PROBLEM TO BE SOLVED: To provide a system for displaying an image, and a digital-to-analog converting method. SOLUTION: A digital-to-analog converter comprises a charge sharing circuit, a discharging circuit and a voltage boosting circuit. The charge sharing circuit sequentially receives first to (N-1)th bits of serial digital signals. The charge sharing circuit shares and stores charges between a first capacitor and a second capacitor according to a charging voltage, a ground voltage, a first clock signal and serial data signals. The discharging circuit discharges the charge sharing circuit following a reset signal. After the voltage boosting circuit receives the (N-1)th digital signal, the charge boosting circuit determines whether to boost a first terminal or a second terminal of the second capacitor in voltage or not based on an Nth digital signal. After the voltage boosting circuit receives the Nth serial digital signal, the charge sharing circuit outputs an analog signal from the second terminal of the second capacitor.
