Abstract
Embodiments of the present application provide a digital-to-analog conversion circuit, a method thereof and a display apparatus. The digital-to-analog conversion circuit comprises a voltage dividing sub-circuit, having 2of voltage dividing signal terminals and 2−1 of sub-voltage dividing signal terminals; a first voltage selecting sub-circuit, configured to receive the first bit to the (n−m)bit of the digital signal, and convert it into a first analog signal; a second voltage selecting sub-circuit, configured to receive the (n-m+1)bit to the nbit of the digital signal and to convert it into a second analog signal; and a buffering sub-circuit, configured to generate an analog signal based on the first analog signal, the second analog signal and the signal from the ivoltage dividing signal terminal and to output the analog signal to an analog signal outputting terminal of the digital-to-analog conversion circuit.
