AN87391 - PSoC® 4 Segment LCD Direct Drive
Introduction
Most low-power portable handheld devices such as glucose meters, multimeters, and blood pressure monitors use a segment LCD to display information. Segment LCDs require an external driver to interface with a microcontroller. PSoC 4 implements an integrated low-power LCD driver that can directly drive segment LCD glass.
