Abstract: A method for manufacturing a light-emitting module includes a step of providing a bonded board including a board including, on a first surface, a circuit pattern and wiring pads that are continuous with the circuit pattern and each have bottomed holes and light-emitting segments connected on a second surface of the board with an adhesive sheet interposed therebetween and including an array of light-emitting devices; a step of supplying electrically conductive paste inside the bottomed holes and on portions of the surface of the wiring pad around the bottomed holes through openings of a mask; and a step of performing thermal compression to harden the electrically conductive paste such that the thickness of the electrically conductive paste on the portions of the surface of the wiring pad is smaller than the electrically conductive paste at the timing of being disposed through the openings of the mask.

Abstract: A decoration plate (10, 10A, 10B, 10C, 10D) including a light guide substrate (100), a decorative film (200), and a circuit board assembly (20, 20A) is provided. The light guide substrate (100) has a first surface (100S1) and a second surface (100S2) disposed on opposite sides, and has a first groove (Gl) on the first surface (100S1). The decorative film (200) is disposed on the second surface (100S2) of the light guide substrate (100). The decorative film (200) defines an operating region (DR). The circuit board assembly (20, 20A) is disposed on the first surface (100S1). The circuit board assembly (20, 20A) includes a light-emitting element (300) and a touch sensing layer (400). The light-emitting element (300) is accommodated in the first groove (Gl). A position of the touch sensing layer (400) corresponds to a position of an orthogonal projection of the operating region (DR) on the first surface (100S1).

Abstract: A multiview backlight and a multiview display employ multibeam elements configured to provide a tilted plurality of light beams having different principal angular directions corresponding to different view directions of a plurality of views of the multiview display. Further, the tilted plurality of light beams has a tilt toward a center of a view zone of the multiview display to provide converging views. The multiview backlight includes a light guide and an array of the multibeam elements. The multiview display further includes multiview pixels that include view pixels to modulate the tilted plurality of light beams having the tilt and the different principal angular directions.
