Low-Power Techniques for LCD Applications
Low power is often a requirement in LCD applications. The low-power features of PIC microcontrollers and the ability to drive an LCD directly can help in meeting this requirement. While the LCD driver module makes driving LCDs very easy, there are important factors to take into account in configuring the module.
Two specific factors that affect power consumption are the resistor ladder, which generates the bias voltages for the LCD waveforms, and the clock source configuration. By intelligently selecting a resistor ladder size and clock source best suited for the application, an LCD application using PIC microcontrollers can be optimized for low power.
