Electrophoretic displays with dielectric coatings on electrodes

An electrophoretic display (100) includes an electrophoretic medium (114) having charged particles disposed in a fluid and capable of moving through the fluid upon application of an electric field. An electrode (104, 120) is disposed adjacent the electrophoretic medium and is configured to apply an electric field to the electrophoretic medium. A dielectric layer (106, 118) is disposed between the electrophoretic medium (114) and the electrode (104, 120) and has at least one aperture (107, 119) extending therethrough. Providing holes (107, 119) in the dielectric layer enables the dielectric layer (106, 118) to protect the electrodes (104, 120) while reducing electro-optic backlash. When a plurality of electrodes (104, 120) are present adjacent the electrophoretic medium (114), more than one or all of the electrodes (104, 120) may be provided with a porous dielectric layer (106, 118). 一种电泳显示器(100)，包括电泳介质(114)，该电泳介质具有布置在流体中并且能够在施加电场时移动穿过流体的带电粒子。电极(104、120)邻近电泳介质布置并且设置为对电泳介质施加电场。介电层(106、118)布置在电泳介质(114)与电极(104、12
