Abstract
A display plasma module with a double-layer microstructure includes a pixel electrode and a transparent electrode located above the pixel electrode. A display plasma and a liner frame surrounding the display plasma are arranged between the pixel electrode and the transparent electrode. A plasma barrier array used for uniformly dispersing and stabilizing the display plasma is arranged on the pixel electrode and/or the transparent electrode, and a spacer particle layer is adsorbed on the plasma barrier array. The display plasma module directly uses the display plasma to replace the micro-cup structure or the microcapsule structure, and is provided with the plasma barrier array and the spacer particle layer used for uniformly dispersing, stabilizing and isolating the display plasma, which has a function of supporting the whole display plasma module and controlling the thickness of the display plasma.
