Abstract:
The invention relates to a grid array type lead frame having a plurality of leads classified into groups by length. The leads extend to respective lead ends, in each of which at least one different plane direction-converting lead part and/or at least one identical plane direction-converting lead part is formed by at least one bending part, whereby the lead ends are distributed in a grid array. The invention also includes a grid array type lead frame, which is as small as or similar to that of semiconductor chip in area while the lead ends are arrayed on one plane, and are at a farther distance away from neighboring ones but in a higher number per area, in such a manner that they form a grid array.
Abstract:
A semiconductor package provided with a heat sink adapted to discharge heat from the package. The package has an oxidation film formed on an upper surface portion of the heat sink to which a semiconductor chip is attached, thereby improving the bonding between the semiconductor chip and heat sink to prevent the occurrence of an interface peel-off and the formation of cracks. This results in an improvement in reliability. A silver layer or a double layer consisting of a nickel layer and a palladium layer formed over the nickel layer is plated on the remaining upper surface portion of the heat sink not attached with the semiconductor chip. Accordingly, it is also possible to achieve easy ground bonding and power bonding. This results in an improvement in performance of the finally produced semiconductor package.
Abstract:
Provided is a liquid composition for treating stomatitis, the liquid composition including: an epidermal growth factor; an adhesive polymer; and at least one stabilizer selected from the group consisting of ethylenediaminetetraacetic acid (EDTA) and salts thereof, histidine, lysine and inorganic acid salts thereof, arginin and inorganic acid salts thereof, and dextran. The liquid composition includes a stabilizer selected from EDTA (or salts thereof) and a certain amino acid (or inorganic acid salts thereof) and thus, physicochemical and biological stability of the epidermal growth factor can be substantially increased. Thus, the liquid composition can be stored and distributed for a long period of time. The stabilized composition includes an adhesive polymer, and thus, when ejected in a spray form in the mouth of a user, the liquid composition can be quickly attached to an inflammation site and exhibits effectiveness for a long period of time.
Abstract:
The present invention relates to a graphene-nanoparticle composite having a structure in which nanoparticles are crystallized at a high density in a carbon-based material, for example, graphene, and, more particularly, to a graphene-nanoparticle composite capable of remarkably improving physical properties such as contact characteristics between basal planes of graphene and conductivity since nanoparticles are included as a large amount of 20 to 50% by weight, based on 100% by weight of graphene, and a method of preparing the same.
Abstract:
The present invention relates to a nanoliposome comprising a liposome membrane containing esterified lecithin, and one or more physiologically active ingredients included in inner space of the liposome membrane; a method for preparing the same; and a composition for preventing or treating skin diseases, comprising the same. The nanoliposome according to the present invention has long-term stability and uniformity, and so can be used to prepare a composition for skin having excellent moisturizing and penetrating properties, such as cosmetics, medicament for treating skin diseases, or the like. In particular, the present composition for preventing or treating skin diseases comprises epidermal growth factor included in the nanoliposome, thereby showing an excellent effect of stimulating skin-penetration and good pharmaceutical stability. Also, the esterified lecithin used in preparing liposome can provide effects of softening skin and stimulating skin-penetration, thereby enhancing the penetration of epidermal growth factor and natural extract into skin, as well as additional moisturizing effect which is advantageous in treating skin diseases. Further, since the present composition comprises nanoliposome prepared by containing esterified lecithin in liposome membrane, the conventional problems of heating and dispersing active ingredients at high temperature (70° C. or more), low stability and uniformity, or the like can be solved.
Abstract:
A backlight assembly including direct-type lamps and an edge-type lamp and a liquid crystal display having the backlight assembly. The direct-type lamps are arranged with a predetermined interval to emit light, and the edge-type lamp is provided at a side portion of a light guide plate provided above or below the direct-type lamps. The light guide plate and a light guide pattern output light, which is emitted from the edge-type lamp, through a space between two adjacent direct-type lamps. The backlight assembly supplies light to the light receiving region such that brightness is uniformly distributed throughout the light receiving region regardless of the position of the direct-type lamps.
Abstract:
A method for managing a broadcast message group includes storing a broadcast message and multiple messages associated with the broadcast message, classifying the multiple messages into multiple message subgroups, generating the broadcast message group including the broadcast message and the multiple message subgroups, and displaying the broadcast message and the multiple message subgroups if the broadcast message group is selected. An apparatus includes a storage unit to store a broadcast message and a reply message associated with the broadcast message, a display unit to display a broadcast message group in a message list, a controller to generate the broadcast message group including the broadcast message and the reply message. The display unit displays the broadcast message and the reply message if the broadcast message is selected.
Abstract:
A backlight assembly includes; a plurality of light guide blocks disposed substantially in parallel with each other along a first direction, each of the plurality of light guide blocks including; a light guide plate (“LGP”) having a wedge-shape decreasing in thickness from a first side thereof to a second side thereof, and a light source unit disposed facing a side surface of the LGP, and a light source driving unit which individually controls the light source units of the plurality of light guide blocks to emit light via a local dimming method.
Abstract:
A backlight unit includes a light guide plate configured to guide light and including at least one light incident surface for receiving light, and a light exit surface for directing the received light toward a display panel, a plurality of light sources configured to emit light toward the light incident surface, and an optical member disposed at a light exit surface of the light guide plate to direct light output from the light guide plate. The optical member may include at least one sheet, which may have a first portion positioned over the light exit surface of the light guide plate, and a second portion positioned over the light incident surface.
Abstract:
