    Abstract: A gate driver includes a first shift-register including a plurality of odd-numbered stages which outputs a plurality of odd-numbered original gate signals having a pre-charge pulse and a main-charge pulse in synchronization with a first gate clock signal, a second shift-register comprising a plurality of even-numbered stages which outputs a plurality of even-numbered original gate signals having a pre-charge pulse and a main-charge pulse in synchronization with a second gate clock signal, a first inverter configured to output a first inversion pre-charge control signal having a phase opposite to a phase of a first pre-charge control signal, and a second inverter configured to output a second inversion pre-charge control signal having a phase opposite to a phase of a second pre-charge control signal.

    Abstract: An I2C router system includes an I2C router part, a first slave device and a second slave device. The I2C router part includes a first I2C router configured to output a first I2C signal via a first I2C bus, and a second I2C router configured to output a second I2C signal via a second I2C bus. The first slave device can be configured to receive the first I2C signal via the first I2C bus. The second slave device can be configured to receive the second I2C signal via the second I2C bus.

    Abstract: A display apparatus including a classifier configured to classify image data into preset data of an n-bits (“n” is a natural number), a toggle counter configured to count a number of toggles based on preset data of a present horizontal line and a previous horizontal line and to calculate a final toggle number using a weighted values corresponding to a swing width between data voltages of the present and previous horizontal lines, a determiner configured to determine a representative toggle number of a present frame based on a plurality of final toggle numbers of the present frame, compare the representative toggle number with a plurality of threshold values and determine a level of a power control signal based on a compared result.

    Abstract: A timing controller includes a data grouping part that generates a plurality of grayscale groups based on input image data, each grayscale group including n×m grayscales, a grayscale classifying part that generates a plurality of grayscale patterns respectively corresponding to the grayscale groups, a grayscale in the grayscale groups being classified in the grayscale patterns as a first grayscale if the grayscale is higher than a first reference grayscale or as a second grayscale if the grayscale is lower than a second reference grayscale, a pattern comparing part that compares each grayscale pattern with a first pattern including the n×m first and second grayscales, a pattern counter that counts a number of patterns of the grayscale patterns that are substantially the same as the first pattern, and a driving mode changing part that changes a driving mode of a display panel when the number is greater than a reference number.
