Abstract

A system may include buffer circuitry that receives an input signal representative of image data for display via a pixel. The buffer circuitry may provide a first driving signal during a first frame of the image data to the pixel based on the input signal. The buffer circuitry may include slew booster circuitry. The slew booster circuitry may supply a voltage boost (e.g., additional voltage) to differential pair stage circuitry of the buffer circuit in response to a difference between the input signal and a second driving signal exceeding a threshold increase a rate of change of the input signal provided. The second driving signal may be provided to the pixel during a second frame of the image data preceding the first frame.
