Abstract: A display apparatus includes a plurality of display panels, a power voltage generator and a driving controller. The power voltage generator generates power voltages of the plurality of display panels. The driving controller receives the power voltages from feedback points of the plurality of display panels and generates a control signal and controls levels of the power voltages based on fed-back power voltages from the feedback points of the plurality of display panels. The power voltage generator adjusts the levels of the power voltages and generates compensation power voltages based on the control signal.

Abstract: A timing controller includes: a temperature sensor to sense an ambient-3.6 temperature; a memory to store a liquid crystal response time corresponding to the temperature, and a gamma signal corresponding to the ambient temperature; a field number determinator to identify the liquid crystal response time corresponding to the ambient temperature from the memory, and to determine a number of fields corresponding to the liquid crystal response time; and a gamma converter to identify the gamma signal corresponding to the ambient temperature and the number of fields from the memory, and to convert an image signal into an image data signal corresponding to the gamma signal.
