Abstract
A display device may include rows of pixels that displays image data on a display, data lines coupled to the rows of pixels, and a digital-to-analog converter (DAC) that outputs a ramp voltage signal including a data voltage to be depicted on a first pixel of the rows of pixels. The display device may also include a capacitor that receives the ramp voltage signal via the DAC and a circuit that sends a control signal to a circuit component that causes the DAC to couple to the capacitor via one of the data lines for a duration of time that comprises a first time when the ramp voltage signal is below the data voltage and a second time when the ramp voltage signal is approximately equal to the data voltage. The capacitor is coupled to the DAC when the ramp voltage signal is greater than zero.
