A digital to analog converter for an analog Liquid Crystal Display (LCD) includes a digital inlet, a latching circuitry, a voltage level shifter circuitry, a switching circuitry, and a resistance network with a resistance compensatory circuitry. The resistance network with the resistance compensatory circuitry is electrically connecting with the switching circuitry and adapted to regulate a pattern of the analog output signal so as to optimize the analog output signal. Specifically, the resistance network with a resistance compensatory circuitry is to produce the best linear conversion from the digital signal to the analog signal for use by the LCD.
