1. A liquid crystal display (LCD) comprising:
a memory for storing a relationship between a backlight magnitude and an accumulated working time, a relationship between a transmittance and a high reference voltage, and the transmittance, the backlight magnitude, and a multiplying product of the transmittance and the backlight magnitude when the LCD display is manufactured;
a timing controller for reading data stored inside the memory;
a pulse-width modulation chip for generating the high reference voltage according to the accumulated working time and the data transferred from the timing controller;
a gamma generating unit for generating gamma voltages according to the high reference voltage; and
a driving chip for receiving the gamma voltages to drive the LCD display;
wherein a multiplying product of the backlight magnitude corresponding to the accumulated working time and the transmittance corresponding to the high reference voltage is equal or proximate to the multiplying product of the transmittance and the backlight magnitude when the LCD display is manufactured.
