Display systems include display drivers that receive digital video data and retain digital pixel values corresponding to a row of pixels of a display panel. The retained digital pixel values are digitally compared with a digital count produced by a digital counter and at a transition time determined by the comparison of the digital pixel value and the digital count, a data ramp signal is applied to the pixel. The data ramp signal is configured to be time varying so that the transition time at which the data ramp signal is applied to the pixel can be used to establish a pixel voltage corresponding to a desired image value. In an example, digital pixel values corresponding to a first row of pixels are processed so that the data ramp signal is applied to each pixel of the first row at transition times determined by the digital image values associated with each pixel. While the digital image values of the first row of pixels are processed, digital pixel values corresponding to a second row of pixels are received and stored for processing after processing of the first row is complete.
