Circuit provides effective LCD drive


Posted on Feb 16, 2013

The circuit in Figure 1 is an effective driver for LCDs. The circuit comprises two main sectionsthe ICM7211 drivers (IC2 and IC3) and the YN06 display itself (IC1). The Intersil (www.intersil.com) ICM7211 is a 4-bit LCD driver that needs no external components. It contains three basic sections: a reference signal-generator circuit, an input and display-channel section, and a digit-selection and drive circuit.



It contains a complete pulse-generator unit and an oscillator-divider clock-drive circuit. When you disconnect the BP pin (Pin 5), the IC produces a 125-Hz pulse signal. YN06 is a six-bit character LCD, which uses 5 decimal bits and 2 column bits. To cont
