ABSTRACT:
A LSD (Liquid Crystal Display) apparatus includes an optical sensor for detecting an amount of light of the liquid crystal panel and a voltage setting unit for setting the voltage inputted to the pixels in relation to the amount of light detected by the optical sensor. Furthermore, the voltage setting unit includes a reference data storage unit for storing reference data for each color, a comparison unit for comparing the amount of light detected by the optical sensor with the reference data stored at the reference data storage unit, and a set voltage output unit for setting the voltage to be inputted to the pixels by calculating data compensating a difference between the values compared by the comparison unit. The amount of light of the liquid panel is detected to automatically adjust the voltage to be inputted to the liquid crystal panel in accordance with the amount of the light.
