A plasma display panel (PDP) is a type of flat panel display that uses small cells containing plasma; ionized gas that responds to electric fields. Until about 2007, plasma displays were commonly used in larger televisions (30 inches (76 cm) and larger). Since then, they have lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays. Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016.

This utility model relates to the field of electronic paper display technology, specifically to a plasma display module with a polymer dielectric coating, comprising: a first substrate and a second substrate, the second substrate being disposed opposite to the first substrate, forming a plasma display cavity between the first and second substrates, the plasma display cavity being filled with plasma particles; a pixel electrode layer is disposed on the surface of the second substrate facing the first substrate, a filter layer is disposed on the surface of the first substrate facing the second substrate, and a conductive dielectric layer is disposed on the surface of the filter layer facing the second substrate; a polymer dielectric coating is disposed on the surface of the conductive dielectric layer facing the second substrate or the surface of the pixel electrode layer facing the first substrate. The polymer dielectric coating in this utility model possesses the characteristics of strong vertical conductivity and weak horizontal conductivity, which can effectively reduce the oblique electric field and help particles move orderly between the upper and lower substrates, thereby eliminating image retention.
