    摘要： A white balance calibration method includes providing red light, green light, blue light, and white light to a display panel according to first image data; detecting a first temperature of a backlight module when the backlight module provides the red light, green light, blue light, and white light to the display panel; detecting whether luminance of white light of each pixel is lower than maximum luminance of a white light emitting diode (LED) corresponding to the pixel when a first difference between the first temperature and a standard temperature stored in a lookup table is less than a predetermined value; controlling the backlight module to turn on a red LED, a green LED, and a blue LED corresponding to the pixel during turning-on of the white light if the luminance of the white light is lower than the maximum luminance of the white LED corresponding to the pixel.
