Abstract: A method and system for adjusting the luminance of a cold cathode fluorescent lamp (CCFL) is provided, which operates in a BIOS of a liquid crystal screen in a computer-executable way. A plurality of sets of time-luminance values of the CCFL is stored in the BIOS. First, the image quality of the liquid crystal screen is detected with a current image, and if the image quality is poor, a current time value and a current actual luminance value of the liquid crystal screen are then detected, and a plurality of sets of time-luminance values of the CCFL are searched, according to which the voltage of the CCFL is adjusted such that the current actual luminance value is adjusted accordingly. Therefore, by implementation of the method and system, the phenomenon of luminance reduction over time when using a liquid crystal screen with a CCFL is avoided.
