    摘要： A display apparatus includes a timing controller which outputs image data, a data control signal and a first gate control signal, a data driving circuit which receives the image data and converts the image data into data voltages, a control signal converting circuit which delays the first gate control signal by a reference time period to convert the first gate control signal into a second gate control signal based on a reference signal, a gate driving circuit which outputs gate signals based on the second gate control signal, and a display panel which displays an image corresponding to the one line of the data voltages based on the gate signals. Each gate signal rises at a point in time delayed from a starting point of a corresponding horizontal scanning period by the reference time period and falls before an ending point of the corresponding horizontal scanning period.

    摘要： In a backlight device and a driving method thereof, a voltage controller controls a voltage level of a first input voltage in response to a dimming signal to output a second input voltage. A pulse generator receives the second input voltage from the voltage controller and generates a pulse signal having a duty ratio corresponding to the dimming signal and a high voltage level corresponding to the second input voltage. An inverter generates a lamp driving signal based on the pulse signal. At least one lamp included in the backlight device is turned on or turned off in response to a lamp driving signal to adjust luminance of the backlight device.

    摘要： Disclosed is an antenna having an antenna radiator formed by printing electrically conductive ink on a substrate. An antenna radiator according to an embodiment of the present invention is formed to the same thickness as a skin depth with respect to an operation frequency of the antenna. Therefore, an antenna can be fabricated using a small amount of electrically conductive ink while not reducing the gain of the antenna. Further, an antenna radiator according to another embodiment of the present invention is formed to the same thickness as a skin depth with respect to a predetermined frequency at a corresponding hot spot with respect to the frequency. Accordingly, an amount of electrically conductive ink used can be further reduced while maintaining the gain of the antenna.

    摘要： Various embodiments of the invention relate to a low-cost network system that can reduce the network cost by connecting a base station controller (BSC) with a base transceiver station (BTS) by the use of matching units that match an E1/T1 line to an IP line. In one embodiment, the system comprises a BSC matching unit (BSCMU) and a BTS matching unit (BTSMU). The BSCMU, connected to the BSC through a first dedicated line, converts a first dedicated-line data signal, received from the BSC, into a first IP signal to be transmitted through an IP line and converts a received second IP signal into a second dedicated-line data signal to be transmitted to the BSC. The BTSMU, connected to the BTS through a second dedicated line, converts the first IP signal into the first dedicated-line data signal to be transmitted to the BTS and converts the second dedicated-line data signal, received from the BTS, into the second IP signal.
