A data line driving circuit for a display device having a plurality of data lines is provided to include a plurality of data line drivers respectively coupled to the data lines. Each data line driver includes a register unit to store video data having a pixel value, a pulse width modulation unit generating a PWM signal having a pulse width positively correlated with the pixel value, and a charge-discharge unit performing charge-discharge operation to generate a data voltage on a respective one of the data lines according to the PWM signal. A magnitude of voltage variation on the respective data line is positively correlated with the pulse width of the PWM signal during the charge-discharge operation.
