摘要： A display device includes a display panel having pixels. A timing controller generates a first control signal and data control signals. Data driving circuits each recover a data signal from a corresponding data control signal of the data control signals in response to the first control signal, generate a data voltage corresponding to the data signal, and provide the data voltage to the display panel. Each of the data driving circuits includes: a setting unit configured to acquire a setting value from the data control signal; an equalizer configured to compensate for distortion of the corresponding data control signal according to the setting value to output compensated data control signal; and a recoverer configured to recover a clock signal from the compensated data control signal and recover the data signal from the compensated data control signal based on the clock signal.

摘要： A display device and method is provided that permits selection of a first lookup table or a second lookup table to operate the data driver at respectively different temperatures to prevent heat from damaging the display device. The display device includes a detector which detects the number of toggles in which the amount of change in gray values of successive pixels driven by the same data line in one frame is equal to or greater than a reference gray change amount. A comparator compares the number of toggles detected by the detector with a reference number of toggles, and a lookup table selector which selects any one of a first lookup table and a second lookup table based on the comparison result of the comparator and provides the selected first lookup table or second lookup table to a data driver.
