Abstract
The present invention belongs to the field of electronic display technology, and relates to a display plasma module and a manufacturing method thereof, characterized in that a display plasma module includes 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, and a spacer frame is located around the display plasma. In the present invention, the display plasma is used to replace the existing micro-cup structure or microcapsule. Compared to the traditional electrophoretic display screen with microstructure, the thickness is reduced, the contrast is increased by more than 10%, and the response time is reduced to less than 80 milliseconds, so that the manufacturing process is simpler, the yield is improved, and the manufacturing cost is reduced.
