Abstract
Electrophoretic displays (EPDs) have become the main solution to electronic paper
because of its invariably reflective and bistable properties. With different
requirements of display resolution, speed, and contrast ratio, the electronic paper
(E-Paper) designers may adopt different types of electrophoretic material and active
matrix backplane for building the system. The driving waveforms should be also
customized for accommodating different application specifications and environment
temperature. In this paper, we present a configurable EPD controller which can support
various application specifications. In addition to providing a new architecture of
compacted waveform lookup tables, the controller supports partial image update and
integrates a real-time halftoning engine for improving image quality. The design has
been implemented on a field-programmable gate array (FPGA) and tested with several real
EPDs.
