Abstract
The electrophoretic image display (EPID) is a passive display technique based upon the scattering and absorption of ambient light. This paper will review the present status of EPID technology with emphasis on developments at Philips Laboratories. The nature and requirements of the colloidal suspension i.e., the pigment particles suspended in a dyed nonaqueous liquid, that constitutes the working medium of an EPID device will be discussed. A description of the optical, electrical, and hydrodynamic characteristics of EPID devices will be presented. Fabrication methods, device degradation modes, and the status of x-y addressing techniques will be described.Keywords
