摘要： This disclosure provides systems, methods, and apparatus for providing illumination using a light-turning stack having diffractive light-turning features to eject light out of the light-turning stack. In one aspect, light ejected from the light-turning stack may be applied to illuminate a display. The light-turning stack includes a light-guiding layer having a surface on which the diffractive light-turning features are disposed. A planarization layer having a refractive index different than a refractive index of the light-guiding layer directly contacts the diffractive light-turning features and has a planar surface opposite the light-turning features. The light-guiding layer can also have a planar surface opposite the light-turning features. Both these planar surfaces, on opposite sides of the light turning stack, facilitate the integration of the light-guiding layer with other layers of material, including functional layers.

摘要： A light guide device includes a light guide body and two or more pluralities of spaced-apart slits. The slits are formed by undercuts in the light guide body. Sidewalls of the slits form facets that redirect light impinging on the facets. In some embodiments, the light guide body is attached to a light source. The light source emits light that is injected into the light guide body and the slits redirect the light out of the light guide body and towards a desired target. In some embodiments, the target is a display and a first plurality of slits directs light from the light source across the light guide body and over the face of the display. A second plurality of slits then directs light out of the light guide body and towards the display.

摘要： This disclosure provides systems, methods and apparatus for a projected capacitive touch (PCT) sensor that may include thin sensor electrodes coated with additional layers to form an optical cavity that reinforces a wavelength range or color of incident light. The sensor electrodes and a cover glass border and/or decorations may be fabricated simultaneously. In some implementations, the thickness of the optical cavity will be selected such that the “color” of reflected light is black. The sensor electrodes may not be noticeable to a human observer. However, in some other implementations, the thickness of the optical cavity may be selected such that the sensor electrodes and/or the decorative portions will have another color. Routing wires of the touch sensor may be shielded by a grounded conductive layer in the border.

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a surface, such as an edge, into which light is injected. The surface is treated to create a diffusive interface with a light source. For example, the surface may be subjected to abrasion to form a frosted surface that acts as the diffusive interface, or a diffusive structure may be attached to the edge, with the attached diffusive structure functioning as the diffusive interface. The diffusive interface diffuses light entering into the light guide, and can thereby increase the uniformity of light propagating within the light guide. The light guide may be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： Disclosed are apparatus and methods for illuminating a display. In certain embodiments, the illumination apparatus includes a light guide that receives light from a light generator along an edge of the light guide and directs the received light via light extractor features (e.g., grooves) towards a display. The light guide includes at least two sets of light extractor features that are rotated with respect to each other so as to reduce a shadowing effect on the display when the display is viewed from within a specific range of viewing angles. In further embodiments, the spacing or orientation of each or one of the extractor feature sets may also be adjusted so that other visual artifacts, such as a Moiré effect, are reduced.

摘要： Disclosed are various embodiments of a holographic based optical touchscreen and methods of configuring such devices. In certain embodiments, a touchscreen assembly can include a holographic layer configured to receive incident light and turn it into a selected direction to be transmitted through a light guide. The holographic layer can be configured to accept incident light within an acceptance range and so that the selected direction is within some range of directions so as to allow determination of incidence location based on detection of the turned light. A light source can be provided so that light from the source scatters from an object such as a fingertip near the holographic layer and becomes the incident light. Thus the determined incidence location can represent presence of the fingertip at or near the incidence location, thereby providing touchscreen functionality. Non-limiting examples of design considerations and variations are disclosed.
