Abstract
Systems, devices, and methods for reducing common voltage loading and/or enabling a simplified manner of polarity inversion in liquid crystal display (LCD) devices are provided. In accordance with one embodiment, a device may include a processor, a memory device, and a liquid crystal display having a pixel array including rows and columns of pixels. The pixels of each row of the pixel array may be configured to cause an approximately even amount of common voltage loading to be shared between one of a first plurality of common electrodes and one of a second plurality of common electrodes when the pixels of each row of the pixel array receive a scanning signal and a data signal.
