The ad-hoc wireless communication method using a sector antenna according to an exemplary embodiment of the present invention, includes: transmitting a requesting message for setting a communication link while changing transmission power to each sector of the sector antenna; receiving a response message corresponding to the requesting message from a receiving node of each sector; configuring a routing table for the transmission power for each sector based on the received response message; and transmitting data at the transmission power for each sector by referring to the routing table.
Abstract:
A polarizing plate includes a base layer, a buffer layer and a plurality of conductive lattice lines. The buffer is formed on the base layer. The conductive lattice lines are formed on the buffer layer in a stripe shape to reflect and polarize incident light. The buffer layer protects the conductive lattice lines. The conductive lattice lines include a silver (Ag) layer or an aluminum (Al) layer. Therefore, the buffer layer protects the conductive lattice lines, so that the lifetime of the polarizing plate may be increased. Furthermore, the display quality of a display panel and a display device having the polarizing plate may be enhanced.

Abstract:
A light condenser for an LCD includes a base layer, a condensing layer and a lower surface-treated layer. The condensing layer is disposed on the base layer and has a condensing pattern formed therein. The lower surface-treated layer is disposed below the base layer and has a plurality of protrusions extending downwardly therefrom. Each of the protrusions has a substantially round shape. The novel light condenser enables the number of optical elements needed in a display apparatus to be reduced, thereby reducing LCD manufacturing costs. Additionally, the light condenser prevents a mutual scratching and adhesion problem between the condenser and a diffusing plate of the LCD, thereby improving the quality of the image produced by the display.

The side pin cushion circuit comprises a vertical deflection portion for generating a saw-tooth signal whose period varies according to the frequency of a vertical synchronizing signal, first amplifying portion for amplifying the saw-tooth signal supplied from the vertical deflection portion and converting the amplified saw-tooth signal to a pin cushion signal, a second amplifying portion for amplifying the pin cushion signal supplied from the first amplifying portion and supplying the amplified pin cushion signal to a mixer, a controlling switch for switching the pin cushion signal supplied to the mixer from the second amplifying portion, and a switch controller for detecting the frequency of the vertical sychronizing signal depending on the voltage level of the saw-tooth signal supplied from the vertical deflection portion and for controlling the controlling switch every period corresponding to the frequency of the detected vertical synchronizing signal.
Abstract:
A light source assembly includes first light sources emitting first light in a first wavelength range, second light sources emitting second light in a second wavelength range which is at least partially different from the first wavelength range, and an optical member on which light emitted from the first light sources and the second light sources is incident. A distance between adjacent first light sources, and a distance between adjacent second light sources is defined as an average pitch. The average pitch of the second light sources arranged in a specific direction, is larger than the average pitch of the first light sources arranged in the specific direction. The optical member has a reflectance with respect to the second light, which is larger than a reflectance with respect to the first light.
