Abstract: A display apparatus includes a display panel including pixels, a gate driver to sequentially apply a gate signal to gate lines in response to a gate control signal, a first source driver to apply a first data voltage to data lines in response to a data control signal, and a second source driver disposed at an opposite side of the display panel from the first source driver with respect to the display panel. The second source driver is configured to apply a second data voltage to the data lines at every time period, at which the gate signal is applied to the gate lines, in response to the clock signal. The pixels display a gray scale in response to the first and second data voltages, and a time period of a rising edge of the clock signal is the same as a time period of a rising edge of the gate signal. In addition, the high level period of the clock signal is shorter than the high level period of the gate signal.

Abstract: A display apparatus includes a display panel that includes pixels for receiving data voltages in response to gate signals, and dummy pixels, a driver for driving the pixels and the dummy pixels, a kickback voltage detector for detecting a kickback voltage of the dummy pixels, and a timing controller. The timing controller calculates a temperature corresponding to the kickback voltage, compares the calculated temperature with a reference temperature, and controls the driver to compensate a display panel image quality based on a temperature variation that corresponds to a difference between the calculated temperature and the reference temperature.

Abstract: A light source apparatus includes a display panel luminance change storing part, a light source part and a light source driving part. The display panel luminance change data storing part stores a display panel luminance change data indicating a luminance change of a display panel with respect to time. The light source part provides a light to the display panel and outputs a light source luminance. The light source driving part drives the light source part based on the display panel luminance change data so that the light source luminance is decreased when a display panel luminance is increased and the light source luminance is increased when the display panel luminance is decreased. Thus, a display quality of a display apparatus may be enhanced.
