  • Patent number: 8330698
    Abstract: A signal generating circuit for a liquid crystal display (LCD) includes circuitry adapted to receive a gate clock signal and an output enable signal. The gate clock signal is a combination of a gate-on signal and a gate-off signal and the output enable signal is operable to adjust the width of the gate-on signal. The signal generating circuit adjusts the output enable signal such that a falling edge of the output enable signal overlaps a rising edge of the gate clock signal and thereby delays the gate clock signal for a selected amount of time.

  • Patent number: 7974103
    Abstract: A signal transfer member for a liquid crystal display (LCD) apparatus includes a power line for receiving power from an external source and for driving a semiconductor chip disposed on the transfer member or the display apparatus. The power line is bent so as to incorporate a serpentine structure, which enables the length of the power line to be easily adjusted and results in the line being longer than a power line formed with a relatively straight structure. Accordingly, the length of the power line can be adjusted to take into account the respective impedances of the chip and the external source so as to suppress electromagnetic waves in the power line. This prevents the creation of noise, distortion of signals, damage to the semiconductor chip, and disconnection of the input interconnection thereof that are caused by the electromagnetic waves, so that product yields are thereby improved.

  • Patent number: 7684393
    Abstract: Provided is a method for transmitting a burst in an optical burst switching system, in which when a burst is generated at an originating node, a burst control packet is transmitted to a destination node by way of a plurality of nodes and then a data burst is transmitted after a pre-allocated offset time. The method includes the steps of obtaining an arrival time of data bursts that survive competition to occupy an output channel among data bursts transmitted to the next node by way of the current node using offset time information in burst control packets for the survived data bursts, checking whether an empty void is present between the survived data bursts by using the obtained arrival time of the survived data bursts, and generating a new data burst originating from the current node, inserting the newly generated data burst into the checked empty void, and transmitting to the next node. This method can improve channel utilization and maximize performance of the optical burst switching system.

  • Patent number: 7539128
    Abstract: Disclosed herein is a method for protecting and restoring a link in an OBS network. The method includes a step of transmitting/receiving a liveness-confirming message for confirming liveness of the link between an up-node and a down-node respectively connected to both ends of the link at a predetermined message transmission period, to judge whether a fault is generated on the link, a step in which the up-node and down-node respectively update link information when it is judged that the link fault is not generated, and a step of restoring the link having the fault using predetermined restoration channel information based on an offered load measured when the link is in a normal state when it is judged that the link fault is generated. Accordingly, a link having a problem can be effectively protected and restored in the OBS network.

  • Publication number: 20080084378
    Abstract: A display device and a method for driving the same wherein the timing of the gate clock signal, which is an output of a timing controller, is changed to a time before a data latch signal is applied, so that degradation of the image due to gate noise can be prevented. That is, a gate turn-on voltage is applied before the data latch signal to turn on thin film transistors in an interval in which a gate turn-off voltage is stabilized. Accordingly, the generation of horizontal streaks in the lower portion of the display device is prevented.
