Abstract
A plasma display device having three-electrode pixels. Each pixel may be set either in a write state or in a sustain state by a pair of select electrodes. In the write state the pixel may be set either ON or OFF. A pixel is put in a write state when the AC signals applied to the select electrodes are in phase. Once the signals applied to the select electrodes are in phase, the pixel may be set ON or OFF depending on the phase of the signal applied to a data electrode. In the sustain state the pixel remains either ON or OFF regardless of the signal applied to the data electrode. A pixel is put in a sustain state when out-of-phase signals are applied to the pair of select electrodes. The pixels in the display are arranged in rows and columns. Each pixel column has a single data electrode, and each pixel row has a pair of select electrodes associated with it. Pixels in unselected rows may be illuminated concurrently with the writing into pixels in selected rows. In order to avoid crosstalk and high electric fields generated between a select electrode of one pixel and a select electrode of an adjacent pixel, adjacent pixel rows may share a select electrode.
