摘要:
A method for changing self-description data of a functional device in a computing system. The method may include virtualizing the functional device to create a virtual functional device, and adding, changing, or removing information in the self-description information sent from a functional device as a part of virtualization of the device by a hypervisor. Changing the self-description data of the functional device occurs after the self-description data has left the functional device.
摘要:
A cutting tool assembly having a tool post capable of lateral movement along a work piece to be cut and an actuator with a tool tip. The actuator provides for control of the movement of the tool tip in an x-direction into and out of the work piece in order to make discontinuous microstructures in it. The machined work piece can be used to make microstructured articles such as films having non-adjacent lenslets.
摘要:
Optical films are disclosed that include a substantially transparent body having a first surface defined by a substrate portion and a structured surface disposed over the substrate portion opposite to the first surface. The structured surface includes a plurality of smaller pyramidal structures and a plurality of larger pyramidal structures interspersed with the plurality of smaller pyramidal structures. Each pyramidal structure has a base including at least two first sides disposed opposite to each other and at least two second sides disposed opposite to each other. Also disclosed are optical devices including such optical films.

Optical films are disclosed that include a body having a first surface, an axis and a structured surface including a plurality of pyramidal structures. Each pyramidal structure has a rounded tip and a base including at least two first sides disposed opposite to each other and at least two second sides disposed opposite to each other. Also disclosed are optical devices including such optical films.
摘要:
A scratch-resistant light directing film has a structured surface with first and second prism elements. The first prism elements are taller than the second prism elements and have blunt tips. The second prism elements are shorter and have sharp tips. The resulting film is scratch-resistant without substantially sacrificing gains in on-axis light.

Backlighting systems are disclosed, which include a lightguide with at least one light source optically connected to an edge of the lightguide for supplying light into its interior and a reflective cavity with at least one light source optically connected to the reflective cavity for supplying light into its interior. The reflective cavity may include a first reflector and a second reflector and at least one source may be disposed at an edge of the reflective cavity. Alternatively, the reflective cavity may include a back reflector portion and light sources may be disposed at the back reflector portion.
摘要:
The present disclosure is directed to backlighting systems, which include first and second lightguides, at least one light source optically connected to an edge of the first lightguide and at least one light source optically connected to an edge of the second lightguide for supplying light into their respective interiors. In the appropriate exemplary embodiments, the backlighting systems of the present disclosure include an extractor disposed at a surface of the second lightguide for diffuse extraction of light from the interior of the second lightguide. In such exemplary embodiments, at least a portion of the light supplied into the interior of the second lightguide and then diffusely extracted therefrom enters the interior of the first lightguide through a substantially optically clear surface. In some exemplary embodiments, the backlighting systems of the present disclosure include recycling enhancement structures, which may be attached to the first lightguide.
摘要:
An optical element, such as a lightguide or an optical film, is formed with a predetermined, programmed pattern of optical structures. The optical structures may be arranged to selectively correct for non-uniformities in the output a lightguide, or may be arranged to otherwise enhance the performance of a display.
摘要:
A backlight includes a lightguide, a light source disposed with respect to the lightguide to introduce light into the lightguide and a turning film. Optical structures are formed in one of an output surface and a back surface of the lightguide. The optical structures are arranged to extract light from the lightguide. A back reflector is disposed adjacent the back surface. The optical structures are formed to include a varying pattern arranged to mask non-uniformities in the output of the lightguide.
摘要:
A flexible light guide and a display system incorporating same are disclosed. The light guide includes a first flexible layer and a second flexible layer. Each flexible layer has a first major surface and a second major surface. The second major surface of the first flexible layer is in contact with the first major surface of the second flexible layer. The first major surface of the first flexible layer has a plurality of discrete light extractors capable of extracting light propagating in the light guide such that light is extracted uniformly over the entire first major surface of the first flexible layer.
