  • Patent number: 8823616
    Abstract: A liquid crystal display device includes; gate lines disposed on a display region, data lines disposed on the display region, wherein the data lines intersect with, and are insulated from, the gate lines, a gate driver which drives the gate lines, a plurality of data drivers which generate a data voltage from an input power source voltage and supply the data voltage to the data lines, and a power source voltage supplying unit which supplies different power source voltages to each of the data drivers according to a distance of each data driver from the gate driver.

  • Patent number: 8199085
    Abstract: A display apparatus and a driving method thereof, in which the display apparatus includes a temperature sensor detecting a temperature, a first memory, a timing controller that receives an (n?1)th image signal and an nth image signal of consecutive frames, corrects the nth image signal and outputs the nth image signal, wherein the timing controller generates a clock signal whose phase varies according to the detected temperature, writes the nth image signal in the first memory in synchronization with the clock signal, reads the (n?1)th image signal from the first memory, and compares the nth image signal and the (n?1)th image signal with each other to then correct the nth image signal based on the comparison result, a data driver that provides an image-data voltage corresponding to the corrected signal of the nth image signal, and a liquid crystal panel that displays an image corresponding to the image-data voltage.

  • Publication number: 20100110056
    Abstract: The present invention relates to a connector that includes a body and a plurality of terminals. The body extends in a first direction and includes at least one side surface coupled with an external device. The terminals include a conductive material. The terminals are arranged on the body, extend in a second direction perpendicular to the first direction, and are arranged in the first direction to receive a voltage and a control signal from the external device. At least one terminal of the terminals has a length in the second direction greater than a length of remaining terminals in the second direction, the at least one terminal to receive a ground voltage.
