Claim of US Patent No. 10,143,094

10. An optical member for multi-panel display device, comprising:a plurality of light conduits of a first refractive index, the plurality of light conduits at least including a first light conduit and a second light conduit, each light conduit of the plurality of light conduits corresponding to one pixel of a display device, each light conduit comprising an input surface receiving lights from a corresponding pixel and an output surface transmitting the received light, the input surface having an area smaller than the output surface, a subset of the light conduits having the output surface shifted towards junction lines adjoining a plurality of individual display devices, relative to the input surface of the subset of the light conduits to transmit light over non-active areas of the display devices, each light conduit of the subset of light conduits comprising:
a first portion extending in a first direction perpendicularly to the input surface,
a second portion coupled to the first portion, the second portion extending in a second direction obliquely with respect to the first portion, the first portion of the first light conduit and the second portion of the first light conduit forming a first angle, and the first portion of the second light conduit and the second portion of the second light conduit forming a second angle different than the first angle, and
a third portion coupled to the second portion, the third portion extending in the first direction; and
a resin support, the resin support disposed at least over a non-display area of the plurality of display devices, the resin support having a first surface extending in the first direction, and a second surface extending in the second direction, the resin support having a refractive index lower than the first refractive index.
