This invention applies a luminance detection device to determine the brightness of the place where the display device is located and adjusts the power of the light source accordingly. The photo sensor can also be place in front of the light source to detect the color deviation and to compensate the deviation by adding or subtracting the value of the corresponding color component which has color deviation. The image to be displayed is examined to determine the level of luminance and adjusts the power of the light source accordingly.
