Aspects of the present disclosure involve a transparent structure. The structure may include at least one light source, a transparent light-carrying guide layer optically coupled with the at least one light source. The structure may include refractive layers where a light absorbing feature is operably associated with the light-carrying guide layer to absorb any light not internally reflected in the light guide layer, at least adjacent the light source.

Wide-area solid-state illumination system, including one or more linear arrays of compact solid-state light sources, such as LEDs, an optical waveguide, and a light distributing grid panel. The optical waveguide comprises a thin sheet of an optically transmissive material which is optically coupled to the plurality of compact solid-state light sources and configured to distribute light from a first broad-area surface and an opposing second broad-area surface. A light extraction pattern is formed in the first broad-area surface and defines a plurality of light extraction areas alternating with separation areas. The light distributing grid panel comprises a plurality of transverse walls defining a plurality of openings configured for transmitting light and is positioned parallel to the thin sheet of an optically transmissive material such that at least one of the plurality of light extraction areas is disposed in registration with one of the plurality of openings and at least one of the separation areas is disposed in registration with one of the plurality of transverse walls.

A liquid crystal display is configured such that a composite layer thereof is transparent to incident light in one voltage condition (e.g., in the absence of an applied voltage) and scatters incident light out of the display in another voltage condition (e.g., when a voltage is applied). The liquid crystal display does not need polarizers or color filters.

An electrodeless organic light-emitting device (10) and LCD systems using same are disclosed. The electrodeless organic light-emitting device (10) includes an organic light-emitting structure (200) with at least one organic light-emitting layer (250), and an illuminator (100) operably disposed to illuminate the organic light-emitting structure (200) with redirected light (114D). The redirected light (114D) causes the one or more organic light-emitting layers (250) to emit light (254), which constitutes the illumination from the organic light-emitting device (10). An LCD system includes the electrodeless organic light-emitting device (10) operably arranged relative to an LCD panel to receive the illumination (254). The organic light-emitting layer (250) can be segmented, with each segment emitting a primary color of light. The organic light-emitting layer segments are aligned with the cells of the LCD panel to define pixels for forming a display image. The LCD system can be configured to have a non-black background color when in the “off” state. Methods of forming illumination and display light are also disclosed.

The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide. In so doing, the solution presented herein increases the amount of light available for light communications. Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.

An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source; the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.
