Abstract:
The present invention provides a flat panel display device, which includes a backlight system and a display panel. The backlight system includes a light source, a light homogenization mechanism, and a back frame. The back frame carries the light source and the light homogenization mechanism, and the light homogenization mechanism guides light from the light source into the display panel. The back frame includes primary assembling pieces, secondary assembling pieces, and an adjustable bracing piece. According to practical needs of the back frame, different materials are used for primary assembling pieces at different locations. The available mounting points between the bracing piece and the primary assembling pieces or the secondary assembling pieces are of a number of at least two so that the bracing piece is selectively mounted to the back frame at different positions. The present invention also provides a stereoscopic display device and a plasma display device. The flat panel display device, the stereoscopic display device, and the plasma display device of the present invention have a simple back frame structure, reduce the expenditure of the back frame mold, and also save the material used for back frame so as to lower down the cost of flat panel display device and meet different requirements for mounting.

Abstract:
The present invention discloses a back plate of a liquid crystal display (LCD) module and a splice structure thereof. The back plate is assembled at least by a first back plate portion and a second back plate portion, wherein at least one splice structure is defined between the first back plate portion and the second back plate portion, and the shapes of two sides of the splice structure are correspondingly engaged with each other. Besides, the convex portion is provided with a fixing hole thereon, and the concave step portion is correspondingly provided with a fixing pillar therein. The fixing pillar passes through the fixing hole to fix the first back plate portion and the second back plate portion. The present invention can use different type of material to assemble into the back plate, so as to intensify the splicing strength except for decreasing the material cost.

Abstract:
A server, upon receiving a request to complete a call over a packet-switched network, looks up an address on the packet-switched network on a local table. If the local table does not contain a matching address, the server asks a routing server to identify a receiving server address. The routing server identifies a suitable address and sends a message to the originating server containing the address. The receiving server then receives, via the packet-switched network, a message requesting a telephone connection to a second telephone device. Before completing the connection to the second telephone device, information in the message representing the address of the device on the packet-switched network that originated the message is identified and the address information is compared to selected predetermined addresses for permitted origins of the message.
Abstract:
A semiconductor device for ESD protection includes a semiconductor substrate of a first conductivity type and a well region of a second conductivity type formed within the substrate. The well region is characterized by a first depth. The device includes an MOS transistor, a first bipolar transistor, and a second bipolar transistor. The MOS transistor includes a first lightly doped drain (LDD) region of a second depth within the well region, and a drain region and an emitter region within in the first LDD region. The emitter region is characterized by a second conductivity type. The first bipolar transistor is associated with the emitter region, the first LDD region, and the well region, and is characterized by a first trigger voltage. The second bipolar transistor is associated with the first LDD region, the well region, and the substrate, and is characterized by a second trigger voltage.
Abstract:
The invention provides liquid crystalline blends, a device such as a photovoltaic cell using the blend and method thereof. A liquid crystalline blend comprises at least an electron donor and at least an electron acceptor with a weight or molar ratio in the range of from about 1:20 to about 20:1. Another liquid crystalline blend comprises at least an electron donor and at least an electron acceptor, wherein the electron donor, the electron acceptor, or both is (are) halo-substituted such as F-substituted. The donor or the electron acceptor can be excited by an electromagnetic radiation such as solar light to induce electron transfer between the donor and the acceptor. The photovoltaic cell is improved in that favorable molecular arrangement in the blend gives more interfaces between the donor and the acceptor and thus a viable path for dissociation and electrons and/or holes; as well as larger light-harvesting area toward the coming light.
