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.

Abstract: A display device includes a display panel including pixels, and a timing controller which determines a first dimming period and a second dimming period based on a maximum luminance, determines an emission off ratio of the pixels as a first off ratio increasing discretely as the maximum luminance decreases in the first dimming period, and determines the emission off ratio as a second off ratio in the second dimming period.

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.
