Abstract: A data transmitting system includes a transmitter configured to transmit first unit data having a first bit length and second unit data sequentially with the first unit data and having the first bit length and a receiver configured to receive the first unit data and the second unit data. The transmitter is configured to transmit the second unit data to the receiver when a last bit of the first unit data and a first bit of the second unit data have different values and to invert the first bit of the second unit data and transmit the second unit data having the inverted first bit to the receiver when the last bit of the first unit data and the first bit of the second unit data have the same value.

Abstract: A display device includes a display panel including a plurality of pixels, a voltage generator which generates a gate on voltage having a first voltage level that satisfies a target charging ratio of a pixel of the plurality of pixels, a voltage controller which receives an image signal and generates a voltage control signal when the image signal includes a predetermined reference pattern, a gate driver which generates a gate signal provided to the plurality of pixels based on the gate on voltage, a data driver which generates a data signal provided to the of the plurality of pixels based on the image signal, and a timing controller which generates control signals that control the gate driver and the data driver. The voltage generator changes the gate on voltage to have a second voltage level lower than the first voltage level based on the voltage control signal.

Abstract: A method of obtaining overdriving data includes providing a first data voltage corresponding to a current line reference gray level to a second pixel for first and second data writing times for first and second pixels in a first frame, measuring first luminance based on the first data voltage, applying a second data voltage corresponding to a previous line reference gray level for the first data writing time in a second frame, providing a third data voltage of an overdriving voltage corresponding to a predicted overdriving gray level added to the first data voltage for the second data writing time in the second frame, measuring second luminance based on the third data voltage, and determining an overdriving value corresponding to a reference gray level pair of the current and the previous line reference gray level as the predicted overdriving gray level when the first and second luminance are the same.
