Abstract

A device and method for eliminating an image border of electrophoretic electronic paper includes the following steps: S1, acquiring gray-scale driving waveform information and gray-scale position information, wherein the driving waveform information comprises a level value and a duration corresponding thereof; S2, outputting regulation waveform information based on an termination level value of a first gray scale, a level duration and a starting level value of a second gray scale, wherein the regulation waveform information comprises a level value, an embedding time and an embedding position of a waveform; and S3, modifying the gray-scale driving waveform information based on the regulation waveform information, and controlling an output of a drive electrode based on the modified gray-scale driving waveform information. By using the device and method, an impact of the fringe electric field on movement of electronic paper micro-capsules is eliminated, thus effectively reducing border ghosting.

Description

technical field [0001] The invention relates to a method and a device for eliminating the image boundary of electrophoretic electronic paper, belonging to the field of electrophoretic display. Background technique [0002] At present, the electrophoretic electronic paper display technology is becoming more and more mature, and the application scenarios of electrophoretic electronic paper are becoming more and more common, such as: electronic labels, billboards, electronic school bags, electronic watches, electronic readers, flexible display devices, etc. Electrophoretic electronic paper has a series of advantages, such as: good bistable display characteristics, low power consumption, reflective paper-like display, easy to realize flexible display, etc. Its paper-like display characteristics are popular among users and make it a The first choice for long reading. [0003] However, the driving waveform of electrophoretic e-paper still needs to be further optimized to improve ...
