Abstract:
Systems, devices, and methods for reducing direct current bias 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. Each pixel of the pixel array may include a pixel electrode separated from a common electrode by a dielectric passivation layer, and may include a transistor to provide a data signal when the transistor is activated. The pixel array is configured such that a neutral amount of direct current bias is generated on the passivation layer when each row of pixels is activated. The common electrodes of certain pixels may be disposed above their respective pixel electrodes, while the common electrodes of certain other pixels may be disposed below their respective pixel electrodes.
