecting light associated with at least two other subfield colors.

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.

Abstract: A transport device for securing and transporting motorcycles or other similar vehicles from one location to another including a base plate member attachable to the floor of a hauling vehicle, at least one stationary plate member secured to the base plate member, a movable plate member adaptable for movement relative to the at least one stationary member and being selectively positionable so as to capture the front wheel of a motorcycle or other vehicle therebetween, and a mechanism for selectively moving the movable plate member relative to the at least one stationary plate member so as to secure and hold a motorcycle or other vehicle in an upright stable position. The capturing or clamping force exerted against the front wheel can be varied and adjusted depending upon the size and weight of the motorcycle or other vehicle.

Abstract: A method includes exposing an alignment material to an interference pattern to cause a chemical reaction in the alignment material and exposing the alignment material to a liquid crystal, where the liquid crystal aligns relative to the alignment material based on the interference pattern.
