    Abstract: A stretchable sheet-form electronic display having a generally rectangular shape with four edges, a thickness of less than 1.5 mm, and a longer dimension of at least 100 mm. The stretchable sheet-form electronic display includes an elastic substrate sheet comprising a thin layer of an optically transmissive material having a relatively high elastic range, a grid of flexible connecting members and a two-dimensional array of at least 100,000 digitally addressable solid-state light emitting devices such as micro OLEDs or LEDs. At least some of the solid-state light emitting devices may be arranged into light emitting clusters and directly or indirectly mounted to a plurality of support pads. The solid-state light emitting devices within the clusters may be configured for emitting light in different colors such as blue, red, and green.

    Abstract: A light emitting module including: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole; and a light source disposed in the light source placement part. In the schematic top view: the light adjusting hole is not positioned on a first straight line connecting (i) a center of the light source and (ii) a point in the sectioning groove that is farthest from the center of the light source, and a first lateral face of the light adjusting hole has a first region, and a line normal to the first region is oblique to a second straight line connecting (i) the center of the light source and (ii) a point in the sectioning groove that is closest to the center of the light source.

    Abstract: An electronic display panel having a generally rectangular shape with rounded corners, a thickness of less than 1.5 mm, a longer dimension of at least 100 mm, a support substrate, a rigid heat-conductive substrate, a transparent or translucent area, a two-dimensional array of at least 1,000,000 digitally addressable solid-state light emitting devices arranged in rows and columns and each having a size from 1 μm to 300 μm, and a grid of connecting members defining a plurality of grid connection nodes and an area-distributed plurality of openings configured for providing a partial view through the panel. The support substrate may incorporate a thin layer of an optically transmissive material having a substantially uniform thickness and a Young's modulus of at least 1 GPa. At least some of the solid-state light emitting devices may be arranged into light emitting clusters and directly or indirectly mounted to a plurality of support pads. The solid-state light emitting devices within the clusters may be configured for emitting light in different colors such as blue, red, and green.

    Abstract: A light emitting device includes a base having a light reflecting surface and having a first side on which the light reflecting surface is provided, light sources mounted on the first side, and a half mirror disposed opposite to the base to reflect a part of incident light and to transmit another part of the incident light. Each of the light sources includes a reflecting layer on an upper surface of each of the light sources. The half mirror has an oblique reflectance with respect to wavelengths of light emitted from the light sources in a case where the light travels obliquely toward the half mirror. The half mirror has a perpendicular reflectance with respect to the wavelengths in a case where the light travels perpendicularly toward the half mirror. The oblique reflectance is smaller than the perpendicular reflectance.

    Abstract: A light emitting module includes: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole that, in a schematic top view, is located between the sectioning groove and the light source placement part; and a light source disposed in the light source placement part. A refractive index of an inside of the light adjusting hole is lower than a refractive index of the light guide member. In the schematic top view, the light adjusting hole is positioned to intersect with a first straight line connecting a center of the light source and a farthest point in the sectioning groove, the farthest point being farthest from the center of the light source.
