Abstract
The present invention belongs to the field of electronic display technology, and relates to a display plasma module with a patterned structure, including a pixel electrode and a transparent electrode located above the pixel electrode, characterized in that a display plasma is provided between the pixel electrode and the transparent electrode. A spacer frame is located around the display plasma. A plasma barrier array for uniformly dispersing and stabilizing the display plasma is provided on the pixel electrode and/or the transparent electrode. The plasma barrier array includes a plurality of plasma barrier frames distributed in an array. The display plasma module of the present invention replaces the existing micro-cup structure or microcapsule with the display plasma, and the plasma barrier array for uniformly dispersing and stabilizing the display plasma is provided in the display plasma.
