Abstract

See full text

A data driving circuit, a display module, and a display device are provided. The data driving circuit is configured to drive a display device to display different grayscale images. The voltage-dividing circuit includes 2n voltage-dividing signal terminals arranged sequentially from low to high voltage. The switching circuit includes 2n switching sub-circuits. Each of the 2n switching sub-circuits includes a receiving terminal, a first output terminal, and a second output terminal. The receiving terminal is electrically coupled to the voltage-dividing signal terminal. The voltage selecting circuit includes 2n selecting signal terminals. Each of the 2n selecting signal terminals is electrically coupled with the first output terminal of one of the 2n switching sub-circuits and the second output terminal of one of the 2n switching sub-circuits.
