Fundamental physics and operational principles for full-color e-paper
摘要
Abstract
As a promising reflective display technology, electrophoretic display (EPD) has been widely applied in low power consumption display devices such as e-reader.Despite of the commercial success of monochromic EPD, the future display application needs to be full-color.However, some challenges still obstruct the development of commercial full-color EPD.This paper will first introduce fundamental operation mechanism of EPD, such as particles charging mechanism and particles surface treatment.Then the driving waveform is discussed to improve EPD's performance in order to resolve the ghosting and reflectance overshooting phenomenon.We managed to eliminate the reflectance overshooting at the cost of only 4％ of the peak reflectance.Also, different strategies for achieving fullcolor EPD are presented as well as a transfer method.We successfully prepared 300×300 μm color microcapsules sub-pixel array and realized a color electrophoretic EPD.The NTSC ratio of our EPD reached 13.7％for three subpixels structure, which is larger than 3.14％ of the color filter based EPD reported elsewhere.关键词
