摘要： This disclosure provides systems, methods and apparatus for increasing the efficiency of frontlight systems using thin waveguides (410). In one aspect, a narrowing reflective conduit (460) can be used to condense light from a light source (430) which is thicker than the waveguide (410), and inject it into the waveguide (410). A phosphor strip (470) at the exit aperture of the narrowing reflective conduit can inject light with a diffuse directional profile independent of the directional profile of light within the narrowing reflective conduit (460).

摘要： This disclosure provides systems, methods and apparatus related to an illumination system for a display device. In one aspect, the illumination system includes a light guide (902) having a view region (914), which directly overlies display elements of a display, and a ledge region (916) between the view region and a light source (904) that injects light into the light guide. The ledge region is coated with an at least partially non-transmissive layer (922). The layer can be at least partially absorptive and/or at least partially reflective. In some implementations, the layer can include microstructures configured to turn steep-angle light such that it is redirected across the light guide at a shallower angle. In some implementations, the boundary between the ledge region and the view region of the light guide can have a nonlinear shape.

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 includes a light turning film (128) over an optically transmissive supporting layer (129). In some implementations, the light turning film may be formed of a material deposited in the liquid state. In some implementations, the light turning film may be formed of a photodefinable material, which may be glass, such a spin-on glass, or may be a polymer. In some other implementations, the glass is not photodefinable. The light turning film may have indentations (131) that define light turning features and a protective layer may be formed over those indentations. The protective layer may also be formed of a glass material, such as spin-on glass. The light turning features in the light guide film may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus for an illumination system. In one aspect, the illumination system is a light guide (101) that includes spaced-apart regions of medium (205a, 205b, 205c and 205d) containing diffractive features. For example, the medium may include holographic medium having holograms that are configured to redirect light (140), propagating through the light guide (101), out of the light guide (101). The spaces (209a, 209b, 209c and 209d) between the spaced-apart regions of media (205a, 205b, 205c and 205d) may be filled with a material having a lower refractive index than the light guide, thereby functioning as a reflective cladding in those spaces.

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 light input edge into which light is injected and transverse edges transverse to the light input edge. The transverse edges are smooth and act as specular reflectors. The light input edge is rough and provides a diffusive interface. The light emitters are adjacent and centered along the light input edge, with the pitch of the light emitters being about ?L, where ΔL is the distance between the transverse edges divided by the number of light emitters. The diffusive light input edge can diffuse light entering into the light guide, and the transverse edges can reflect light with a low level of artifacts and the reflections also act as virtual light sources to facilitate a highly uniform distribution of light within the light guide. The light guide can be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light can be applied to illuminate a display.

摘要： This disclosure provides systems, methods, and apparatuses for illumination using illumination systems having a light guide (1000). A light source (1010) is configured to inject light into a light input edge (1030a) of the light guide. The light guide is configured to recirculate the injected light therein such that the light passes back and forth across the light guide one or more times. The light guide includes light-turning features (1040) that extract light out of the light guide. To promote light recirculation, the light-turning features have a per- pass light extraction efficiency of about 50% or less and one or more edges (1030b) of the light guide may be reflective. The light extracted out of the light guide by the light-turning features may be used to illuminate a display.
摘要翻译：本公开提供了使用具有光导（1000）的照明系统进行照明的系统，方法和装置。光源（1010）被配置为将光注入到光导的光输入边缘（1030a）中。光导被配置为使注入的光在其中再循环，使得光穿过光导来回穿过一次或多次。光导包括从光导中提取光的光转动特征（1040）。为了促进光再循环，光转向特征具有约50％以下的过滤光提取效率，并且光导的一个或多个边缘（1030b）可以是反射性的。通过光转动特征从光导中提取的光可以用于照亮显示器。

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 (907a, 907b) and a cover glass border and/or decorations (1305) 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 (907a, 907b) 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 (907a, 907b) and/or the decorative portions (1305) will have another color. Routing wires (1120a) of the touch sensor may be shielded by a grounded conductive layer in the border.
摘要翻译：本公开提供了用于投影电容式触摸（PCT）传感器的系统，方法和装置，其可以包括涂覆有附加层的薄传感器电极，以形成加强入射光的波长范围或颜色的光学腔。传感器电极（907a，907b）和盖玻璃边框和/或装饰物（1305）可以同时制造。在一些实施方案中，光腔的厚度将被选择为使得反射光的“颜色”为黑色。传感器电极（907a，907b）可能不会对人类观察者显着。然而，在一些其它实现中，可以选择光腔的厚度，使得传感器电极（907a，907b）和/或装饰部分（1305）将具有另一种颜色。触摸传感器的布线（1120a）可以被边界中的接地导电层屏蔽。

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, a passivation layer is attached to the light guide of an illumination device. The passivation layer may be an optically transparent moisture barrier and may have a thickness and refractive index which allows it to function as an anti-reflective coating. The passivation layer may protect moisture-sensitive underlying features, such as metallized light turning features that may be present in the light guide. The light turning features may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus for increasing the uniformity of illumination provided by frontlight systems (250) using multiple discrete light sources (230). In one aspect, a phosphor material (236) can be disposed between the discrete light sources and a light-turning waveguide (210), so that at least some of the light emitted by the discrete light sources is absorbed and re-emitted by the phosphor material. The light re- emitted by the phosphor material can have a more diffuse directional profile than the light emitted by the discrete light sources, and injecting this more diffuse light into the waveguide can reduce optical effects which provide non-uniform illumination across the waveguide.
