Abstract: 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.

Abstract: A memory is provided, which comprises an electrically erasable and programmable read only memory (EEPROM) configured to store an operation system and to be rewritable in response to a write operation signal, an address comparator configured to be connected to Inter Integrated Circuit (I2C) lines and output the write operation signal to the EEPROM in response to an external signal, a digital-to-analog converter (DAC) unit configured to determine whether to connect a DAC resistor and the I2C lines in response to the external signal and a pull-up resistor unit configured to be connected to the I2C lines.
