Abstract
A display device may include a plurality of pixels that display image data on a display, a digital-to-analog converter that outputs a voltage that corresponds to a luminance value to be depicted on a first pixel, and a circuit that amplifies the voltage and outputs an amplified voltage to the first pixel. The circuit may include a capacitor that receives the voltage via the digital-to-analog converter and an amplifier coupled to the capacitor. The amplifier generates the amplified voltage based on the voltage stored the capacitor. The circuit also include switches that couple a first terminal of the capacitor to an output of the amplifier during a first amount of time and couples a second terminal of the capacitor to the output of the amplifier after the first amount of time expires.
