Abstract:
A white light emitting device including: a blue light emitting diode chip having a dominant wavelength of 443 to 455 nm; a red phosphor disposed around the blue light emitting diode chip, the red phosphor excited by the blue light emitting diode chip to emit red light; and a green phosphor disposed around the blue light emitting diode chip, the green phosphor excited by the blue light emitting diode chip to emit green light, wherein the red light emitted from the red phosphor has a color coordinate falling within a space defined by four coordinate points (0.5448, 0.4544), (0.7079, 0.2920), (0.6427, 0.2905) and (0.4794, 0.4633) based on the CIE 1931 chromaticity diagram, and the green light emitted from the green phosphor has a color coordinate falling within a space defined by four coordinate points (0.1270, 0.8037), (0.4117, 0.5861), (0.4197, 0.5316) and (0.2555, 0.5030) based on the CIE 1931 color chromaticity diagram.
Abstract:
An extreme ultraviolet (EUV) mask blank is provided. The EUV mask blank includes a substrate having a first surface and a second surface opposed to each other, a reflective layer having first reflective layers and second reflective layers alternately stacked on the first surface of the substrate, a capping layer on the reflective layer, and a hydrogen absorber layer between the reflective layer and the capping layer, the hydrogen absorber layer configured to store hydrogen and being in contact with the capping layer.
Abstract:
Disclosed herein are a display apparatus, control system for the display apparatus, and a method for controlling the display apparatus. The display apparatus includes a receiver configured to receive content, a display configured to display the received content, a communicator configured to communicate with a user device and an external server. The display apparatus includes a processor configured to acquire information from the user device through the communicator, to request the external server to send additional information related to the received content based on the received content and the information, and to display, when receiving the additional information related to the received content from the external server, the received additional information with the received content.
Abstract:
An aluminum-resin composite with an improved structure for increasing a bonding force between aluminum and resin, and a method of producing the aluminum-resin composite are provided. The aluminum-resin composite may include aluminum etched by a chemical etching solution to form an uneven surface having surface roughness of a mean projection-depression interval RSm from 50 μm to 150 μm and a maximum height Rz from 2 μm to 35 μm, and resin penetrating the uneven surface to be bonded with the aluminum.
