Abstract:
Methods and devices employing zero-bias display turn-off circuitry, including turn-off logic and switching devices, are provided. In one example, a method may include supplying a common voltage output of ground to a common electrode of a pixel of an electronic display, supplying an activation signal to the pixel to activate the pixel, supplying a data signal of ground to a pixel electrode of the pixel, and removing the activation signal from the pixel while the data signal is being supplied to the pixel to store the data signal in the pixel. When the activation signal is removed, the method may include causing the common voltage output being supplied to the common electrode of the pixel to change to a floating value to prevent a kickback voltage from affecting the data signal stored in the pixel.
