Improvements of Nonuniform Optical Response for QR-LPD
  DOI :  10.2352/J.ImagingSci.Technol.2013.57.1.010501  Published OnlineJanuary 2013

Abstract A quick-response liquid powder display (QR-LPD) is a favorable candidate for flexible electronic paper since it provides an affordable plastic panel fabrication. However, significant image noise is perceived on QR-LPDs. In this article, we discuss the root causes of nonuniform optical response and powder clustering. We propose an image compensation system to improve the nonuniform optical response. The experiment results show improvements in the mean-square signal-to-noise ratio of over 8.6 dB, with an average improvement of 4.6 dB.
