A digital to analog converter, a method for driving the same, and a display device are provided. The digital to analog converter includes: a first resistor string, 2m first multiplexers, a first voltage selector, a second resistor string, a second voltage selector, and a second multiplexer, where the 2m first multiplexers, the first voltage selector, and the second voltage selector operate in cooperation with each other so that the entire second resistor string can be connected in series to the first resistor string for further division.
