An apparatus for simultaneously adjusting brightness and contrast of a display includes: a key ( 1 ) for receiving a luminance instruction inputted by a user; an SCM (Single Chip Micyoco) ( 2 ) for obtaining a luminance value corresponding to the instruction, and for calculating a brightness value and a contrast value according to the obtained luminance value; an AID (Analog/Digital) converter ( 3 ) for converting the brightness value and the contrast value into respective voltage pulse signals; a signal amplifier ( 4 ) for adjusting the amplitude sizes of the voltage pulse signals, and outputting the voltage pulse signals as LVDS (Low Voltage Differential Signals); a back light controller ( 5 ) for receiving the LVDS, and controlling video output of the adjusted brightness and contrast; a display screen ( 6 ) for displaying luminance values and images according to the adjusted brightness and the contrast; and a power source ( 7 ). A related method is also disclosed.
