摘要
The paper-like cholesteric liquid crystal display (Ch-LCD) has become the next generation of electronic readers in consuming market. The embedded fully symmetric self-biased switched-capacitor (FSSBSC) with single-inductor high voltage bipolar-output (SIHBO) converter is proposed to achieve the energy and area-efficient driving scheme. As the compact power management module, SIHBO converter can provide +/−35V bipolar outputs for row driving. In addition, the embedded FSSBSC is utilized to generate the different voltage levels for modulating the gray-color in column driving scheme. This combination carries out the effective driving operation for Ch-LCD through the demand of timing control unit. Simulated results show the achievement of +/−35V output voltage in the SIHBO converter and the variety voltage levels generated from FSSBSC. The peak efficiency is derived of 85% with the integrated chip area of 6.53 mm2.
