3results about How to "Eliminate afterimage" patented technology

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.

This disclosure provides a display processing method, apparatus, and display device, belonging to the field of display technology. The display processing apparatus is applied to a display device, the display area of ​​which includes color sub-pixels and white sub-pixels. The apparatus includes: an acquisition module, configured to, when the display device is in video playback mode, acquire a first value of at least one first parameter of a preset area of ​​the display area, the first parameter corresponding to a driving transistor of a pixel driving circuit of the preset area, the value of the first parameter being proportional to the threshold voltage of the corresponding driving transistor; after a first preset time period, acquire a second value of each first parameter; a determination module, configured to determine a target area based on the difference between the second value and the first value, wherein at least a portion of the first parameters of the target area have a difference greater than a first preset threshold; and a processing module, configured to reduce the brightness of the color sub-pixels of the target area. The technical solution of this disclosure can eliminate image retention in display devices.
