electrophoretic display panel

摘要

The electrophoretic display panel ( 1 ) for displaying a picture corresponding to image information has drive means ( 100 ) which are able to control for each picture element ( 2 ) the potentials, thereby being able to change the position of the particles ( 6 ) based on the image information. Furthermore, the display panel ( 1 ) has monitoring means ( 101 ) which are able to generate for each picture element ( 2 ) actual position information indicative for the actual position of the particles ( 6 ), and control means ( 103 ) which are able to control for each picture element ( 2 ) the drive means ( 100 ) in dependence of the actual position information and the image information to reduce a difference between the position of the particles ( 6 ) and the position off the particles ( 6 ) corresponding to the image information. For the display panel ( 1 ) to be able to provide a picture of relatively high quality even at relatively low or nonuniform intensities of the ambient light, the monitoring means ( 101 ) comprise electrical means ( 102 ) which are able to generate for each picture element ( 2 ) the actual position information based on an electrical property of the respective picture element ( 2 ).
