摘要:
A novel black matrix, a method for preparing the same, and a flat display device and an electromagnetic interference filter to which the black matrix is applied. The black matrix is prepared by exposing a photoactive compound to form a latent pattern of nuclei for crystal growth and treating the latent pattern of nuclei for crystal growth with a metal salt solution to give a metal particle-deposited pattern; forming an electroless Ni-plated layer on the metal particle-deposited pattern; and forming an electroless Cu-plated layer on the electroless Ni-plated layer. Exhibiting improved black tone, which is achieved only by a selective multilayer plating process, without using expensive vacuum sputtering apparatus or a photolithographic process, the black matrix can be applied to various flat display devices. In addition, due to improved electric conductivity, the black matrix can be used in an electromagnetic interference filter, without employing an additional front surface blackening process.

A liquid crystal display device is provided. The liquid crystal display device includes: a liquid crystal display panel having an upper substrate and a lower substrate, a backlight assembly; a top cover surrounding the liquid crystal display panel, and a pad located on an upper surface of the lower substrate. The pad distributes a force applied by the top cover to the lower substrate, thereby reducing light leakage of the backlight assembly.

A clothing dryer including a first exhaust duct mounted inside the clothing dryer and adapted to exhaust air from the clothing dryer and a second exhaust duct to be inserted on the first exhaust duct. A pressing portion is mounted on the first exhaust duct to press both the first and second exhaust ducts, and a fixing portion is affixed to a rear surface cover of the clothing dryer so as to fixedly maintain the first exhaust duct relative to the rear surface cover. A positioning portion is provided to couple the pressing portion to the first exhaust duct and to prevent additional insertion of the second exhaust duct beyond a predetermined length. Thereby, the first and second exhaust ducts are able to be easily connected to each other while preventing optional adjustment of a connection length therebetween, and the first exhaust duct is stably kept so as not to rotate when it is assembled in the clothing dryer. Further, the first and second exhaust ducts are self-sealed to each other.

A VCSEL includes a substrate having a partially removed portion; a metal-assisted DBR having a metal layer and a first mirror stack, wherein the metal layer is located at the partially removed portion of the substrate; an active region having a plurality of quantum wells over the metal-assisted DBR; and a second mirror stack over the active region, wherein a number of alternating layers of the first mirror stack is substantially smaller than a number typically required for a VCSEL without the integrated metal reflector. Such a metal-assisted DBR is especially useful for a long-wavelength VCSEL on a InP substrate or a red-color VCSEL on a GaAs substrate.

A vertical cavity surface emitting laser (VCSEL) structure includes a bottom distributed Bragg reflector (DBR) arranged over a substrate; a metal layer interposed between the bottom DBR and the substrate, wherein the metal layer and bottom DBR form a composite mirror structure. A patterned dielectric layer may be interposed between the metal layer and the bottom DBR to reduce a deleterious chemical reaction between the metal layer and the bottom DBR. The metal layer directly contacts a portion of the bottom DBR to enhance the electrical and thermal conductivity of the

The present invention relates to an anti-reflection film for preventing the reduction of image quality caused by light reflection in various display screens, such as CRT, liquid crystal displays (LCD) and plasma display panels (PDP). The anti-reflection film 100 comprises a substrate consisting of a transparent polymer film 110, and at least one conductive polymer layer 120 formed by depositing a heterocyclic conjugated polymer on at least one surface of the substrate. Thus, the inventive anti-reflection film has high transparency and small thickness, and anti-static and/or electromagnetic shielding properties, such that it can be widely used in electrical, mechanical and electronic fields.

A drum-type washing machine employs a plurality of lifts each having a curved portion and a concave recess, to improve washing performance, decrease washing time, and reduce a vibration and noise occurring during high-speed operation. The drum-type washing machine includes a drum for receiving laundry, the drum having an inner circumferential surface and being rotatable about a central axis; a rotational shaft coupled to the drum for transferring a rotational force to the drum; and a plurality of lifts mounted to the drum and installed at intervals around the inner circumferential surface, each lift having a predetermined length with respect to the central axis of the drum and having an overall curved configuration formed by a curved portion disposed toward the rotational shaft, the overall curved configuration consisting of an inner side and an outer side. The concave recess may be formed on one or both sides of the lift.
