    摘要: Disclosed herein are various embodiments related to luminescence-based reflective display pixels. In one embodiment, among others, a luminescent-based pixel includes a luminescent layer including luminophores distributed in a matrix. The luminescent layer is configured to receive light from an ambient environment through a first side of the luminescent layer and has an index of refraction that is higher than an index of refraction of the ambient environment. The luminescent- based pixel includes a mirror disposed on a second side of the luminescent layer that is opposite the first side of the luminescent layer. The luminescent-based pixel also includes a diffusive surface to randomize the direction of incident light.

    摘要: An illumination system (31) suitable for a liquid crystal display consisting of an edge-mounted light source (35) arranged at a corner or at one of the edges of a planar light guide (34). The design of the light guide allows the suppression of an undesirable ''bright line'' optical effect (19) visible at oblique angles to the light guide. Optical structures (37,38), which do not protrude from the light guide are provided on the first main surface of the light guide. This first main surface is arranged opposite to the second main surface (39) through which the light from the source is transmitted. The recessed design of the structures also avoids their deformation even when pressure is applied. The optical structures include a distribution of deflecting elements (37) consisting of recessed facets (40,41) of triangular cross section (fig 8) and a distribution of diffusing elements (38). Each of the diffusing elements is arranged in front of one of the deflecting elements as seen from the direction of the incident light (fig 6), and partially covers the corresponding deflecting element. The diffusing elements are also provided by recesses in the first main surface of the light guide (34).
    Each of the diffusing elements consists of a recess having an undulating ribbed surface (fig 7), such that the profile of the recess perpendicular to the direction of incident light (43) exhibits a wave-like form in the recess depth. The ribs run substantially parallel to the direction of incident light exhibiting a substantially uniform rectangular profile in that direction.
