A display system comprises an adjustment unit, a pulse generating unit and a light tube. The adjustment unit comprises a thermal resistor and generates an adjustment signal according to the temperature. The pulse generating unit generates a pulse driving signal according to the adjusting signal. When the temperature falls, the duty cycle of the pulse driving signal is increased. When the temperature rises, the duty cycle of the pulse driving signal is decreased. The light tube emits light according to the duty cycle of the pulse driving signal.
