Abstract:
A photosensitive composition and a method of manufacturing a substrate used for a display device are disclosed. The photosensitive composition includes an acrylic based copolymer, a photo-initiator, a photo-sensitizer and a solvent. Thus, a photosensitivity of the photosensitive composition for ultra violet light of a long wavelength may be improved.
Abstract:
A method is provided to transmit a signal by a transmitter in a communication system. The method includes predicting a receiver noise signal received from a receiver, and increasing an intelligibility of a transmitter signal using the receiver noise signal. The transmitter signal includes a transmitter noise signal and a transmitter speech signal. The transmitter cancels the transmitter noise signal from the transmitter signal and intensifies the transmitter speech signal in consideration of the receiver noise signal.
Abstract:
A wireless interface probe card includes a substrate member and a transmission member. The substrate member has a plurality of probe terminals arranged at a constant pitch. The probe terminals may directly contact a plurality of pads arranged at a constant pitch on each of a plurality of semiconductor chips arranged on a wafer to perform a test of the semiconductor chips arranged on the wafer. The transmission member is arranged on the substrate member, wirelessly receives a test signal and provides the received test signal to the pads of the wafer through the probe terminals, and wirelessly and externally transmits an electrical characteristic signal provided from the pads of the wafer through the probe terminals.
Abstract:
An optical lens includes a recessed part and a refracting part. The recessed part has a substantially circular plan view and a substantially V shaped cross-section. The recessed part forms an angle of no more than an angle of about 20° with respect to a vertical line. The recessed part has a plurality of curved surfaces including different radii so that a light incident into the recessed part is totally reflected from the curved surfaces. The refracting part has a substantially circular plan view extended from the recessed part. A light incident into the refracting part and the reflected light from the recessed part are refracted from the refracting part. Therefore, a luminance uniformity and a color uniformity are improved.
Abstract:
Disclosed herein are a light guide plate and a backlight assembly using the same, which may improve the uniformity of light using prism patterns having a trapezoidal shape. The light guide plate includes a body, a plurality of first projections, and a plurality of second projections. The body includes an incident surface to which light is incident and an emitting surface from which the incident light is emitted. The plurality of first projections is disposed on the emitting surface of the body and has a trapezoidal shape in a section perpendicular to the incident surface. The plurality of second projections is disposed on the emitting surface of the body and has a shape symmetrical to a shape of the first projections.
Abstract:
