Abstract:
A display panel (400) comprises a display layer (410) including a plurality of pixel arrays (426) offset from each other by spacing regions (435) and a screen layer (415) disposed over the display layer (410) with each of the pixel arrays (426) aligned to project an image portion onto a corresponding portion of the screen layer (415). The screen layer (415) includes a transparent substrate (450), a Fresnel lens layer (455), a diffusing layer (460) and an array of upper spacer supports (440), made of metal, to support the transparent substrate (450) a first fixed distance from the display layer (410). Each of the upper spacer supports (440) is positioned on one of the spacing regions (435). An array of lower space supports (422), aligned with the upper spacer supports (440), is arranged to support the display layer (410) and forms air cavities defining optical pathways (424) which guide light from light sources (421) to the screen layer (415).
Abstract:
A display device including a backlight unit; and an image forming unit configured to transmit or block light emitted from the backlight unit to create an image, wherein the backlight unit includes a light source, a reflector sheet configured to absorb light having a predetermined wavelength range among light emitted from the light source, and to reflect non-absorbed light, and an optical sheet configured to absorb light having the predetermined wavelength range among the light emitted from the light source, and to transmit non-absorbed light.
Abstract:
Un dispositif de rétroéclairage (20) comprend : - au moins une rangée d'une pluralité de sources de lumière (22); - un réflecteur (30) disposé de manière à réfléchir en partie au moins la lumière émise par les sources de lumière (22); et - un diffuseur (25) disposé de manière à recevoir au moins la lumière réfléchie par le réflecteur (30). Le réflecteur (30) comprend au moins une paroi (38) s'étendant le long des sources de lumière (22) et ayant une forme présentant au moins deux orientations différentes. Une unité de génération d'image, un afficheur tête haute et un véhicule associés sont également proposés.
Abstract:
A method of transferring semiconductor devices to a product substrate includes positioning a surface of the product substrate to face a first surface of a semiconductor wafer having the semiconductor devices thereon, and actuating a transfer mechanism to cause the transfer mechanism to engage a second surface of the semiconductor wafer. The second surface of the semiconductor wafer is opposite the first surface of the semiconductor wafer. Actuating the transfer mechanism includes causing a pin to thrust against a position on the second surface of the semiconductor wafer corresponding to a position of a particular semiconductor device located on the first surface of the semiconductor wafer, and retracting the pin to a rest position. The method further includes detaching the particular semiconductor device from the second surface of the semiconductor wafer, and attaching a particular semiconductor device to the product substrate.
